In a tractable stochastic volatility model, we identify the price of the smile as the price of the unspanned risks … traded in SPX option markets. The price of the smile reflects two persistent volatility and skewness risks, which imply a …-form and structural models of stochastic volatility …

In electricity markets, futures contracts typically function as a swap since they deliver the underlying over a period … averaging results in geometric swap price dynamics. Our framework allows for including typical features as the Samuelson effect …, seasonalities, and stochastic volatility. In particular, we investigate the pricing procedures for electricity swaps and options in …

We develop a discrete-time stochastic volatility option pricing model, which exploits the information contained in high …-frequency data. The Realized Volatility (RV) is used as a proxy of the unobservable log-returns volatility. We model its dynamics by … competing time-varying (i.e. GARCH-type) and stochastic volatility pricing models. The pricing improvement can be ascribed to …

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.
