This manual provides documentation for users of the GFPM. The GFPM is a microcomputer-based economic projection model. The version of the GFPM described here projects the consumption, production, manufacturing capacity, imports, exports, and prices of 14 commodity groups (ranging from fuelwood to newsprint) in 180 countries, for the period 1994-2010. For every year, the model computes the demand, supply, trade and prices that clear markets for every commodity and country. Thus insures a global balance between final product requirements and raw material availability world-wide. Year-to-year changes reflect economic growth, changes in raw material supply, and technological change. This manual has a detailed description of the computer software needed to run the GFPM, of the steps in preparing the input data and of the procedures used to run existing or modified GFPM models. It contains a complete directory of the GFPM computer files and of its country and commodity codes, together with practical notes on how to use the GFPM, change its assumptions, and obtain new projections.
