United States (Economy)

INTRODUCTION
United States (Economy), all of the ways goods and services are produced, distributed, and consumed by individuals and businesses in the United States. The U.S. economy is immense. In 1998 it included more than 270 million consumers and 20 million businesses. U.S. consumers purchased more than $5.5 trillion of goods and services annually, and businesses invested over a trillion dollars more for factories and equipment. Over 80 percent of the goods and services purchased by U.S. consumers each year are made in the United States; the rest are imported from other nations. In addition to spending by private households and businesses, government agencies at all levels (federal, state, and local) spend roughly an additional $1.5 trillion a year. In total, the annual value of all goods and services produced in the United States, known as the Gross Domestic Product (GDP), was $9.25 trillion in 1999.

Those levels of production, consumption, and spending make the U.S. economy by far the largest economy the world has ever known—despite the fact that some other nations have far more people, land, or other resources. Through most of the 20th century, U.S. citizens also enjoyed the highest material standards of living in the world. Some nations have higher per capita (per person) incomes than the United States. However, these comparisons are based on international exchange rates, which set the value of a country’s currency based on a narrow range of goods and services traded between nations. Most economists agree that the United States has a higher per capita income based on the total value of goods and services that households consume. American prosperity has attracted worldwide attention and imitation. There are several key reasons why the U.S. economy has been so successful and other reasons why, in the 21st century, it is possible that some other industrialized nations will surpass the U.S. standard of living. To understand those historical and possible future events, it is important first to understand what an economic system is and how that system affects the way people make decisions about buying, selling, spending, saving, investing, working, and taking time for leisure activities.

This article consists of ten major sections. The first section of this article discusses how individual people, business and labor organizations, and social institutions make up the U.S. economic system. Next, the article discusses the production of goods and services. The third section describes the different types of businesses that operate in the United States, such as proprietorships, partnerships, and corporations. It also discusses how entrepreneurs acquire and organize the funding and resources needed to run a business.

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 U.S. economy, because most people earn their incomes by working for wages and salaries. By the same token, for most firms, labor is the most costly input used in producing the things the firms sell.

The role of government in the U.S. economy is the subject of section seven. The government performs a number of economic roles that private markets cannot provide. It also offers some public services that elected officials believe will be in the best interests of the public. The relationship between the U.S. economy and the world economy is discussed in section eight. Section nine looks at current trends and issues that the U.S economy faces at the start of the 21st century. The final section provides an overview of the kinds of goods and services produced in the United States.

This is one of seven major articles that together provide a comprehensive discussion of the United States of America. For more information on the United States, please see the other six major articles: United States (Overview), United States (Geography), United States (People), United States (Culture), United States (Government), and United States (History).

U.S. ECONOMIC SYSTEM

An economic system refers to the laws and institutions in a nation that determine who owns economic resources, how people buy and sell those resources, and how the production process makes use of resources in providing goods and services. The U.S. economy is made up of individual people, business and labor organizations, and social institutions. People have many different economic roles—they function as consumers, workers, savers, and investors. In the United States, people also vote on public policies and for the political leaders who set policies that have major economic effects. Some of the most important organizations in the U.S. economy are businesses that produce and distribute goods and services to consumers. Labor unions, which represent some workers in collective bargaining with employers, are another important kind of economic organization. So, too, are cooperatives—organizations formed by producers or consumers who band together to share resources—as well as a wide range of nonprofit organizations, including many charities and educational organizations, that provide services to families or groups with special problems or interests.

For the most part, the United States has a market economy in which individual producers and consumers determine the kinds of goods and services produced and the prices of those products. The most basic economic institution in market economies is the system of markets in which goods and services are bought and sold. That is where consumers buy most of the food, clothing, and shelter they use, and any number of things that they simply want to have or that they enjoy doing. Private businesses make and sell most of those goods and services. These markets work by bringing together buyers and sellers who establish market prices and output levels for thousands of different goods and services.

