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

open access: yesMathematical 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 ...

On the Numerical Solution of the Poisson Equation in the Smoothed Particle Hydrodynamics

open access: yesStudies in Applied Mathematics, Volume 157, Issue 4, October 2026.
ABSTRACT In the present work, we address some aspects related to the numerical solution of the Poisson equation within the framework of the Smoothed Particle Hydrodynamics (SPH). In this case, the Poisson equation is solved using nonlocal, kernel‐based discretizations of the differential operators (i.e., gradient, divergence, and Laplacian operators ...

The Impacts of Problem‐Posing Intervention on the Mathematical Proficiency of Undergraduate Developmental Mathematics Students' Developmental Mathematics

open access: yesSchool Science and Mathematics, Volume 126, Issue 5, Page 441-453, October 2026.
ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

Barriers and Bridges: The Trade, Productivity, and Welfare Effects of the Belt and Road Initiative

open access: yesThe World Economy, Volume 49, Issue 10, Page 2234-2254, October 2026.
ABSTRACT This paper evaluates the impact of the Belt and Road Initiative (BRI) on trade, productivity, and welfare using a multi‐country, multi‐sector Ricardian model with input–output linkages. Gravity estimates reveal asymmetric trade effects: BRI participation increases imports from China in textiles, wood and paper, and electrical machinery, while ...
