Data Sources and Citation Metrics
The 5th edition of the Research.com Best Economics and Finance Scientists in Portugal Ranking is primarily based on comprehensive bibliometric data derived from OpenAlex and CrossRef, alongside multiple other reputable data sources. These platforms are widely recognized for their extensive and up-to-date coverage of scientific publications and citations. The citation-based metrics that underpin the ranking were collected on January 12, 2026, ensuring the most current reflection of scientific impact.
A key metric utilized in determining a scientist’s position in the ranking is the D-index (Discipline H-index), which specifically measures research output and citation impact within a given discipline. By focusing exclusively on papers and citations relevant to Economics and Finance, the D-index provides a more precise and discipline-centered assessment of scholarly influence.
Scope of Research and Ranking Criteria
The ranking’s scope encompasses a broad evaluation of 279,971 scientist profiles identified from diverse bibliometric sources across all academic disciplines. Of these, 16 scientists specializing in Economics and Finance were examined in detail. To qualify for inclusion, a researcher was required to have a D-index of at least 30, with the majority of their tiered publications concentrated in the Economics and Finance domain. Additionally, significant awards and field-specific achievements were considered as supplementary factors in the evaluation process.
The threshold for the D-index is calibrated in increments of 10 according to the estimated total number of scholars within each discipline. This mechanism ensures that the publication captures the top 1% of leading scholars in the field. Furthermore, to maintain consistency and relevance, there must be a proximity of 30% or less between a scientist’s overall H-index and their discipline-specific D-index.
Verification and Validation Practices
Understanding that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s contributions, the Research.com team implements rigorous manual verification processes. All scientist profiles were carefully reviewed and cross-referenced against publications documented in a wide array of trustworthy sources. This meticulous approach enhances the reliability and accuracy of the ranking.
While the number of papers published in prominent journals and conference proceedings does not directly affect ranking placement, it remains a valuable secondary indicator of a researcher’s impact within their specialty. The final ranking is determined based on each candidate’s D-index, derived from the trusted data collections of OpenAlex and CrossRef—the most prominent and established bibliometric databases accessible to the scientific community.
