Among the many matrix updating techniques available, basic RAS and its extensions are the most popular. RAS is a biproportional adjustment method, consisting in reiterative multiplication of row and column elements of a base matrix by correction coefficients. This technique is almost invariably...

It is relatively common to use location quotients (LQ) in the elaboration of regional (or sub-national) input-output tables (IOT). In the application of this kind of methodology, there appear two simultaneous corrections of the intermediate consumption matrix (one by rows and another by...

In economic studies, optimal use of known information should be paramount. But this requirement is usually neglected in economic modeling based on supply-use tables (SUTs). In SUT format the number of products is higher than the number of industries, and the usual practice is to aggregate...

Estimating the impact of tourism on an economy means to estimate both benefits and costs associated with tourism. Without any doubt, tourism has a huge economic and social importance. However, the growth of tourism has been accompanied by significant drawbacks in terms of emission of greenhouse...

The average propagation length (APL) has been proposed as a measure of the fragmentation and sophistication of an economy. For a one-sector economy, we show that the APL is strictly proportional to the macro multiplier of that economy. The same holds for strong intra-industry linkages. Hence,...

This paper develops a method to consolidate national supply-use tables (SUTs) into a single supra-regional SUT. The method deals with mirror trade statistics problems, such as the different valuation of imports and exports, and it corrects for double-counting re-exports. The method is tested by...

The GRAS method as presented by Junius and Oosterhaven [Junius, T. and J. Oosterhaven (2003) The Solution of Updating or Regionalizing a Matrix with Both Positive and Negative Elements. <italic>Economic Systems Research</italic>, 15, 87-96] assumes that every row and every column of a matrix to be balanced has...
