Economic Institution Rankings at IDEAS

This file is part of IDEAS, which uses RePEc data

Top 5% Economic Institutions, as of July 2007

Number of Citations, Weighted by Recursive Impact Factor, Discounted by Citation Age

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 recursive discounted 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.
Self-Citations are excluded.
Each citation is discounted by its age in years (1/age).
Authors are attributed equally and fully to each institution they claimed to be affiliated with.
Only institutions listed in EDIRC are counted.
Authors affiliated with subentities of institutions listed in EDIRC are also counted in the latter.
Subentities of ranked institutions do not increment the rank count and have their rank listed in parentheses

This ranking is based on 3341 institutions with 13762 registered authors.

Same ranking by individual authors or countries and states. All institution rankings. More 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).
