Negishi's contributions to the development of economic analysis: Research programs and outcomes

This paper surveys Negishi's significant contributions to economics and the research programs they have generated. In a series of papers and books, Negishi developed a number of models and methods of analysis that changed the course of modern economics and catalyzed research in areas that range from welfare and theoretical to applied and computable general equilibrium analysis, and the extension of imperfect competition to general equilibrium. trade theory and international economics. This paper shows that the Negishian research programs that emanated from his works are progressive, and still have an ongoing impact on mainstream economic analysis decades after their publication.
