Capital, savings, and investment are taken up in the fourth section, which explains how the long-term growth of any economy depends upon the relationship between investments in capital goods (inventories and the facilities and equipment used to make products) and the level of saving in that economy. The next section explains the role money and financial markets play in the economy. Labor markets, the topic of section six, are also extremely important in the

Producers decide which goods and services to make and sell, and how much to ask for those products. At the same time, consumers decide what they will purchase and how much money they are willing to pay for different goods and services. The interaction between competing producers, who attempt to make the highest possible profit, and consumers, who try to pay as little as possible to acquire what they want, ultimately determines the price of goods and services.
In a market economy, government plays a limited role in economic decision making. However, the
Factors of Production
The factors of production, which in the
Natural Resources
Natural resources, which come directly from the land, air, and sea, can satisfy people’s wants directly (for example, beautiful mountain scenery or a clear lake used for fishing and swimming), or they can be used to produce goods and services that satisfy wants (such as a forest used to make lumber and furniture).
The
Labor
Labor refers to the routine work that people do in their jobs, whether it is performing manual labor, managing employees, or providing skilled professional services. Manual labor usually refers to physical work that requires little formal education or training, such as shoveling dirt or moving furniture. Managers include those who supervise other workers. Examples of skilled professionals include doctors, lawyers, and dentists.
Of the 270 million people living in the
Capital
Capital includes buildings, equipment, and other intermediate products that businesses use to make other goods or services. For example, an automobile company builds factories and buys machines to stamp out parts for cars; those buildings and machines are capital. The value of capital goods being used by private businesses in the
Entrepreneurship
Entrepreneurship is an ability some people have to accept risks and combine factors of production in order to produce goods and services. Entrepreneurs organize the various components necessary to operate a business. They raise the necessary financial backing, acquire a physical site for the business, assemble a team of workers, and manage the overall operation of the enterprise. They accept the risk of losing the money they spend on the business in the hope that eventually they will earn a profit. If the business is successful, they receive all or some share of the profits. If the business fails, they bear some or all of the losses.
Many people mistakenly believe that anyone who manages a large company is an entrepreneur. However, many managers at large companies simply carry out decisions made by higher-ranking executives. These managers are not entrepreneurs because they do not have final control over the company and they do not make decisions that involve risking the companies resources. On the other hand, many of the nation’s entrepreneurs run small businesses, including restaurants, convenience stores, and farms. These individuals are true entrepreneurs, because entrepreneurship involves not merely the organization and management of a business, but also an individual’s willingness to accept risks in order to make a profit.
Throughout its history, the United States has had many notable entrepreneurs, including 18th-century statesman, inventor, and publisher Benjamin Franklin, and early-20th-century figures such as inventor Thomas Edison and automobile producer Henry Ford. More recently, internationally recognized leaders have emerged in a number of fields: Bill Gates of Microsoft Corporation and Steve Jobs of Apple Computer in the computer industry; Sam Walton of Wal-Mart in retail sales; Herb Kelleher and Rollin King of Southwest Airlines in the commercial airline business; Ray Kroc of MacDonald’s, Harland Sanders of Kentucky Fried Chicken (KFC), and Dave Thomas of Wendy’s in fast food; and in motion pictures, Michael Eisner of the Walt Disney Company as well as a number of entrepreneurs at smaller independent production studios that developed during the 1980s and 1990s.
Acquiring the Factors of Production
All four factors of production—natural resources, labor, capital, and entrepreneurship—are traded in markets where businesses buy these inputs or productive resources from individuals. These are called factor markets. Unlike a grocery market, which is a specific physical store where consumers purchase goods, the markets mentioned above comprise a wide range of locations, businesses, and individuals involved in the exchange of the goods and services needed to run a business.
Businesses turn to the factor markets to acquire the means to make goods and services, which they then try to sell to consumers in product or output markets. For example, an agricultural firm that grows and sells wheat can buy or rent land from landowners. The firm may shop for this natural resource by consulting real estate agents and farmers throughout the
Firms often buy new factories and machines from other firms that specialize in making these kinds of capital goods. That kind of investment often requires millions of dollars, which is usually financed by loans from banks or other financial institutions.
Entrepreneurship is perhaps the most difficult resource for a firm to acquire, but there are many examples of even the largest and most well-established firms seeking out new presidents and chief executive officers to lead their companies. Small firms that are just beginning to do business often succeed or fail based on the entrepreneurial skills of the people running the business, who in many cases have little or no previous experience as entrepreneurs.
Markets and the Problem of Scarcity
A basic principle in every economic system—even one as large and wealthy as the U.S. economy—is that few, if any, individuals ever satisfy all of their wants for goods and services. That means that when people buy goods and services in different markets, they will not be able to buy all of the things they would like to have. In fact, if everyone did have all of the things they wanted, there would be no reason for anyone to worry about economic problems. But no nation has ever been able to provide all of the goods and services that its citizens wanted, and that is true of the
Scarcity is also the reason why making good economic choices is so important, because even though it is not possible to satisfy everyone’s wants, all people are able to satisfy some of their wants. Similarly, every nation is able to provide some of the things its citizens want. So the basic problem facing any nation’s economy is how to make sure that the resources available to the people in the nation are used to satisfy as many as possible of the wants people care about most.
The
Not surprisingly, low-income families would like to receive more income, and often favor higher taxes on upper-income households. But many upper-income families complain that government already taxes them too much, and some argue that government is taking over too many things in the economy that were, in the past, left up to individuals, families, and private firms or charities.
These debates take place because of the problem of scarcity. For individuals and governments, resources that satisfy a particular want cannot be used to satisfy other wants. Therefore, deciding to satisfy one want means paying the cost of not satisfying another. Such choices take place every time the government decides how to spend its tax revenues.
What Are Markets?
Goods and services are traded in markets. Usually a market is a physical place where buyers and sellers meet to make exchanges, once they have agreed on a price for the product. One kind of marketplace is a grocery store, where people go to buy food and household products. However, many marketsare not confined tospecific locations. In a broader sense, markets include all the places and sources where goods and services are exchanged. For example, the labor market does not exist in a specific physical building, as does a grocery market. Instead, the term labor market describes a multitude of individuals offering their labor for sale as well as all the businesses searching for employees.
Traders do not always have to meet in person to buy and sell. Markets can operate via technology, such as a telephone line or a computer site. For example, stocks and other financial securities have long been traded electronically or by telephone. It is becoming increasingly common in the
How a Single Market Works
Buyers hope to buy at low prices and will purchase more units of a product at lower prices than they do at higher prices. Sellers are just the opposite. They hope to sell at high prices, and typically they will be willing to produce and sell more units of a product at higher prices than at lower prices.
The price for a product is determined in the market if prices are allowed to rise and fall, and are not legally required to be above some minimum price floor or below some maximum price ceiling. When a product, for example, a personal computer, reaches the market, consumers learn what producers want to charge for it and producers learn what consumers are willing to pay. The interaction of producers and consumers quickly establishes what the market price for the computer will actually be. Some people who were considering buying a computer decide that the price is higher than they are willing to pay. And some producers may determine that consumers are not willing to pay a price high enough for them profitably to produce and sell this computer.
But all of the buyers who are willing and able to pay the market price get the computer, and all of the sellers willing and able to produce it for this price find buyers. If more consumers want to buy a computer at a specific market price than there are suppliers are willing to sell at that price—or in other words, if the quantity demanded is greater than the quantity supplied—the price for the computer increases. When producers try to sell more of their computers at a price higher than consumers are willing to buy, the quantity supplied exceeds the quantity demanded and the price falls.
The price stops rising or falling at the price where the amount consumers are willing and able to buy is just equal to the amount sellers are willing and able to produce and sell. This is called the market clearing price. Market clearing prices for many goods and services change frequently, for reasons that will be discussed below. But some market prices are stable for long periods of time, such as the prices of candy bars and sodas sold in vending machines, and the prices of pizzas and hamburgers. Most buyers of these products have come to know the general price they will have to pay for these items. Sellers know what prices they can charge, given what consumers will pay and considering the competition they face from other sellers of identical, or very similar, products.
How markets determine price is simple enough to understand for a single good or service in a single location. But consider what happens when there are markets for nearly all of the goods and services produced and consumed in an economy, across the entire country. In that context, this reasonably simple process of setting market prices allows an economic system as large and complex as the
Efficiency here means producing what consumers want to buy, at prices that are as low as they can be for producers to stay in business. And it turns out this efficiency is directly linked to the freedom that buyers and sellers have in a market economy. No central authority has to decide how many shirts or cars or sandwiches to produce each day, or where to produce them, or what price to charge for them. Instead, consumers spend their money for the products that give them the most satisfaction, and they try to find the best deal they can in terms of price, quality, convenience, assurances that defective products will be replaced or repaired, or other considerations.
What consumers are willing and able to buy tells producers what they should produce, if they hope to make a profit. Usually consumers have many options to choose from, because more than one producer offers the same or reasonably similar products (such as two or more kinds of cars, colas, and carpets). Producers then compete energetically for the dollars that consumers spend.
Competition among producers determines the best ways to produce a good or service. For example, in the early 1900s automobiles were made largely by hand, one at a time. But once Henry Ford discovered how to lower the cost of producing cars by using assembly lines, other car makers had to adopt the same production methods or be driven out of business (as many were).
Competition also determines what features and quality standards go into products. And competition holds down the costs of production because producers know that consumers compare their prices to the prices charged by other firms and for other products they might buy. In markets where a large number of producers compete, inefficient producers will be driven out of the market.
For example, at one time most towns and cities had independently owned cafes and drive-in restaurants that sold hamburgers, french fries, and soft drinks. Some of these businesses are still operating, but many closed down after larger fast-food chains began opening local franchises all around the nation, with well-known product standards and relatively low prices. The increased competition led to prices that were too low for many of the old cafes and drive-ins to make a profit. The private cafes that did survive were able to meet that level of efficiency, or they managed to make their products different enough from the national chains to keep their customers.
Prices for goods and services can only fall so far, however. Even the most efficient producers have to pay for the natural resources, labor, capital, and entrepreneurship they use to make and sell products. The market price cannot stay below the level of those costs for long without driving all of the producers out of this market. Therefore, if consumers want to buy some good or service not just today but also in the future, they have to pay a price at least high enough to cover the costs of producing it, including enough profit to make it worthwhile for sellers to stay in that market.
Once market prices for various goods and services are set, consumers are free to choose what to buy, and producers are free to choose what to produce and sell. They both follow their self-interest and do what makes them as well off as they can be. When all buyers and sellers do that in an economic system of competitive markets, the overall economy will also be very efficient and responsive to individual preferences.
This economic process is extremely decentralized. For example, it is likely that no one person or government agency knows how many corned beef sandwiches are sold in any large
Consumers usually do not make up their mind about what to eat for lunch or dinner until they walk into the restaurant, grocery store, or sandwich shop. But they know they can go to several different places and choose many different things to eat and drink, while individual sellers know about how much they are likely to sell on an average business day.
Other businesses sell bread and meat and drinks to the restaurants and grocers, but they do not really know how many different sandwiches the different food stores are selling either. They only know how much bread and meat they need to have on hand to satisfy the orders they get from their customers.
Each buyer and seller knows his or her small part of the market very well and makes choices carefully to avoid wasting money and other resources. When everyone acts this carefully while facing competition from other consumers or producers, the overall system uses its scarce resources very efficiently. Efficiency implies two things here: taking into account the preferences and alternative choices that individual buyers and sellers face, and producing goods and services at the lowest possible cost.
How and Why Market Prices Change
Another advantage of any competitive market system is a high level of flexibility and speed in responding to changing economic conditions. In economies where government agencies and central planners set prices, it often takes much longer to adjust prices to new conditions. In the last decades of the 20th century, the
Market prices change whenever something causes a change in demand (the amount people are willing to buy at different prices) or a change in supply (the amount producers are willing and able to make and sell at different prices). see Supply and Demand. Because these changes can occur rapidly, with little or no advance warning, it is important for both consumers and producers to understand what can cause prices to rise and fall. Those who anticipate price changes correctly can often gain financially from their foresight. Those who do not understand why prices have changed are likely to feel bewildered and frustrated, and find it more difficult to know how to respond to changing prices. Market economies are, in fact, sometimes called price systems. It is important to understand why prices rise and fall to understand how a market system works.
Changes in Demand
Demand for most products changes whenever there is a significant change in the level of consumers’ income. In the
Demand for a product also changes when the price of a substitute product changes. For example, if the price for one brand of blue jeans sharply increases while other brands do not, many consumers will switch to the other brands, so the demand for those brands will increase. Conversely, if the price for beef drops, then many people will buy less pork and chicken.
Some products are complements rather than substitutes. Complements are products that are consumed together, for example cameras and film, or tennis balls and tennis rackets. When the price of a complementary good rises, the demand for a product falls. For example, if the price of cameras rises, the demand for film will fall. On the other hand, if the price of a complementary good falls, the demand for a product will rise. If the price of tennis rackets falls, for example, more people will buy rackets and the demand for tennis balls will increase.
Demand can also increase or decrease as a product goes in or out of style. When famous athletes or movie stars create a popular new look in clothing or tennis shoes, demand soars. When something goes out of style, it soon disappears from stores, and eventually from people’s closets, too.
If people expect the price of something to go up in the future, they start to buy more of the product now, which increases demand. If they believe the price is going to fall in the future, they wait to buy and hope they were right. Sometimes these choices involve very serious decisions and large amounts of money. For example, people who buy stocks on the stock market are hoping that prices will rise, while at least some of the people selling those stocks expect the prices to fall. But not all economic decisions are this serious. For example, in the 1970s there was a brief episode when toilet paper disappeared from the shelves of grocery stores, because people were afraid that there were going to be shortages and rising prices. It turns out that some of these unfounded fears were based on remarks made by a comedian on a late-night talk show.
The final factor that affects the demand for most goods and services is the number of consumers in the market for a product. In cities where population is rising rapidly, the demand for houses, food, clothing, and entertainment increases dramatically. In areas where population is falling—as it has in many small towns where farm populations are shrinking—demand for these goods and services falls.
Changes in Supply
The supply of most products is also affected by a number of factors. Most important is the cost of producing products. If the price of natural resources, labor, capital, or entrepreneurship rises, sellers will make less profit and will not be as motivated to produce as many units as they were before the cost of production increased. On the other hand, when production costs fall, the amount producers are willing and able to sell increases.
Technological change also affects supply. A new invention or discovery can allow producers to make something that could not be made before. It could also mean that producers can make more of a product using the same or fewer inputs. The most dramatic example of technological change in the
Opportunities to make profits by producing different goods and services also affect the supply of any individual product. Because many producers are willing to move their resources to completely different markets, profits in one part of the economy can affect the supply of almost any other product. For example, if someone running a barbershop decided to sign a contract to provide and operate the machines that clean runways at a large airport, this would decrease the supply of haircutting services and increase the supply of runway sweeping services.
When suppliers believe the price of the good or service they provide is going to rise in the future, they often wait to sell their product, reducing the current supply of the product. On the other hand, if they believe that the price is going to fall in the future, they try to sell more today, increasing the current supply. We see this behavior by large and small sellers. Examples include individuals who are thinking about selling a house or car, corn and wheat farmers deciding whether to sell or store their crops, and corporations selling manufactured products or reserves of natural resources.
Finally, the number of sellers in a market can also affect the level of supply. Generally, markets with a larger number of sellers are more competitive and have a greater supply of the product to be sold than markets with fewer sellers. But in some cases, the technology of producing a product makes it more efficient to produce large quantities at just a few production sites, or perhaps even at just one. For example, it would not make sense to have two or more water and sewage companies running pipes to every house and business in a city. And automobiles can be produced at a much lower cost in large plants than in small ones, because large plants can take greater advantage of assembly-line production methods.
All these different factors can lead to changes in what consumers demand and what producers supply. As a result, on any given day prices for some things will be rising and those for others will be falling. This creates opportunities for some individuals and firms, and problems for others. For example, firms producing goods for which the demand and the price are falling may have to lay off workers or even go out of business. But for the economy as a whole, allowing prices to rise and fall quickly in response to changes in any of the market forces that affect supply and demand offers important advantages. It provides an extremely flexible and decentralized system for getting goods and services produced and delivered to households while responding to a vast number of unpredictable changes.
Creative Destruction
Taking advantage of new opportunities while curtailing production of things that are no longer in demand or no longer competitive was described as the process of creative destruction by 20th century Austrian-American economist Joseph Schumpeter. For example, Schumpeter discussed how the
In the modern world, prices change not only as a result of things that happen in one country, but increasingly because of changes that happen in other countries, too. International change affects production patterns, wages, and jobs in the

