ON THE ORIGIN OF CONVENTION: EVIDENCE FROM COORDINATION GAMES*
通过协调博弈实验，区分基于标签和基于群体的惯例形成机制，发现两群体加标签最有效，并估计出指数虚拟博弈模型最能拟合个体行为。
We report the results of a coordination game experiment. The experiment carefully distinguishes between conventions based on labels and conventions based on populations. Our labels treatments investigate the abstraction assumptions that underlie the concept of a strategy, while our population treatments investigate the attraction of alternative mutually consistent ways to play under adaptive behaviour. We observe conventions emerging in communities with one population and labels and with two populations and no labels, but the most effective treatment is two labelled populations. We estimate logistic response learning models for individual subject behaviour. Of the models considered, a version of exponential fictitious play fits our data best.
