This series contains copies of PAC Memoranda, summaries of meetings, and other records of the Planning Assumptions Committee (PAC) and related records of the Economic Analysis and Projections Department (EPD) and later of the International Economic Analysis and Prospects Division (IECAP), the two units that maintained these records.

Originally formed in the early 1970s as the Deflator Committee, the Committee approved the deflator projections to be used in Bank financial planning and in project appraisals. Late in 1980, the name was changed to Planning Assumptions Committee, and its role was broadened to cover a wide range of key indicators of change in the global environment. By establishing common planning assumptions about the world economy, the Committee ensured that the various parts of the Bank used the same projections for economic and sector work, project analysis, financial and budget analysis, and the World Development Report. The Global Analysis Division (EPDGL) of EPD and later the International Economic Analysis and Prospects Division (IECAP) of IEC prepared the background analysis and projections for PAC. This series includes memoranda from those two units transmitting projections data to the PAC chairman. That data was incorporated into the PAC Memoranda which were issued twice a year, in the spring and the fall, to units throughout the Bank. By the late 1980s, these memoranda were issued directly by IECAP, through the Director of the International Economics Department (IECDR) as PlanningAssumptions for Major Macroeconomic Indicators and Financial Indicators. In addition to the official PAC memoranda, there are intra EPD and IEC memoranda documenting the process of compiling the planning data.
