| Outline of Final Research Achievements |
This project provided an answer to a long-standing open problem of finding a general method to identify equilibria in repeated games with private monitoring. This was done by an application of Partially Observable Markov Decision Problem, and simple and robust ways to sustain cooperation under misperception were identified. The project also proposed a new class of game theoretic models, revision games, to show that cooperation is sustained in one-shot relationship, through the process of revising strategies. Furthermore, detailed empirical study was conducted about a labor union of an unusual form, a striking real-life example of OLG repeated game with private monitoring. Based on hearings and data analysis, it was discovered that there is a clever way to sustain cooperation, even though labor union members have very limited information about who helped whom.
