Decomposing growth in a multiregional I-O framework

Since the pioneering work of Wassilly Leontief, a remarkable amount of theoretical and empirical work has continuously supported Input-Output modelling. In particular, the peculiar structure of dynamic input-output (I-O) model have originated, in numerous fields ranging from mathematical economics to system theory, an abundance of contributes. This paper deals with the computational problem of managing regional growth within a dynamic multiregional input-output model. Starting from the basic matrices of technological capital and trade coefficients, the regional components associated to a given group of regions are appropriately recognised and separated. A numerical example, based on the Italian case, is also discussed.An earlier of this paper was presented at the Thirty-fourth Annual Meeting of Western Regional Science Association in San Diego and has benefitted from comments during the conference.
