An example of a subanalysis is presented to illustrate a how a technology can be expressed in linear programming terms, b the level of detail that is desired in the subanalyses, and c how a subanalysis may be used. The difficulties of, and the aids to, the building of an economy-wide model are discussed. An economy-wide process analysis model is compared with other economy-wide models. It also discusses what can and cannot be hoped for from an economy-wide process analysis.