Many people think the most important general issue facing the
PRODUCTION OF GOODS AND SERVICES
Before goods and services can be distributed to households and consumed, they must be produced by someone, or by some business or organization. In the
Successful firms earn profits for their owners, who accept the risk of losing money if the products the firms try to sell are not purchased by consumers at prices high enough to cover the costs of production. In the modern economy, most firms and workers have found that to be competitive with other firms and workers they must become very good at producing certain kinds of goods and services.
Most businesses in the
Specialization and the Division of Labor
In earlier centuries, especially in frontier areas, families in the
Over the years, most people and businesses realized that they could make better use of their time and resources by concentrating on one particular kind of work, rather than trying to produce for themselves all the items they want to consume. Most people now work in jobs where they do one kind of work; they are carpenters, bankers, cooks, mechanics, and so forth. Likewise, most businesses produce only certain kinds of goods or services, such as cars, tacos, or gardening services. This feature of production is known as specialization. A high degree of specialization is a key part of the economic system in the
At almost all businesses, when goods and services are produced, labor is divided among workers, with different employees responsible for completing different tasks. This is known as division of labor. For example, the individual parts of cars and televisions are made by many different workers and then put together in an assembly line. Other well-known examples of this specialization and division of labor are seen in the production of computers and electrical appliances. But even kitchens in large restaurants have different chefs for different items, and professional workers such as doctors and dentists have also become more specialized during the past century.
Advantages of Specialization
By specializing in what they produce, workers become more expert at a particular part of the production process. As a result, they become more efficient in these jobs, which lowers the costs of production. Specialization also makes it possible to develop tools and machines that help workers do highly specialized tasks. Carpenters use many tools that plumbers and painters do not. Commercial bakeries have much larger ovens and mixers than those used by people who only bake bread and pies once a year. And unlike a household kitchen, a commercial bakery has machines to slice and package bread. All of these tools and machines help workers and businesses produce more efficiently, and lower the cost of producing goods and services.
The advantages of specialization have led to the creation of many very large production facilities in the
When the market for a product is very large, and a company can sell enough goods or services in that market to support a very large production facility, it will often choose to produce on a large scale to take advantage of specialization and division of labor. As long as producing more in larger facilities lowers the average costs of production, the producer enjoys what are known as economies of scale.
But bigger is not always better, and eventually almost all producers encounter diseconomies of scale in which larger plants or production sites become less efficient and more costly to operate. Usually that happens because monitoring and managing increasingly larger production facilities becomes more difficult. That is why most large manufacturers have more than one factory to make their products, instead of one massive facility where they make everything they produce. In recent years, many steel companies have found it more efficient to build and operate smaller steel mills than they once operated.
Specialization and International Trade
Over the past few decades, international trade has led to greater specialization and competition among producers in the
International trade is a dramatic way of expanding the size of a firm’s market. In markets where transportation costs are low compared with the selling price of a product, it has become possible for producers to compete globally to take full advantage of highly specialized production. But international trade also means that businesses must compete more efficiently against firms from all around the world. That competition also makes them try to take advantage of greater specialization and the division of labor.
In many cases, products are produced and sold by firms from two or more countries that have large production and employment levels in the same industry. Often, however, these firms still specialize in the kinds of products they produce. For example, though many small cars and small pickup trucks are made in
Transportation costs can also help to explain the pattern of international production and trade. It often makes sense to produce goods close to the markets where they will be sold, or close to where the resources used in the production process are found or made. In recent years, the availability of a skilled and hard-working labor force has become more important to producers in many different industries, so new factories are often located in areas with large numbers of well-trained workers and good schools that provide a future supply of well-educated workers.
Production Patterns: Past, Present, and Future
Several dramatic changes in production patterns occurred in the
Technological changes in the transportation, communications, and computer industries created entirely new kinds of jobs and businesses, and altered the kinds of skills workers were expected to have in many others. World trade led to increased specialization and competition, as businesses adapted to meet the demands of international competition.
Perhaps the greatest change in the
As a result of these developments, the closing decades of the 20th century saw a dramatic increase in service industries in the