A guiding principle of the U.S. economy, dating back to the colonial period, has been that individuals own the goods and services they make for themselves or purchase to consume. Individuals and private businesses also control the factors of production. They own buildings and equipment, and are free to hire workers, and acquire things that businesses use to produce goods and services. Individuals also own the businesses that are established in the United States. In other economic systems, some or all of the factors of production are owned communally or by the government.

For the most part, U.S. producers decide which goods and services to make and offer to sell, and what prices to charge for those products. Goods are tangible things—things you can touch—that satisfy wants. Examples of goods are cars, clothing, food, houses, and toys. Services are activities that people do for themselves or for other people to satisfy their wants. Examples of services are cutting hair, polishing shoes, teaching school, and providing police or fire protection.

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 United States does not have a pure market economy, and the government plays an important role in the national economy. It provides services and goods that the market cannot provide effectively, such as national defense, assistance programs for low-income families, and interstate highways and airports. The government also provides incentives to encourage the production and consumption of certain types of products, and discourage the production and consumption of others. It sets general guidelines for doing business and makes policy decisions that affect the economy as a whole. The government also establishes safety guidelines that regulate consumer products, working conditions, and environmental protection.

Factors of Production

The factors of production, which in the United States are controlled by individuals, fall into four major categories: natural resources, labor, capital, and entrepreneurship.

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 United States has many natural resources. They include vast areas of fertile land for growing crops, extensive coastlines with many natural harbors, and several large navigable rivers and lakes on which large ships and barges carry products to and from most regions of the nation. The United States has a generally moderate climate, and an incredible diversity of landscapes, plants, and wildlife.

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 United States in 1998, nearly 138 million adults were working or actively looking for work. This is the nation's labor force, which includes those who work for wages and salaries and those who file government tax forms for income earned through self-employment. It does not include homemakers or others who perform unpaid labor in the home, such as raising, caring for, and educating children; preparing meals and maintaining the home; and caring for family members who are ill. Nor, of course, does it count those who do not report income to avoid paying taxes, in some cases because their work involves illegal activities.

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 United States in the late 1990s is estimated to be more than $11 trillion. Roughly half of that is equipment and the other half buildings or other structures. Businesses have additional capital investments in their inventories of finished products, raw materials, and partially completed goods.

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 Midwest. This same firm may also hire many kinds of workers. It may find some of its newly hired workers by recruiting recent graduates of high schools, colleges, or technical schools. But its market for labor may also include older workers who have decided to move to a new area, or to find a new job and employer where they currently live.

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.

Markets and the Problem of Scarcity

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 U.S. economy as much as any other.

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 U.S. economy, with its system of private ownership, has an extensive set of markets for final products and for the factors of production. The economy has been particularly successful in providing material goods and services to most of its citizens. That is even more striking when results in the U.S. economy are compared with those of other nations and economic systems. Nevertheless, most U.S. consumers say they would like to be able to buy and use more goods and services than they have today. And some U.S. citizens are calling for significant changes in how the economic system works, or at least in how the purchasing power and the goods and services in the system are divided up among different individuals and families.

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 markets are not confined to specific 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 United States for many other kinds of goods and services to be sold this way. For instance, many people today use the Internet—the worldwide computer-based network of information systems—to buy airline tickets, make hotel reservations, and rent a car for their vacation. Other people buy and sell items ranging from books, clothing, and airline tickets to baseball cards and other rare collectibles over the Internet. Although these Internet buyers and sellers may never meet face to face the way buyers and sellers do in more traditional markets, these markets share certain basic features.

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.

System of Markets

System of Markets for All Goods and Services
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 U.S. economy to operate with great efficiency and a high degree of freedom for consumers and producers.

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 U.S. city on any given day. Individual sellers decide how many sandwiches they are likely to sell and arrange to have enough meat and bread available to meet the demand from their customers.

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 U.S. market economy has made these adjustments very quickly, even compared with other market economies in Western Europe, Canada, and Japan.

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).

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 United States, incomes have risen substantially over the past 200 years. As that happened, the demand for most goods and services also increased. There are, however, a few products that people buy less of as income falls. Examples of these inferior goods include low quality foods and fabrics.

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.
