We will launch within the next few days the Third Actuarial Pricing Game. The goal will be to replicate the behavior of insurance markets over time. There will be a first stage (January-February) where players will have to build a pricing model for motor insurance policies on the basis of 50,000 contracts observed Year 0 (characteristics of contracts, policyholder, and claims datasets). Proposals for premiums for Year 1 will have to be provided for the same contracts (updated for the age, the location, the car model, etc.). Players will use only the underwriting datasets to provide premiums for Year 1.Between February 25th (deadline for the proposal for premiums) and March 1st, we will replicate an insurance market by creating competition among insurers (players), and by setting simple rules to match drivers and insurers (randomly among the cheapest at the beginning of the game, and then, as time goes by, we will add inertia, i.e. a tendency to stay with the same insurer if the latter is not too expensive). Once the drivers and the playees are matched we will provide claims information for the insured that each player has won. A new premium proposal must then be submitted at the end of Year 1 (i.e. at the end of March). Etc.We will here try to replicate the a car insurance market over four years. The goal (for players) will be to maximize the profit of the insurance company over those four years. To make the game more realistic, insurers are assumed to have capital, and they can remain in the game only if their yearly loss ratio (claims over premium) is less than 150%. More information next week (rules, and training datasets).
