Accounting for Missing Data When Modelling Block Maxima

open access: yesEnvironmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT Modeling block maxima using the generalized extreme value (GEV) distribution is a classical and widely used method for studying univariate extremes. It allows for theoretically motivated estimation of return levels, including extrapolation beyond the range of observed data.

Generating Stable and Metastable Critical Points in Uncertain Systems via Flow‐Based Models

open access: yesExpert Systems, Volume 43, Issue 3, March 2026.
ABSTRACT This work proposes the use of conditional flow‐based generative models to learn an approximation of the distribution of the critical points of a cost function. This approximation is used to incrementally identify all critical points, in the feasible domain of said function, by iteratively alternating the sampling of the distribution and the ...

Trade costs, infrastructure, and dynamics in a global economy

open access: yesInternational Journal of Economic Theory, Volume 22, Issue 1, Page 40-62, March 2026.
Abstract This study develops a dynamic two‐country model with trade costs linked to international infrastructure stock. With variable markups and firm heterogeneity, the welfare impact of trade costs depends on firms' cost distribution. Governments engage in a dynamic public investment game, leading to multiple steady states. The dynamic equilibrium of

Purchase and production optimization in a meat processing plant

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 2, Page 1016-1051, March 2026.
Abstract This paper addresses an optimization problem concerning the purchase and subsequent material processing in a meat processing company. Unlike the majority of existing papers, we do not concentrate on how this problem concerns supply chain management, but we focus on the production stage, primarily the meat cutting.
