Generative AI, Managerial Expectations, and Economic Activity
生成式AI、管理者预期与经济活动
Manish Jha, Jialin Qian, Michael Weber, Baozhong Yang
We use generative AI to extract managerial expectations about their economic outlook from 120,000+ corporate conference call transcripts. The resulting AI Economy Score predicts GDP growth, production, and employment up …

Usage frequency predicts lexicalization across languages
使用频率预测跨语言的词汇化
Temuulen Khishigsuren, Francis Mollica, Ekaterina Vylomova, Charles Kemp
Languages are more likely to have lexical items for some concepts (e.g. CHILD and SUN) than others (e.g. PARENT and WEATHER). We present a large-scale quantitative analysis of factors that predict lexicalization across l…

Living in a Ghost Town: The Geography of Depopulation and Aging
生活在鬼城：人口减少与老龄化的地理分布
Elisa Giannone, Yuhei Miyauchi, Nuno Paixão, Xinle Pang 等
How do depopulation and population aging evolve differently across regions within a country, and what are their implications for aggregate economic activity and regional inequality?Using spatially disaggregated data from…

QoE-Driven Hybrid Resource Allocation for Multi-User OFDMA Semantic Communications
面向多用户OFDMA语义通信的QoE驱动混合资源分配
Xiaotian Xu, Zhifeng Tang, Guangchen Wang, Nan Yang 等
In this paper, we develop a quality-of-experience (QoE)-driven hybrid resource allocation framework for multi-user downlink orthogonal frequency-division multiple access semantic communication systems, where the hybrid f…

Mesmer’s error: Beliefs reverse the rubber hand illusion (a Registered Report)
梅斯梅尔的错误：信念逆转橡胶手错觉（一项注册报告）
Peter Lush, Zoltan Paul Dienes
In the rubber hand illusion (RHI), participants report ownership of a fake hand which is stroked in synchrony with their own concealed hand, with lower ownership ratings for asynchronous stroking. This effect has been hi…

Corporate Hierarchy
企业层级结构
Xavier Giroud, Michael Ewens
We introduce a novel measure of corporate hierarchy for 3,454 U.S. public firms. We construct this measure using online resumes of 18.1 million employees and a network estimation technique that allows us to identify hier…

Three-orbifolds, positive scalar curvature and fundamental group
三轨道流形、正标量曲率与基本群
Bessières, Laurent, Sylvain Maillot, Ilaria Mondello, Thomas Richard
We show that closed Riemannian 3-orbifolds with positive scalar curvature have virtually free fundamental group. We also build a family of closed 3-orbifolds with free fundamental group of rank 2 which do not admit Riema…

A Deterministic Polynomial-Time Approximation Below One Third for Bimatrix Games
双矩阵博弈的一个确定性多项式时间低于三分之一的近似算法
Davit Gondauri
This paper proves a strict deterministic polynomial-time approximation guarantee below the one-third frontier for general two-player rational bimatrix games with payoffs normalized to [0,1]. Its central result is an expl…

A NOTE ON THE HYPERCOMPLEX SINGULAR CAUCHY-LIKE INTEGRAL IN DOUGLIS ANALYSIS
关于Douglis分析中超复奇异类Cauchy积分的一个注记
Isidro Paulino-Basurto, Jean-Marie Vilaire, Oscar Gonzalez-Cervantes, Juan Bory-Reyes
Hypercomplex analysis extends classical complex analysis to Douglis algebras, replacing holomorphic functions with hyperanalytic functions, i.e., null solutions of the Douglis operator in $\mathbb R^2$ (identifying $\mat…

A One-Saddle 1/5 Approximation Algorithm for Common-Kernel Bimatrix Games: Recognition, Exact Segment Optimization, Sharp Selector Bounds, and Certified Robustness
共同核双矩阵博弈的单鞍点1/5近似算法：识别、精确线段优化、锐利选择子界与认证鲁棒性
Davit Gondauri
This paper develops an algorithmic, structural, and certification theory for a fixed-normalization class of symmetric bimatrix games generated by a common kernel. The class arose from a broader investigation of approxima…
