This paper studies welfare consequences of consumer-side market transparency with endogenous entry of firms. Different from most studies, we consider the unique symmetric entry equilibrium, which is in mixed strategies. We identify two effects of market transparency on welfare: a competition...

We study optimal incentive contracts offered to teams where team members feel a social pressure to exert similar effort levels. The team consists of two groups of agents differing in their productivity. We characterize first best and the equilibrium under agency. Regarding economic incentives,...

This paper provides sufficient and partially necessary conditions for the equivalence of symmetric Nash and evolutionary equilibrium in symmetric games played by finite populations. The conditions are based on generalized constant-sum and "smallness" properties, the latter of which is known from...

Abstract We model a Hotelling market with multidimensional product differentiation in an evolutionary framework. Both evolutionary stability (in the sense of Schaffer, 1989) and stochastic stability (following [Kandori et al., 1993] and [Young, 1993]) are analyzed. It is shown that firms move...

The empirical literature on happiness finds that employment significantly contributes to well-being. We propose a dynamic model that explains why individuals may nonetheless be reluctant to pick up low-paid work. Accepting low-paid work will put them in an adverse position in future wage...
