Input-Output Analysis

From Open Risk Manual


Input-Output Analysis is a subfield of economic analysis that is characterized by its employing models of economic systems as networks of exchange of goods and services between broadly defined economic sectors. The approach was first introduced by Leontief.[1]

The analysis tracks the interdependence among various producing and consuming sectors of an economy. Specifically it measures the relationship between a given set of demands for final goods and services and the inputs required to satisfy those demands.[2]


Input-output analysis aims to answer economic questions such as: what level of output X is required by industrial sectors that are interacting in complex supply chains if a specific Final Demand vector is to be produced.
