Early-Career Funding Allocation and Cumulative Advantage in Scientific Careers: A Mathematical Model and Empirical AnalysisEarly-Career Research Funding and Cumulative Advantage in Scientific Careers: A Mathematical Model and Empirical AnalysisYuhei YamaguchiThe study presents a cumulative advantage model showing that receiving research funding early in one’s career leads to a research-performance advantage that continues to widen, even after accounting for differences in talent and graduate school attended. Using panel data on approximately 40,000 Japanese researchers across 8 fields, it reports that the advantage enjoyed by initial fellowship recipients is statistically significant and continues to grow more than 10 years later.

Wives in Management in Japan and Husbands’ Well-Being: An Analysis of Gender Asymmetry Within HouseholdsWives’ Managerial Employment and Husbands’ Well-Being: Evidence of Intra-household Asymmetry in JapanKazuma SatoUsing Japanese panel data, the study analyzes the association between having a spouse in a managerial position and one’s own well-being. Husbands reported lower well-being in households where the wife was a manager, while no consistent association was found between the husband being a manager and the wife’s well-being. This negative association was stronger in households where the wife was the primary breadwinner, households where the husband had a lower level of educational attainment, and couples where only the wife was a manager.

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.

Decomposing Audience Preferences and Creative Effects in Visual Content Using Image and Language Models and Panel Causal InferenceDIRECT: Decomposing Audience Preference and Creative Effect in Visual Content AnalyticsYizhi Liu · Balaji Padmanabhan · Siva ViswanathanUsing 232,088 sponsored beauty posts on Instagram, the study separates “audience preferences,” driven by differences between creators, from “creative effects,” which reflect responses to deviations from a given creator’s usual style. It does so using CLIP, the Mundlak decomposition, and double machine learning. The signs of the two effects diverged for 4 of 11 visual attributes. Recommendations based on pooled coefficients missed up to 31% of the achievable increase in engagement compared with recommendations based on DIRECT creative effects.

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.

The Dynamic Trade-offs of Dual-Class Shares: Founder Incentives and Private Benefits of ControlThe Dynamic Trade-Off of Dual-Class SharesHyunseob Kim · Doron Levit · Roni MichaelyUsing a 1971–2022 panel of U.S. dual-class companies, the study finds that firm value, measured by Tobin’s q, rises by 0.21 in the year following a change from single-class to dual-class shares, while the valuation gap nearly disappears after about 10 years. By contrast, innovation, measured by patent citations, increases persistently. In mature companies, private benefits of control expand, making investment less responsive to opportunities.

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.

Principal Component Analysis for Data Containing a Mix of Stationary and Nonstationary SeriesPrincipal Component Analysis for a Mix of Stationary and Nonstationary VariablesJames D. Hamilton · Xinwei Ma · Jin XiWe propose a method that applies PCA to the OLS residuals from medium-term-ahead forecasts for each series, without first determining whether the series are stationary or nonstationary or transforming them individually. Applied to FRED-MD, the method showed forecasting power comparable to conventional PCA. Its agreement rate with NBER recession periods was 98% for 24-month-ahead forecast residuals, compared with 65% for the conventional series.

A method for estimating the structural parameters of a marketing mix model from time-series data generated by geo experimentsStructural Estimation of Marketing Mix Model Parameters from Geo-ExperimentsNiklas HeuschWe proposed a method that simultaneously estimates the persistence of advertising effects (adstock), diminishing returns (saturation), and effectiveness using the difference in outcomes between treatment and control regions in geo experiments. In synthetic data, conventional observational MMM overestimated ROAS at 10.61x, compared with the true ROAS of 4.20x, whereas the proposed method accurately recovered the true value, estimating 4.31x with 2 experiments and 4.14x with 4 experiments.

Synthetic Benchmark Dataset for Validating Marketing Mix Models with Endogenous Marketing SpendA Synthetic Benchmark Dataset with Endogenous Marketing Spend for Validating Marketing Mix ModelsNiklas HeuschWe constructed a synthetic retail dataset covering 156 weeks and 3 channels, with 4 adjustment mechanisms under which advertising spend responds to sales, planned promotions, seasonality, and past performance. The dataset records the true causal decomposition of sales for each week, allowing marketing mix models and geo experiments based solely on observational data to be compared with the ground truth.

Women's Economic Rights under Libyan Family Law: An Islamic Law Analysis of Mahr, Maintenance, Divorce, Housing, Custody Costs and Child SupportWomen's Financial Rights in Libyan Family Law: An Islamic Legal Analysis of Mahr, Maintenance, Divorce, Housing, Custody, and Child Support<b></b>Naser Abdulghani · Youcha TouréThis study provides a doctrinal analysis of women's economic rights under Libya's 1984 Marriage and Divorce Law and the amending laws of 1991 and 1994. It concludes that, although the legal framework broadly recognizes women's rights before and after marriage in accordance with Islamic law, ambiguities remain concerning the calculation of maintenance, enforcement of housing rights, custody costs, compensation, and adjustments to amounts based on economic circumstances.

Human Capital Disruptions and Idiosyncratic Risk Disclosed in Earnings CallsDisclosed Human-Capital Disruption and Firm-Specific RiskAng ZhangA context-dependent model extracted human capital disruptions, including hiring difficulties, employee turnover, rising wages, workforce restructuring and management changes, from earnings call transcripts. In annual data, a 1-standard-deviation increase in the measure was associated with a 0.55-percentage-point increase in idiosyncratic volatility, a 0.58-percentage-point increase in downside deviation and a 0.46-percentage-point deterioration in the worst monthly return.
