Weather inuences our daily lives and choices and has an enormous impact on corporate revenues andearnings. Weather derivatives dier from most derivatives in that the underlying weather cannot be tradedand their market is relatively illiquid. The weather derivative market is therefore incomplete....

The study of natural catastrophe models plays an important role in the prevention and mitigation of disasters. After the occurrence of a natural disaster, the reconstruction can be financed with catastrophe bonds (CAT bonds) or reinsurance. This paper examines the calibration of a real...

We generalize the classical concept of a certainty equivalent to a model where an investor can trade on a capital market with several future trading dates.We show that if a riskless asset is traded and the investor has a CARA utility then our generalized certainty equivalent can be evaluated...

This paper first provides a simple but very general framework for credit portfolio modellingwhich is based on the distinction between systematic and unsystematic risk. Unsystematicor borrower-specific risk vanishes through diversification in a very large, infinitelyfine-grained portfolio. The...

This paper delevops a tools to analyse the ordering of concordance of random vectors.

This papfer deals with distributional free inference to test for positive quadrant dependence, i.e. for the probability that two variables are simultaneously small (or large) being at least as great as it would be were they dependent.

We explore connections between the certainty equivalent return (CER) functional and theunderlying utility function. Curvature properties of the functional depend upon how utilityfunction attributes relate to Hyperbolic Absolute Risk Aversion (HARA) type utility functions.If the CER functional is...

We propose a simplified approach to mean-variance portfolio problems by changingtheir parametrisation from trading strategies to final positions. This allows us to treat,under a very mild no-arbitrage-type assumption, a whole range of quadratic optimisationproblems by simple mathematical tools...

We prove the existence of Pareto optimal allocations within sets of acceptableallocations when decision makers have probabilistic sophisticated variational pref-erences dened on random endowments in L1.[...]

This paper proposes that risk aversion encourages individuals to invest in balanced skillprofiles, making them more likely to become entrepreneurs. By not having taken this possiblelinkage into account, previous research has underestimated the impacts both of risk aversionand balanced skills on...
