We introduce a discrete-time model for log-return dynamics with observable volatility and jumps. Our proposal extends … the class of Realized Volatility heterogeneous auto-regressive gamma (HARG) processes adding a jump component with time … compensating for equity, volatility, and jump risks, the generating function under the risk-neutral measure inherits analytical …

This paper provides empirical evidence that volatility markets are integrated through the time-varying term structure … of variance risk premia. These risk premia predict the returns from selling volatility for different horizons, maturities … significance from the no-arbitrage prices and bounds implied by the variance swap market. The paper examines these pricing errors …

straddles; second, we estimate the PVR in a Heston (1993) stochastic-volatility model. In both cases, the estimation is … more negative and its term structure is steeper when volatility is high. These findings are inconsistent with calibrations …

information set for the estimation of the empirical pricing kernel and, more in general, for the validity of the fundamental …

between stock returns and idiosyncratic return volatility at the firm level. By allowing for the volatility of the underlying … idiosyncratic choice variables to exhibit independent switches between a high and low volatility regime, we show that the options …' constant expected returns are composed of (i) a state dependent drift term that relates positively with the volatility regime …

heteroskedastic processes with fat-tailed innovations in returns and volatility. We provide a tractable risk neutralization framework … estimated with ease on returns using standard maximum likelihood techniques, and joint estimation on returns and a large sample …

swap rates, and the slope of the variance swap curve. To measure risk premia, we estimate a dynamic term structure model … that decomposes variance swap rates into expected variances and term premia. Empirically, we document a strong global … hypothesis that financial intermediaries are marginal investors in the variance swap market. …
