3Intro
- Models for Pricing Energy Derivatives
- Formulated in Terms of the Spot Energy Price
- Derivatives Futures/Forwards, European Options
- Range from 1 factor Black (1976) model to a
three-factor model with stochastic convenience
yield and stochastic term structure of interest
rate - Comments seasonal factors
- Volatility Smile Numerical Techniques Chapter

30Three Factor Models
- Schwartz (1997) extension of his TFM (Vasicek
short term rate r) - Hillard Reis (1998) interest rate follows HJM
(1992) model
31Three Factor Models Schwartz (1997)
32Three Factor Models HR (1998)
33Three Factor Models PDE Schwartz (1997) HR

(1998))
36Volatility of the Futures Prices (SHR)
37TFM Option Pricing (Milstein Schwartz (1998))
38Choosing a Spot Price Model
- For Short Maturity Options on Long Maturity
Forward Contract Black Model could be used - For Short Maturity Options on Short Maturity
Forward Contract Schwartz One Factor Model could
be used - Large and Diverse Portfolio of Energy Contracts
Two Factor Stochastic Convenience Yield Model is
good
39Choosing a Spot Price Model II
- Not Necessary to Use Three Factor Model
Stochastic Interest Rate has a relatively minor
impact on Energy Derivatives Prices - Jumps?-loss of the simple analytical solutions
and numerical techniques - HR-presented a quasi-analytical solution for
standard options under 3FM with jumps but its
not consistent with the attenuation of the jumps
in the case of simple mean reversion