During the 20th century, businesses and their workers had to adjust to many changes in the kinds of goods and services people demanded. These changes naturally led to changes in where jobs were available, and in what kinds of education, training, and skills employees were expected to have. As the base of employment in the
Public Policies to “Protect” Firms and Workers
Historically in the
Although direct financial assistance to corporations has been rare, the government has provided subsidies or partial protection from international competition to a large number of industries. Economic analysis of these programs rarely finds such subsidies and protection to be a good idea for the nation as a whole, though naturally the companies and workers who receive the support are better off. But usually these programs result in higher prices for consumers, higher taxes, and they hurt other
For example, in the 1980s the
It is simply not possible to subsidize and protect everyone in the
When the special protection or support is removed, the adjustments that producers and workers often have to make then can be much more severe than they would have been when the government programs were first adopted. That has happened when price support programs for milk and other agricultural products were phased out, and when policies that subsidized
For these reasons, if public assistance is provided to a particular industry, economists are likely to favor only temporary payments to cover some of the costs of relocation and retraining of workers. That policy limits the cost of such assistance and leaves workers and firms free to move their resources into whatever opportunities they believe will work best for them.
Most producers in the
CORPORATIONS AND OTHER TYPES OF BUSINESSES
Three major types of firms carry out the production of goods and services in the
Proprietorships and Partnerships
Sole proprietorships are typically owned and operated by one person or family. The owner is personally responsible for all debts incurred by the business, but the owner gets to keep any profits the firm earns, after paying taxes. The owner’s liability or responsibility for paying debts incurred by the business is considered unlimited. That is, any individual or organization that is owed money by the business can claim all of the business owner’s assets (such as personal savings and belongings), except those protected under bankruptcy laws.
Normally when the person who owns or operates a proprietorship retires or dies, the business is either sold to someone else, or simply closes down after any creditors are paid. Many small retail businesses are operated as sole proprietorships, often by people who also work part-time or even full-time in other jobs. Some farms are operated as sole proprietorships, though today corporations own many of the nation’s farms.
Partnerships are like sole proprietorships except that there are two or more owners who have agreed to divide, in some proportion, the risks taken and the profits earned by the firm. Legally, the partners still face unlimited liability and may have their personal property and savings claimed to pay off the business’s debts. There are fewer partnerships than corporations or sole proprietorships in the
Corporations
In the
Limited Liability
The key feature of corporations is limited liability. Unlike proprietorships and partnerships, the owners of a corporation are not personally responsible for any debts of the business. The only thing stockholders risk by investing in a corporation is what they have paid for their ownership shares, or stocks. Those who are owed money by the corporation cannot claim stockholders’ savings and other personal assets, even if the corporation goes into bankruptcy. Instead, the corporation is a separate legal entity, with the right to enter into contracts, to sue or be sued, and to continue to operate as long as it is profitable, which could be hundreds of years.
When the stockholders who own the corporation die, their stock is part of their estate and will be inherited by new owners. The corporation can go on doing business and usually will, unless the corporation is a small, closely held firm that is operated by one or two major stockholders. The largest
When a new corporation is formed, a legal document called a prospectus is prepared to describe what the business will do, as well as who the directors of the corporation and its major investors will be. Those who buy this initial stock offering become the first owners of the corporation, and their investments provide the funds that allow the corporation to begin doing business.
Separation of Ownership and Control
The advantages of limited liability and of an unlimited number of years to operate have made corporations the dominant form of business for large-scale enterprises in the
The top managers of a corporation are appointed or dismissed by a corporation’s board of directors, which represents stockholders’ interests. However, in practice, the board of directors is often made up of people who were nominated by the top managers of the company. Members of the board of directors are elected by a majority of voting stockholders, but most stockholders vote for the nominees recommended by the current board members. Stockholders can also vote by proxy—a process in which they authorize someone else, usually the current board, to decide how to vote for them.
There are, however, two strong forces that encourage the managers of a corporation to act in stockholders’ interests. One is competition. Direct competition from other firms that sell in the same markets forces a corporation’s managers to make sound business decisions if they want the business to remain competitive and profitable. The second is the threat that if the corporation does not use its resources efficiently, it will be taken over by a more efficient company that wants control of those resources. If a corporation becomes financially unsound or is taken over by a competing company, the top managers of the firm face the prospect of being replaced. As a result, corporate managers will often act in the best interests of a corporation’s stockholders in order to preserve their own jobs and incomes.
In practice, the most common way for a takeover to occur is for one company to purchase the stock of another company, or for the two companies to merge by legal agreement under some new management structure. Stock purchases are more common in what are called hostile takeovers, where the company that is being taken over is fighting to remain independent. Mergers are more common in friendly takeovers, where two companies mutually agree that it makes sense for the companies to combine. In 1996 there were over $556.3 billion worth of mergers and acquisitions in the
Takeovers by other firms became commonplace in the closing decades of the 20th century, and some research indicates that these takeovers made firms operate more efficiently and profitably. Those outcomes have been good news for shareholders and for consumers. In the long run, takeovers can help protect a firm’s workers, too, because their jobs will be more secure if the firm is operating efficiently. But initially takeovers often result in job losses, which force many workers to relocate, retrain, or in some cases retire sooner than they had planned. Such workforce reductions happen because if a firm was not operating efficiently, it was probably either operating in markets where it could not compete effectively, or it was using too many workers and other inputs to produce the goods and services it was selling. Sometimes corporate mergers can result in job losses because management combines and streamlines departments within the newly merged companies. Although this streamlining leads to greater efficiency, it often results in fewer jobs. In many cases, some workers are likely to be laid off and face a period of unemployment until they can find work with another firm.
How Corporations Raise Funds for Investment
By investing in new issues of a company’s stock, shareholders provide the funds for a company to begin new or expanded operations. However, most stock sales do not involve new issues of stock. Instead, when someone who owns stock decides to sell some or all of their shares, that stock is typically traded on one of the national stock exchanges, which are specialized markets for buying and selling stocks. In those transactions, the person who sells the stock—not the corporation whose stock is traded—receives the funds from that sale.
An existing corporation that wants to secure funds to expand its operations has three options. It can issue new shares of stock, using the process described earlier. That option will reduce the share of the business that current stockholders own, so a majority of the current stockholders have to approve the issue of new shares of stock. New issues are often approved because if the expansion proves to be profitable, the current stockholders are likely to benefit from higher stock prices and increased dividends. Dividends are corporate profits that some companies periodically pay out to shareholders.
The second way for a corporation to secure funds is by borrowing money from banks, from other financial institutions, or from individuals. To do this the corporation often issues bonds, which are legal obligations to repay the amount of money borrowed, plus interest, at a designated time. If a corporation goes out of business, it is legally required to pay off any bonds it has issued before any money is returned to stockholders. That means that stocks are riskier investments than bonds. On the other hand, all a bondholder will ever receive is the amount of money specified in the bond. Stockholders can enjoy much larger returns, if the corporation is profitable.
The final way for a corporation to pay for new investments is by reinvesting some of the profits it has earned. After paying taxes, profits are either paid out to stockholders as dividends or held as retained earnings to use in running and expanding the business. Those retained earnings come from the profits that belong to the stockholders, so reinvesting some of those profits increases the value of what the stockholders own and have risked in the business, which is known as stockholders’ equity. On the other hand, if the corporation incurs losses, the value of what the stockholders own in the business goes down, so stockholders’ equity decreases.
Entrepreneurs and Profits
Entrepreneurs raise money to invest in new enterprises that produce goods and services for consumers to buy—if consumers want these products more than other things they can buy. Entrepreneurs often make decisions on which businesses to pursue based on consumer demands. Making decisions to move resources into more profitable markets, and accepting the risk of losses if they make bad decisions—or fail to produce products that stand the test of competition—is the key role of entrepreneurs in the
Profits are the financial incentives that lead business owners to risk their resources making goods and services for consumers to buy. But there are no guarantees that consumers will pay prices high enough to cover a firm’s costs of production, so there is an inherent risk that a firm will lose money and not make profits. Even during good years for most businesses, about 70,000 businesses fail in the
Entrepreneurs invest money in firms with the expectation of making a profit. Therefore, if the profits a company earns are not high enough, entrepreneurs will not continue to invest in that firm. Instead, they will invest in other companies that they hope will be more profitable. Or if they want to reduce their risk, they can put their money into savings accounts where banks guarantee a minimum return. They can also invest in other kinds of financial securities (such as government or corporate bonds) that are riskier than savings accounts, but less risky than investments in most businesses. Generally, the riskier the investment, the higher the return investors will require to invest their money.
Calculating Profits
The dollar value of profits earned by
Accountants calculate profits by starting with the revenue a firm received from selling goods or services. The accountants then subtract the firm’s expenses for all of the material, labor, and other inputs used to produce the product. The resulting number is the dollar level of profits. To evaluate whether that figure is high or low, it must be compared to some measure of the size of the firm. Obviously, $1 million would be an incredibly large amount of profits for a very small firm, and not much profit at all for one of the largest corporations in the country, such as telecommunications giant AT&T Corp. or automobile manufacturer General Motors (GM).
To take into consideration the size of the firm, profits are calculated as a percentage of several different aspects of the business, including the firm’s level of sales, employment, and stockholders’ equity. Various individuals will use one of these different methods to evaluate a company’s performance, depending on what they want to know about how the firm operates. For example, an efficiency expert might examine the firm’s profits as a percentage of employment to determine how much profit is generated by the average worker in that firm. On the other hand, potential investors and a company’s chief executive would be more interested in profit as a percentage of stockholder equity, which allows them to gauge what kind of return to expect on their investments. A sales executive in the same firm might be more interested in learning about the company’s profit as a percentage of sales in order to compare its performance to the performances of competing firms in the same industry.
Using these different accounting methods often results in different profit percent figures for the same company. For example, suppose a firm earned a yearly profit of $1 million, with sales of $20 million. That represents a 5-percent rate of profit as a return on sales. But if stockholders’ equity in the corporation is $10 million, profits as a percent of stockholders’ equity will be 10 percent.
Return on Sales
Year after year,
Although it is true that on average, U.S. manufacturing firms only make about a 5-percent return on sales, that figure has little to do with the risks these businesses take. To see why, consider a specific example.
Most grocery stores earn a return on sales of only 1 to 2 percent, while some other kinds of firms typically earn more than the 5-percent average profit on sales. But selling more or less does not really increase what the owners of a grocery store (or most other businesses) are risking. Each time a grocery store sells $100 worth of canned spinach, it keeps about one or two dollars as profit, and uses the rest of the money to put more cans of spinach on the shelves for consumers to buy. At the end of the year, the grocery store may have sold thousands of dollars worth of canned spinach, but it never really risked those thousands of dollars. At any given time, it only risked what it spent for the cans that were at the store. When some cans were sold, the store bought new cans to put on the shelves, and it turned over its inventory of canned spinach many times during the year.
But the total value of these sales at the end of the year says little or nothing about the actual level of risk that the grocery store owners accepted at any point during the year. And in fact, the grocery industry is a relatively low-risk business, because people buy food in good times and bad. Providing goods or services where production or consumer demand is more variable—such as exploring for oil and uranium, or making movies and high fashion clothing—is far riskier.
Return on Equity
What stockholders risk—the amount they stand to lose if a business incurs losses and shuts down—is the money they have invested in the business, their equity. These are the funds stockholders provide for the firm whenever it offers a new issue of stock, or when the firm keeps some of the profits it earns to use in the businessas retained earnings, rather than paying those profits out to stockholders as dividends.
Profits as a return on stockholders’ equity for
At least part of any firm’s profits are required for it to continue to do business. Business owners could put their funds into savings accounts and earn a guaranteed level of return, or put them in government bonds that carry hardly any risk of default. If a business does not earn a rate of return in a particular market at least as high as a savings account or government bonds, its owners will decide to get out of that market and use the resources elsewhere—unless they expect higher levels of profits in the future.
Over time, high profits in some businesses or industries are a signal to other producers to put more resources into those markets. Low profits, or losses, are a signal to move resources out of a market into something that provides a better return for the level of risk involved. That is a key part of how markets work and respond to changing demand and supply conditions. Markets worked exactly that way in the
CAPITAL, SAVINGS, AND INVESTMENT
In the
Investments are one of the most important ways that economies are able to grow over time. Investments allow businesses to purchase factories, machines, and other capital goods, which in turn increase the production of goods and services and thus the standard of living of those who live in the economy. That is especially true when capital goods incorporate recently developed technologies that allow new goods and services to be produced, or existing goods and services to be produced more efficiently with fewer resources.
Investing in capital goods has a cost, however. For investment to take place, some resources that could have been used to produce goods and services for consumption today must be used, instead, to make the capital goods. People must save and reduce their current consumption to allow this investment to take place. In the
Interest rates are the price someone pays to borrow money. Savings institutions pay interest to people who deposit funds with the institution, and borrowers pay interest on their loans. Like any other price in a market economy, supply and demand determine the interest rate. The demand for money depends on how much money people and organizations want to have to meet their everyday expenses, how much they want to save to protect themselves against times when their income may fall or their expenses may rise, and how much they want to borrow to invest. The supply of money is largely controlled by a nation’s central bank—which in the
Providing Funds for Investments in Capital
To take advantage of specialization and economies of scale, firms must build large production facilities that can cost hundreds of millions of dollars. The firms that build these plants raise some funds with new issues of stock, as described above. But firms also borrow huge sums of money every year to undertake these capital investments. When they do that, they compete with government agencies that are borrowing money to finance construction projects and other public spending programs, and with households that are borrowing money to finance the purchase of housing, automobiles, and other goods and services.
Savings play an important role in the lending process. For any of this borrowing to take place, banks and other lenders must have funds to lend out. They obtain these funds from people or organizations that are willing to deposit money in accounts at the bank, including savings accounts. If everyone spent all of the income they earned each year, there would be no funds available for banks to lend out.
Among the three major sectors of the
Matching Borrowers and Lenders in Financial Markets
Households save money for several reasons: to provide a cushion against bad times, as when wage earners or others in the household become sick, injured, or disabled; to pay for large expenditures such as houses, cars, and vacations; to set aside money for retirement; or to invest. Banks and other financial institutions compete for households’ savings deposits by paying interest to the savers. Then banks lend those funds out to borrowers at a higher rate of interest than they pay to savers. The difference between the interest rates charged to borrowers and paid to savers is the main way that banks earn profits.
Of course banks must also be careful to lend the money to people and firms that are creditworthy—meaning they will be able to repay the loans. The creditworthiness of the borrower is one reason why some kinds of loans have higher rates of interest than others do. Short-term loans made to people or businesses with a long history of stable income and employment, and who have assets that can be pledged as collateral that will become the bank’s property if a loan is not repaid, will receive the lowest interest rates. For example, well-established firms such as AT&T often pay what is called the bank’s prime rate—the lowest available rate for business loans—when they borrow money. New, start-up companies pay higher rates because there is a greater risk they will default on the loan or even go out of business.
Other kinds of loans also have greater risks of default, so banks and other lenders charge different rates of interest. Mortgage loans are backed by the collateral of the property the loan was used to purchase. If someone does not pay his or her mortgage, the bank has the right to sell the property that was pledged as collateral and to collect the proceeds as payment for what it is owed. That means the bank’s risks are lower, so interest rates on these loans are typically lower, too. The money that is loaned to people who do not pay off the balances on their credit cards every month represents a greater risk to banks, because no collateral is provided. Because the bank does not hold any title to the consumer’s property for these loans, it charges a higher interest rate than it charges on mortgages. The higher rate allows the bank to collect enough money overall so that it can cover its losses when some of these riskier loans are not repaid.
If a bank makes too many loans that are not repaid, it will go out of business. The effects of bank failures on depositors and the overall economy can be very severe, especially if many banks fail at the same time and the deposits are not insured. In the

