Ca Non-survey Methods Substitute for Survey-based Models ? A Performance Analysis of Indirect Techniques of Estimating I-O Coefficients and Multipliers
The objective of this article is to evaluate performances of eight non-survey methods in reproducing a survey-based I-O model in a both partitive and holistic sense. In order to evaluate methods, a package of statistics is selected and applied. The main results of the analysis are as follows. The Purchases-only Location Quotient (PLQ) demonstrates to overcome all the others in reproducing survey-based I-O coefficients whereas the Flegg et al. Location Quotient (FLQ) performs better in estimating survey-based output multipliers. Overall, the non-survey methods examined produce better results in estimating multipliers rather than I-O coefficients. In any case, estimates are too far from the survey-based ones. For this reason, methods should not be used alone but integrated with all available exogenous information within hybrid procedures.
