This paper proposes bonus-malus systems for fleets of vehicles, by using the individual characteristics of both the vehicles and the carriers. Bonus-malus coefficients are computed from the history of claims or from the history of safety offences of the carriers and the drivers...

This paper provides bonus-malus systems which rest on different types ofclaims. Consistent estimators are given for some moments of the mixingdistribution of a multi equation Poisson model with random effects...
