This paper studies the choice between centralization and decentralization of fiscal policy in a political economy setting. With centralization, regional delegates vote over agendas comprising sets of region-specific projects. The outcome is inefficient because the choice of projects is...

This paper considers a class of two-player dynamic games in which each player controls a one-dimensional action variable, interpreted as a level of cooperation. The dynamics are due to an irreversibility constraint: neither player can ever reduce his cooperation level. Payoffs are decreasing in...

A matching model is analyzed in which firms imperfectly test workers prior to hiring them. If (some) firms hire only workers who pass the test, there is an informational externality; unemployment duration is a signal of productivity. In equilibrium, if it is profitable for a firm to test, it is...
