Department of Industrial Engineering & Decision Analysis [Joint IEDA / MATH seminar] - Asset Pricing with α-maxmim Expected Utility Model

10:30am - 11:45am
Room 5560 (lift 27-28)

We study an asset pricing problem in which a representative agent trades a risky stock, a risk-free asset, and human capital to maximize her preference value of consumption represented by the α-maxmin expected utility model. This preference model is known to lead to time inconsistency, so we consider intra-personal equilibrium for the representative agent and define the market equilibrium to the set of asset prices under which the intra-personal equilibrium strategy clears the market. We prove that there exists a unique market equilibrium and the asset prices are determined by the solution to a second-order ordinary differential equation. Finally, we conduct comparative statics to study the effect of the agent's ambiguity attitude on the asset prices.

This is a joint work with Jiacheng Fan and Ruocheng Wu.
