A simulation investigation of the effect of default insurance on the optimal equity allocation and deficit spread period of a model defined benefit pension scheme is performed, using the old and new frameworks of the Pension Protection Fund in the U.K. as a starting point. The old default...

We show that by modeling the time series of mortality rate changes rather than mortality rate levels we can better model human mortality. Leveraging on this, we propose a model that expresses log mortality rate changes as an age group dependent linear transformation of a mortality index. The...

The aim of this paper is to operationalize claims reserving based on general insurance individual claims data. We design a modeling architecture that is based on six different neural networks. Each network is a separate module that serves a certain modeling purpose. We apply our architecture to...

We test for the occurrence of extreme-value dependence between equity returns of European insurance companies. The results show that this form of dependence is evident among insurance companies, in particular among the larger composite insurers. Looking at which factors drive the occurrence of...

We analyze Berkshire Hathaway's equity portfolio over the 1976 to 2006 period and explore potential explanations for its superior performance. Contrary to popular belief, we find Berkshire Hathaway invests primarily in large-cap growth rather than quot;valuequot; stocks. Over the period the...

Parameter shrinkage is known to reduce fitting and prediction errors in linear models. When the variables are dummies for age, period, etc. shrinkage is more commonly applied to differences between adjacent parameters, perhaps by fitting cubic splines or piecewise-linear curves (linear splines)...

We analyze the impact of the real-estate/mortgage crisis on the dependence between the market for common stocks and returns on Real Estate Investment Trusts (REIT's), using a flexible mixed-copula approach. We find that the impact of the crisis on the levels of the tail dependence is very...