MONEY AND FINANCIAL MARKETS
A
Money and the Value of Money
Money is anything generally accepted as final payment for goods and services. Throughout history many things have been used around the world as money, including gold, silver, tobacco, cattle, and rare feathers or animal skins. In the
People can change the type of the money they hold by withdrawing funds from their checking account to receive currency or coins, or by depositing currency and coins in their checking accounts. But the money that people have in their checking accounts is really just the balance in that account, and most of those balances are never converted to currency or coins. Most people deposit their paychecks and then write checks to pay most of their bills. They only convert a small part of their pay to currency and coins. Strange as it seems, therefore, most money in the
Most people are surprised to learn that when banks make loans, the loans create new money in the economy. As we’ve seen, banks earn profits by lending out some of the money that people have deposited. A bank can make loans safely because on most days, the amount some customers are depositing in the bank is about the same amount that other customers are withdrawing. A bank with many customers holding a lot of deposits can lend out a lot of money and earn interest on those loans. But of course when that happens, the bank does not subtract the amount it has loaned out from the accounts of the people who deposited funds in savings and checking accounts. Instead, these depositors still have the money in their accounts, but now the people and firms to whom the bank has loaned money also have that money in their accounts to spend. That means the total amount of money in the economy has increased. This process is called fractional reserve banking, because after making loans the bank retains only a fraction of its deposits as reserves. The bank really could not pay all of its depositors without calling in the loans it has made. It also means that money is created when banks make loans but destroyed when loans are paid off.
At one time the dollar, like most other national currencies, was backed by a specified quantity of gold or silver held by the federal government. At that time, people could redeem their dollars for gold or silver. But in practice paper currency is much easier to carry around than large amounts of gold or silver. Therefore, most people have preferred to hold paper money or checking balances, as long as paper currency and checks are accepted as payment for goods and services and maintain their value in terms of the amount of goods and services they can buy.
Eventually governments around the world also found it expensive to hold and guard large quantities of gold or silver. As foreign trade grew, governments found it especially difficult to transfer gold and silver to other countries that decided to redeem paper money acquired through international trade. They, too, changed to using paper currencies and writing checks against deposits in accounts. In 1971 the
The real value of the dollar today depends only on the amount of goods and services a dollar can purchase. That purchasing power depends primarily on the relationship between the number of dollars people are holding as currency and in their checking and savings accounts, and the quantity of goods and services that are produced in the economy each year. If the number of dollars increases much more rapidly than the quantity of goods and services produced each year, or if people start spending the dollars they hold more rapidly, the result is likely to be inflation. Inflation is an increase in the average price of all goods and services. In other words, it is a decrease in the value of what each dollar can buy.
The Federal Reserve System and Monetary Policy
Governments often attempt to reduce inflation by controlling the supply of money. Consequently, organizations that control how much money is issued in an economy play a major role in how the economy performs, in terms of prices, output and employment levels, and economic growth. In the
There are 12 regional Federal Reserve banks. These banks are not commercial banks. They do not accept savings deposits from or provide loans to individuals or businesses. Instead, the Federal Reserve functions as a central bank for other banks and for the federal government. In that role the Federal Reserve System performs several important functions in the national economy. First, the branches of the Federal Reserve distribute paper currency in their regions. Dollar bills are actually Federal Reserve notes. You can look at a dollar bill of any denomination and see the number for the regional Federal Reserve Bank where the bill was originally issued. But of course the dollar is a national currency, so a bill issued by any regional Federal Reserve Bank is good anyplace in the country. The distribution of currency occurs as commercial banks convert some of their reserve balances at the Federal Reserve System into currency, and then provide that currency to bank depositors who decide to hold some of their money balances as currency rather than deposits in checking accounts. The U.S. Treasury prints new currency for the Federal Reserve System. The bills are introduced into circulation when commercial banks use their reserves to buy currency from the Federal Reserve Bank.
Second, the regional Federal Reserve banks transfer funds for checks that are deposited by a bank in one part of the country, but were written by someone who has a checking account with a bank in another part of the country. Millions of checks are processed this way every business day. Third, the regional Federal Reserve Banks collect and analyze data on the economic performance of their regions, and provide that information and their analysis of it to the national Federal Reserve System. Each of the 12 regions served by the Federal Reserve banks has its own economic characteristics. Some of these regional economies are concerned more with agricultural issues than others; some with different types of manufacturing and industries; some with international trade; and some with financial markets and firms. After reviewing the reports from all different parts of the country, the national Federal Reserve System then adopts policies that have major effects on the entire
By far the most important function of the Federal Reserve System is controlling the nation’s money supply and the overall availability of credit in the economy. If the Federal Reserve System wants to put more money in the economy, it does not ask the Treasury to print more dollar bills. Remember, much more money is held in checking and savings accounts than as currency, and it is through those deposit accounts that the Federal Reserve System most directly controls the money supply. The Federal Reserve affects deposit accounts in one of three ways.
First, it can allow banks to hold a smaller percentage of their deposits as reserves at the Federal Reserve System. A lower reserve requirement allows banks to make more loans and earn more money from the interest paid on those loans. Banks making more loans increase the money supply. Conversely, a higher reserve requirement reduces the amount of loans banks can make, which reduces or tightens the money supply.
The second way the Federal Reserve System can put more money into the economy is by lowering the rate it charges banks when they borrow money from the Federal Reserve System. This particular interest rate is known as the discount rate. When the discount rate goes down, it is more likely that banks will borrow money from the Federal Reserve System, to cover their reserve requirements and support more loans to borrowers. Once again, those loans will increase the nation’s money supply. Therefore, a decrease in the discount rate can increase the money supply, while an increase in the discount rate can decrease the money supply.
In practice, however, banks rarely borrow money from the Federal Reserve, so changes in the discount rate are more important as a signal of whether the Federal Reserve wants to increase or decrease the money supply. For example, raising the discount rate may alert banks that the Federal Reserve might take other actions, such as increasing the reserve requirement. That signal can lead banks to reduce the amount of loans they are making.
The third way the Federal Reserve System can adjust the supply of money and the availability of credit in the economy is through its open market operations—the buying or selling of government bonds. Open market operations are actually the tool that the Federal Reserve uses most often to change the money supply. These open-market operations take place in the market for government securities. The
Government bonds are not money, because they are not generally accepted as final payment for goods and services. (Just try paying for a hamburger with a government savings bond.) But when the Federal Reserve System pays for a federal government bond with a check, that check is new money—specifically, it represents a loan to the government. This loan creates a higher balance in the government’s own checking account after the funds have been transferred from the privately owned Federal Reserve Bank to the government. That new money is put into the economy as soon as the government spends the funds. On the other hand, if the Federal Reserve sells government bonds, it collects money that is taken out of circulation, since the bonds that the Federal Reserve sells to banks, firms, or households cannot be used as money until they are redeemed at a later date.
The Wall Street Journal and other financial media regularly report on purchases of bonds made by the Federal Reserve and other buyers at auctions of
To summarize the Federal Reserve System’s tools of monetary policy: It can increase the supply of money and the availability of credit by lowering the percentage of deposits that banks must hold as reserves at the Federal Reserve System, by lowering the discount rate, or by purchasing government bonds through open market operations. The Federal Reserve System can decrease the supply of money and the availability of credit by raising reserve ratios, raising the discount rate, or by selling government bonds.
The Federal Reserve System increases the money supply when it wants to encourage more spending in the economy, and especially when it is concerned about high levels of unemployment. Increasing the money supply usually decreases interest rates—which are the price of money paid by those who borrow funds to those who save and lend them. Lower interest rates encourage more investment spending by businesses, and more spending by households for houses, automobiles, and other “big ticket” items that are often financed by borrowing money. That additional spending increases national levels of production, employment, and income. However, the Federal Reserve Bank must be very careful when increasing the money supply. If it does so when the economy is already operating close to full employment, the additional spending will increase only prices, not output and employment.
Effect of Monetary Policies on the
The monetary policies adopted by the Federal Reserve System can have dramatic effects on the national economy and, in particular, on financial markets. Most directly, of course, when the Federal Reserve System increases the money supply and expands the availability of credit, then the interest rate, which determines the amount of money that borrowers pay for loans, is likely to decrease. Lower interest rates, in turn, will encourage businesses to borrow more money to invest in capital goods, and will stimulate households to borrow more money to purchase housing, automobiles, and other goods.
But the Federal Reserve System can go too far in expanding the money supply. If the supply of money and credit grows much faster than the production of goods and services in the economy, then prices will increase, and the rate of inflation will rise. Inflation is a serious problem for those who live on fixed incomes, since the income of those individuals remains constant while the amount of goods and services they can purchase with their income decreases. Inflation may also hurt banks and other financial institutions that lend money, as well as savers. In a period of unanticipated inflation, as the value of money decreases in terms of what it will purchase, loans are repaid with dollars that are worth less. The funds that people have saved are worth less, too.
When banks and savers anticipate higher inflation, they will try to protect themselves by demanding higher interest rates on loans and savings accounts. This will be especially true on long-term loans and savings deposits, if the higher inflation is considered likely to continue for many years. But higher interest rates create problems for borrowers and those who want to invest in capital goods.
If the supply of money and credit grows too slowly, however, then interest rates are again likely to rise, leading to decreased spending for capital investments and consumer durable goods (products designed for long-term use, such as television sets, refrigerators, and personal computers). Such decreased spending will hurt many businesses and may lead to a recession, an economic slowdown in which the national output of goods and services falls. When that happens, wages and salaries paid to individual workers will fall or grow more slowly, and some workers will be laid off, facing possibly long periods of unemployment.
For all of these reasons, bankers and other financial experts watch the Federal Reserve’s actions with monetary policy very closely. There are regular reports in the media about policy changes made by the Federal Reserve System, and even about statements made by Federal Reserve officials that may indicate that the Federal Reserve is going to change the supply of money and interest rates. The chairman of the Federal Reserve System is widely considered to be one of the most influential people in the world because what the Federal Reserve does so dramatically affects the
LABOR AND LABOR MARKETS
Labor includes work done for employers and work done in a person’s own household, but labor markets deal only with work that is done for some form of financial compensation. Labor markets include all the means by which workers find jobs and by which employers locate workers to staff their businesses. A number of factors influence labor and labor markets in the

