We present a new option-pricing model, which explicitly captures the difference in the persistence of volatility under historical and risk-neutral probabilities. The model also allows to capture the empirical properties of pricing kernels, such as time-variation and the typical S-shape. We apply...

This paper investigates the relationship between volatility and liquidity on the German electricity futures market based on high-frequency intraday prices. We estimate volatility by the time-weighted realized variance acknowledging that empirical intraday prices are not equally spaced in time....

In this paper we develop a fast yet accurate formula for pricing CMS spread options in a popular class of Libor market models with stochastic volatility. This formula makes it feasible to include quoted CMS spread option prices in the general calibration procedure and by this means to recover...
