A Class of Stochastic Volatility HJM Interest Rate Models

This paper considers a class of stochastic volatility HJM term structure models with explicit finite dimensional realisations. The resulting bond market is arbitrage free but incomplete resulting in a non-unique martingale measure. Nevertheless, the market price of risk is partially determined by the forward rate drift and volatility. Numerical simulation for bond and bond option prices are included to illustrate the effect of stochastic volatility on these prices
