Modeling mortality dependence for multiple populations has significant implications for mortality/longevity risk management. A natural way to assess multivariate dependence is to use copula models. The application of copula models in the multi-population mortality analysis, however, is still in...

In this paper, we investigate systemic risk of 157 insurers around the globe. We construct tail risk networks among these insurers using a single-index model for quantile regressions with a variable selection technique. We develop new network-based systemic risk indices, taking into account...

Reinsurance is the primary source of interconnectedness in the insurance industry. As such, reinsurance connectivity provides a transmission mechanism for financial shocks and potentially exposes insurers to contagion and systemic risk. In this paper, connectivity within the U.S....

Mortality is a stochastic process. We have imprecise knowledge about the probability distribution of mortality rates in the future. Mortality risk, therefore, can be defined in a broad term of ambiguity. In this paper, we investigate the effects of ambiguity and ambiguity aversion on prices of...
