Project description This research project focuses on the incorporation of parameter risk into calculations of risk capital at insurance companies. It is assumed that the risk to be quantified can be given as random variable X (which belongs to a known distribution family, e.g. normal distribution), but that the parameter (vector) (e.g. expected value and standard deviation) can only be estimated on the basis of historical data. The quantile that is of interest when calculating risk capital can also only be estimated. The project will therefore focus on the identification of cases in which this leads to the systematic underestimation of risk capital. It will also include the development of risk capital calculation methods which ensure that parameter risk is properly taken into account. This will involve the consideration of constant variables, discrete random variables and more complex distributions (e.g. the aggregate loss distribution of the collective model). The project results will be assessed in terms of their practical relevance and presented accordingly.