Labor Supply and Demand
The wages and salaries that
Workers seeking higher wages often learn skills that will increase the likelihood of finding a higher-paying job. The knowledge, skills, and experience a worker has acquired are the worker’s human capital. Education and training can clearly increase workers’ human capital and productivity, which makes them more valuable to employers. In general, more educated individuals make more money at their jobs. However, a greater level of education does not always guarantee higher wages. Certain professions that demand a high level of education, such as teaching elementary and secondary school, are not high-paying. Such situations arise when the number of people with the training to do that job is relatively large compared with the number of people that employers want to hire. Of course this situation can change over time if, for example, fewer young people choose to train for the profession.
Supply and demand factors change in labor markets, just as they do in markets for goods and services. As a result, occupations that paid high wages and salaries in the past sometimes become outdated, while entirely new occupations are created as a result of technological change or changes in the goods and services consumers demand. For example, blacksmiths were once among the most skilled workers in the
The process of creative destruction carries over from product markets to labor markets because the demand for particular goods and services creates a demand for the labor to produce them. Conversely, when the demand for particular goods or services decreases, the demand for labor to produce them will also fall. Similarly, when new technologies create new products or new ways of producing existing products, some workers will have new job opportunities, but other workers might have to retrain, relocate, or take new jobs.
Factors Affecting Labor Markets
Changes in society and in the makeup of the population also affect labor markets. For example, starting in the 1960s it became more common for married women to work outside the home. Unprecedented numbers of women—many with little previous job experience and training—entered the labor markets for the first time during the 1970s. As a result, wages for entry-level jobs were pushed down and did not rise as rapidly as they had in the past. This decline in entry-level wages was further fueled by huge numbers of teens who were also entering the labor market for the first time. These young people were the children of the baby boom of 1946 to 1964, a period in which the birth rate increased dramatically in the
The baby boomers’ effects have continued to reverberate through the
By the 1990s, the women and baby boomers who first entered the job market in the 1970s had acquired more experience and training. Therefore, the aging of the labor force was not affecting entry-level jobs as it once did, and starting salaries for college graduates were rising rapidly again. There will be, however, other kinds of labor market and public policy issues to face when the baby boomers begin to retire in the early decades of the 21st century.
Immigration

Generally, immigration raises national output and income levels. These changes occur because immigration increases the number of workers in the economy, which allows employers to produce more goods and services. Capital resources in the economy may also become more valuable as immigration increases. The number of workers available to work with machines and tools increases, as does the number of consumers who want to buy goods and services.However, wages for jobs that are filled by large numbers of immigrants may decrease. This wage decline stems from greater competition for these jobs and from the fact that many immigrants are willing to work for lower wages than other

Discrimination
Women and many minorities have long faced discrimination in
Analysis of wage discrimination against black Americans leads to similar conclusions. Specifically, after controlling for differences in age, education, hours worked, experience, occupation, and region of the country, wages for black men are roughly 10 percent lower than for white men, though occupational segregation appears to be less common by race than by gender. Issues other than wage discrimination are also important to note for black workers. In particular, unemployment rates for black workers are about twice as high as they are for white workers. Partly because of that, a much lower percentage of the
Hispanic workers generally receive wages about 5 percent lower than white workers, after adjusting for differences in education, training, experience, and other characteristics that affect workers’ productivity. Some studies suggest that differences in the ability to speak English are particularly important in understanding wage differences for Hispanic workers.
The differences between the earnings of white males and earnings of females and minorities slowly decreased in the closing decades of the 20th century. Some laws and regulations prohibiting discrimination seem to have helped in this process. A large part of those gains occurred shortly after the adoption of the 1964 Civil Rights Act, which among other things, outlawed discrimination by employers and unions. Many economists worry that the discrimination that remains may be more difficult to identify and eliminate through legislation.
Discrimination in competitive labor markets is economically inefficient as well as unfair. When workers are not paid based on the value of what they add to employers’ production and profit levels, society loses opportunities to use labor resources in their most valuable ways. As a result, fewer goods and services are produced. If employers discriminate against certain groups of workers, they will pay for that behavior in competitive markets by earning lower profits. Similarly, if workers refuse to work with (or for) coworkers of a different gender, race, or ethnic background, they will have to accept lower wages in competitive markets because their discrimination makes it more costly for employers to run their businesses. And if customers refuse to be served by workers of a certain gender, race, or ethnicity in certain kinds of jobs, they will have to pay higher prices in competitive markets because their discrimination raises the costs of providing these goods and services.
Those who are discriminated against receive lower wages and often experience other forms of economic hardship, such as more frequent and longer periods of unemployment. Beyond that, the lower wage rates and restricted career opportunities they face will naturally affect their decisions about how much education and training to acquire and what kinds of careers to pursue. For that reason, some of the costs of discrimination are paid over very long periods of time, sometimes for a worker’s entire life.
It is clear that there is still discrimination in the

The different focus by
Most of these craft unions were members of the American Federation of Labor (AFL), founded in 1886. The strong bargaining position of these skilled workers, and the fact that these workers typically earned much higher wages than most other workers, led the AFL unions to focus on wages and other financial benefits for their members. Samuel Gompers, the president of the AFL for nearly all of its first 38 years, once summarized his philosophy of unions by saying, “What do we want? More. When do we want it? Now.”
By contrast, industrial unions—which represent all of the workers at a firm or work site, regardless of their function or trade—were generally not successful in the
After the Wagner Act was passed, the number of workers who belonged to unions increased rapidly. This trend continued through World War II (1939-1945), when unions successfully negotiated more fringe benefits for their members. These fringe benefits were partly a result of wage and price controls established during the war, which made large wage increases impossible. In the 1950s union strength continued to grow, and the national association of industrial unions, known as the Congress of Industrial Organization (CIO) merged with the AFL.
Since the late 1970s, total union membership has fallen. The percentage of the
Union membership has also declined as the government established laws and regulations that mandate for all workers many of the benefits and guarantees that unions had achieved for their members. These mandates include minimum wage, workplace safety, higher pay rates for overtime, and oversight of the management of pension funds if employers fund or partially fund pensions.
Third, many U.S. firms have become more aggressive in opposing the recognition of unions as bargaining agents for their employees, and in dealing with confrontations involving existing unions. For example, it is increasingly common for firms to hire permanent replacement workers if strikes occur at a firm or work site.
Finally, workers with college degrees held a larger percentage of jobs in the
Unions, however, continue to play many valuable roles in representing their members on economic issues. Equally or perhaps more importantly, unions provide workers with a stronger voice in how work is done and how workers are treated. This is particularly true in jobs where it is difficult to identify clearly how much an individual worker contributes to total output in the production process. During the 1990s, many
Unemployment
A persistent problem for the
Frictional unemployment occurs as a result of labor mobility, when workers change jobs or wait to begin a new job. Labor mobility is, in general, a good thing for workers and the economy overall. It allows workers to look for the best available job for which they are qualified and lets employers find the best-qualified people for their job openings. Because this searching and matching by employees and employers takes time, on any given day in a market economy there will be some workers who are looking for a new job, or waiting to begin a job. Even when economists describe the economy as being at full employment there will be some frictional unemployment (as much as 5 to 6 percent of the labor force in some years). This kind of unemployment is generally not a major economic problem.
Cyclical unemployment occurs when the economy goes into a recession. The basic causes of cyclical unemployment are decreases in the levels of consumption, investment, or government spending in the economy, or a decrease in the demand for goods and services exported to other countries. As national spending and production levels fall, some employers begin to lay off workers. Cyclical unemployment varies greatly according to the health of the economy. Some of the highest unemployment rates for the last decades of the 20th century took place during the recession of 1982 to 1983, when unemployment levels reached almost 10 percent. The highest

