This paper considers the optimal contract when the current (hidden) action of an agent has a persistent effect on the future outcome. In this setting, the current outcome is not only a signal of the current action taken by the agent, but also conveys information about his past actions. The...

We build a general equilibrium model that features uninsurable idiosyncratic shocks, search frictions and an operative labor supply choice along the extensive margin. The model is calibrated to match the average levels of gross flows across the three labor market states: employment,...

This paper analyzes the effects of entry regulations and firing costs on cross-country differences in income and productivity. We construct a general equilibrium industry- dynamics model and quantitatively evaluate it using the cross-country data on entry costs and firing costs. Entry costs...

We build a model that incorporates both labor supply and frictions and use it to assess the effects of various tax and transfer programs on aggregate employment and unemployment. In particular, we assess the debate between Prescott and Ljungqvist and Sargent about the relative importance of...

We investigate the welfare effects of eliminating business cycles in a model with substantial consumer heterogeneity. The heterogeneity arises from uninsurable idiosyncratic uncertainty in preferences and employment status. We distinguish between short- and long-term unemployment. Long-term...
