This paper studies the relationship between investor risk preferences and asset returns. The paper provides direct evidence on the risk aversion of participants in a securities market. It uses the prices of lottery bonds issued by the Imperial Russian Government in 1864 and 1866 to estimate investor risk aversion and to study changes in preferences toward risk. Time variation in investor risk p...

Using an agent-based multi-asset artificial stock market, we simulate the survival dynamics of investors with different risk preferences. It is found that the survivability of investors is closely related to their risk preferences. Among the eight types of investors considered in this paper, only the CRRA investors with RRA coefficients close to one can survive in the long run. Other types of a...

Can consumption growth risk (or consumption beta) serve a better measure of risk than market beta? This paper answers this question by testing and comparing the performance of the traditional Capital Asset Pricing Model (CAPM) and consumption-based CAPM (CCAPM) across seven financial market sub-sectors in the emerging Taiwan stock market. The empirical performance of the CAPM is encouraging. Th...

In this paper we take up Bayesian inference for the consumption capital asset pricing model. The model has several econometric complications. First, it implies exact relationships between asset returns and the endowment growth rate that will be rejected by all possible realizations. Second, it was thought before that it is not possible to express asset returns in closed form. We show that Labad...

I model a scenario in which investors do not know the payoff distributions of relatively newer firms and use the payoff distribution of similar well-established firms as starting points. The starting distributions are then adjusted for size, volatility, and other differences. Anchoring bias (Tversky and Kahneman (1974)) implies that such adjustments typically fall short. I show that adjusting c...

We examine the relation between US stock market returns and the US business cycle for the period 1960 2003. We identify two channels in the transmission mechanism. One is through the mean of stock returns via the equity risk premium, and the other is through the volatility of returns. We find that the relation is asymmetric with downturns in the business cycle having a greater negative impact o...

This paper addresses how asymmetric information, fads and Lévy jumps in the price of an asset affect the optimal portfolio strategies and maximum expected utilities of two distinct classes of rational investors in a financial market. We obtain the investors’ optimal portfolios and maximum expected logarithmic utilities and show that the optimal portfolio of each investor is more or less than it...

a r t i c l e i n f o A large number of researches have shown that the negative return of risky asset exists and has the profound significance whether for actual investment or theory studies. This paper investigates the effect of sentiment by establishing the sentiment asset pricing model, and explores the negative expected return when the parameters change in different situations. We provide t...
