We present a non-parametric method for calibrating jump-diffusion models to a finite set of observed option prices. We show that the usual formulations of the inverse problem via nonlinear least squares are ill-posed and propose a regularization method based on relative entropy. We reformulate...

We propose a statistical methodology to quantify the financial implications of tropical cyclone-related physical risks implied by climate change. To address the sensitivity of disaster intensity to climate change, we provide a Monte Carlo methodology to generate synthetic cyclones consistent...

Risks and opportunities related to environmental transition are usually evaluated through the use of scenarios, produced and maintained by international bodies such as the International Energy Agency. This approach assumes perfect knowledge of the scenario by the agent, but in reality, scenario...

We address the long-standing challenge of adding optimal exploration to the classic Hotelling model of a non-renewable resource. We completely solve such a model, using impulse control. The model, extending Arrow and Chang (1982), has two state variables: "proven" reserves and a finite...

The need for clean water is expected to substantially increase while further reductions of water availability in sufficient quantity and quality are projected owing to climate change and anthropogenic activities. Accordingly, the debate on water security has recently intensified and reached the...

The concept of portfolio alignment to a temperature trajectory has gained momentum among investors and regulators since the 2015 Paris Agreement recognized the importance of the financial sector for the low carbon energy transition. Yet, a clear definition and a transparent methodological...

French Abstract: Après avoir présenté les grands indicateurs environnementaux existants et leurs limites, nous proposons une définition des caractéristiques d'un indicateur pertinent et efficace dans une approche holistique : embrassant l'ensemble des enjeux environnementaux, analysant le...

We study price formation in intraday electricity markets in the presence of intermittent renewable generation. We consider the setting where a major producer may interact strategically with a large number of small producers. Using stochastic control theory, we identify the optimal strategies of...
