In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. [1] Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
Wassily Wassilyevich Leontief (Russian: Васи́лий Васи́льевич Лео́нтьев; August 5, 1905 – February 5, 1999), was a Soviet-American economist known for his research on input–output analysis and how changes in one economic sector may affect other sectors.
The concept of productive matrix was developed by the economist Wassily Leontief (Nobel Prize in Economics in 1973) in order to model and analyze the relations between the different sectors of an economy. [1] The interdependency linkages between the latter can be examined by the input-output model with empirical data.
Input-Output models, developed by Wassily Leontief, take advantage of linear programming and matrices by dividing the economy into interdependent sectors that produce products for both themselves and other sectors; the production in one sector relies in the input of goods from another. [14]
Two input Leontief Production Function with isoquants. In economics, the Leontief production function or fixed proportions production function is a production function that implies the factors of production which will be used in fixed (technologically predetermined) proportions, as there is no substitutability between factors.
The International Input–Output Association (IIOA) is a scientific, nonprofit, membership organization to facilitate development of input–output analysis in economics and interdisciplinary areas of inquiry. Input–output models and analysis in economics were developed by Nobel Laureate Wassily Leontief. Leontief worked from transactions ...
She holds a master's degree in public administration and economics from Syracuse University and a PhD in economics from Harvard University, where she was in charge of the regional work at the Harvard Economic Research Project.

The Waste Input-Output (WIO) model is an innovative extension of the environmentally extended input-output (EEIO) model. It enhances the traditional Input-Output (IO) model by incorporating physical waste flows generated and treated alongside monetary flows of products and services. [1] In a WIO model, each waste flow is traced from its ...
