This note contributes to the discussion of decision problems with imperfect recall from an empirical point of view. We argue that, using standard methods of experimental economics, it is impossible to induce (or control for) absent-mindedness of subjects. Nevertheless, it is possible to test...

This paper constructs a small open economy version of the two sector Benhabib-Farmer (1996) indeterminacy model. It can be shown that sunspot equilibria arise at significantly lower magnitude of increasing returns to scale than in the original dosed economy model. Furthermore, if a mix of...

This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...

Studying evolutionarily successful behavior we show in a general framework that when individuals maximizing payoff differentials invest resources in punishing others. Interestingly, these investments are increasing in individuals, own wealth and decreasing in the wealth of others.
