We derive exact expressions for the risk premia for general distributions in a Lucas economy and show that the errors when using log-linear approximations can be economically significant when the shocks are nonnormal. Assuming growth rates are Normal Inverse Gaussian (NIG) and fitting the...

We analyze how a benevolent, privately informed government agency would optimally release information about the economy׳s growth rate when the agents hold heterogeneous beliefs. We model two types of agent: “conforming” and “dissenting.” The former has a prior that is identical to that...

We analyze banks’ pooling of corporate loans and propose Pareto-improving sharing rules that depend only on the relative sizes of the loans. Implementation of these sharing rules do not require any precise knowledge of default probabilities or default correlations.

We show in a theoretical model that the expected excess return on any asset depends on its covariance not only with the market portfolio, but also with changes in the representative agent's estimate. We test our model using GMM and compare it to the CAPM. The results suggest that adding an...
