This article examines whether volatility risk is a priced risk factor in securities returns. Zero-beta at-the-money straddle returns of the Samp;P 500 index are used to measure volatility risk. It is demonstrated that volatility risk captures time variation in the stochastic discount factor,...

This article examines agents' consumption-investment problem in a multi-period pure exchange economy where agents are constrained with the short-sale of state-dependent risky contingent claims. In equilibrum, agents hold options written on aggregate consumption in their optimal portfolios....

We examine whether there is a relationship between foreign equity trading and average total volatility, measured as the value-weighted average of stock-return variances in the Istanbul Stock Exchange. We employ foreign equity purchase and sale data to track changes in foreign equity trading,...

This study investigates excess stock price volatility using the variance bound framework of LeRoy and Porter (1981) and of Schiller (1981). The conditional variance bound relationship is examined using cross-sectional data simulated from the general equilibrium asset pricing model of Brock...

Although there is a consensus about time variation in market betas, it is not clear how this variation should be captured. Several researchers continue to analyze different versions of the conditional CAPM. However, Ghysels (1998) shows that these conditional CAPM models fail to capture the...

This paper analyzes the time-series variation in the return volatility of non-US stocks from emerging markets that are cross-listed on US exchanges. Unlike previous studies in the cross-listing literature, return volatility is modeled using conditional heteroscedas-ticity models. We find that...

In this study, we address whether the degree of financial liberalization affects the aggregated total volatility of stock returns by considering the time-varying nature of financial liberalization. We also explore channels through which the degree of financial liberalization impacts aggregated...
