Dr. Pablo Olivares, Ryerson University

Title: Pricing and Hedging some Crack and Spark Contracts in Energy

Markets under Levy Processes
Abstract: We discuss the pricing of some derivative contracts in the Energy market whose
payoff depends on the value of multiple assets. In particular, we focus on European and Barrier
options having electricity, gasoline, natural gas and uranium as underlying assets. In order to capture
their particular dynamic, we consider models with discontinuous jumps and mean reverting
properties. Several ad-hoc approximations and numerical issues are analysed.
