We propose an equilibrium model that can explain a wide range of international finance puzzles, including the high correlation of international stock markets, despite the lack of correlation of fundamentals. We conduct an empirical analysis of our model, which combines cross-country-correlated...

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 model of dynamic correlations with a short- and long-run component specification, by extending the idea of component models for volatility. We call this class of models DCC-MIDAS. The key ingredients are the Engle (2002) DCC model, the Engle and Lee (1999) component GARCH model...

models and the prior distribution are correctly specified. We explain how the policy maker's desires to protect against misspecifications of the submodels, on the one hand, and misspecifications of the prior over them, on the other, have different effects on the decision rule.

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....