Most policies designed to reduce structural unemployment provide training programs for these workers, or subsidize education and training programs available from colleges and universities, technical schools, or businesses. In some cases, the government provides support for retraining when increased competition from imported goods and services puts

GOVERNMENT AND THE ECONOMY
Although the market system in the
In addition, government programs regulate safety in products and in the workplace, provide national defense, and provide public assistance to some members of society coping with economic hardship. There are some products that must be provided to households and firms by the government because they cannot be produced profitably by private firms. For example, the government funds the construction of interstate highways, and operates vaccination programs to maintain public health. Local governments operate public elementary and secondary schools to ensure that as many children as possible will receive an education, even when their parents are unable to afford private schools.
Other kinds of goods and services (such as health care and higher education) are produced and consumed in private markets, but the government attempts to increase the amount of these products available in the economy. For yet other goods and services, the government acts to decrease the amount produced and consumed; these include alcohol, tobacco, and products that create high levels of pollution. These special cases where markets fail to produce the right amount of certain goods and services mean that the government has a large and important role to play in adjusting some production patterns in the
At the most basic level, the government makes it possible for markets to function more efficiently by clearly defining and enforcing people’s property or ownership rights to resources and by providing a stable currency and a central banking system (the Federal Reserve System in the

In other cases, the government allows private markets to operate, but regulates them. For example, the government makes laws and regulations concerning product safety. Some of these laws and regulations prohibit the use of highly flammable material in the manufacture of children’s clothing. Other regulations call for government inspection of food products, and still others require extensive government review and approval of potential prescription drugs.
In still other situations, the government determines that private markets result in too much production and consumption of some goods, such as alcohol, tobacco, and products that contribute to environmental pollution. The government is also concerned when markets provide too little of other products, such as vaccinations that prevent contagious diseases. The government can use its spending and taxing authority to change the level of production and consumption of these products, for example, by subsidizing vaccinations.
Even the staunchest supporters of private markets have recognized a role for the government to provide a safety net of support for

Correcting Market Failures
The government attempts to adjust the production and consumption of particular goods and services where private markets fail to produce efficient levels of output for those products. The two major examples of these market failures are what economists call public goods and external benefits or costs.
Providing Public Goods
Private markets do not provide some essential goods and services, such as national defense. Because national defense is so important to the nation’s existence, the government steps in and entirely funds and administers this product.
Public goods differ from private goods in two key respects. First, a public good can be used by one person without reducing the amount available for others to use. This is known as shared consumption. An example of a public good that has this characteristic is a spraying or fogging program to kill mosquitoes. The spraying reduces the number of mosquitoes for all of the people who live in an area, not just for one person or family. The opposite occurs in the consumption of private goods. When one person consumes a private good, other people cannot use the product. This is known as rival consumption. A good example of rival consumption is a hamburger. If someone else eats the sandwich, you cannot.
The second key characteristic of public goods is called the nonexclusion principle: It is not possible to prevent people from using a public good, regardless of whether they have paid for it. For example, a visitor to a town who does not pay taxes in that community will still benefit from the town’s mosquito-spraying program. With private goods, like a hamburger, when you pay for the hamburger, you get to eat it or decide who does. Someone who does not pay does not get the hamburger.
Because many people can benefit from the same pubic goods and share in their consumption, and because those who do not pay for these goods still get to use them, it is usually impossible to produce these goods in private markets. Or at least it is impossible to produce enough in private markets to reach the efficient level of output. That happens because some people will try to consume the goods without paying for them, and get a free ride from those who do pay. As a result, the government must usually take over the decision about how much of these products to produce. In some cases, the government actually produces the good; in other cases it pays private firms to make these products.
The classic example of a public good is national defense. It is not a rival consumption product, since protecting one person from an invading army or missile attack does not reduce the amount of protection provided to others in the country. The nonexclusion principle also applies to national defense. It is not possible to protect only the people who pay for national defense while letting bombs or bullets hit those who do not pay. Instead, the government imposes broad-based taxes to pay for national defense and other public goods.
Adjusting for External Costs or Benefits
There are some private markets in which goods and services are produced, but too much or too little is produced. Whether too much or too little is produced depends on whether the problem is one of external costs or external benefits. In either case, the government can try to correct these market failures, to get the right amount of the good or service produced.
External costs occur when not all of the costs involved in the production or consumption of a product are paid by the producers and consumers of that product. Instead, some of the costs shift to others. One example is drunken driving. The consumption of too much alcohol can result in traffic accidents that hurt or kill people who are neither producers nor consumers of alcoholic products. Another example is pollution. If a factory dumps some of its wastes in a river, then people and businesses downstream will have to pay to clean up the water or they may become ill from using the water.
When people other than producers and consumers pay some of the costs of producing or consuming a product, those external costs have no effect on the product’s market price or production level. As a result, too much of the product is produced considering the overall social costs. To correct this situation, the government may tax or fine the producers or consumers of such products to force them to cover these external costs. If that can be done correctly, less of the product will be produced and consumed.
An external benefit occurs when people other than producers and consumers enjoy some of the benefits of the production and consumption of the product. One example of this situation is vaccinations against contagious diseases. The company that sells the vaccine and the individuals who receive the vaccine are better off, but so are other people who are less likely to be infected by those who have received the vaccine. Many people also argue that education provides external benefits to the nation as a whole, in the form of lower unemployment, poverty, and crime rates, and by providing more equality of opportunity to all families.
When people other than the producers and consumers receive some of the benefits of producing or consuming a product, those external benefits are not reflected in the market price and production cost of the product. Because producers do not receive higher sales or profits based on these external benefits, their production and price levels will be too low–based only on those who buy and consume their product. To correct this, the government may subsidize producers or consumers of these products and thus encourage more production.
Maintaining Competition
Competitive markets are efficient ways to allocate goods and services while maintaining freedom of choice for consumers, workers, and entrepreneurs. If markets are not competitive, however, much of that freedom and efficiency can be lost. One threat to competition in the market is a firm with monopoly power. Monopoly power occurs when one producer, or a small group of producers, controls a large part of the production of some product. If there are no competitors in the market, a monopoly can artificially drive up the price for its products, which means that consumers will pay more for these products and buy less of them. One of the most famous cases of monopoly power in
Largely in reaction to the business practices of Standard Oil and other trusts or monopolistic firms, the
The government does allow what economists call natural monopolies. However, the government then regulates those businesses to protect consumers from high prices and poor service, and often limits the profits these firms can earn. The classic examples of natural monopolies are local services provided by public utilities. Economies of scale make it inefficient to have even two companies distributing electricity, gas, water, or local telephone service to consumers. It would be very expensive to have even two sets of electric and telephone wires, and two sets of water, gas, and sewer pipes going to every house. That is why firms that provide these services are called natural monopolies.
There have been some famous antitrust cases in which large companies were broken up into smaller firms. One such example is the breakup of American Telephone and Telegraph (AT&T) in 1982, which led to the formation of a number of long-distance and regional telephone companies. Other examples include a ruling in 1911 by the Supreme Court of the
Some government policies intentionally reduce competition, at least for some period of time. For example, patents on new products and copyrights on books and movies give one producer the exclusive right to sell or license the distribution of a product for 17 or more years. These exclusive rights provide the incentive for firms and individuals to spend the time and money required to develop new products. They know that no one else will copy and sell their product when it is introduced into the marketplace, so it pays to devote more resources to developing these new products.
The benefits of certain other government policies that reduce competition are not always this clear, however. More controversial examples include policies that restrict the number of taxicabs in a large city or that limit the number of companies providing cable television services in a community. It is much less expensive for cable companies to install and operate a cable television system than it is for large utilities, such as the electric and telephone companies, to install the infrastructure they need to provide services. Therefore, it is often more feasible to have two or more cable companies in reasonably large cities. There are also more substitutes for cable television, such as satellite dish systems and broadcast television. But despite these differences, many cities auction off cable television rights to a single company because the city receives more revenue that way. Such a policy results in local monopolies for cable television, even in areas where more competition might well be possible and more efficient.
Establishing government policies that efficiently regulate markets is difficult to do. Policies must often balance the benefits of having more firms competing in an industry against the possible gains from allowing a smaller number of firms to compete when those firms can achieve economies of scale. The government must try to weigh the benefits of such regulations against the advantages offered by more competitive, less regulated markets.
Promoting Full Employment and Price Stability
In addition to the monetary policies of the Federal Reserve System, the federal government can also use its taxing and spending policies, or fiscal policies, to counteract inflation or the cyclical unemployment that results from too much or too little total spending in the economy. Specifically, if inflation is too high because consumers, businesses, and the government are trying to buy more goods and services than it is possible to produce at that time, the government can reduce total spending in the economy by reducing its own spending. Or the government can raise taxes on households and businesses to reduce the amount of money the private sector spends. Either of these fiscal policies will help reduce inflation. Conversely, if inflation is low but unemployment rates are too high, the government can increase its spending or reduce taxes on households and businesses. These policies increase total spending in the economy, encouraging more production and employment.
Some government spending and tax policies work in ways that automatically stabilize the economy. For example, if the economy is moving into a recession, with falling prices and higher unemployment, income taxes paid by individuals and businesses will automatically fall, while spending for unemployment compensation and other kinds of assistance programs to low-income families will automatically rise. Just the opposite happens as the economy recovers and unemployment falls—income taxes rise and government spending for unemployment benefits falls. In both cases, tax programs and government-spending programs change automatically and help offset changes in nongovernment employment and spending.
In some cases, the federal government uses discretionary fiscal policies in addition to automatic stabilization policies. Discretionary fiscal policies encompass those changes in government spending and taxation that are made as a result of deliberations by the legislative and executive branches of government. Like the automatic stabilization policies, discretionary fiscal policy can reduce unemployment by increasing government spending or reducing taxes to encourage the creation of new jobs. Conversely, it can reduce inflation by decreasing government spending and raising taxes. .
In general, the federal government tries to consider the condition of the national economy in its annual budgeting deliberations. However, discretionary spending is difficult to put into practice unless the nation is in a particularly severe episode of unemployment or inflation. In such periods, the severity of the situation builds more consensus about what should be done, and makes it more likely that the problem will still be there to deal with by the time the changes in government spending or tax programs take effect. But in general, it takes time for discretionary fiscal policy to work effectively, because the economic problem to be addressed must first be recognized, then agreement must be reached about how to change spending and tax levels. After that, it takes more time for the changes in spending or taxes to have an effect on the economy.
When there is only moderate inflation or unemployment, it becomes harder to reach agreement about the need for the government to change spending or taxes. Part of the problem is this: In order to increase or decrease the overall level of government spending or taxes, specific expenditures or taxes have to be increased or decreased, meaning that specific programs and voters are directly affected. Choosing which programs and voters to help or hurt often becomes a highly controversial political issue.
Because discretionary fiscal policies affect the government’s annual deficit or surplus, as well as the national debt, they can often be controversial and politically sensitive. For these reasons, at the close of the 20th century, which experienced years with normal levels of unemployment and inflation, there was more reliance on monetary policies, rather than on discretionary fiscal policies to try to stabilize the national economy. There have been, however, some famous episodes of changing federal spending and tax policies to reduce unemployment and fight inflation in the
Limitations of Government Programs
Government economic programs are not always successful in correcting market failures. Just as markets fail to produce the right amount of certain kinds of goods and services, the government will often spend too much on some programs and too little on others for a number of reasons. One is simply that the government is expected to deal with some of the most difficult problems facing the economy, taking over where markets fail because consumers or producers are not providing clear signals about what they want. This lack of clear signals also makes it difficult for the government to determine a policy that will correct the problem.
Political influences, rather than purely economic factors, often play a major role in inefficient government policies. Elected officials generally try to respond to the wishes of the voting public when making decisions that affect the economy. However, many citizens choose not to vote at all, so it is not clear how good the political signals are that elected officials have to work with. In addition, most voters are not well informed on complicated matters of economic policy.
For example, the federal government’s budget director David Stockman and other officials in the administration of President Reagan proposed cuts in income tax rates. Congress adopted the cuts in 1981 and 1984 as a way to reduce unemployment and make the economy grow so much that tax revenues would actually end up rising, not falling. Most economists and many politicians did not believe that would happen, but the tax cuts were politically popular.
In fact, the tax cuts resulted in very large budget deficits because the government did not collect enough taxes to cover its expenditures. The government had to borrow money, and the national debt grew very rapidly for many years. As the government borrowed large sums of money, the increased demand caused interest rates to rise. The higher interest rates made it more expensive for
In addition, whenever resources are allocated through the political process, the problem of special interest groups looms large. Many policies, such as tariffs or quotas on imported goods, create very large benefits for a small group of people and firms, while the costs are spread out across a large number of people. That gives those who receive the benefits strong reasons to lobby for the policy, while those who each pay a small part of the cost are unlikely to oppose it actively. This situation can occur even if the overall costs of the program greatly exceed its overall benefits.
For instance, the
For sugar growers and refiners, of course, the higher price of sugar and the greater quantity of sugar they can produce and sell makes the import barriers something they value greatly. It is clearly in their interest to hire lobbyists and write letters to elected officials supporting these programs. When these officials hear from the people who benefit from the policies, but not from those who bear the costs, they may well decide to vote for the import restrictions. This can happen despite the fact that many studies indicate the total costs to consumers and the
Special interest groups and issues are facts of life in the political arena. One striking way to see that is to drive around the

