We consider mortgages including the possibility of an unemployment ins
urance. The insurance company pays the cash flows of the credit as soo
n as the borrower becomes unemployed, for a maximal number of payments
fixed in the contract. We develop a probabilistic model for describin
g the cash flows paid by the insurance company. We jointly take into a
ccount unemployment, job search and prepayment phenomena. With such a
model it is possible to study the probabilistic properties of the cash
flow pattern as a function of the age of the credit. Finally, we disc
uss the estimation of the parameters of such a model and its use for p
ricing the insurance contract. (C) 1997 Elsevier Science B.V.
