Market Structure, Competition, and the Profitability–Stability Trade-off in Bangladeshi Banking: A Unified Panel Analysis

This study of Bangladesh's banking sector (2001–2020) reveals a concave relationship between market concentration and profitability with an optimal threshold around CR3 ≈ 0.37, while demonstrating that both higher concentration and larger loan market shares undermine financial stability, suggesting a competition-fragility dynamic where moderate concentration boosts returns but excessive concentration erodes them and increases systemic risk.

Critical Mineral Supply Restrictions and Global Technological Change: Micro-Evidence from Export Controls on Magnetic Rare Earths

Using global panel data and a continuous triple-differences model, this study demonstrates that China's export controls on magnetic rare earths have compelled downstream firms to intensify path-dependent R&D and expand patenting efforts rather than pursue risky cross-disciplinary innovation, thereby revealing the micro-level mechanisms through which critical mineral supply shocks drive global technological change.

Privacy Conscious Integration of Artificial Intelligence and Management Information Systems for Secure and Sustainable Consumer Device Lifecycles in the United States

Based on a quantitative study of 300 U.S. consumer product employees, this paper demonstrates that the secure and sustainable performance of consumer device lifecycles is best achieved not by managing privacy, AI, and MIS initiatives in isolation, but through their integrated convergence, with MIS-driven operational integration emerging as the most significant predictor of success.

Historical Coefficient Fields: A Controlled Evaluation of Geometric Market-Memory Representations for Financial Forecasting

This paper presents a controlled evaluation of the Historical Coefficient Field (HCF), a geometric representation of market history, and concludes that despite its theoretical grounding in delay-coordinate reconstruction and topological analysis, it fails to improve directional forecasting accuracy over simple baselines across diverse financial instruments, thereby demonstrating that such geometric organization carries no predictive signal beyond existing simple statistics.

Towards Sustainable Food Governance in Informal Dairy Markets: Evidence from Regulatory Surveillance and Digital Traceability in Pakistan

Drawing on Principal–Agent Theory, this study demonstrates that integrating digital traceability and collaborative governance can effectively mitigate information asymmetries and reduce milk adulteration in Pakistan's informal dairy sector, advocating for a shift from reactive enforcement to evidence-based regulatory frameworks for sustainable food safety.

An Explanation for Individually Rational, Voluntary Investment in Communal Capital in Large Groups:Toward a Population Pressure – Production Theory of Social Order

This paper argues that in large groups facing fixed land resources, increased population pressure creates conditions where individually rational agents voluntarily invest in communal capital to maximize free time, thereby explaining how high levels of cooperation and social order can emerge without coercion.

Mapping Poverty Hotspots and Infrastructure Deficits in Ghana: A Spatial Analysis of Household Welfare Using GLSS 7

Using GLSS 7 and spatial data, this study reveals that poverty in Ghana is heavily concentrated in the northern regions and is significantly driven by deficits in road networks and access to health facilities, thereby advocating for targeted infrastructure investments to bridge the north-south welfare divide.
