This paper develops a general stochastic framework and an equilibrium asset pricing model theat make clear how attitudes towards intertemporal substitution and risk matter for option pricing; In particular we show under which statistical conditions option princing formulas are not...

In this paper, we characterize the asymmetric of the smile through multiple leverage effects in a stochastic dynamic asset pricing framework.

This assesses the empirical performance of an intertemporal option pricing model with latent variables with generalized the Hull-White stochastic volatility formula.

In this paper, we provided a unifying analysis of latent variable models in finance through the concept of stochastic discount factor (SDF).
