Abstract
Alternative explanations for the formation of U.S. foreign economic policy are explored using the acrimonious but inconclusive conflict between the United States and its largest South American ally over Brazil's restrictive policies toward the computer industry. After comparing a post-dependency/bargaining perspective, the theory of hegemonic stability, and Stephen Krasner's structural conflict model, the article argues that systemic perspectives on foreign economic policy must be complemented by an account of the interaction between the effects of international position and the dynamics of domestic politics. The resulting politicized state-centric approach, which integrates interest-based politics and ideologically defined state aims, is proposed as a means of more fully understanding the dilemmas of a declining hegemon.
