Experimentalists frequently claim that human subjects playing games in the laboratory violate such solution concepts as Nash equilibrium and subgame perfection. This claim is premature. What has been rejected are certain joint hypotheses about preferences, knowledge, and behavior. This note...

This paper surveys the literature on group selection. I describe the early contributions and the group selection controversy. I also describe the main approaches to group selection in the recent literature; fixation, assortative group formation, and reproductive externalities.

Many previous experiments document that behavior in multi-person settings responds to the name of the game and the labeling of strategies. Usually these studies cannot tell whether frames affect preferences or beliefs. In this Dictator game study, we investigate whether social framing effects...

In the models of Young (1993a, b), boundedly rational individuals are recurrently matched to play a game, and they play myopic best replies to the recent history of play. It could therefore be an advantage to instead play a myiopic best reply to the myopic best reply, something boundedly...

We propose a political theory for the slow adoption of technology in sports and other contests. We investigate players' preferences for new technology that improves contest accuracy. Modeling accuracy as the elasticity of "production" in a standard Tullock contest, we show that players may be...

In Young (1993, 1998) agents are recurrently matched to play a finite game and almost always play a myopic best reply to a frequency distribution based on a sample from the recent history of play. He proves that in a generic class of finite n-player games, as the mutation rate tends to zero,...

It has been argued that having a contract market before the spot market enhances competition (Allaz and Vila, 1993). Taking into account the repeated nature of electricity markets, we check the robustness of the argument that the access to contract markets reduces the market power of generators....

We here develop a model of pre-play communication that generalizes the cheap-talk approach by allowing players to have a lexicographic preference, second to the payoffs in the underlying game, for honesty. We formalize this by way of an honesty (or truth) correspondence between actions and...
