Abstract

We present a stochastic-market-risk extension of a popular doubly-mean-reverting Vasicek model. The model straddles the P and Q measures. By allowing for a stochastic market price of risk, we break the determninisitc link between the return-predicting factor and the market-price of risk, but we retain, on average, the observed regularities reported in the literature. We also show how the model can be calibrated.

Keywords: affine models, market price of risk, return predicting factor
