p>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 United States, Britain, and other market economies helped many new businesses to grow by building systems of canals (such as the Erie
Canal) during the mid-19th century. But then the canal systems were replaced or “destroyed” by the railroads, which in turn saw their role diminished with the rise of national systems of highways and airports.
The same thing happened in the communications industry in the United
States. The Pony Express, which carried mail between Missouri and
California in the early 1860s, went out of business with the completion of telegraph lines to California. In the 20th century, the telegraph was replaced by the telephone. Time and time again, one decade’s innovation is partially replaced or even destroyed by the next round of technological change.

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 U.S. economy. Sometimes these changes are triggered by something as simple as weather conditions someplace else in the world that affect the production of grain, coffee, sugar, or other crops. Sometimes it reflects political or financial upheavals in Europe,
Asia, or other parts of the world. There have been several examples of such events in the U.S. economy in the 1990s. Higher coffee prices occurred after poor harvests of coffee beans in South America, and U.S. banks lost large sums of money following financial and political crises in places such as Indonesia and Russia.

The ability to respond quickly to an increasingly volatile economic and political environment is, in many ways, one of the greatest strengths of the U.S. economic system. But these changes can result in hardships for some people or even some large segments of the economy. For example, importing clothing produced in other nations has benefited U.S. consumers by keeping clothing prices lower. In addition, it has been profitable for the firms that import and sell this clothing. However, it has also reduced the number of jobs available in clothing manufacturing for U.S. workers.

Many people think the most important general issue facing the U.S. economy today is how to balance the benefits of quickly adapting to changing economic conditions against the costs of abandoning the old ways. It is vital for the economy to adapt quickly to changing conditions and to focus on producing goods and services that will meet the most recent demands of the market place. However, when businesses close because their products no longer meet the demands of the market, it is important to make retraining or new jobs available to workers who lost their means of making a living.

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 United States and other market economies, privately owned firms produce most goods and services using a variety of techniques. One of the most important is specialization, in which different firms make different kinds of products and individual workers perform specific jobs within a company.

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 United States also operate under one of three different legal forms: corporations, partnerships, or sole proprietorships. Each of these forms has certain advantages and disadvantages. Because of that, these three types of business organizations often operate in different kinds of markets. For example, most firms with large amounts of money invested in factories and equipment are organized as corporations.

Specialization and the Division of Labor

In earlier centuries, especially in frontier areas, families in the
United States were much more self-sufficient, producing for themselves most of the goods and services they consumed. But as the U.S. population and economy grew, it became easier for people to buy more and more things in the marketplace. Once that happened, people faced a choice they still face today: In terms of time, money, and other things that they could do, is it less expensive to make something themselves or to let someone else produce it and buy it from them?

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 United States and all other industrialized economies. When businesses specialize, they focus on providing a particular product or type of product. For instance, some large companies produce only automobiles and trucks, or even special parts of cars and trucks, such as tires.

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 United States and other industrialized nations. This trend is especially prevalent in the manufacturing sector.
For example, many automobile factories produce thousands of cars each day, and some shipyards employ more than 10,000 workers. One open-pit mine in the western United States has dug a crater so large that it can be seen from space.

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 United States and throughout the world. By selling worldwide, companies in the United
States and in other countries can reach many more customers.
Specialization is ultimately limited by the size of the market for a good or service. In other words, larger markets always allow for greater levels of specialization. For example, in small towns with few customers to serve, there is often only one clothing store that carries a small selection of many different kinds of clothing. In large cities with a million or more potential customers, there are much larger clothing stores with many more choices of items and styles, and even some stores that sell only hats, gloves, or some other particular kind of clothing.

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 Japan and sent to the United States, large pickups and four-wheel drive sport utility vehicles are often exported from the United States to Japan and other nations. Similarly, the United
States exports large commercial passenger jets to most countries, but imports many small jets from Canada, Brazil, and other nations. While this may seem strange at first glance, it allows greater specialization in production for particular kinds of products.

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 United
States during the 20th century. First, most employment shifted from farming in rural areas to industrial jobs in cities and suburbs. Then, during the second half of the century, production and employment patterns changed again as a result of technological advances, increased levels of world trade, and a rapid increase in the demand for services.

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 U.S. economy came with the nation’s growing prosperity in the years following World War II (1939-1945). This prosperity resulted in a population with more money to spend on services and leisure activities. More people began dining out at restaurants, taking vacations to far-off locations, and going to movies and other forms of entertainment. As family incomes increased, a wealthier population became more willing to pay others for services.

As a result of these developments, the closing decades of the 20th century saw a dramatic increase in service industries in the United
States. In 1940 about 33 percent of U.S. employees worked in manufacturing, and about 49 percent worked in service-producing industries. By the late 1990s, only 26 percent worked in goods-producing industries, and 74 percent worked in service-producing industries. This change was driven by powerful market forces, including technological change and increased levels of world trade, competition, and income.

Some observers worried that this growth of employment in service- producing industries would result in declining living standards for most
U.S. workers, but in fact most of this growth has occurred in industries where job skill requirements and wages have risen or at least remained high. That is less surprising when you consider that this employment includes business and repair services, entertainment and recreation occupations, and professional and related services (including health care, education, and legal services). United States consumers and families are, on average, financially better off today than they were 50 or 100 years ago, and they have more leisure time, which is one of the reasons why the demand for services has increased so rapidly.

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 United States has changed from predominantly agriculture to manufacturing to services, individuals, firms, and communities have faced often-difficult adjustments. Many workers lost jobs in traditional occupations and had to seek employment in jobs that required completely different sets of skills. Standards of living declined in some communities whose economies centered on farming or around large factories that shut down. In recent decades, populations have decreased in some states where agriculture provides a significant number of jobs. While high-technology industries in places such as
California's Silicon Valley were booming and attracting larger populations, some textile and clothing factories in Southern and Midwest states were closing their doors.

Public Policies to “Protect” Firms and Workers

Historically in the United States, the government has rarely stepped in to protect individual businesses from changing levels of demand or competition. There have been some notable exceptions, including the federal government’s guarantee of $1.5 billion in loans to the Chrysler
Corporation, the nation’s third-largest automobile manufacturer, when it faced bankruptcy in 1980.

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 U.S. businesses and workers.
