The files in this series contain correspondence, reports, and publications documenting the economic analysis and research work of the Economics and Research Staff (ERS) and the two ERS departments: the Economic Analysis and Projections Department (EPD) and the Development Research Department (DRD). Most of the correspondence was sent or received by the Director of EPD and by staff in the EPD divisions, but there is some correspondence of the Vice President of ERS and of the DRD staff. The correspondence concerns commodity price forecasts, economic and social data generated by ERS, international trade, external debt of developing nations, and comments on drafts of the World Development Report (WDR) and on background papers prepared for the WDR. Specific documents and publications include: Back-to-Office Reports from ERS staff attending conferences or undertaking missions to analyze a specific industry; copies of the commodity handbooks issued by the Commodities and Export Projections Division (EPDCE); quarterly reviews of commodity markets; publications on commodities from the Commodity Studies and Projections Division (EPDCS); copies of the 1984 - 1986 annual reports on the World Bank Research Program; the EPD's User's Guide on World Bank Trade Data System issued in October 1985; and a June 1984 draft of the Pfeffermann Committee's Report on Economy-Wide Modelling in the Bank.
