Definition of CDFX model.


e are modelling the quantities $X_{t}$ and $\lambda_{t}$ . The $X_{t}$ is dollar price of a foreign currency (exchange rate), see the section ( Currency exchange ). The $\lambda_{t}$ is intensity of sovereign default pertaining to the foreign currency. We use the following equations under the risk neutral measure. MATH where the $X,v,\lambda,z$ are stochastic processes, MATH are standard Brownian motions under the risk neutral measure, MATH are constant parameters, $q$ is the random jump magnitude and $\zeta$ is the martingale normalization constant.

The $r_{t}$ and $r_{t}^{f}$ are stochastic riskless rates of accrual on dollar and foreign MMAs. We will also use the notations MATH , MATH . These processes are determined by the term structure of bond prices MATH

The $q$ is modelled as a normal variable MATH .

The $N_{t}$ is a Poisson process, see the section ( Poisson process ).

The MATH are subsequently assumed to be 0.
