We develop a zero beta industry model of growth options to explain the conflicting empirical findings on the relation between stock returns and idiosyncratic return volatility at the firm level. By allowing for the volatility of the underlying idiosyncratic choice variables to exhibit...

We generalize the long-run risks (LRR) model in Bansal and Yaron (2004) by incorporating the recursive smooth ambiguity aversion preferences of Klibanoff, Marinacci, and Mukerji (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model remains...

We document that the variance risk premium in asset returns decreases firms' investments.We theoretically model the premium; we find that it increases the value of the real optionto delay an investment and, thus, influences investments negatively. Empirically, we verifythe negative link between...

I generalize the long-run risks (LRR) model of Bansal and Yaron (2004) by incorporating recursive smooth ambiguity aversion preferences from Klibanoff et al. (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model is as tractable but more flexible...

We combine risk-neutral densities from equity index options with realized index returns to estimate the market's risk aversion. Starting from a power utility framework with constant risk aversion, we extend it by more flexible stochastic discount factors. We allow for time-varying risk aversion...

This paper examines how oil and gas companies' reserves growth affects their share price returns. In particular, we examine three issues affecting the relation between reserves changes and oil and gas firm returns. First, we examine if investors value reserves replacement because of exploration...

The identification of the forces that drive stock returns and the dynamics of their associated volatilities is a major concern in empirical economics and finance. This analysis is particularly relevant for determining optimal hedging strategies based on whether shocks to the volatilities of...

We propose a comprehensive treatment of the leverage effect, i.e. the relationship between returns and volatility of a specific asset, focusing on energy commodities futures, namely Brent and WTI crude oils, natural gas and heating oil. After estimating the volatility process without assuming...

This study finds crude oil prices (`oil prices') affect market or portfolio expected returns on the NSE only via inducement of changes to risk aversion parameters of the `representative agent' who has exposure to both stock market return volatility risk and oil price risk. I refer to this effect...

We investigate the co-movement between oil-specific emotions sentiments and the crude oil returns over time-scales and frequencies. Using wavelet coherence analysis, we find that sentiment is statistically significant coherence with oil returns both over time and frequencies. The pleasant...
