Discrete games with flexible information structures: an application to local grocery markets
提出一种放松信息结构假设的方法,以增强离散博弈实证分析的可信度,并应用于杂货店进入退出数据,发现严格假设可能导致误导性反事实结果。
Game‐theoretic models are frequently employed to study strategic interaction between agents. Empirical research has focused on estimating payoff functions while maintaining strong assumptions regarding the information structure of the game. I show how to relax informational assumptions to enhance the credibility of empirical analysis in discrete games. I apply the method to data on the entry and exit patterns of grocery stores. The model provides useful bounds on equilibrium outcomes. In addition, the empirical analysis indicates that more restrictive informational assumptions can generate qualitatively misleading counterfactual outcomes.
