We consider two players facing identical discrete-time bandit problems with a safe and a risky arm. In any period, the risky arm yields either a success or a failure, and the first success reveals the risky arm to dominate the safe one. When payoffs are public information, the ensuing free-rider...

Die Messung und Bewertung von Katastrophenrisiken stellt sich als sehr bedeutsames Gebiet dar, da sie einen großen Teil des gesamten Risikokapitals der Unternehmen binden. Aus diesem Grund soll der vorliegende Aufsatz zwei konkrete Ansätze zur Modellierung von Katastrophenschäden am Beispiel...

This paper shows that pricing catastrophe bonds boils down to computing first-passage time distributions of jump-diffusion processes. It derives a generic valuation expression by assuming that the jump risk is not systematic and then performs simulations, which can stress the sensitivity of...

High losses generated by natural catastrophes reduce the availability of insurance. Among the ways to manage risk, the subscriptions of participating and non-participating contracts respectively permit to implement the two major principles in risk allocation: the mutuality and the transfer...

Using data for 2002-2005 on a representative survey of French farms (FADN-RICA), we investigate the different factors that lead farmers to insure against crop risk. Our analysis takes into account a mix of both standard individual, financial and agricultural criteria. Cross-sectional and...

This dissertation consists of three papers referring to the pricing of insurance-linked securities, while a fourth one deals with investigating the dynamics of foreign exchange implied volatility and correlation surfaces. The first paper proposes a novel risk-neutral pricing approach for...
