Abstract
AbstractWe present a multidimensional generalization of the GRAS method (nD‐GRAS) for the estimation of multiple matrices in an integrated framework. The potential applications of this method in regional and multi‐regional input–output analyses based on national/regional accounts frameworks are many. We provide two real applications, a 3D‐GRAS that estimates a use table at basic prices jointly with valuation matrices for Denmark; and a 4D‐GRAS for estimating intercountry input–output tables with OECD data. We show that higher dimensional GRAS methods provide more consistent and accurate estimates than those with lower number of dimensions. We provide the analytical closed‐form solution and the RAS‐like algorithm for an easy operationalization.
