The bibliometric data, used to devise the citation-based metrics for this ranking, were collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric which considers only publications and citation counts relevant to the specific discipline under examination—in this case, Economics and Finance. This approach ensures that the ranking accurately reflects contributions within the discipline without dilution from unrelated research output.
Scope of Research and Eligibility Criteria
The ranking evaluates a total of 279,971 scientist profiles aggregated from a variety of bibliometric data sources, spanning all scientific disciplines. Of these, 18 scientists specializing specifically in Economics and Finance within Japan were closely examined. To be eligible for inclusion, a scientist must have a D-index of at least 30 and a majority of their tier publications must be within the domain of Economics and Finance. Additionally, awards and notable achievements in the field were also taken into consideration as supplementary factors.
The D-index threshold for considering top researchers is methodically calibrated in increments of 10, depending on the total estimated number of scholars in each discipline. This ensures an equitable and scalable approach, while simultaneously guaranteeing that the top 1% of leading scholars are incorporated into the ranking. Furthermore, to maintain disciplinary relevance, a proximity limit of 30% or less between a researcher’s general H-index and their D-index is required for qualification.
Verification and Validation Process
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output and impact, the researchers behind this ranking undertook meticulous manual verification of all scientist profiles. This process involved cross-correlation against publications indexed across a wide range of trustworthy and authoritative sources to ensure accuracy and reliability.
While the count of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position within the Research.com ranking, it constitutes a valuable secondary indicator of a scientist’s scholarly contribution within a specific field. The final ranking placement is ultimately established using each scientist’s D-index derived from data compiled by OpenAlex and CrossRef.
