The aim of this paper is to investigate the empirical relationship between daily fluctuations in the risk premium for holding a large diversified credit portfolio, which we approximate by a benchmark credit index, and some tradeable market factors which capture systematic risk. The analysis is...

Model risk has a huge impact on any risk measurement procedure and its quantification is therefore a crucial step. In this paper, we introduce three quantitative measures of model risk when choosing a particular reference model within a given class: the absolute measure of model risk, the...

We consider the problem of cost assessment in the context of switching stochastic regimes. The dynamics of a given asset include a background noise, described by a Brownian motion and a random shock, the impact of which is characterized by changes in the coefficient diffusions. A particular...

Large systematic risks, such as those arising from natural catastrophes, climatic changes and uncertain trends in longevity increases, have risen in prominence at a societal level and, more particularly, have become a highly relevant issue for the insurance industry. Against this background, the...

The aim of this paper is to investigate the empirical relationship between daily fluctuations in the risk premium for holding a large diversified credit portfolio, which we approximate by a benchmark credit index, and some tradeable market factors which capture systematic risk. The analysis is...

The aim of this paper is to determine the optimal structure of a weather bond, i.e. a bond whose coupons depend on the occurence of a weather event. The stress is put more on the structuration than on the simple pricing of the bond. Therefore, instead of looking only at the bond issue, we...

We develop a methodology for optimal design of financial instruments aimed to hedge some forms of risk that is not traded on financial markets. The idea is to minimize the risk of the issuer under the constraint imposed by a buyer who enters the transaction if and only if her risk level remains...

Without its primary flood defenses, a large part of the Netherlands would be swallowed by rivers and the sea. Floods caused by the failure of primary flood defenses are high-impact, low-probability events that are notoriously difficult to insure. Private insurance was long considered unfeasible...

In the United States and most industrialized countries, regulatory policies pertaining to food safety, occupational health, and environmental protection are (according to laws and statutes) science based. The complexity of some ecosystems and new technologies, however, makes it increasingly...

The aim of this paper is to determine the optimal structure of derivatives written on an illiquid asset, such as a catastrophic or a weather event. This transaction involves two agents: a bank which wants to hedge its initial exposure towards this illiquid asset and an investor which may buy the...
