Argentina’s “Missing Capital” Puzzle and Limited Commitment Constraints
Capital accumulation in Argentina was slow in the 1990s, despite high total factor productivity (TFP) growth and low international interest rates. A possible explanation for the ?missing capital? is that foreign investors were reluctant to take advantage of the high returns to investment seemingly offered by that small open economy under such favorable conditions, on the grounds that previous historical developments had led them to perceive Argentina as a country prone to external debt ?opportunistic defaults.? The paper examines this conjecture from the perspective of an optimal contract ...

Adverse Selection, Risk Sharing and Business Cycles
I consider a real business cycle model in which agents have private information about an idiosyncratic shock to their value of leisure. I consider the mechanism design problem for this economy and describe a computational method to solve it. This is an important contribution of the paper since the method could be used to solve a wide class of models with heterogeneous agents and aggregate uncertainty. Calibrating the model to U.S. data I find a striking result: That the information frictions that plague the economy have no effects on business cycle fluctuations.

Aggregate Dynamics in Mirrlees Economies: The Case of Persistent Shocks
I consider a neoclassical growth model with endogenous labor supply in which agents have private information about their idiosyncratic value of leisure. A key assumption is that these shocks follow a persistent stochastic process over time. For this economy I solve the economy-wide mechanism design problem of a social planner that seeks to maximize the welfare of agents, subject to incentive compatibility, promise-keeping, threat-keeping, and aggregate feasibility constraints. When preferences over consumption and leisure are logarithmic, I obtain a strong analytical result: All macroeconomic ...

Business Cycle Fluctuations in Mirrlees Economies: The Case of i.i.d. Shocks
I consider a real business cycle model in which agents have private information about the i.i.d. realizations of their value of leisure. For the case of logarithmic preferences I provide an analytical characterization of the solution to the associated mechanism design problem. Moreover, I show a striking irrelevance result: That the stationary behavior of all aggregate variables are exactly the same in the private information economy as in the full information case. Numerical simulations indicate that the irrelevance result approximately holds for more general CRRA preferences.

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 ...
