The objectives, concepts and methods of input - output analysis

Abstract

This paper deals with the considerations which are at the basis of the structure of the input-output tables which may be developed on the basis of the SNA. Chapter II explains the theoretical link between input-output tables and the SNA. In chapter III, input-output theory and some of its applications are discussed. Chapter IV reviews a number of factors which can affect the stability of the input-output coefficients and the recommendations made in the SNA to eliminate some of these possible disturbances. The effect of each of the recommendations on the structure of the input-output tables is illustrated on the basis of a numerical example derived from the SNA - matrix (table 2.1 of the SNA). Chapter V indicates which consequences these recommendations have for the input-output techniques developed in chapter III.
