Research by EfD researchers and their associates appears initially in the EfD Discussion paper (DP) series. The discussion papers are circulated to the scientific community and interested public worldwide and are available free of charge. The DPs are currently edited by Professor Peter Berck of the University of California Berkeley and Dr. Yonas Alem of the University of Gothenburg. Professional editorial service is provided by International Academic Editorial Services. Submissions for the EfD DP series should be done by members of the EfD network only.
