What RePEc offers to Twitter users

January 31, 2019

Twitter is a social media forum that facilitates discussions on all sorts of topics, including economics. Within this large universe, it may be difficult for economists to find who to follow and who to converse with. Indeed, some very interesting conversation do take place, and contrarily to popular opinion, Twitter can be a very civil and professional environment.

To help with this, RePEc has taken various initiatives:


  1. All NEP reports, which disseminate new working papers in about 100 fields of economics, are available through email, RSS and Twitter. Visit the NEP homepage for a listing, or if you just want the Twitter accounts, see a compilation here.
  2. RePEc provides directories of economists on Twitter. These directories are assembled by country and by field (following the NEP model). In addition, there is a directory of female economists, and several for different types of institutions (like central banks or liberal arts colleges). The big directory is available here, to see the others click on the “more listings” tab. Another tab explains how to get listed.
  3. All members of the above directories with public Twitter accounts are also automatically members of the corresponding Twitter lists. This allows to easily follow the activity of the economists in a particular country or field. The Twitter lists are linked above each of the directories.
  4. IDEAS allows easily quoting on Twitter. If you click on the Twitter icon on any abstract page, this creates a Twitter post with the title of the paper and an image containing its abstract. When discussing research on Twitter, it is generally a good idea to link to a RePEc page instead of directly to the publisher. In case the reader cannot access this document, RePEc may offer alternatives. See this RePEc Blog post for more details.
  5. Finally, RePEc has a few Twitter accounts of its own, RePEc_org and repecCitEc.


RePEc in 2018: A Year in Review

January 3, 2019

In its 22nd year of operation, RePEc is still growing healthily. Almost a quarter million new research items have been added in the course of the year, and we should be surpassing 3 millions sometime in 2019. In part, this growth was made possible thanks to newly participating archives, 61 of them, putting us over 2000 RePEc archives. We collect traffic statistics from four RePEc services, EconPapers, IDEAS, NEP and Socionet. They reported for the year 104,603,252 full-text downloads and 420,281,818 abstract views (after considerable vetting, well over 90% of traffic is from robots). This is not counting all the other services using the data made available by RePEc. And RePEc has also performed various upgrades to its services:


  • IDEAS and EDIRC have being completely redesigned.
  • MyIDEAS now has the ability to send weekly email digests for what users track.
  • Rankings saw various additions, principally those tracking only the last 10 years of publication and the 10 best authors per institution.
  • CitEc has improved citation extraction and increased its scope.
  • Various behind the scenes improvement, in particular for NEP.

There is much more to come in 2019. Watch out for news, or even better, participate as a volunteer!


RePEc in December 2018

January 3, 2019

RePEc saw good traffic for a month of December, with 402,760 file downloads and 2,055,763 abstract views. We welcomed a few new archives: University of Cambridge (V), Indian Institute for Geo Economic Studies, University of Warwick (II), Better Advances Press, Red Investigadores de Economía, South Asia Watch on Trade, Economics and Environment (SAWTEE), Global Social Sciences Review (GSSR). And we reached the following milestones:

1,200,000 new paper announcements through NEP
100,000 user-contributed changes to the RePEc Genealogy


RePEc in November 2018

December 4, 2018

Last month, we counted 497,856 file downloads and 2,031,700 abstract views on reporting RePEc services. We weclomed a good bunch of new RePEc archives: Financial Research Institute (Moscow), Budapest Business School, Economic Research Institute for ASEAN and East Asia (ERIA), Athens Institute for Education and Research, African Finance and Economic Association, Institut national d’études démographiques (INED), Red Investigadores de Economía (Colombia). We also added a small feature that allows to correct how we infer their gender. This can be found on the ranking analysis link they get in their monthly email. And finally we reached one milestone:

700,000 cited articles


Should IDEAS add reader-contributed user notes to abstract pages?

