Experience Rating Using Bonus-Malus, With Applications in R

Bonus-malus system, which is used interchangeably as “no-fault discount”, “merit rating”, “experience rating” or “no-claim discount” in different countries, is based on penalizing insureds who are responsible for one or more claims by a premium surcharge, and awarding insureds with a premium discount if they do not have any claims. Insurers use bonus-malus systems for two main purposes; to encourage drivers to drive more carefully in a year without any claims, and to ensure insureds to pay premiums proportional to their risks based on claims experience. In this presentation, we relate the NCD system with a discrete time parameter Markov Chain, and show some applications of the Markov Chain model on the NCD system such as stationary distribution, convergence rate, premium evolution, and premium rating. We also show briefly the application of R on several insurance data.
