Analysis of Risk Information Disclosures by Japanese Companies Using a Structural Topic ModelContent analysis of risk information disclosures using a structural topic modelAikawa Nobuhiro (相川延弘) · Yoshida Mitsuo (吉田光男)Risk disclosures by 1,829 Japanese companies over the 10-year period from 2015 to 2024, collected from EDINET and other sources, were analyzed using a 10-topic structural topic model (STM). The analysis shows that the composition and concentration of risk disclosure topics changed following the 2019 disclosure system reforms, with the share of certain topics, particularly IT-related risks, increasing.

Has Japan’s Foreign-Exchange Intervention Been Effective? An Examination Using the Portfolio-Balance ApproachHas Japanese Intervention in the Foreign Exchange Market been Effective?Yutaka KuriharaThis study provides an empirical analysis of Japan’s foreign-exchange interventions since the 2000s, using the portfolio-balance approach and other methods. Although the interventions were effective in influencing the yen exchange rate, their effects lasted only a few days. The findings suggest that speculative sentiment may have a greater influence on trading than portfolio balance.

Monthly Measurement of the Geopolitical Opportunity Structure (GOS) in Taiwan and Japan: 2014–2019Supplementary Data and Measurement Appendix Geopolitical Opportunity Structure (GOS): Taiwan and Japan, 2014-2019Kenta NozakiCompiles monthly GOS data for Taiwan and Japan covering the 72 months from January 2014 through December 2019, examining how international factors and domestic politics relate to the trajectories of social policy. The 144 country-month aggregate observations are intended as diagnostic and corroborating material for comparative process tracing, rather than as independent causal inference.

Quadruple-Helix Multidisciplinary Participation and Persistent Fragmentation in the Philippine Innovation EcosystemQuadruple Helix Framework Evidence Indicates Broader Multisectoral Participation amid Persistent Fragmentation in the Philippine Innovation EcosystemRaly James Perez Custodio · Lianne Angelico C. Depante · Primo GarciaA qualitative meta-analysis of studies published in 2013–2018 and 2020–2025 compared collaboration structures among government, universities, industry and local communities in the Philippines. Across 11 post-policy cases, participation by industry and communities, formal coordination, and structural and functional integration expanded, raising the proportion of quadruple-helix (QHF) configurations from 20.0% to 45.5%. However, issues involving relational integration and fragmentation remained.

The Effect of Moral Framing of Workplace Dissatisfaction on the Manifestations of “Quiet Quitting”Disaffection at Work: Employee Responses to Job-Related InformationBeatrice Braut · Mariele Macaluso · Vincenzo MollisiA randomized online survey of 1,450 employees in Italy and France examined the causal effects of word clouds emphasizing social justice and workers’ rights on workplace responses. Social justice-oriented framing increased explicit feelings of withdrawal from work by approximately 9.2 percentage points, while reducing passive disengagement, such as withholding one’s opinions, by 4.8 to 6.2 percentage points. It had no statistically significant effect on intentions to change jobs or support for unions.

Governance of Companies Operating Through AI: The Limits of Siloed AI GovernanceGoverning the AI-mediated corporation: corporate governance and the limits of detached AI governanceKei NakagawaThis paper argues that corporate AI governance should cover not only AI models and datasets, but also the companies that fund, procure, deploy, monetize and can shut down AI. It examines the need to translate AI principles into corporate governance mechanisms, including boards, organizations and supply chains, with reference to corporate authority, allocation of profits, risk-bearing and distribution of harm, using 3 publicly documented cases.

Assessing the Factors Driving Solar Panel Adoption and Sustainable Economic Development in YemenEvaluating Technological Innovation for Sustainable Economic Development in an Emerging ContextSabariah Yaakub · Shahid Ali · Norazah Mohd SukıA questionnaire survey of 393 people in Taiz and Hodeida, Yemen, used PLS-SEM to analyze factors associated with solar panel adoption and sustainable development. The study reports that government energy policy, maintenance barriers, economic viability, and owner satisfaction are associated with environmental improvement, while good governance and economic incentives moderate the relationship between intentions to reduce resource consumption and solar power adoption.

The Relationship Between Foreign Aid and Corruption Control in Five East African Community Countries: A Panel Data AnalysisDoes Foreign Aid Reduce or Fuel Corruption? Evidence from Selected East African Community Member CountriesMohamed Hamdan Idrisa · Vicent StanslausUsing data for Burundi, Kenya, Rwanda, Tanzania, and Uganda from 2004 to 2025, the study estimates the relationship between foreign aid and corruption control using pooled OLS (POLS), fixed-effects, and random-effects models. In the robust estimates, the ODA coefficient was −0.168452 for the random-effects Model I and −0.176891 for the fixed-effects Model II, indicating that an increase in foreign aid is significantly associated with a decline in the corruption control indicator.

Does National Culture Affect Government Compliance with Constitutions? A Comparative Analysis of 115 CountriesCulture and constitutional complianceJerg Gutmann · Anna Lewczuk-Czerwińska · Jacek LewkowiczThis study analyzes the relationship between national culture and the extent to which governments actually comply with constitutional provisions across 115 countries. It generally finds, using OLS and instrumental-variable estimation, that constitutional compliance tends to be higher in more individualistic societies and lower in societies with larger Muslim populations. The effects of generalized morality, power distance, and long-term orientation were not robust.

Estimation and Inference for Fixed-T Dynamic Spatial Panel Models with Common ShocksFixed-$T$ Dynamic Spatial Panel Model with Common ShocksJushan Bai · Jesse Chieh ChenThis paper proposes a large-N, fixed-T spatial panel model that jointly accounts for observed regressors, spatial interactions, dynamic persistence, and heterogeneous common shocks. Spatially extended random loadings (SERL) and a block coordinate method enable estimation and inference without estimating factor loadings for each individual unit. In simulations, the resulting confidence intervals were generally close to their nominal coverage levels. Applied to female labor force participation rates across U.S. counties, the estimated coefficient on education ranged from 0.527 to 0.646, with education accounting for 71.8% to 82.4% of the historical increase.

Assessing the European Union’s 2030 Climate Target Through Deep-Learning Emissions ForecastsEurope's Climate Ambition Under Scrutiny: Evidence from Deep Learning Emission ProjectionsJacopo Ghirri · Carlos Rodriguez-Pardo · Lara Aleluia ReisUsing a variational autoencoder and deep learning, the study analyzed economic, energy, transport, land-use and other indicators for the EU27 from 2010 to 2023, and forecast sector-specific CO2 emissions through 2030 if current trends continue. EU27 emissions are projected to decline 13.2%, from 2.72 Gt in 2024 to 2.36 Gt in 2030, but this would fall short of the 36% reduction required under Fit for 55, resulting in an estimated shortfall of approximately 622 Mt.

Automated Electoral Reform Systems, National Security, and Democratic Sustainability in NigeriaAutomated Electoral Reform Systems, National Security, and Democratic Sustainability in Nigeria: Reassessing the Electoral Integrity NexusSabo Okonu · Hope Chinenyenwa Nwaigwe · Odo Christopher UbaUsing an analysis of academic literature and official sources covering Nigeria’s Fourth Republic from 1999 to 2023, this study examines the relationship between electoral integrity, national security, and democratic sustainability. While automation, including biometric identification, voter accreditation, and result-viewing systems, improved identity verification and the transparency of results, issues involving technical failures, cybersecurity, institutional capacity, and legal interpretation remained in the 2023 elections.
