and to increase the level of long term investment. In this case, partial integration opens up the opportunity for the occurrence of extreme events. That is, the cost of liquidity can become unusually high and the optimal consumption can display both higher volatility than in autarky and negative...

We explore this class of models for two reasons. The first is that it appears to capture many of the aspects often ascribed to fluctuations, the role of animal spirits in affecting demand---spirits that we interpret here as coming from a rational reaction to signals about the future---, the role...

We characterize the optimal incentive scheme for a manager who faces costly effort decisions and whose ability to generate profits for the fim varies stochastically over time. The optimal contract is obtained as the solution to a dynamic mechanism design problem with hidden actions and...

We study how the heterogeneity of information impacts the efficiency of the business cycle and the design of optimal fiscal and monetary policy. We do so within a model that features a standard Dixit-Stiglitz demand structure, introduces dispersed private information about the underlying...

the potential heterogeneity in priors.
