Estimation of an average causal response function in a high-dimensional sample selection model with application to US Job Corps program

Average causal response function (ACRF) is a valuable tool for assessing treatment effects with dose functions, particularly in the presence of endogeneity. Motivated by the US Job Corps program, this paper studies the identification and estimation of an ACRF under sample selecti...

Dynamic capacity investment and debt financing

It is common for companies to conduct multiple capacity expansions in a growing market. In this article, we study how firms make optimal multi-stage investment timing, scale, and capital structure decisions in the context of multiple growth options and existing assets. We show th...

Determinants of intention to use AI for personal financial management among middle-aged and older adults: evidence from Vietnam and China

Purpose This study examines factors associated with older adults' intention to use artificial intelligence (AI) for personal financial management in China and Vietnam by integrating the technology acceptance model (TAM) and the knowledge–behavior gap (KBG) model. Design/methodolo...

Icarus in the Digital Economy: Navigating the Dual Impact of Platform Adoption on Manufacturing Profit Rates

ABSTRACT Using data from China's manufacturing firms (2011–2020), this study examines how digital platform adoption affects profit rates through two opposing mechanisms. The positive “turnover acceleration effect” enhances efficiency and reduces circulation time, while the negati...

Empowerment or disempowerment: the impact of GenAI use on graduate students' research innovation capability

Purpose This study aims to examine how generative artificial intelligence (GenAI) use influences graduate students' research innovation capacity in the Chinese context, with particular attention to the mediating role of research self-efficacy, the moderating effects of peer suppo...

Proper Orthogonal Decomposition-based Model-Order Reduction for Smoothed Particle Hydrodynamics Simulation—Mass-Spring-Damper System

Model Order Reduction (MOR) based on Proper Orthogonal Decomposition (POD) and Smooth Particle Hydrodynamics (SPH) has proven effective in various applications. Most MOR methods utilizing POD are implemented within a pure Eulerian framework, while significantly less attention has...

Mean Transforms of Unbounded Weighted Composition Operator Pairs

ABSTRACT In this paper, we first characterize the polar decomposition of unbounded weighted composition operator pairs in an ‐space. Based on this characterization, we introduce the ‐spherical mean transform for . We then investigate the dense definiteness of . As an application,...

Enabler or Divider? The Enabling Effects and Digital Divide Consequences of Digital Inclusive Finance on Regional Entrepreneurship

This study investigates the impact of digital inclusive finance on regional entrepreneurship using panel data from 327 Chinese cities spanning 2011 to 2023. Employing bidirectional fixed effects models, mediation analysis, and heterogeneity analysis, we find that digital inclusiv...

The Externalities of Peers' Misconduct: Evidence From Corporate Social Responsibility

ABSTRACT How do innocent firms navigate negative reputational spillovers from industry peer misconduct? We propose that non‐culpable firms leverage corporate social responsibility (CSR) as a costly‐to‐fake signal of intrinsic quality to distance themselves from tainted peers. Usi...

Resource-Efficient Simulation of Molecular Groundand Excited States Based on Contextual Subspace and Quantum SubspaceExpansion

Abstract Predicting spectra and photochemical pathways relies on the computation of molecular excited states. However, the practicality of near-term variational quantum algorithms is threatened by the prohibitive growth of measurement overheads. Integrating Quantum Subspace Expan...
