ABSTRACT
The preparation of an input–output transactions table means, in effect, attempting to account in a disaggregated form for virtually all of the transactions which occur in an economy in a given time period. Most regional input–output analysts in the United States and the United Kingdom appear to have faced similar problems with respect to the availability of suitable data and research resources. If any consensus in the matter of survey and non-survey approaches were to emerge from input–output analysts, it would probably be that the survey approach is the most attractive both theoretically and intuitively. The 1963 survey-based table for Washington state was used by Czamanski and Malizia to test the RAS method, and by Schaffer and Chu to evaluate the major variations of the location quotient and commodity balance approaches. The use of the RAS technique as a single-step approach to the derivation of input–output coefficients has been examined by a number of analysts.
