Estimation of generalized tail distortion risk measures with applications in reinsurance
提出了广义尾部扭曲风险测度的新估计方法，用于评估极端风险，并在汽车保险索赔数据上测试了基于该测度的再保险保费原则，有助于在定价中嵌入安全附加费以应对统计不确定性。
Abstract We present new estimators for generalized tail distortion (GTD) risk measures to assess extreme risks. Proposed estimators are based on the first‐order asymptotic expansions of the risk measure. They are simple to apply, and they are shown through simulation experiments to provide performance that is comparable or even better than that of existing estimation methods from the literature. A reinsurance premium principle based on the GTD risk measure is proposed. It is tested on car insurance claims data. We propose to use the GTD risk measure and the corresponding reinsurance premium to embed a safety loading in pricing, protecting against statistical uncertainty.
