At a glance The International Input-Output Association (IIOA) is a scientific non-profit membership organisation founded in 1988. Its objective is the advancement of knowledge in the field of input-output analysis, including improve- ments in basic data, theoretical insights and modelling, and applications, both traditional and novel, of input-output techniques. The IIOA grew out of an informal world-wide network of economists, government officials, engineers and managers with interests in input-output analysis.
