Abstract
The economic theory of international trade has changed dramatically over the last decade by admitting into its mainstream a body of literature that focuses on the implications of monopolistic and oligopolistic elements in international markets. By applying the tools of the “new” industrial organization in an international context, two new classes of models have emerged: models of intra-industry trade and models of strategic trade policy. The policy implications of models of strategic trade policy were quite disturbing for the economics profession, since these models demonstrated that the classical harmony between national and cosmopolitan welfare maximization does not exist if one assumes opportunities for strategic manipulation of oligopolistic international industries. This article reviews two prominent models of strategic trade policy—the Brander-Spencer model and the Krugman model—and relates them to more familiar earlier concepts, such as Stackelberg's asymmetrical duopoly solution and the venerable infant-industry argument for government intervention. The primary purpose of this article, however, is to provide a synopsis of the large literature addressing the question of whether models of strategic trade policy can give guidance for government policy.
