Data Sources and Citation Metrics
The 5th edition of the Research.com Best Economics and Finance Scientists in Singapore Ranking is primarily constructed using bibliometric data harvested from prominent and reputable sources, most notably OpenAlex and CrossRef, supplemented by multiple additional data repositories. The citation-based metrics that underpin the ranking were systematically collected on January 12, 2026, ensuring the most current and comprehensive data set available at the time of compilation. A key metric employed in determining each scientist's position within the ranking is the D-index (Discipline H-index), which specifically includes papers and citation counts exclusive to the discipline under examination, in this case, Economics and Finance.
Scope of Research and Selection Criteria
The scope of the ranking is expansive, having initially examined a total of 279,971 scientist profiles identified from a diverse array of bibliometric data across all scientific disciplines. Within this broad dataset, 13 scientists specializing in Economics and Finance were specifically identified for further evaluation.
To qualify for inclusion in the ranking, a researcher must meet the following criteria:
- A minimum D-index threshold of 30, ensuring significant disciplinary impact.
- A majority of their tier publications must be within the field of Economics and Finance, affirming their specialty focus.
- Consideration of awards and notable achievements specifically relevant to Economics and Finance.
The D-index threshold is dynamically set as increments of 10, reflecting the total number of scholars estimated for each discipline while guaranteeing that the top 1% of leading scholars are incorporated into the list. Additionally, a proximity criterion mandates that the difference between a scientist’s general H-index and their D-index does not exceed 30%, ensuring relevance and consistency between overall and discipline-specific impact.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the Research.com team implements rigorous manual verification and cross-correlation processes. Each scientist’s profile undergoes thorough validation against publications documented in a variety of trustworthy academic sources.
While the number of publications in leading journals and conference proceedings does not directly contribute to a scientist’s ranking position, it is regarded as a valuable secondary signal of research contribution within the discipline.
The ranking position is primarily established based on each researcher’s D-index, derived from data collected from OpenAlex and CrossRef—currently the most prominent and widely recognized bibliometric databases accessible to the global research community.
