On the control of the difference between two Brownian motions: an application to energy markets modeling

open access: yesDependence Modeling, 2016
We derive a model based on the structure of dependence between a Brownian motion and its reflection according to a barrier. The structure of dependence presents two states of correlation: one of comonotonicity with a positive correlation and one of ...

Capturing the extremes: a quasi-comonotonicity-based algorithm for disaggregating daily to hourly rainfall [PDF]

open access: yesHydrology and Earth System Sciences
Disaggregating daily precipitation data into hourly time scales is crucial for hydrological modelling, urban drainage design, and extreme rainfall risk assessment.

Are law-invariant risk functions concave on distributions?

open access: yesDependence Modeling, 2013
While it is reasonable to assume that convex combinations on the level of random variables lead to a reduction of risk (diversification effect), this is no more true on the level of distributions.

Robust Bernoulli Mixture Models for Credit Portfolio Risk

open access: yesMathematical Finance, Volume 36, Issue 3, Page 528-543, July 2026.
ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

The Establishment and Optimization of a Multi-Thermodynamic-State Gas Radiation Model Based on Spectral Mapping Using Intervals of Comonotonicity

open access: yesPhotonics
In infrared radiation calculations, the k-distribution method effectively improves the computational efficiency of solving the radiative transfer equation for uniform paths and achieves accuracy comparable to the line-by-line method.

Endogenous Distress Contagion in a Dynamic Interbank Model: How Possible Future Losses May Spell Doom Today

open access: yesMathematical Finance, Volume 36, Issue 3, Page 595-619, July 2026.
ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...

Persisting Disadvantages: A Study of the Dynamics of Cumulative Deprivation

open access: yesReview of Income and Wealth, Volume 72, Issue 2, May 2026.
ABSTRACT Identifying populations at risk of deprivation is crucial for effective policy design. Yet, much existing research focuses on single aspects, such as income or material deprivation, and often abstracts from deprivation dynamics. This study addresses this gap by analyzing the dynamics and socio‐economic gradient of cumulative deprivation using ...

Beyond Averages: Inequality‐Sensitive Welfare Comparisons Across the Atlantic

open access: yesReview of Income and Wealth, Volume 72, Issue 2, May 2026.
ABSTRACT Prior studies assessing welfare across countries have utilized measures that combine country‐level outcomes in income and life expectancy. However, this perspective remains blind to the fact that two countries may have the same life expectancy and/or average income but very different underlying distributions.
