Mobile Payment Adoption in China: A Comment on Vatsa et al.

open access: yesManagerial and Decision Economics, Volume 47, Issue 2, Page 425-437, March 2026.
ABSTRACT Vatsa et al. examine the determinants of mobile payment adoption in China. They do so by applying a probit model to data from a nationally representative survey. In this comment, we identify several conceptual and econometric limitations that affect the robustness of Vatsa et al.'s findings.

Migration, Stretched Households and the Loneliness of Older Adults in South Africa

open access: yesPopulation, Space and Place, Volume 32, Issue 2, March 2026.

It investigates the loneliness reports of older African adults in the South African context, where out‐migrants are reported as retaining membership in their household of origin.

A Generalization Error Bound of Physics‐Informed Neural Networks for Ecological Diffusion Models

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT Ecological diffusion equations (EDEs) are partial differential equations (PDEs) that model spatiotemporal dynamics, often applied to wildlife diseases. Derived from ecological mechanisms, EDEs are useful for forecasting, inference, and decision‐making, such as guiding surveillance strategies for wildlife diseases.

Bootstrap Tests for Nonlinear Simplex Models

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT We provide important contributions regarding hypothesis tests on the class of nonlinear simplex regression models. The performance of traditional asymptotic tests based on the maximum likelihood estimation (MLE) tends to exhibit considerable size distortions in finite samples.
