论文摘要

This paper investigates the implication of correlation ambiguity and limited participation under market equilibrium. In our model there are three types of investors: inside, sophisticated, and naive investors. The individual decision making incorporates both risk and ambiguity. Ambiguous (include both sophisticated and naive) investors trade in the same direction as inside investors, while, naive investors trade in the same direction as sophisticated investors. We demonstrate that limited participation arises from the rational decision by ambiguous investors to avoid ambiguity and, surprisingly, investors with less ambiguous information do not hold larger positions on risky assets. Changes in the ambiguity level for ambiguous investors and the fraction of three types of investors can alter equilibrium types and affect equilibrium prices.
