Modeling mortality co-movements for multiple populations have significant implications for mortality/longevity risk management. A few two-population mortality models have been proposed to date. They are typically based on the assumption that the forecasted mortality experiences of two or more...

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...

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....
