We analyze the valuation partial differential equation for European contingent claims in a general framework of stochastic volatility models where the diffusion coefficients may grow faster than linearly and degenerate on the boundaries of the state space. We allow for various types of model...

In this paper, we take into account a very general setting with : (i) a set of stochastic investment opportunities, (ii) a set of risky assets, (iii) a riskless asset paying a stochastic interest rate, (iv) a stochastic inflation risk, (v) stochastic labor income , and (vi) HARA preferences. We...

We take into account: (i) a set of stochastic investment opportunities, (ii) a set of risky assets, (iii) a stochastic riskless interest rate, (iv) stochastic labour incomes, and (v) HARA preferences. Without specifying any particular functional form for drifts and diffusions of all the...
