This paper investigates an optimal reinsurance policy using a risk model with dependent claim and insurance premium by assuming that the insurance premium is random. Their dependence structure is modeled using Sarmanov’s bivariate exponential distribution and the Farlie–Gumbel–Morgenstern...

We give a simple explicit algorithm for building multi-factor risk models. It dramatically reduces the number of or altogether eliminates the risk factors for which the factor covariance matrix needs to be computed. This is achieved via a nested "Russian-doll" embedding: the factor covariance...

This paper reviews the two main methods used by government Social Security departments to draw up the so-called actuarial balance of the pay-as-you-go pension system, focusing especially on results, methodology and actuarial issues. The specific models studied are those in the United States,...

In this paper, we focus on the pricing of a particular life insurance contract where the conditional payoff to the policyholder is the maximum of two risky assets. The first one has larger expected returns but is riskier while the second one is less risky but still can earn more than an...

Eine einflussreiche Meinung unter deutschen Ökonomen besagt, dass es mehrere Wege gibt, »versicherungsmathematisch korrekte« Rentenabschläge bei vorzeitigem Rentenzugang zu definieren – je nach dabei verfolgten Zielen. Die relativ geringen Abschläge nach dem geltenden Recht der GRV seien...
