Problem
1. Is the existence of product differentiation a necessary condition for the existence of intra-industry trade? Why or why not?
2. Is the distinction between "intra-industry trade" and "interindustry trade" a useful distinction? Why or why not?
3. In recent years, U.S. firms have become very concerned about the increasing production of "pirated" and "counterfeit" goods abroad, especially in Asia. Successful U.S. export products are copied by foreign producers without payment of royalties and/or adherence to patent or copyright protection. How might this phenomenon affect the product cycle and new product research and development in the United States?
