题目:Option Pricing with Market Frictions and Regime Switching

主讲人:Professor Tak Kuen Siu  Macquarie University, Australia

摘要:

Market frictional costs prevail in financial markets and play a significant role in asset pricing as well as other important areas in economics and finance. In this talk, I shall discuss a modelling framework, which aims to integrate the impacts of three fundamental features including market frictional costs, regime switches and ambiguity on option prices. The ask and bid prices of a European option in such incomplete market are characterised as solutions of coupled nonlinear partial differential equations. An approach based on the minimisation of a relative entropy is used to determine a fair value between the ask and bid prices. A simple closed-form solution to the minimisation problem is obtained, which indicates that the fair value does not price the regime-switching risk in the presence of market frictions. Numerical experiments on the model are conducted. The numerical results indicate the significance of incorporating market frictional costs in option valuation under the regime-switching environment.
