Quantum Algorithms for Computational Economics: A Critical Review of Simulation, Optimization, and Near-Term Evidence

This critical review argues that while quantum computing offers problem-specific advantages for computational economics—particularly in derivative pricing, risk measurement, and network optimization—it lacks a general-purpose algorithm, necessitating a shift in research focus toward reproducible benchmarks, rigorous resource accounting, and evaluations based on economic value rather than hardware novelty.

Can green credit subsidy policies improve green innovation in heavily polluting enterprises?

Using a difference-in-differences model on A-share listed heavily polluting enterprises from 2012 to 2023, this study demonstrates that green credit subsidy policies effectively promote both substantive and strategic green innovation by enhancing external supervision, improving firm reputation, and reducing environmental compliance costs, with effects varying across ownership, scale, and regional regulatory contexts.

Legal Disparities and Gendered Entrepreneurship: The Moderating Roles of Educational and Earnings Gaps

This paper utilizes cross-country panel data to demonstrate that while legal parity in entrepreneurship laws generally increases the female-to-male ratio of opportunity-driven entrepreneurship, this positive effect is strengthened in contexts where pay-based legal parity and educational equality are weaker, suggesting a substitution effect between different forms of legal and social equality.
