Title:Limited Participation and Asset Allocation under Ambiguity of Correlation

Presenter: Prof. Shunming Zhang

Hosted by Prof. Ying Fan

Abstract:

This paper investigates the implication of correlation ambiguity for investors' decision making and limited participation under market equilibrium. In our multi-asset model with inside, sophisticated, naive, and noise investors, individual decision making incorporates both risk and ambiguity. Sophisticated and naive investors trade in the same direction as inside investors, while naive investors trade in the same direction as sophisticated investors. Furthermore, noise investors trade in the same direction as sophisticated and naive investors. We demonstrate that limited participation arises from the rational decision by sophisticated and naive and noise investors to avoid correlation ambiguity. Comparative static analysis of the equilibrium result suggests that changes in the ambiguity level for sophisticated and naive investors and the fraction of four types of investors can alter equilibrium types and affect equilibrium prices. We also observe flight to quality phenomenon. Under equilibrium, the investors with less information could trade more intensively than the investors with more information in one of the risky assets.
