Discussion Papers

About the Discussion Papers

The researchers at DIW Berlin usually publish their research results in scientific journals. However, this process can take many months, depending on the circumstances. To help bridge this gap, DIW Berlin began publishing Discussion Papers in 1989. The Discussion Papers offer a preview of the latest, not-yet-published research results, and allow current research to make its way into current debate more quickly.

Notes for authors

For publication in the series of DIW discussion papers the following may be submitted: Papers by DIW employees, DIW research professors and directors, DIW research affiliates and guest scientists who have spent at least one week at DIW Berlin and thank DIW Berlin in a footnote.    
Papers submitted will be sent in electronic form to the head of the relevant department at DIW Berlin. It is checked by an internal referee procedure whether or not the paper is likely to be published in a refereed journal. A decision on publication will then be made on the basis of a referee report. Should a paper have already been accepted for a publication by a refereed SSCI magazine or have received an invitation to a re-submission in a first-class journal, it will appear immediately without a referee procedure.
