Behavioral finance studies the application of psychology to finance, with a focus on individual-level cognitive biases. I describe here the sources of judgment and decision biases, how they affect trading and market prices, the role of arbitrage and flows of wealth between more rational and less...

This paper uses the cross-sectional variance of the betas from the CAPM model to study herd behavior towards market index in Romania. For time-varying beta determination, three different modeling techniques are employed: two bivariate GARCH models (DCC and FIDCC GARCH), two Kalman filter based...

About 86 percent Indonesian are Muslim, yet the asset share of Indonesian Islamic banks is only about 4 percent. Since Islamic scholars unanimously argue that bank interests are...

This paper studies the impact of background risk on the indifference curve. We first study the shape of the indifference curves for the investment with background risk for risk averters, risk seekers, and risk-neutral investors. Thereafter, we study the comparative statics of the change in the...

In a world characterized by the occurrence of uncontrollable and extreme events investors are often required to make decisions on the basis of the available information. The challenge they face is how to manipulate these information sets in order to get what can lead them to the optimal...

In this paper we state and prove some new results about the optimal boundaries. These boundaries (also called Pareto boundaries or efficiency boundaries or maximal/minimal boundaries) are of increasing importance in the applications to Decision Theory and Economics. First of all the Pareto...

Leshno and Levy (2002) extend stochastic dominance (SD) theory to almost stochastic dominance (ASD) for {\it most} decision makers. When comparing any two prospects, Guo, et al.\ (2013) find that there will be ASD relationship even there is only very little difference in mean, variance,...

Traditional theories of finance assume that investors use all available information and make rational investment decision but in reality the scenario is different. Based upon the growing importance of behavioral finance the present study is an attempt to investigate the effect of behavioral...
