"Complexity and Nonlinear Economic Systems : Theory and Application"

我们邀请了在经济学、物理学、生物学、数学和工程学前沿领域工作的科学家，在东京举办了一场关于复杂性科学的跨学科研讨会。去年，我们在京都和东京举办了四次关于经济动力学、博弈论、计量经济学和经济理论的国际会议。在宏观经济动力学研究组，我们定期召开研讨会，西村与维也纳大学的Engelbert Dockner、纽约大学的Jess Benhabib和康奈尔大学的Tapan Mitra合作。西村还应邀参加了几次国际会议，并发表了主题演讲。西村在日本发表了超越Chikumashobo的复杂性和Springer的优化和混沌。他还编辑了《日本经济评论》、《经济理论杂志》、《差分方程式杂志》和《…》的特刊在区域经济学方面，我们发展了“新空间经济学”的理论框架。藤田的这两本教科书是世界范围内空间经济学研究生课程中使用最广泛的。此外，通过定期举办空间经济学研讨会，我所已成为新空间经济学的国际中心。博弈论研究组将复杂经济系统视为战略相互依存，并分析其动力机制的基本性质。主要研究课题包括人类决策、认知与有限理性、合作、组织形成、进化与学习、拍卖与谈判实验、全球变暖问题的国际机制设计。非线性计量经济学小组发展了统计方法并阐明了其理论性质。可以预期，他们将为分析经验性的全球环境数据和城市经济数据做出贡献。较少

We held an interdisciplinary symposium on the Science of Complexity in Tokyo by inviting scientists who work in the frontier of economics, physics, biology, mathematics and engineering. They gave talks on the researches in the Complexity and three out of our group also presented their papers.In the last year we held four international conferences on economic dynamics, game theory, econometrics and economic theory in Kyoto and Tokyo.In the research group of macro economic dynamics we regularly meet for workshops, and Nishimura collaborates with Engelbert Dockner (University of Vienna), Jess Benhabib (New York University) and Tapan Mitra (Cornell University).Also Nishimura was invited to several international conferences and gave keynote addresses.Nishimura published in Japan Beyond the complexity from Chikumashobo and Optimization and Chaos from Springer. And also he edited special issues in the Japanese Economic Review, Journal of Economic Theory and Journal of Difference Equation and … More Applications.In regional economics, we have developed the theoretical framework for "the new spatial econmics." The two text books by Fujita are the most widely used in the graduate courses for the spatial economics world-wide. Moreover, by regularly sponsoring workshops in the spatial economics, our institute has become an international center of the new spatial economics.Game Theory Research Group considers complex economic systems as strategic interdependencies and analyses fundamental properties of their dynamic mechanisms. Main research topics include human decision-making, cognition and bounded rationality, cooperation, organization formation, evolution and learning, experiments of auctions and negotiations, international mechanism design in global warming problems.Nonlinear econometrics group developed the statistical methodologies and clarified their theoretical properties. They can be expected to contribute to analyze empirical global environmental data and urban economics data. Less
