A Splitting Architecture for Exact Reduced Coulomb Friction
Computer Graphics Forum, EarlyView.Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Economic Inquiry, Volume 63, Issue 2, Page 424-440, April 2025.Abstract Eaton, Kortum, and Kramarz (2011) (EKK) discovered empirical patterns from French manufacturing firms that a baseline firm heterogeneity model could not explain. The authors proposed and estimated a model that closely matches the patterns observed in French data.

Building a Potemkin village in occupied China: Japan's wartime system of linked trade, 1939–43
The Economic History Review, EarlyView.Abstract The paper discusses the novel but little‐known exchange rate system of Japanese‐occupied North China during the Second Sino‐Japanese War, in which exporters were given the right to import in the form of a piece of yellow paper, which could be sold in the secondary market.

Eigenvalue Problem in Min-Plus Algebra
Eigenvalue Problem in Min-Plus Algebra本論文では,Min-Plus代数における行列の固有値問題を取り上げる.Min-Plus代数とは様々な数学の分野で研究がされているベキ等な半環構造を持つ代数系の1つである.Min-Plus代数では一般の線形代数における様々な性質や定理がそのまま従うように思えるが,検証はされていない.そこで我々はこのMin-Plus代数における行列の固有値を調べ,何らかの特徴付けができないかを考えた.そしてMin-Plus代数における重み付き隣接行列の固有値が,その行列で実現できる重みの付いた有向グラフ(ネットワーク)の閉路平均重みと対応していることがわかり,それを証明することができた.しかし,ネットワークの全ての閉路に対して,その平均重みが重み付き隣接行列の固有値として現れるかについてはまだわかっておらず ...

Rational Expectations Fools' Bubbles
International Economic Review, EarlyView.ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.

On Spatial Point Processes With Composition‐Valued Marks
International Statistical Review, EarlyView.Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces
International Statistical Review, EarlyView.Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Is There Intersectional Labor Market Discrimination?
Industrial Relations: A Journal of Economy and Society, EarlyView.ABSTRACT We test for intersectional labor market discrimination across five dimensions: gender, race, ethnicity, sexual orientation, and disability. Specifically, we test for “amplifying intersectionality”—negative interactions between the effects of marginalized identities that make wage penalties greater than additive.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Functional longevity (FL) is a complex trait that integrates many attributes directly contributing to the successful retention and productivity of a cow within the herd. Consequently, improving FL in beef cattle increases herd profitability. This study aimed to estimate the genetic associations between two alternative FL definitions and traits
