This paper applies stochastic dominance (SD) tests to examine the dominance relationships between the futures and spot markets in Hong Kong. We also analyze the preferences for the risk averters, risk seekers, prospect investors, and Markowitz investors with further in dept of their positive and...

In this paper, we develop a new stochastic dominance (SD) theory for investors with AD utility that consists of both risk-averse and risk-seeking components. Based on the SD theory we developed in our paper, we find a new solution to answer the observation posed by Friedman and Savage (1948)...

In this paper, we introduce a new Bayesian approach to explain some market anomalies. We first develop some properties on the expected earnings shock and its volatility and establish some properties of investors' behavior on the stock price and its volatility during a financial crisis and...

Lam, et al. (2010, 2012) and Guo, et al. (2015) have developed a new Bayesian approach to explain some market anomalies. In this paper we conduct a survey to examine whether the theory developed in Lam, et al. (2010, 2012) and Guo, et al. (2015) holds in the empirically by studying the behavior...
