Title: A sensitivity analysis of the long-term expected utility
of optimal portfolios

Speaker: Professor Hyungbin Park

This talk discusses the sensitivity of the long-term expected utility
of optimal portfolios. Under an incomplete market given by a factor
model, we consider the utility maximization problem with long-time
horizon. The main purpose is to find the long-term sensitivity,
that is, the extent to how much the optimal expected utility is
affected in the long run for small changes of the underlying factor
model. the tlong-term behavior of the optimal expected utility can
be characterized by a solution par of an ergodic HJB equation, and
we will conclude that this solution pair determines the long-term
sensitivity. As examples, explicit results for several market models
such as the Kim-Omberg model for stochastic excess returns and the
Heston stochastic volatility model are presented. This is joint
work with Stephan Sturm.
