We propose that a simple ?dual-self? model gives a unified explanation for several empirical regularities, including the apparent time inconsistency that has motivated models of quasi-hyperbolic discounting and Rabin?s paradox of risk aversion in the large and small. The model also implies that...

We examine the role of off-path "superstitions" in macro-economics, and show how a false belief about off-path play is the key element underlying both the Lucas Critique and the game-theoretic concept of self-confirming equilibrium. However, the impact of false beliefs in these two cases is...

In economics, most noncooperative game theory has focused on equilibrium in games, especially Nash equilibrium and its refinements. The traditional explanation for when and why equilibrium arises is that it results from analysis and introspection by the players in a situation where the rules of...

In this paper we consider a number of different ways that a sequence of discrete-time repeated games can approach a continuous-time limit. Our purpose is to clarify the effects of three different factors: 1) The distribution of signals in a fixed discrete-time game, 2) How the distribution (and...
