Many authors in economics and finance circulate their work in progress as working papers, which allows for discussion and comment before they are submitted for publication.
Working papers have generally not been peer-reviewed and are frequently revised before publication as a finished article. NBER and SSRN will link to a published version, when available.
Many Centers on campus publish working papers. Some host them at SSRN, while others maintain a local collection. Use these links to browse the latest papers.
