On January 12, 2026, the relevant bibliometric data used to construct the citation-based metrics were meticulously collected. The ranking methodology prioritizes the D-index (Discipline H-index), a refined bibliometric metric tailored to appraise a researcher’s impact within a specific discipline. Unlike the classical H-index, the D-index exclusively incorporates papers and citations pertinent to the examined field—in this case, Economics and Finance—thereby ensuring disciplinary relevance in the evaluation of scientific influence.
Scope of Research and Qualification Criteria
The ranking scrutinized a total of 279,971 scientist profiles across all scientific disciplines extracted from a wide array of bibliometric sources. From this extensive dataset, 5 scientists specializing in Economics and Finance within Ghana were specifically identified and evaluated.
To qualify for inclusion, a scientist was required to possess a D-index of at least 30. Furthermore, a majority of their tier publications needed to be concentrated in Economics and Finance, reflecting focused scholarly contributions in the discipline. Additionally, consideration was given to the scientists’ awards and recognized achievements in the field, further validating the quality and impact of their work.
The D-index threshold for identifying top researchers is dynamically adjusted in increments of 10 according to the estimated total number of scholars within each discipline. This scaling ensures the inclusion of the top 1% of leading scientists while maintaining rigorous standards. An important consistency check mandates a proximity of 30% or less between a researcher’s general H-index and their disciplinary D-index, safeguarding coherence in their general and specialized research impact.
Verification and Validation Practices
The Research.com team fully acknowledges the limitations of raw bibliometric data as an absolute measure of scholarly output. Consequently, all scientist profiles included in the ranking underwent manual verification and were cross-correlated with publications indexed in a broad spectrum of trustworthy sources. This meticulous validation process enhances the credibility of the ranking and mitigates potential errors arising from data inconsistencies or author disambiguation challenges.
While the ranking position is primarily determined by the D-index calculated from information aggregated from OpenAlex and CrossRef—both widely respected bibliometric databases—the number of papers published in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s scholarly contributions within Economics and Finance. This additional context provides a more nuanced perspective on research excellence.
