[Excerpt] Today’s global economy, or what many call globalization, has a growing impact on the economic futures of American companies, workers, and families. Increasing integration with the world economy makes the U.S. and other economies more productive. For most Americans, this has translated into absolute increases in living standards and real disposable incomes. However, while the U.S. economy as a whole benefits from globalization, it is not always a win-win situation for all Americans. Rising trade with low-wage developing countries not only increases concerns of job loss, but it also leads U.S. workers to fear that employers will lower their wages and benefits in order to compete. Globalization facilitated by the information technology revolution expands international trade in a wider range of services, but also subjects an increasing number of U.S. white collar jobs to outsourcing and international competition. Also, globalization may benefit some groups more than others, leading some to wonder whether the global economy is structured to help the few or the many.
The current wave of globalization is supported by three broad trends. The first is technology, which has sharply reduced the cost of communication and transportation that previously divided markets. The second is a dramatic increase in the world supply of labor engaged in international trade. The third is government policies that have reduced barriers to trade and investment. Whether these trends are creating new vulnerabilities for workers is the subject of increasing research and debate.
