Adaptive learning and punishment are highly prominent competing explanations for ultimatum game behavior. We report on … an experiment that considers each theory in stand-alone form, so that one does not rely on the other in any substantial … way. Our data exhibits patterns for which punishment can account but learning by itself cannot. Initial play varies …

payoff-based learning models are simulated in order to understand individual learning behavior in distributed systems. Under … the serial mechanism the payoff-assessment learning model (Sarin and Vahid (1997)) provides the best fit to the data …, followed by the experience-weighted attraction learning model (Camerer and Ho (1999)), which in turn, is followed by a simple …