November 28, 2018

RePEc is always looking for ways to offer more useful services to the Economics community. One suggestion that we receive on a regular basis is to make is possible to add public comments, “user notes”, about the papers disseminated by RePEc. In this blog post, we offer a proposal for such a feature on IDEAS, with proposed rules and a poll to see whether the Economics community would be interested in this new feature.

This should give the opportunity to readers of the papers to offer their comments, for authors to provide clarifications, for conference discussants to provide their thoughts to a wider audience, and even for referees to make public their reports, if they wish so.

Rules of user notes on IDEAS


  1. A RePEc user account (RePEc Author Service) with clear identification is necessary to post a user note.
  2. There is a delay of a day between the creation of an account and the privilege of posting.
  3. Posts retain the name of the poster even after deletion of the account.
  4. Posts should remain professional and on topic. Readers can report abuses to moderators (no registration required). The text of moderated posts will become invisible, with poster name still visible and reason for moderation declared. Posters can appeal moderation decisions.
  5. Registered authors and previous posters in a thread will be alerted about a new user note. Authors have the opportunity to opt out of alerts for the associated paper or all their papers.
  6. A bulletin board is available to see new user notes. Boards are also available by subfield (if no subfield can be determined automatically by JEL codes or NEP reports, the first poster can set the subfield).
  7. A user note posted for one version of a paper will be visible for all versions of that paper.
  8. User notes are in plain text, with no attachments and no links, of at most 5,000 characters. Posters can thread several posts, though.
  9. There will be no counting of points, likes, upvotes, scores, or other games associates with this.
  10. This set of rules can change as experience warrants, after consultation with users.

This poll is open until 26 December 2018, midnight CST.

Addendum: The poll is now closed. We will work over the next months to put the user-note feature in place.


RePEc in October 2018

November 8, 2018

This was a busy month at RePEc. Not because of new archives, because just two new ones joined: Revista Lumina and Universitas Islam Indonesia. However, a lot of material was added and we enjoyed good growth in traffic, with 496,854 file downloads and 1,885,141 abstract views from reporting RePEc services. A minor innovation, female economists are now identified from their names with NamSor. And we passed the following milestones in October:

1,800,000 indexed journal articles
25,000 books available online


How does RePEc promote Open Access?

October 25, 2018

This week is Open Access Week, and this gives us the opportunity to highlight how RePEc has been promoting open access to economic literature since 1997 (and since 1992 with its predecessor projects). We want to distinguish here two ways research is open in economics: through pre-prints and through open access journals.

Pre-prints

Economics has a long tradition of pre-prints that predates the web. Usually called working papers or discussion papers, they have become popular because publication delays are very long in economics (measured in years). The origin of RePEc lies in making the dissemination of those pre-prints more efficient by providing central services for their discovery. Before, it was very difficult for those outside existing top institutions to know what the current frontier of research was. As is still valid now, publication in journals was really a historical record of where the research frontier was a few years earlier. Now, RePEc has records for over 800,000 pre-prints and disseminates them through web sites, mailing lists, RSS feeds and Twitter. They are also included in the citation analysis and they are indeed cited on a level field with journal articles. In fact, RePEc does not privilege journal articles over pre-prints, yet working papers are downloaded seven more times than the corresponding articles.

For those who stumble upon a journal article in a RePEc site, the alternative version as a pre-print is offered when available. This is particularly useful when the journal is gated: this allows the reader without a subscription to still have a read of the full paper. Sometimes it is not the final version, and sometimes it is even a more complete version as the editorial process may have required cuts. Such links from article to pre-print are particularly frequent for the most cited works.

Open access journals

RePEc is also indexing journal articles, and this includes the open access ones. Typically, they are noted with a special notice indicating that the full text can be downloaded freely. In addition, gated journals are not privileged in any way over open access ones: RePEc invites all journals to be indexed, as long as they are willing to follow our instructions. This allows small independent journals to get the same opportunity as journals from the largest commercial publishers to be searched and found on RePEc sites. In fact, free downloads does lead to more frequent downloads.
