Input-output analysis is a technique developed for the study of interdependencies between sectors or industries of an economy.

It is based on a system of linear equations which describe the existing relations between the inputs (or means of production) and outputs (or products) of all sectors of an economy. The framework has proved very suc­cessful in applied economic research. Nowadays, input-output economics covers a very broad area of research. Good overviews of the literature can be found in the collection of articles edited by Kurz et al. (1998), in Miller and Blair’s (2009) textbook, and in Ten Raa (2005). The International Input-Output Association (IIOA), founded in 1988, is the main network of economists working in the field (www.iioa.org). It publishes the journal Economic Systems Research.