Actually, government spending has increased since the 1930s for a number of specific reasons. First, the different branches of government began to provide services that improved the economic security of individuals and families. These services include Social Security and Medicare for the elderly, as well as health care, food stamps, and subsidized housing programs for low-income families. In addition, new technology increased the cost of some government services; for example, sophisticated new weapons boosted the cost of national defense. As the economy grew, so did demand for the government to provide more and better transportation services, such as super highways and modern airports. As the population increased and became more prosperous, demand grew for government-financed universities, museums, parks, and arts programs. In other words, as incomes rose in the

IX IMPACT OF THE WORLD ECONOMY Today, virtually every country in the world is affected by what happens in other countries. Some of these effects are a result of political events, such as the overthrow of one government in favor of another. But a great deal of the interdependence among the nations is economic in nature, based on the production and trading of goods and services.
One of the most rapidly growing and changing sectors of the U.S. economy involves trade with other nations. In recent decades, the level of goods and services imported from other countries by U.S. consumers, businesses, and government agencies has increased dramatically. But so, too, has the level of U.S. goods and services sold as exports to consumers, businesses, and government agencies in other nations. This international trade and the policies that encourage or restrict the growth of imports and exports have wide-ranging effects on the U.S. economy.
As the nation with the world’s largest economy, the United States plays a key role on the international political and economic stages. The
All over the world, people specialize in producing particular goods and services, then trade with others to get all of the other goods and services they can afford to buy and consume. It is far more efficient for some people to be lawyers and other people doctors, butchers, bakers, and teachers than it is for each person to try to make or do all of the things he or she consumes.
In earlier centuries, the majority of trade took place between individuals living in the same town or city. Later, as transportation and communications networks improved, individuals began to trade more frequently with people in other places. The industrial revolution that began in the 18th century greatly increased the volume of goods that could be shipped to other cities and regions, and eventually to other nations. As people became more prosperous, they also traveled more to other countries and began to demand the new products they encountered during their travels.
The basic motivation and benefits of international trade are actually no different from those that lead to trade within a nation. But international trade differs from trade within a nation in two major ways. First, international trade involves at least two national currencies, which must usually be exchanged before goods and services can be imported or exported. Second, nations sometimes impose barriers on international trade that they do not impose on trade that occurs entirely inside their own country.
A U.S. Imports and Exports
U.S. exports are goods and services made in the
Most of this trade occurs between industrialized, developed nations and involves similar kinds of products as both imports and exports. While it is true that the U.S. imports some things that are only found or grown in other parts of the world, most trade involves products that could be made in the United States or any other industrialized market economies. In fact, some products that are now imported, such as clothing and textiles, were once manufactured extensively in the United States. However, economists note that just because things were or could be made in a country does not mean that they should be made there.
Just as individuals can increase their standard of living by specializing in the production of the things they do best, nations also specialize in the products they can make most efficiently. The kinds of goods and services that the United States can produce most competitively for export are determined by its resources. The United States has a great deal of fertile land, is the most technologically advanced nation in the world, and has a highly educated and skilled labor force. That explains why
Many other nations have lower labor costs than the
Greater specialization allows producers to take full advantage of economies of scale. Manufacturers can build large factories geared toward production of specialized inventories, rather than spending extra resources on factory equipment needed to produce a wide variety of goods. Also, by selling more of their products to a greater number of consumers in global markets, manufacturers can produce enough to make specialization profitable.
The
B Barriers to Trade Despite the mutual advantages of global trade, governments often adopt policies that reduce or eliminate international trade in some markets. Historically, the most important trade barriers have been tariffs (taxes on imports) and quotas (limits on the number of products that can be imported into a country). In recent decades, however, many countries have used product safety standards or legal standards controlling the production or distribution of goods and services to make it difficult for foreign businesses to sell in their markets. For example,
While there are special reasons for limiting imports or exports of certain kinds of products—such as products that are vital to a nation’s national defense—economists generally view trade barriers as hurting both importing and exporting nations. Although the trade barriers protect workers and firms in industries competing with foreign firms, the costs of this protection to consumers and other businesses are typically much higher than the benefits to the protected workers and firms. And in the long run it usually becomes prohibitively expensive to continue this kind of protection. Instead it often makes more sense to end the trade barrier and help workers in industries that are hurt by the increased imports to relocate or retrain for jobs with firms that are competitive. In the
During recessions, when national unemployment rates are high or rising, workers and firms facing competition from foreign companies usually want the government to adopt trade barriers to protect their industries. But again, historical experience with such policies shows that they do not work. Perhaps the most famous example of these policies occurred during the Great Depression of the 1930s. The

X CURRENT TRENDS AND ISSUES
In the early decades of the 21st century, many different social, economic and technological changes in the
Over the next century, average standards of living in the United States will almost certainly rise, so that on average, people living at the end of the century are likely to be better off in material terms than people are today. During the past century, the primary reasons for the increase in living standards in the United States were technological progress, business investments in capital goods, and people’s investments in greater education and training (which were often subsidized by government programs). There is no evident reason why these same factors will not continue to be the most important reasons underlying changes in the standard of living in the United States and other industrialized economies. A comparatively small number of economists and scientists from other fields argue that limited supplies of energy or of other natural resources will eventually slow or stop economic growth. Most, however, expect those limits to be offset by discoveries of new deposits or new types of resources, by other technological breakthroughs, and by greater substitution of other products for the increasingly scarce resources.
Although the U.S. economy will likely remain the world’s largest national economy for many decades, it is far less certain that U.S. households will continue to enjoy the highest average standard of living among industrialized nations. A number of other nations have rapidly caught up to U.S. levels of income and per capita output over the last five decades of the 20th century. They did this partly by adopting technologies and business practices that were first developed in the United States, or by developing their own technological and managerial innovations. But in large part, these nations have caught up with the United States because of their higher rates of savings and investment, and in some cases, because of their stronger systems for elementary and secondary education and for training of workers.
Most U.S. workers and families will still be better off as the U.S. economy grows, even if some other economies are growing faster and becoming somewhat more prosperous, as measured per capita. Certainly families in Britain today are far better off materially than they were 150 to 200 years ago, when Britain was the largest and wealthiest economy in the world, despite the fact that many other nations have since surpassed the British economy in size and affluence.
A more important problem for the U.S. economy in the next few decades is the unequal distribution of gains from growth in the economy. In recent decades, the wealth created by economic growth has not been as evenly distributed as was the wealth created in earlier periods. Incomes for highly educated and trained workers have risen faster than average, while incomes for workers with low levels of education and training have not increased and have even fallen for some groups of workers, after adjusting for inflation. Other industrialized market economies have also experienced rising disparity between high-income and low-income families, but wages of low-income workers have not actually fallen in real terms in those countries as they have in the
In most industrialized nations, the demand for highly educated and trained workers has risen sharply in recent decades. That happened in part because many kinds of jobs now require higher skill levels, but other factors were also important. New production methods require workers to frequently and rapidly change what they do on the job. They also increase the need for quality products and customer service and the ability of employees to work in teams. Increased levels of competition, including competition from foreign producers, have put a higher premium on producing high quality products.
Several other factors help explain why the relative position of low-income workers has fallen more in the United States than in other industrialized Western nations. The growth of college graduates has slowed in the

A few economists have called for radical changes in the Social Security system to deal with these problems. One suggestion has been to allow workers to save and invest in private retirement accounts rather than pay into Social Security. Thus far, those approaches have not been considered politically feasible or equitable. Current retirees strongly oppose changing the system, as do people who fear that they will lose future benefits from a program they have paid taxes to support all their working lives. Others worry that private accounts will not provide adequate retirement income for low-income workers, or that the government will still be called on to support those who make bad investment choices in their private retirement accounts.

