Over the past decade, the increasing power and reliability of microcomputers and the development of sophisticated soft ware designed specifically for use with them has led to significant changes in the way that socioeconomic data are collected and analyzed. The venue of the computations has shifted from off-site main frames, dependent on highly trained operators and significant capital investment in supporting equipment, to desk top and lap top computers, dependent only on the occasional avail ability of electricity. This means that it is now feasible to quickly transfer new statistical techniques between IFPRI and IFPRI’s collaborators in developing countries, that data manipulation costs of policy analysis have been substantially reduced, and that a new level of complexity and ac curacy is now possible in the collection and analysis of survey data in developing countries.

As with any new technology, however, there are substantial costs in time and money involved in learning the most efficient ways of using this new technology and then transmitting these lessons to others. This series, Microcomputers in Policy Research, represents IFPRI’s collective ongoing experience in adapting microcomputer technology for use in food policy analysis in developing countries. The papers in the series are primarily for the purpose of sharing these lessons with potential users in developing countries, although per sons and institutions in developed countries may also find them useful. The series is designed to provide hands- on methods for resolving statistical and data collection problems encountered in food policy research. In our opinion, examples provide the best and clearest form of instruction; therefore, examples—including actual software codes wherever relevant—are used extensively throughout this series.
