中文摘要: 随着前景理论研究和应用的深入,人们逐渐意识到它的一个重要不足之处在于没能为参照点的形成提供理论依据,这使得学者们在应用前景理论研究金融市场时,对参照点的选取过于主观,以致得出相互矛盾的结果。本项目将在Koszegi和Rabin(2006-2010)理论工作的基础上,将参照点拓展为随机参照系,分别考察外生和内生参照系的形成机制及其对投资者风险态度的影响,进而在资产定价框架下探讨参照系对股票价格的影响,并实证检验随机参照系的引入能否提高前景理论对股票溢价之谜、动量效应和特质性波动率之谜的解释力。预期成果能进一步增进人们对前景理论和行为资产定价机制的认识,有较强的理论创新和实践指导意义。

英文摘要: With the development and application of prospect theory, people come to realize that to accommodate empirical behaviors, the outcomes hinge critically upon the specification of reference. To reconcile the seemingly contradictory predictions associated with different references, an ongoing research effort is made to understand the formation of references in practice. Building on the seminar work of Koszegi and Rabin (2006-2010) which treats references as random variables, this project intends to formulate the formation of exogenous and endogenous references respectively, explore their impacts on risk attitudes and asset prices, and examine empirically whether these references matter in explaining the equity premium puzzle, the momentum effect and the idiosyncratic volatility puzzle. The project would shed new lights on prospect theory and behavioral asset pricing.
