Dynamic Portfolio Optimization and Asset Pricing Martingale Methods and Probability Distortion Functions (Paperback) (ISBN-13: 9783639110586)

This monograph consists of three contributions to financial and insurance mathematics. The first part considers numerical methods for dynamic portfolio optimization in the expected utility model. It compares the martingale approach to stochastic dynamic programming and provides new theoretical results relating to the Hyperbolic Absolute Risk Aversion class of utility functions. The second part considers the pricing of contingent claims using an approach developed and applied in insurance. It shows that the risk-neutral valuation can be recovered from the probability distortion function approach, thereby establishing consistency between the insurance and the financial approaches. The third part introduces dynamic portfolio optimization with risk measures based on probability distortion functions and provides a formal treatment of this class of risk measures. It employs the martingale approach to examine the consumption- investment problem in discrete time with preferences consistent with the dual (non-expected utility) theory of choice, where subjective probabilities rather than outcomes are distorted to express the investor's risk aversion.
