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.

Corporate Dividend Policy under Common Ownership: Examining Dividend Similarity Using HypergraphsHarada Haruki (原田春貴)Using data on 4,291 companies covering 43,800 firm-years from 2005 to 2023, this study represents common-ownership relationships with hypergraphs and examines similarity in companies’ dividends (DOE). It analyzes the relationship between common ownership and dividend similarity using hypergraphs, which can represent investors holding multiple companies simultaneously, and the Zhou and HTV statistics, rather than conventional pairwise analysis.

Consumer Preferences for Domestic Ingredients in Japan’s Ready-to-Eat Meals and Dining-Out Market: A Best-Worst Scaling AnalysisConsumer preferences for domestically produced ingredients in Japan’s ready-to-eat meals and dining out: a best–worst scaling analysisGuanjun Li · Kohei Yagi · Ting ChenAn online survey of Japanese consumers conducted in 2024 used best-worst scaling to analyze the relative importance of 11 food attributes for ready-to-eat meals (786 respondents) and dining out (771 respondents). Taste, price and safety ranked highest, while domestic ingredients ranked fifth in both settings. The findings indicate that domestic ingredients are a meaningful consideration, but rank relatively low unless linked to specific benefits such as taste or safety.

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.

Conflictual and Cooperative Behavior and Voters’ Perceptions of Parties’ Political Positions: A Conjoint Experiment in JapanConfrontation, cooperation, and perceived ideology: experimental research on voters’ perceived positions and political competitionHideo Ishima · Keisuke ASHITANI · Ashu OkadaA conjoint experiment of Japanese voters examined how the politeness and aggressiveness of politicians’ statements, as well as their cooperative behavior with other parties, affect perceptions of a party’s political position. The analysis distinguished among multiple dimensions, including left–right, liberal–conservative, and progressive–conservative, and showed that voters infer political positions from conflictual and cooperative behavior.

Information Useful for Decision-Making in Partially Observed Production NetworksDecision-Relevant Information in Partially Observed Production NetworksShaowen Luo · Kwok Ping Tsang · Zichao YangUsing partial identification and maximum regret, the analysis examines how reliably monitoring targets for supply shocks can be selected and exposure thresholds determined when only part of the transaction flows in a production network can be observed. In Japan’s interregional input-output tables, adding 1,606 statistics, equivalent to approximately half of the total disclosure cost, reduced the average loss relative to the 2005 benchmark to 0.07 points, while maximum regret across all networks consistent with the observations was 4.834 points.

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.

Did sanctions on Russia backfire? The macroeconomic effects of support for Ukraine on prices and economic growth across countriesDo Sanctions Backfire? New Evidence on the Macroeconomic Effects of Supporting UkraineVicente Rios · Izaskun Barba · Lisa GianmoenaUsing data from 129 countries over 2000–2024, the study distinguishes between the 2014 sanctions and the 2022 escalation, estimating the difference between sanctions-participating countries and their counterfactuals. From 2022 onward, the gap in consumer prices in participating countries widened by 0.072 log points, or approximately 7.5%, relative to 2019–2021, while no robust evidence was found of losses in real GDP per capita.

Applied to 2019–2024 data for Kernel Holding, MHP and Astarta, the framework showed that FSI fell to 1.9–2.7 in 2022 before recovering in 2023–2024, with the industry’s average FSI reaching 3.3.

What Drives Changes in Central Bank Foreign-Exchange Reserve Currency Composition: An Analysis of Economic, Trade and Sanctions Factors in the United States, Euro Area and ChinaDynamics of the Currency Composition of Central Bank ReservesDeborah Gefang · Stephen G. Hall · George S. TavlasUsing foreign-exchange reserve currency shares for 53 countries and regions from 1999 to 2023, the study applies a seemingly unrelated regression (SUR) model incorporating the constraint that the total share of 8 currency categories equals 100%. Reserve composition shows strong persistence and interdependence among currencies. After adding year fixed effects, trade relationships and sanctions remain particularly robust associated factors.
