Evaluating the possibilities for exchanging regional input - output coefficients
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.
