input-output analysis

or

interindustry analysis

the study and empirical measurement of the structural interrelationships between PRODUCTION sectors within an economy. The technique was devised by Wassily Leontief (1906-) to measure the factor input required by different industries to achieve a given OUTPUT. A particular sector of the economy requires inputs from other sectors, be it raw materials, intermediate goods and services, or labour, in order to produce output. The interdependence between industries, or sectors, is not linear but complex. That is, one sector does not produce, say, coal for other sectors independent of the requirements of the coal industry for inputs from other sectors. For the mining sector, coal is an output. But coal is an input for the electricity industry. By the same token, the coal industry requires inputs (including electricity) in order to produce the coal. The complexity of an economy can be gauged from this simple example. See VERTICAL INTEGRATION, INDICATIVE PLANNING, GENERAL EQUILIBRIUM ANALYSIS.

The matrix is [(I-A).sup.-1] "Leontief's Inverse matrix", and is fundamental for the input-output analysis. The values in this matrix describe the influence of the exogenous change of the final demand on the total production.
Otro signo de salud y vitalidad de la investigacion en el tema es, sin duda, la aparicion de dos volumenes compilados por Dietzenbacher y Lahr: Input-Output Analysis: Frontiers and Extensions en 2001 y Wassily Leontief and Input-Output Economics en 2004; ambos suman 42 capitulos, que contienen estudios de frontera realizados por 52 investigadores.

There, he wrote his dissertation under the guidance of Wassily Leontieff, pioneer of input-output analysis. Professor Erdilek quickly recognized the limitations of the input-output technique for the question of global resource exhaustion, which some wanted to apply in the 1970s.
However, based on the input-output analysis, Ruiz-Napoles (2004) finds that the share of total employment generated by exports between 1980 and 2000 has actually increased.
He believed in the possibility of obtaining the relevant data for setting up the input-output matrices and calculating the unknowns of his economic model and indeed made some attempts at applied input-output analysis. In one of his papers, he advocated Taylorism as a means to enhance labour productivity (and also because the discipline it imposed on the workers would help them to develop Christian virtues).
Clusters methodologies also differ in their use of techniques: (1) input-output analysis, (2) graph analysis, (3) correspondence analysis, and (4) the qualitative case study approach along the lines of the Porter studies conducted in various countries.
Energy input-output analysis is usually used to evaluate the efficiency and environmental impacts of production systems [10].
