| Abstract: | The existence of problems which are peculiar to agricultural subsectors explains the presence of organisations associated with individual commodities or commodity groups. Modern developments in information systems can contribute to meeting organisations' information requirements, but it is necessary to design systems consistent with both the principles and techniques of economic analysis and the general methodology. Following the definition of a subsector, a review of the principles for information systems and the relevant economic concepts shows the formal equivalence of many basic ideas. Despite reservations which have been expressed about the current potential for quantitative techniques, an input/output approach could have an important role as a flexible component of subsector information systems. |
