In non-life insurance, the policyholder pays a fixed premium in advance of a certain period (one year) and in return, the insurance company covers the financial risk within this period. The calculation of the premium is based on the expected loss. If this expectation changes after the premium was fixed, the insurance company has to pay in case of additional losses without contribution of the policyholder. This change is called claim inflation.
Within this thesis, we investigate different approaches to explain the claim inflation by macroeconomic variables such as price inflation or changes in wage costs. We will first analyse the data of a third party liability insurance to measure the historic claim inflation. Hereby, we especially want to take changes in the composition of the portfolio of insured people into account. Second, we will fit different regression models. Afterwards, the performance of these models versus the measured claim inflation will be compared during a forecasting period. In the end, we will use our results to derive recommendations to model Claim inflation in the future.
