ON A BONUS-MALUS SYSTEM WHERE THE CLAIM FREQUENCY DISTRIBUTION IS GEOMETRIC AND THE CLAIM SEVERITY DISTRIBUTION IS PARETO
In this paper, the classical Bonus-Malus Systems (BMS) under which
a premium is set by taking into account only the number of accidents
each policyholder has, is compared with an optimal BMS under which
the premium is set by taking into account both the frequency and the
severity of the claims of each policyholder. The number and size of
the claims an insured person has are assumed to follow a Geometric
distribution and a Pareto distribution, respectively.
