We develop a continuous-time Bayesian learning model to evaluate the composite skill of a mutual fund manager and a fund family. Our model estimates the composite skill of each fund as a function of its own performance and family performance. We show two competing effects of the family...

The wealth-consumption ratio of an investor, say, H must be calculated to solve models of optimal portfolios and asset prices. At this time there is no standard method to obtain H for investors with stochastic differential utility in incomplete markets. One reason is that boundary conditions of...

We derive the effect of plausible deniability on asset risk premia in a dynamic setting with correlated firm values, systematic risk, and risk-averse investors. Firms optimally exercise American disclosure options, which are more valuable due to the possibility that other correlated firms may...

We derive the optimal portfolio for an investor with increasing relative risk aversion in a complete continuous-time securities market. The IRRA assumption helps to mitigate the criticism of constant relative risk aversion that it implies an unreasonably large aversion to large gambles, given...
