Ambiguity and Portfolio Inertia
In this paper the Portfolio Choice problem is studied under ambiguity, formalized by means of the Choquet Expected Utility. Agents are supposed to be Choquet Expected Utility maximizers and are split into two categories: optimists, who hold a concave capacity, and pessimists, who hold a convex one. Portfolio inertia is defined and analyzed. Necessary and sufficient conditions are established be...

Theories of financial markets build on portfolio choice theory, which generally assumes that preferences are of a particularly simple kind, while research on preferences has revealed that people have more sophisticated preferences.

We examine the problem of setting optimal incentives to a portfolio manager (to be employed by an investor through a contract) making an ambiguity-robust portfolio choice with respect to estimation errors in expected returns. We consider a one-period model with a set of risky assets (with multivariate normal returns) whose expected returns are estimated with uncertainty and a linear sharing rul...
متن کاملContinuous-Time Portfolio Selection under Ambiguity∗
In a financial market, the appreciation rates of stocks are statistically difficult to estimate, and typically only some confidence intervals in which the rates reside can be estimated. In this paper we study continuous-time portfolio selection under ambiguity, in the sense that the appreciation rates are only known to be in a certain convex closed set and the portfolios are allowed to be based...
