This paper investigates information acquistion in decision problems. We introduce a new notion of "better information", Accuracy-order (A-order), defined on continuous families of signals. Accuracy formalizes the idea that "a signal that is more correlated with the unknown random variable is...

This paper endogenizes the elderly's labor force participation in an overlapping generations economy under the assumption that retirement is a luxury. In a developed economy, the agents earn a high wage income when young and retire when old. This reduces the labor supply (through a low...

We consider equilibrium selection in 2x2 bimatrix games with two strict Nash equilibria in a random matching framework. The players seek to maximize the discounted payoffs, but are restricted to make a short run commitment. Modeling the friction this way yields equilibrium dynamics of the...
