Bootstrap Tests for Nonlinear Simplex Models
Stat, 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.

Stable Price Dispersion under Heterogeneous Buyer Consideration
The RAND Journal of Economics, Volume 57, Issue 1, Page 103-121, Spring 2026.ABSTRACT We study the pricing of homogeneous products sold to customers who consider different sets of suppliers. We identify prices that are stable in the sense that no firm wishes to undercut a rival or to raise its price when rivals are able to respond by offering special deals.

Neural network field theories: non-Gaussianity, actions, and locality
Machine Learning: Science and TechnologyBoth the path integral measure in field theory (FT) and ensembles of neural networks (NN) describe distributions over functions. When the central limit theorem can be applied in the infinite-width (infinite- N ) limit, the ensemble of networks ...

Threshold-Dependent Dominance in Tail Risk Approximation
EconometricsRegulatory risk measurement under Basel III’s Fundamental Review of the Trading Book places Expected Shortfall (ES) at the center of market risk capital, yet the fourth-order Edgeworth expansion, still widely used for Value-at-Risk (VaR) and ES ...

Transactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.Abstract This article contributes empirical and conceptual insights to emerging debates on the regulation of short‐term rentals (STRs) by delving into the socio‐legal foundations of this housing market segment. Drawing on a qualitative study conducted between September 2022 and June 2023 focused on the governance of for‐profit temporary housing (i.e ...

Rearranging Edgeworth-Cornish-Fisher expansions [PDF]
This paper applies a regularization procedure called increasing rearrangement to monotonize Edgeworth and Cornish-Fisher expansions and any other related approximations of distribution and quantile functions of sample statistics.

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.The article proposes a digital twin‐driven probabilistic power flow framework that dynamically updates the probability distribution model parameters for wind, solar and load based on real‐time data. It combines the semi‐invariant method and Gram–Charlier series expansion to dynamically update the probability distribution of node voltages. ABSTRACT With

Endogenous Timing of Moves in Bertrand-Edgeworth Triopolies [PDF]
, 2012 We determine the endogenous order of moves in which the firms set their prices in the framework of a capacity-constrained Bertrand-Edgeworth triopoly. A three-period timing game that determines the period in which the firms announce their prices precedes

Physics Letters BWe propose a novel centrality definition-independent method for analyzing higher-order cumulants, specifically addressing the challenge of volume fluctuations that dominate in low-energy heavy-ion collisions.
