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.

Due to the relative simplicity of the Input-Output Model, the Leontief open model is generated under some assumptions, which can also be seen as providing the main limitations of the analysis (Schuschny, 2005):
Arguably, the input-output model derives its popularity from the clear intuition of its measures in the case of "snake" production systems where industries produce only one output and deliver to only one industry.
Typically, there are two types of building models that are used in MPC: 1) black-box input-output models such as ARX (Autoregressive model with eXogenous input), ARMAX (Autoregressive--moving-average model with eXogenous inputs), BJ (Box-Jenkins), OE (Output-Error), and state-space models and 2) grey-box models such as resistance and capacitance thermal networks that are based on a physical understanding of the building.
The construction expenditures with appropriate local purchase content and employment data were entered into the IMPLAN regional input-output model to obtain the direct, indirect and induced effects of jobs and construction expenditures.
The first application of an input-output model to the environment was undertaken by Leontief in 1970 in which he explained how the environmental externalities of economic activity can be incorporated into a standard input-output model.
