Three types of agents acting on different information sets are considered: fully informed agents, insiders, and outsiders. Differences in information quality are shown to affect the properties of their optimal portfolios. For an outsider, the share of wealth invested in the stock is decreasing...

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 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
