Economic impacts of social influence in mechanism design and game theory

本课题从理性动机和行为动机的观点出发，对博弈论、信息经济学、机制设计进行了研究。在真实的情境和实验研究中，我们经常可以观察到经济主体从纯粹的自利出发而表现出不一致的行为。在这些情况下，我们有时可以发现可预测的行为模式。澄清这些行为模式并提供与之相适应的理论模型是非常重要的。基于这些背景，本项目研究了与经济主体的行为方面相关的各种重要研究领域，例如具有社会影响力的行为实施，行为噪声交易者的泡沫和崩溃，不确定R&D投资的讨价还价，互惠动机的长期关系。

This project investigated game theory, informational economics, and mechanism design from the viewpoint of rational and behavioral motives. In real situations and experimental studies, we can often observe that the economic agents behave in the inconsistent manner from the pure self-interest. In these situations, we can sometimes find out behavioral patterns that are predictable. it is quite important to clarify these behavioral patterns and provide theoretical models that are compatible with the behavioral patterns. Based on these backgrounds, this projects studies various important research fields that are relevant to the behavioral aspects of economic agents, such as behavioral implementation with social influence, bubbles and crashes with behavioral noise traders, bargaining with uncertain R&D investments, long-term relationship with reciprocal motives.
