Input output techniques
This article is about the economic model. For the computer interface, see Input/output.
In economics, an input–output model is a quantitative economic technique that represents the interdependencies between different branches of a national economy or different regional economies. Wassily Leontief (1905–1999) is credited with developing this type of analysis and took the Nobel Prize in Economics for his development of this model.
The International Input-Output Association is dedicated to advancing knowledge in the field of input–output study, which includes "improvements in basic data, theoretical insights and modelling, and applications, both traditional and novel, of input-output techniques."
