Over the recent years, both in finance and insurance, the modelling of dependence beyond linear correlation has become a key area of research. The notion of copula has been used with success in order to model these more general dependence concepts. We will discuss changes in dependence...

Both at the design stage as well as at the pricing stage of Alternative Risk Transfer (ART) products, the notion of low (zero) beta plays an important role. By now it is well known that for these non--standard products, the interpretation of dependence through linear correlation (and hence the...

In this paper we test for structural changes in the conditional dependence of two-dimensional foreign exchange data. We show that by modeling the conditional dependence structure using copulae we can detect changes in the dependence beyond linear correlation like changes in the tail of the joint...

Using a sample of 76 countries, this paper examines the impact of major strikes against government and its policies on stock market behavior. An occurrence of a general strike is detrimental to the value of equities, as documented by the ceteris paribus 6.11% fall in dollar-denominated stock...

Stop-loss reinsurance is a risk management tool that allows an insurance company to transfer part of their risk to a reinsurance company. Ruin probabilities allow us to measure the effect of stop-loss reinsurance on the solvency of the primary insurer. They further permit the calculation of the...

Financial crises can cause financial portfolios to incur large losses. Methodologies for portfolio selection taking into account the possibility of large losses have existed for decades but their economic value is not established. This article investigates if there is economic value in reducing...
