Working Paper
Moral hazard, investment, and firm dynamics
We present a dynamic general equilibrium model with heterogeneous firms. Owners of firms delegate investment decisions to managers, whose consumption and investment decisions are private information. We solve the optimal contracts and characterize the implied general equilibrium. Our calibrated model has implications on the cross-sectional distribution and time-series dynamics of firms' investment, managers' compensation, and dividend payout policies. Risk sharing requires that managers' equity shares decrease with firm sizes. That, in turn, implies it is harder to prevent private benefit in ...

Optimal unemployment insurance and cyclical fluctuations
The authors study the design of optimal unemployment insurance in an environment with moral hazard and cyclical fluctuations. The optimal unemployment insurance contract balances the insurance motive to provide consumption for the unemployed with the provision of incentives to search for a job. This balance is affected by aggregate conditions, as recessions are characterized by reductions in job finding rates. We show how benefits should vary with aggregate conditions in an optimal contract. In a special case of the model, the optimal contract can be solved in closed form. We show how this ...
