The purpose of this research is to study the nature of optimal labor contracts in Japan. We focus on the role of the disparity of economic power among cities and generations as a key determinant of existing labor contracts. Our results obtained in this project include the following : (1) We studied the role of covenants not to compete and the governmental regulation of them, and shown that the government sometimes faces a tradeoff relationship between ex ante efficient employer-employee matching and ex post efficient allocation of talent among firms. (2) We studied the driving force of formation, integration, and fragmentation of labor unions in Japanese firms, and shown that the preference diversity within a generation is the most important key to explain them.
