RePEc disseminates research in economics, including working papers, journal articles, software components, author information, directory of institutions.
RePEc (Research Papers in Economics) is a collaborative effort of hundreds of volunteers in 58 countries and 35 U.S. states to enhance the dissemination of research in economics. The heart of the project is a decentralized database of working papers, journal articles and software components. Some RePEc material is freely available, but RePEc does not contain full-text journal articles; article links require subscription access. RePEc collaborates with EconLit to provide content from leading universities' working paper series to EconLit.
