Top Countries and States, Number of Citations, Weighted by Number of Authors and Simple Impact Factors, Discounted by Citation Age, as of April 2021

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.
  • Citations are determined from references of listed works. Both the cited and citing works have to be listed in RePEc. See CitEc for details on the citation extraction.
  • Each citation is weighted by its simple 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.
  • Self-Citations are excluded.
  • Each citation is discounted by its age in years (1/age).Authors with multiple affiliations are attributed to each according to the weights they have set to each in their profile, or by default according to a formula described here.
  • Only institutions listed in EDIRC are counted.
  • Institutions are then attributed to the country or state of their location.
  • Please note that rankings can depend on the number of registered authors in the respective institutions. Register at the RePEc Author Service to be counted.
  • There are 61933 registered authors evaluated for all the rankings.

The data presented here is experimental. It is based on a limited 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.
