This paper presents a correction of the RAS method (CRAS) that uses cell variation distributions calculated from multiple matrices of different periods or different regions. After the solution of the regular RAS, an additional optimization problem is solved that produces the most likely cell‐corrections to the regular RAS solution. To test the behavior of CRAS, several simulations with a time series of input–output tables for The Netherlands for 1968–1986 are made. They show that—in situations of structural change—applying CRAS improves the regular RAS estimate. The method will also be applicable to traffic, trade, and migration matrices.

Model specification errors result from the use of domestic environmental and domestic technology coefficients to estimate emissions or resources that are embodied in international trade. For $\text{ CO }_{2}$ footprints, unacceptably large overestimations arise from using domestic emission coefficients, which are only partly canceled out by using domestic technology coefficients. For water use footprints both specification errors are smaller, but hardly cancel out. Sectoral aggregation errors occur when combining the 129 EXIOPOL industries to 59 EU industries and 10 broad sectors. The latter aggregation creates the largest errors. Spatial aggregation errors arise from combining 43 individual EXIOPOL countries in four broad regions and “the rest of the world”. Substantial, unacceptable errors occur again, now especially in relation to water use.
