چکیده
Most learning models assume players are adaptive (i.e. they respond only to their own previous experience and ignore others' payo information) and behavior is not sensitive to the way in which players are matched. Empirical evidence suggests otherwise. In this paper, we extend our adaptive experience-weighted attraction (EWA) learning model to capture sophisticated learning and strategic teaching in repeated games. The generalized model assumes there is a mixture of adaptive learners and sophisticated players. Like before, an adaptive learner adjusts his behavior the EWA way. A sophisticated player however does not learn and rationally best-responds to her forecasts of all other behaviors. A sophisticated player can be either myopic or foresighted. A foresighted player develops multipleperiod rather than single-period forecasts of others' behaviors and chooses to `teach' the other players by choosing a strategy scenario that gives her the highest discounted net present value. Consequently a foresighted player can develop a reputation for herself by strategic teaching if she is matched with an adaptive player repeatedly. We estimate the model using data from p-beauty contests and repeated trust games. The generalized model is better than the adaptive EWA model in describing and predicting behavior. Including teaching also allows an empirical learning-based approach to reputation formation which is at least as plausible as the standard type-based approach.

متن کاملNber Working Paper Series Experimenting with Measurement Error: Techniques with Applications to the Caltech Cohort Study
Measurement error is ubiquitous in experimental work. It leads to imperfect statistical controls, attenuated estimated effects of elicited behaviors, and biased correlations between characteristics. We develop simple statistical techniques for dealing with experimental measurement error. These techniques are applied to data from the Caltech Cohort Study, which conducts repeated incentivized sur...

Division of the Humanities and Social Sciences California Institute of Technology Pasadena, California 91125 Learning Dynamics in Mechanism Design: an Experimental Comparison of Public Goods Mechanisms
In a repeated-interaction public goods economy, dynamic behavior may affect the efficiency of various mechanisms thought to be efficient in one-shot games. Inspired by results obtained in previous experiments, the current paper proposes a simple best response model in which players’ beliefs are functions of previous strategy profiles. The predictions of the model are found to be highly consiste...
