input-output analysis


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.

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.
While the CGE approach might be called a flexible-price model, another approach is a fixed-price input-output model. One such example is the IMPLAN model (IMPLAN, 2011), which has been used to quantify impacts of many USDA programs (Peters, 2014; Golden et al., 2016).
This paper builds continuous multisectoral dynamic input-output analysis model and discusses optimal strategy design problems on the basis of Leontief dynamic input-output model. Considering that there exist fast production process and slow production process during the course of social production development, it constructs singularly perturbed bilinear dynamic input-output analysis model.
If you want to get a glimpse of the environmental impacts of any one product or business practice, you need an input-output model for several global regions involving thousands of variables.
In our MPC study, we adopted a data-driven modeling approach and applied system identification methods to obtain the input-output model parameters for building thermal zones.
The core of Potron's economic model, which he first set out in 1911, consists of a general disaggregated input-output model which involves a finite number of goods, of social groups, and of different types of labour.
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.
This paper deals with proposal of the NARX recurrent neural network as the nonlinear input-output model of the nonlinear time varying system--the laboratory model AMIRA DR300.
The next article, "Multipliers of the Peruvian Economy 2002", presents an application of the input-output model to estimate the multiplier effects of investments and exports on the Peruvian economy developed by Torres-Zorrilla.
