A new decomposition of the optimal portfolio, in dynamic models with von Neumann--Morgenstern preferences and Ito prices, is established. The formula rests on a change of numéraire that uses pure discount bonds as units of account. The dynamic hedging demand has two components. The first hedge...

This paper derives and analyzes dynamic timing strategies of a fund manager with private information. Endogenous timing strategies generated by various information structures and skills, and associated fund styles, are identified. Endogenous fund returns are characterized in the public...

This article studies an intertemporal economy with liquidity constrained and unconstrained individuals. We use a stopping time approach to solve the finite horizonconstrained consumption portfolio problem with constant relative risk aversion and to examine the structure of equilibrium. The...

Theory predicts that funding conditions faced by financial intermediaries are an important limit to arbitrage. We identify and measure the value of funding liquidity from the cross-section of Treasury securities. To validate our interpretation, we establish linkages with funding conditions in...

We propose an asset pricing model with generalized disappointment aversion preferences and long-run volatility risk. With Markov switching fundamentals, we derive closed-form solutions for all returns moments and predictability regressions. The model produces first and second moments of...

Risk aversion functions extracted from observed stock and option prices can be negative, as shown by Aït-Sahalia and Lo (2000), Journal of Econometrics 94: 9--51; and Jackwerth (2000), The Review of Financial Studies 13(2), 433--51. We rationalize this puzzle by a lack of conditioning on latent...
