In the standard real options approach to investment under uncertainty, agents formulate optimal policies under the assumptions of risk neutrality or perfect capital markets. However in most situations, corporate executives face incomplete markets either because they receive compensation packages...

In the standard real options approach to investment under uncertainty, agents formulate optimal policies under the assumptions of risk neutrality or perfect capital markets. Although the assumptions of risk neutrality or market completeness are crucial to the implications of the approach, they...

This article shows that, as long as agents are required to maintain positivewealth, the presence of portfolio constraints may give rise to asset pricingbubbles in equilibrium even if there are unconstrained agents in the economywho can benefit from the induced arbitrage opportunity. Furthermore,...

This paper analyzes competition between mutual funds in a multiple fundsversion of the model of Hugonnier and Kaniel [18]. We characterize the setof equilibria for this delegated portfolio management game and show thatthere exists a unique Pareto optimal equilibrium. The main result of thispaper...

This paper proposes and tests a model of firm valuation under incompleteinformation that explains the ambiguous relation between idiosyncratic volatilityand stock returns. Specifically, we show that, when investors have incompleteinformation, expected returns as measured by an econometrician...
