Abstract

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 products to obtain square matrices, with the subsequent loss of information. This should not be case, as rectangular matrices can be directly used for modeling by the methods of generalized inversion. The aim of this working paper is to highlight that there is no need to elaborate symmetric input- output tables (SIOTs). After describing SIOT-building procedures using the product technology and the industry technology hypotheses, the paper presents an example that illustrates the different options available for economic analysis in the SUTs context.
