Integrated location–inventory planning for slow‐moving demands with waiting time limitations

International Transactions in Operational Research, EarlyView.
Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...

A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

Peasant Movements and the Fourth Transformation in Mexico: What Does the Theory of Collective Empowerment Tell Us?

Journal of Agrarian Change, EarlyView.
ABSTRACT This article examines peasant and Indigenous movements in Mexico since Morena's rise to power in 2018 through the lens of collective empowerment theory, a theory of political‐cultural formation. Beyond offering an empirical assessment, the theory is refined and formalized through an analysis of these movements and their relationship to ...

Strategic Stake Acquisitions in Rival Firms: Common vs. Cross‐Ownership

The Journal of Industrial Economics, EarlyView.
ABSTRACT We study how a blockholder who controls a firm should acquire a minority stake in a rival: directly, creating common ownership, or indirectly through the controlled firm, creating cross‐ownership. Common ownership generates stronger internalization of competitive externalities and allows the blockholder to capture the resulting gains without ...

Analysing reforms of social security disability pension provision in a multistage overlapping generations model

Journal of Risk and Insurance, EarlyView.
Abstract This paper introduces a multi‐stage Overlapping Generations (OLG) model of workers and retirees, segmented by disability status and eligibility for Disability Pension (DP) benefits. Extending Gertler (1999) with progressive disability stages of distinct productivity and transition probabilities, and calibrated to US data, the model generates ...

Testing Distributional Granger Causality With Entropic Optimal Transport

Journal of Time Series Analysis, EarlyView.
ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.

On Testing for Independence Between Generalized Error Models of Several Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We define generalized innovations associated with generalized error models having arbitrary distributions, that is, distributions that can be mixtures of continuous and discrete distributions. These models include stochastic volatility models and regime‐switching models with possibly zero‐inflated regimes.

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...
