Input-Output Accounts


1. Introduction:   The System includes an integrated set of supply and use tables or matrices as well as symmetric input output tables or matrices. They provide a detailed analysis of the process of production and use of products and the income generated in that production. ‘Symmetric’ means there are same classifications (groups of products) which are used in both rows and columns. The term symmetric is used for input output tables, when SUT has same number as rows and columns it is called square SUT. The input output tables serves a coordinating framework for economic statistics, both conceptually for ensuring the consistency of the definitions and classifications used and as an accounting framework for ensuring the numerical consistency of data drawn from different sources. As an analytical tool, input-output data provides macro-economic models linking final demand and products output levels. Input output analysis also serves a number of other analytical uses.

Static input output analysis can be studied independently of the system of national accounts as well. This section will first introduce static input-output analysis as inter-industry analysis assuming that one industry produces one good (homogeneity assumption) and explain the related models and applications. Then the real economic life situation will be considered where an industry produces products and by-products and the compilation of symmetric input output tables will be described. It may be remembered that supply and use tables represent intermediate stage between basic statistic and symmetric input output tables.

Static Input Output Analysis
The productive process of a complete economic system can be described in a unified way through inter-industry (or...
