Theory and Applications of Repeated Games

我访问耶鲁的主要目的是扩展我对关系契约和无限重复博弈的基础理论的研究。在与Susanne Ohlendorf合著的论文《具有侧支付的抗再谈判关系契约》中，我们刻画了在行为完全可观察、侧支付可能存在以及关系契约具有抗再谈判性的假设下，双方通过关系契约所能获得的收益集。我们对文献的贡献是为一般框架开发一种简单的方法来确定任何折扣因素的最优关系契约。在许多例子中，如长期买卖关系、研究合资企业或非法串通协议，对其他各方行为的监控程度对关系合同的范围至关重要。我研究访问的一个目标是将我的研究结果扩展到尽可能普遍的不完善的监测形式。我的主持人拉里·萨缪尔森（Larry Samuelson）和约翰内斯（Johannes Hörner）都是重复博弈领域的顶尖专家，他们的研究重点是监控不完善的问题。我研究访问的另一个目标是了解更多关于结构计量经济学方法的知识，这些方法可以在重复的相互作用中估计公司的战略。耶鲁大学拥有新经验产业组织相关领域的世界顶尖专家，如拉尼尔·本卡德、史蒂夫·贝里或菲利普·海尔。我希望我的研究访问能够帮助我在德国为经济理论与应用计量经济学相结合的经济研究和教学做出贡献。和计量经济学。

The main goal of my research visit to Yale is to extend my research on relational contracts and the underlying theory of infinitely repeated games. In the paper Renegotiation-Proof Relational Contracts with Side Payments , joint with Susanne Ohlendorf, we characterize the set of payoffs that two parties can achieve with relational contracts under the assumptions that actions are perfectly observable, side payments are possible and the relational contracts are renegotiation-proof. Our contribution to the literature is to develop for a general framework a simple method to determine optimal relational contracts for any discount factor. In many examples, like long-term buyer-seller relationships, research joint ventures, or illegal collusive agreements, the degree to which other parties’ behavior can be monitored is crucial for the scope of relational contracts. One goal of my research visit is to extend my results to forms of imperfect monitoring that are as general as possible. My host Larry Samuelson, as well as Johannes Hörner, are leading experts in the field of repeated games, whose research has a particular focus on issues of imperfect monitoring. Another goal of my research visit is to learn more about structural econometric methods that allow to estimate firms strategies in repeated interactions. Yale hosts world leading experts in the corresponding field of new empirical industrial organization, like Lanier Benkard, Steve Berry, or Philip Haile. I have the hope that my research visit helps me contributing to economic research and teaching in Germany that combines economic theory and applied econometrics. and econometrics.
