The conventional input-output model has been widely criticized, both justly and unjustly, for its limiting assumptions. One of these assumptions is homogeneity of degree one. This paper explores some approaches to minimize this limitation of traditional input-output analysis by removing the...

This article presents an overview of the hybrid approach to the construction of regional input-output tables. As an example, the Australian GRIT system is described in some detail. Some of the shortcomings and weaknesses of the current models are discussed, together with suggestions for future...

This paper examines the nature of uncertainty in integrated econometric+input-output (ECIO) regional models. We focus on three sources of uncertainty: [a] econometric model parameter uncertainty; [b] econometric disturbance term uncertainty; and [c] input-output coefficient uncertainty. Through...
