Interpreting the Change of the Age and Experience Coefficient in Motor Third-Party Liability Insurance

The article highlights the influence of the equity factor in the insurance industry on the example of the age and driving experience coefficient development in the motor third-party liability insurance (MTPL). The aim of the research is to study risk level variation in the car insurance industry depending on the age and experience of a driver. The authors consider the Automated Information System (AIS) data of MTPL as a methodological basis of the article. The results show that the risk level depends on each of the parameters, in particular, risk levels for older drivers are lower by comparison with younger drivers with the same level of driving experience. On this basis, the authors design a two-dimensional table to assess risk levels where the risk level between separate cells differ in five times. The study presents and analyses the actuarial calculations which served as a foundation for the MTPL policy change in 2018* 1. The article provides recommendations on improving MTPL tariffing within the modern model framework and motor tariff liberalization. The study allowed the authors to verify theoretical assumptions and find direct mathematical relations between the age and experience coefficient and its constituent data. The authors concluded that it is reasonable to introduce additional categories of drivers taking into consideration demographic changes and retirement age increase. The results of the research may improve MTPL affordability and have practical utility for motor insurers in transition to individual tariffs. They also can help to address discussions and approaches to estimate a coefficient of age and experience (CAE) set by Article 9 of the Federal law of 25.04.2002 No. 40-FZ “About obligatory insurance of civil liability of owners of vehicles”.
