Top Countries and States by Number of Distinct Works, Weighted by Number of Authors and Recursive Impact Factors, as of May 2026

What this page is about

This page is part of a larger set of rankings for research items, serials, authors and institutions made available on this site. A FAQ is available.

  • Only authors registered with the RePEc Author Service are considered.
  • Only works listed on RePEc and claimed as theirs by registered authors are counted.
  • Each work is weighted by its recursive impact factor.
  • Different versions of the same work published in different series or journals are counted only once, the version with the highest impact factor being considered.
  • The score of each work is divided by the number of authors.
  • Authors who are deceased or whose email address with RePEc is invalid are not counted, the latter under the assumption that they have moved or have died
  • There are 9321 institutions with 73501 registered authors evaluated for all the rankings

The data presented here are experimental. They are based on a sample of the research output in Economics and Finance. Only material catalogued in RePEc is considered. For any citation based criterion, only works that could be parsed by the CitEc project are considered. For any ranking of people, only those registered with the RePEc Author Service can be taken into account. And for rankings of institutions, only those listed in EDIRC and claimed as affiliation by the respective, registered authors can be measured. Thus, this list is by no means based on a complete sample. You can help making this more comprehensive by encouraging more publications to be listed (instructions) and more authors to register (form). For more details on the various rankings that are available as well for documentation, follow this link.
