REPEC - RESEARCH PAPERS IN ECONOMICS (RePEc) RePEc (Research Papers in Economics) is a joint initiative of economists from 44 countries, consisting of discussion papers (grey literature), journal articles and economic software tools. A large proportion is freely accessible or contains links to full texts. In addition, there is information about some 5,000 authors (contact address, publication directories) and 8,000 institutions (research institutes, faculties, etc.). (Previously: Economists Online (EO): to be found here since 2014.) The RePEc data is searchable via various search options, including IDEAS (entire collection), WoPEc (discussion papers in full text), EDIRC (institutions) and BibEc (bibliography of the not freely accessible discussion papers).
