Abstract

In the classical Bonus-Malus System (BMS) there are several premium levels, e.g., M. A premium level i consists of a premium (π_i) and a deductible (d_i). In this paper, we consider the expected cost for a horizon of n periods of a policyholder in level i. This expectation is denoted by E_n(i). When damage of size x occurs, the policyholder should decide whether or not to claim. The minimum damage for which the policyholder will claim should be the solution of min d_i ≤x{x + E_n-1(i- 1); d_i + E_n-1(i+ 1)}: We will show that E_n-1(i-1) ≤ E_n-1(i+1), hence x =di+E_n-1(i +1) -E_n-1(i -1), is a valid solution.
