Solving Stochastic Climate‐Economy Models: A Deep Least‐Squares Monte Carlo Approach

Mathematical Finance, Volume 36, Issue 4, Page 751-770, October 2026.
ABSTRACT Stochastic versions of recursive integrated climate‐economy assessment models are essential for studying and quantifying policy decisions under uncertainty. However, as the number of state variables and stochastic shocks increases, solving these models via deterministic grid‐based dynamic programming (e.g., value‐function iteration/projection ...

The concept of comonotonicity in actuarial science and finance : theory. [PDF]

n an insurance context, one is often interested in the distribution function of a sum of random variables. Such a sum appears when considering the aggregate claims of an insurance portfolio over a certain reference period.

Solar Energy Risks: Stochastic Radiation Modeling and Optimal Hedging Strategies

Mathematical Finance, Volume 36, Issue 4, Page 663-699, October 2026.
ABSTRACT The growing integration of solar power into electricity markets increasingly demands advanced risk management tools to address the inherent variability of solar radiation and its interaction with electricity prices. This paper introduces a novel framework for modeling and pricing new financial instruments designed to link payoffs directly to ...

Bayesian Inference for Hawkes Processes With Stochastic Excitations

Journal of Probability and Statistics
Classical Hawkes processes assume deterministic excitation decay, limiting their ability to capture the heterogeneity and randomness of influence magnitudes observed in real-world systems such as political violence, finance, and social interactions ...

EVALUATING EFFECTIVENESS OF IRON CONDOR AND SHORT STRANGLE STRATEGIES AS HEDGING INSTRUMENTS FOR NIKKEI 225 INDEX: A STANDARD AND ANTITHETIC MONTE CARLO APPROACH

Barekeng
Global equity markets, including the Nikkei 225 Index, often experience high volatility due to economic and geopolitical factors. Sudden price changes may cause significant losses, making hedging essential for managing extreme risks and preserving ...

Interferon beta drives therapy resistance in a patient‐derived model of high‐grade serous ovarian cancer

Molecular Oncology, Volume 20, Issue 9, Page 2323-2339, September 2026.
Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

Applied Economic Perspectives and Policy, Volume 48, Issue 4, Page 1119-1134, September 2026.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...

From Cure Rate Models to Explainable Survival Analysis: SurvSHAP Based Insights for Credit Risk

Applied Stochastic Models in Business and Industry, Volume 42, Issue 5, September/October 2026.
ABSTRACT This study proposes a unified credit risk framework that combines mixture cure rate models with time‐varying SurvSHAP(t) explanations. The model separates the risk of default into incidence submodel (whether default occurs) and latency submodel (when default occurs among susceptibles).

Gradient‐Based Optimization Modeling of Total Entropy and Heat Transfer in Exothermic Blood Analog Gold Nanoparticle Suspension

Engineering Reports, Volume 8, Issue 9, September 2026.
This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...
