International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT): Distributed Version 1.0

IMPACT—the International Model for Policy Analysis of Agricultural Commodities and Trade—was developed at IFPRI at the beginning of the 1990s. The next document presents the components of the IMPACT model, including a technical description that shows the equations and the sources of the data used in the model. A general overview of the countries/regions and commodities is given in Appendix 2, while the detailed definitions of the countries and regions are shown in Appendices 3 and 4. After a description of the commodities, in Appendix 5, a schematic overview of the integrated modeling framework is given in Appendix 6. A complete list of the research published using the IMPACT modeling framework is provided in Appendix 1, including reports for international organizations, such as the World Bank, the Asian Development Bank, the FAO, and national governments.
