Take a minute and look around. You might be surprised to discover how many of the everyday items in your life are made overseas. Your shirt might be made in China. Perhaps your stereo was assembled in Japan. The watch you're wearing could be from Switzerland. And yes, the shoes that you are sporting might have been assembled in the United States.

It is so common to find items produced worldwide that people rarely even think about it. Not too long ago, countries consumed goods predominately produced within their borders. As transportation has become increasingly less expensive and telecommunications have improved, international trade has flourished.

In general, international trade allows countries to focus on the industries in which they can be most productive and efficient. In this way, trade often raises the standard of living of both producers and consumers. International trade also has a dark side.
