International Input-Output Association

The International Input-Output Association (IIOA) is a scientific, non-profit, membership organization founded in 1988. It is rooted in the field of input-output economics, developed by Nobel Laureate Wassily Leontief. Leontief started from the transactions among different industries, such as agriculture, manufacturing and services but at a far more detailed level and embedded in a macroeconomic framework. This is why this field is also known as interindustry economics.

The objective of IIOA is to facilitate further development of input-output economics and, more generally, of input-output analysis in related, interdisciplinary areas of inquiry. Such development includes theoretical advances and improved modeling; empirical applications of input-output models and techniques; and expanded compilation of input-output tables, matrices, and associated accounts, in both national statistical offices and other kinds of venues. Data collection and analysis are carried out at the local and regional levels, for individual countries, and for economies consisting of multiple interdependent regions including the countries comprising the world economy.

The IIOA grew out of an informal, world-wide network of economists, government officials, engineers, and managers with interests in the analysis of interdependency in economic and other kinds of systems. In recent years, it has come to include many environmental scientists, in particular industrial ecologists. IIOA hosts biannual conferences and more frequent meetings on specific topics to facilitate networking among its members and other interested parties. It also publishes a scholarly journal, "Economic Systems Research", and hosts a website (http://www.iioa.org/) and several modes of electronic communication intended to support and stimulate research activities and data development.
