In this paper we consider a risk model where claims arrive according to a
Markovian arrival process (MAP). When the surplus becomes negative or the
insurer is in deficit, the insurer could borrow money at a constant debit
interest rate to repay the claims. We derive the integro-differential equations
satisfied by the discounted penalty functions and discuss the solutions. A
matrix renewal equation is obtained for the discounted penalty function
provided that the initial surplus is nonnegative. Based on this matrix renewal
equation, we present some asymptotic formulae for the discounted penalty
functions when the claim size distributions are heavy tailed.
