Focusing on US and UK, we document that both the Backus and Smith (1993) finding, concerning the low correlation between consumption differentials and exchange rates, and the forward-premium anomaly, concerning the tendency of high interest rate currencies to appreciate, have become more severe...

country, representative consumers economy, we document that the risk-sharing scheme produces a non trivial dynamics of net exports and it is also capable of explaining the tendency of high interest rate currencies to appreciate.

We propose a frictionless general equilibrium model in which two international consumers with recursive preferences trade two consumption goods and a complete set of date and state contingent securities. Consumption home bias and concern for the temporal distribution of risk generate rich...

We characterize the equilibrium of a two-country, two-good economy in which agents have opposite preference bias toward one of the two consumption goods and fear model misspecification. We document that disagreement about endowments' growth prospects is a persistent endogenous outcome of this...

We propose a new entropy-based correlation measure (co-entropy) to evaluate the performance of international asset pricing models. Co-entropy summarizes in a single number the extent of co-dependence between two variables beyond normality. We document that the co-entropy of international...

We study how a concern for robustness modifies a policymaker's incentive to experiment. A policymaker has a prior over two submodels of inflation-unemployment dynamics. One submodel implies an exploitable trade-off, the other does not. Bayes' law gives the policymaker an incentive to experiment....

A policy maker knows two models. One implies an exploitable inflation-unemployment trade-off, the other does not. The policy maker's prior probability over the two models is part of his state vector. Bayes' law converts the prior probability into a posterior probability and gives the policy...
