| Abstract: | Summary The Austrian Input-Output Table for 1970 (32×32, current, purchaser prices) was estimated on the basis of the official 1964 table (55×55), using a slightly modified version ofC. Almon's rejuvenating procedure. This biproportional algorithm permits the introduction of information on intermediate deliveries for the target year as well as the explicit consideration of different degrees of reliability attached to this kind of information. In addition, an import matrix for 1970 was used to define lower boundaries for the elements of the updated Input-Output Table. The results of the updating procedure were tested for plausibility in successive steps and a number of restrictions was imposed on elements or sums of elements to ascertain a good updating performance.Besides methodological aspects of updating the article concentrates on statistical problems connected with the estimation of margins (gross production, value added and final demand by Input-Output sectors) and intermediate deliveries in Austria for 1970. |