Greater world trade and cooperation offer an enormous range of mutually beneficial activities. Trading with other countries inevitably increases opportunities for travel and cultural exchange, as well as business opportunities. In a very broad sense, nations that buy and sell goods and services with each other also have a greater stake in other forms of peaceful cooperation, and in seeing other countries prosper and grow.
On the other hand, global interdependence also raises major problems—political, economic, and environmental—that require international solutions. Many of these problems, such as pollution, global warming, and assistance for developing nations, have been controversial even when solutions were discussed only at the national level. Often, controversy increases with the number of nations that must agree on a solution, but some problems require global remedies. Such problems will challenge the productive capacity of the

The United States contains some of the best cropland in the world. Cultivated farmland constitutes 19 percent of the land area of the country and makes the
The United States is the largest producer of corn, soybeans, and sorghum, and it ranks second in the production of wheat, oats, citrus fruits, and tobacco. The United States is also a major producer of sugar cane, potatoes, peanuts, and beet sugar. It ranks fourth in the world in cattle production and second in hogs. The total annual value of farm output increased from $55 billion in 1970 to $202 billion in 1996. Farmers in the United States not only produce enough food to feed the nation’s population, they also export more farm products than any other nation. Despite this vast output, the U.S. economy is so large and diversified that agriculture accounted for only 2 percent of annual GDP and employed only 3 percent of the workforce in 1998.
During the 20th century, many Americans moved from rural to urban areas of the United States, resulting in large population decreases in farming regions. Even though the number of farms has been declining since the 1930s, overall production has increased because of more efficient operations. Bigger farms, operated as large businesses, have increasingly replaced small family farms. The owners of larger farms make greater use of modern machinery and other equipment. By the 1990s, farm operations were highly mechanized. By applying mechanization, technology, efficient business practices, and scientific advances in agricultural methods, larger farms produce great quantities of agricultural output using small amounts of labor and land.
In 1999 there were 2,194,070 farms in the United States, down from a high of 6.8 million in 1935. As smaller farms have been consolidated into larger units, the average farm size in the United States increased from about 63 hectares (about 155 acres) to 175 hectares (432 acres) by 1999.
Cattle production is widespread throughout the United States. Texas leads in the production of range cattle, which are allowed to graze freely. Iowa and Illinois are important for nonrange feeder cattle, which are cattle that eat feed grain provided by cattle farmers. The Dairy Belt continues to be concentrated in southern Wisconsin but is also prominent in the rural landscapes of most northeastern states and fairly common in other states, too. Hog production tends to be concentrated in Iowa, Illinois, and surrounding states, where hogs are fattened for market. Chicken production is widespread, but southern states, including Texas, Arkansas, and Alabama, dominate.

B Manufacturing and Energy Sector B1 Manufacturing
The United States leads all nations in the value of its yearly manufacturing output. Manufacturing employs about one-sixth of the nation’s workers and accounts for 17 percent of annual GDP. In 1996 the total value added by manufacturing was $1.8 trillion. Value added is the price of finished goods minus the cost of the materials used to make them. Although manufacturing remains a key component of the

B1b Principal Products
Ranked by value added by manufacturing, in 1996 the leading categories of U.S. manufactured goods were chemicals, industrial machinery, electronic equipment, processed foods, and transportation equipment. The chemical industry accounted for about 11.1 percent of the overall annual value added by manufacturing.Texas Louisiana
Industrial machinery accounted for 10.7 percent of the yearly value added by manufacture. Industrial machinery includes engines, farm equipment, various kinds of construction machinery, computers, and refrigeration equipment.California Illinois Ohio Michigan
Factories in theUnited States United States San Francisco Boston Chapel Hill , and Durham North Carolina Austin , Texas United States Seattle , Washington Boston , Massachusetts San Francisco , California
Food processing accounted for about 10.2 percent of the overall annual value added by manufacturing. Food processing is an important industry in several states noted for the production of food crops and livestock, or both. California has a large fruit- and vegetable-processing industry. Meat-packing is important to agriculture in Illinois and dairy processing is a large industry in Wisconsin.
Transportation equipment includes passenger cars, trucks, airplanes, space vehicles, ships and boats, and railroad equipment. This category accounted for 10.1 percent of the yearly value added by manufacturing. Michigan, with its huge automobile industry, is a leading producer of transportation equipment.
The manufacture of fabricated metal and primary metal is concentrated in the nation’s industrial core region. Iron ore from the Lake Superior district, plus that imported from Canada and other countries, and Appalachian coal are the basis for a large iron and steel industry. Pennsylvania, Ohio, Indiana, Illinois, and Michigan are leading states in the value of primary metal output. The fabricated metal industry, which includes the manufacture of cans and other containers, hardware, and metal forgings and stampings, is important in the same states. The primary metals industry of these states provides the basic raw materials, especially steel, that are used in making metal products.
Printing and publishing is a widespread industry, with newspapers published throughout the country. New York, with its book-publishing industry, is the leading state, but California, Illinois, and Pennsylvania also have sizable printing and publishing industries.
The manufacture of paper products is important in several states, particularly those with large timber resources, especially softwood trees used to make most paper. The manufacture of paper and paperboard contributes significantly to the economies of Wisconsin, Alabama, Georgia, Washington, New York, Maine, and Pennsylvania.
Other major U.S. manufactures include textiles, clothing, precision instruments, lumber, furniture, tobacco products, leather goods, and stone, clay, and glass items.
B2 Energy Production
The energy to power the nation's economy—to provide fuels for its vehicles and furnaces and electricity for its machinery and appliances—is derived primarily from petroleum, natural gas, and coal. Measured in terms of heat-producing capacity (British thermal units, or Btu), petroleum provides 39 percent of the total energy consumed in theUnited States
Natural gas is the source of 24 percent of the energy consumed. Many industrial plants use natural gas for heat and power, and several million households burn it for heating and cooking. Coal provides 22 percent of the energy consumed. Its major uses are in the generation of electricity, which uses more than three-fourths of all the coal consumed, and in the manufacture of steel.
Waterpower generates 4 to 5 percent of the nation’s energy, and nuclear power supplies about 10 percent. Both are employed mainly to produce electricity for residential and industrial use. Nuclear energy has been viewed as an important alternative to expensive petroleum and natural gas, but its development has proceeded somewhat more slowly than originally anticipated. People are reluctant to live near nuclear plants for fear of a radiation-releasing accident. Another obstacle to the expansion of nuclear power use is that it is very expensive to dispose of radioactive material used to power the plants. These nuclear fuel materials remain radioactive for thousands of years and pose health risks if they are not properly contained.

Natural gas accounts for 9 percent of the electricity produced, and refined petroleum for 2 percent. The states producing the most electricity from natural gas areTexas California Florida New York Massachusetts Washington , Oregon New York California Illinois Pennsylvania South Carolina California
Petroleum is a key resource for an American lifestyle based on extensive use of private automobiles and trucks for commerce and businesses. Since 1947, when theUnited States
In 1970 domestic crude-oil production reached a record high of 3.5 billion barrels, but this had to be supplemented by imports amounting to 12 percent of the nation’s overall crude oil supply. Most Americans were unaware of the dependence of the country on foreign petroleum until an oil embargo imposed by some Middle Eastern nations in 1973 and 1974 led to government price ceilings for gasoline and other energy products, which in turn led to shortages. In 1973 the nation imported about one-fourth of its total supply of crude oil. Imports continued to rise until 1977, when about half of the crude and refined oil supply was imported. Imports then declined for a time, largely because energy-conservation measures were introduced and because other domestic energy sources such as coal were used increasingly. As of 1997, however, 47 percent of the crude oil needs of theUnited States

By far the largest sector of the economy in terms of output and employment is the service and commerce sector. This sector grew rapidly during the last part of the 20th century, creating many new jobs and more than offsetting the slight loss of jobs in manufacturing industries. In 1998 commerce and service industries generated 72 percent of the GDP and employed 75 percent of theU.S.

During the early decades of the 20th century, motor vehicle transport developed as a serious competitor of the railroads, both for passengers and freight. Federal aid to states for highway construction began with the passage of the Federal-Aid Road Act of 1916.
The federal aid program was greatly expanded in 1956 when the government began an ambitious expansion of the Interstate Highway System, a 74,165-km (46,084-mi) network of limited-access highways that connects the nation’s principal cities. This carefully designed system enables motorists to drive across the country without encountering an intersection or traffic signal. It carries about 20 percent ofU.S. U.S.
Air transport began to compete with other modes of transport in theUnited States United States
By the end of the 20th century, large and small airports across the nation formed a network providing air transportation to individual travelers. The nation had 5,129 public and 13,263 private airports in 1996. The largest airports in theUnited States William B. Hartsfield International Airport Atlanta , Georgia Illinois Dallas-Fort Worth Airport Texas Los Angeles International Airport California
The United States has a relatively small commercial shipping fleet. In 1998 only 473 vessels of 1,000 gross tons and larger were registered in the United States. Only 56 percent were in use; most of the remainder formed part of a government-owned military reserve fleet. However, many American ship owners register their vessels in foreign countries such as Liberia and Panama, where crew wages, taxes, and operating costs are lower.
In terms of the number of ships docking, New Orleans, Louisiana, is the busiest port in the nation; each year it handles more than 6,000 vessels. Other leading ports include Los Angeles-Long Beach, California; Houston, Texas; New York, New York; San Francisco-Oakland, California; Miami, Florida; and Philadelphia, Pennsylvania. Crude petroleum accounts for 22 percent of the waterborne tonnage of the United States. Petroleum products make up 18 percent. Coal accounts for 14 percent, and farm products for 14 percent.
The inland waterway network of theUnited States Mississippi River system, the Great Lakes , and the coastal waterways. Some 66 percent of the annual water freight traffic is on the Mississippi River and its tributaries, 17 percent is on the Great Lakes , and most of the remainder is on the coastal waterways. A major thoroughfare of the coastal waterways is the Intracoastal Waterway , a navigable, toll-free shipping route extending for about 1,740 km (about 1,080 mi) along the Atlantic Coast Gulf of Mexico coast. About 45 percent of the total annual traffic on all coastal waterways travels on the Gulf Intracoastal Waterway , about 30 percent is on the Atlantic Intracoastal Waterway , and about 25 percent is on Pacific Coast

Other mass publications with vast audiences included the weekly TV Guide, reaching 13.2 million readers, and the monthly Reader’s Digest, with a circulation of 15.1 million copies.
D2 Technology
One of the most far-reaching technological advances of the late 20th century took place in the field of computer science. Computers developed from large, cumbersome, and expensive machines to relatively small and affordable devices. The development of the personal computer (PC) in the 1970s made it possible for many individuals to own computers and allowed even small businesses to use computer technology in their operations. The U.S. Bureau of the Census estimates that jobs in the computer industry are growing at the fastest rate of any employment area, with job openings for computer specialists expected to double from 1996 to 2006.
The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the U.S. military. Originally limited to researchers at a handful of universities and government facilities, the Internet quickly became a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 million U.S. citizens had access to the Internet at home or work. More and more Americans were paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet.
