|Pareto Weights as Wedges in Two-Country Models|
with , , : w21773
In models with recursive preferences, endogenous variation in Pareto weights would be interpreted as wedges from the perspective of a frictionless model with additive preferences. We describe the behavior of the (relative) Pareto weight in a two-country world and explore its interaction with consumption and the real exchange rate.

|Risk and Ambiguity in Models of Business Cycles|
with , : w20319
We inject aggregate uncertainty - risk and ambiguity - into an otherwise standard business cycle model and describe its consequences. We find that increases in uncertainty generally reduce consumption, but they do not account, in this model, for either the magnitude or the persistence of the most recent recession. We speculate about extensions that might do better along one or both dimensions.
