Abstract

In their paper from behavioral finance, we employ dynamic programming principle on two optimal investment problems in a continuous-time Markov regime-switching setting. They model different states of an economy and, hence, investors’ floating levels of psychological reactions by a D-state Markov chain: a zero-sum game between an investor and the market, and a nonzero-sum stochastic differential portfolio game. We derive regime-switching Hamilton–Jacobi-Bellman-Isaacs equations, and explicit optimal portfolio strategies with Feynman-Kac representations of value functions. For a two-state special case the results are illustrated and the impact of regime switches observed by a comparison.
