 Current Uses of the RAS Technique: A Critical ReviewKaren R. Polenske Chapter 4 in Prices, Growth and Cycles, 1997, pp 58-88 from Palgrave Macmillan Abstract: Abstract Many analysts are using nonsurvey techniques to estimate national and regional input-output tables, interregional trade flows, and other types of economic data. Analysts’ extensive use of these techniques reflects the delicate compromise they must make between the cost of collecting actual data and the accuracy of the models with which they work. For adjusting and/or updating input-output tables, analysts most widely use the RAS procedure. Based upon the structure of a national or a different, but supposedly similarly structured, regional table, they employ the technique both to update national (regional) tables and to estimate regional tables. They use a base national (regional) table, A, and separately estimate marginal row (r) and columnand column (s) controls for the predicted year. They then iteratively adjust the flows in A first to sum to the respective rs and then to the respective ss until the new row and column totals in the new matrix are as close as designated to marginal (actual) totals.
