There has been a substantial increase in the average duration of unemployment relative to the unemployment rate in the U.S. over the last 30 years. We evaluate the performance of a standard job-search model in explaining this phenomenon. In particular, we examine whether the increase in...

This paper constructs a labor-market matching model with heterogeneous workers. Due to matching frictions, there may be a mismatch of talents within a production team, forcing a worker to specialize in a task at which she is not talented. We consider a partnership model where production takes...

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...

This paper considers the optimal contract when the current (hidden) action of an agent has a persistent effect on the future outcome. The optimal contract in a two-effort choice, two-period setting is characterized analytically and numerically. In particular, we show that persistence tends to...

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate...

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,...

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor and idiosyncratic productivity shocks and frictions characterized by employment loss...
