摘要
We have solved the problem of finding (HARA) fair option price under a general stochastic volatility model. For a given HARA utility, the 'risk premium', i.e., the 'market price of volatility risk' is determined via a solution of a certain nonlinear PDE. Equivalently, the fair option price is determined as a solution of an uncoupled system of a non-linear PDE and a Black-Scholes type PDE. (c) 2004 Academie des sciences. Published by Elsevier SAS.
