This study investigates volatility spillovers to electric power from large exogenous shocks in the prices of gas, coal, and carbon emission allowances in the German energy market. Our sample ranges from 2008 to 2016 and covers periods of different market conditions. We use a general VAR-BEKK...

In this paper we study the pricing of commodity swaptions in a Heath-Jarrow-Morton framework based on stochastic spot prices, interest rates and convenience yields. We develop a complementary framework for deriving approximations of swaption prices. In the class of Gaussian models the method...

This paper suggests a stochastic volatility term-structure model applied to the pricing of electricity swaptions in the Nordic power market traded at the Nasdaq OMX Commodities exchange. The volatility structure in the model is specified as a product of a time-dependent function that handles the...
