| Abstract | BSV (Barberis, Huang and Vishny [1998]) model is one of the most important explanative models in the area of behavioral finance. The existing BSV model is a model of how behavioral investors form beliefs, which produces both overreaction and mean-reversion for a wide range of parameter values. However, BSV model does not address the market equilibrium problems, which is critical for the asset pricing theory. Thus the following 2 questions are meaningful for the existing BSV model to be extended to an equilibrium model in which there are both BSV investors and rational investors in a market of risky asset: Will BSV model maintain its explanative power if rational investors are introduced? Who will lose money to their counterparts in trading of risky assets, the behavioral investors or the rational investors? In this paper, we present an agent-based computational model of the dynamic game between BSV investors and rational investors. The results of our model answer the above two questions. First, the introduction of rational investors to the market of risky asset will not eliminate the anomalies of overreaction and mean-reversion. We believe that it is because the unpredictability of BSV agents' behavior adds the total risk of risky asset, which in turn prevents rational investors from taking unlimited position to arbitrage. At that time, the risky asset is mispriced. Second, we do not find any evidence that the behavioral investors will lose money to their counterparts although their cognitive bias causes them to form a false kind of expectation on the future price of the risky asset. On the contrary, some weak evidence on that behavioral investors are less likely to bankrupt is reported. We contribute it to that BSV investors will be overcautious when the market price is going down continuously due to their cognitive bias, and then decrease the probability of bankruptcy. While at that time, rational investors will try to correct the market price distorted by BSV investors and thus take an additional arbitrage position, which may increase their returns, but will increase the probability of bankruptcy |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
