This paper develops a lattice method for option evaluation in the presence of regime shifts in the correlation structure of assets, aiming at investigating whether the option prices reflect such shifts. Specifically we try to investigate whether option prices reflect switches in the correlation...

We consider the Schwartz 97 two and three factor models, which have been considered as benchmarks for pricing commodity derivatives in the last two decades. In order to take account of sudden regime shifts in commodity prices, we superimpose a regime shifting structure onto this framework. Using...

This paper develops a closed-form model for options on commodities under the assumptions of mean-reversion in the commodity prices and regime-switching in the commodity returns volatility. After a closed-form solution for the option value in constant regimes has been developed, the model is...
