| Research Abstract |
In this research, we attempted to construct new analytical frameworks to examine desirable social institutions as well as environments, such as organizational forms, social customs and global environments, in an economic system using game theory and dynamic economic system theory.
1. We undertook a game theoretic research to examine decentralized resource allocation under different social institutions and environment so that we can design a desirable institutions and environments. In particular, we analyzed significance and effects of introducing lotteries in implementing social decision function in decentralized manner, tradeoffs between liberty and efficiency in restricting strategy sets of each individual within a society. We also showed, using evolutionary game theory approach with bounded rational players, the importance of the role of custom in inducting coordination among players, and, using experimental game theory, the role of social norms in human decision making.
2. We analyzed how the extent of authority delegations, wage structure and promotion system within an organization affect the degree of cooperation and information exchange among employees, and characterized the Japanese organizational structure compared with those in other countries.
3. We characterized the desirable properties of carbon tax, in view of dynamic efficiency as well as international equity, as a measure against global warming. We also analyzed the mechanism of how the business cycle diffuses dynamically and internationally using non-linear dynamics, and examined how asymmetric information affects macro-economic behavior through investment using monopolistic competition models.
