Evaluating the Possibilities for Exchanging Regional Input—Output Coefficients

Environment and Planning A, 1977, vol. 9, issue 8, 927-944

Abstract: The RAS technique is used to explore the possibilities for utilizing survey-based input–output models developed for one state in another state. The sensitivity of the biproportional parameters are examined in the context of a simple coefficient exchange. Finally, survey-based, RAS-derived, and random-coefficient models are compared under varying conditions of changes in final demand. The results confirm the aggregate validity of the RAS technique but question its reliability on an industry-by-industry basis.
