题目:Optimal Hedging under Knightian Uncertainty
主讲人:Prof. Hyeng Keun Koo,School of Business Administration, Ajou University
摘要: Optimal hedging is considered under Knightian uncertainty. In complete markets, every contingent claim can be replicated with trading assets, which make its pricing irrelevant to subjective beliefs to the future states. To the contrary, in incomplete markets, an agent with an obligation from contingent claims could not fully hedge his position, so that his pricing of the contingent claims is sensitive to the beliefs to the future states. We investigate the agent's optimal hedging decision under Knightian uncertainty in a simple single-period model.
