It is difficult to disagree with Vernon Smith's (2010) assessment of thestate of the art in experimental economics. It is informed by the experienceof someone who was there, right at the beginning of experimental economics.Some of the problems he discusses, like the frequent failure of backward...

Goeree & Holt (2001) observe that, for some parameter values, Nash equilibrium providesgood predictions for actual behaviour in experiments. For other payoff parameters, however,actual behaviour deviates consistently from that predicted by Nash equilibria. They attributethe robust deviations...

This paper experimentally investigates whether risk-averseindividuals punish less if the outcome of punishment is uncertain thanwhen it is certain. Our design includes three treatments: Baseline inwhich the one-shot prisoner’s dilemma game is played; CertainPunishment in which the prisoner’s...

Bubbles in asset markets have been documented in numerous experimentalstudies. However, all experiments in which bubbles occurpay dividends after each trading day. In this paper we study whetherbubbles can occur in markets without dividends. We investigate therole of two features that are...

The concept of a non-extreme-outcome-additive capacity (neo-additive capacity ) is introduced.Neo-additive capacitiesmodel optimistic and pessimistic attitudes towards uncertaintyas observed in many experimental studies. Moreover, neo-additive capacities canbe applied easily in economic...
