7. Specialization and International Trade Чижов

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.
