The Concept of Accuracy in Regional Input-Output Models

This paper focuses attention on the concept of accuracy in regional input-output tables. Two interpretations of accuracy, namely partitive and holistic accuracy, are discussed with reference to interpretation of input-output tables. Implications are drawn from recent contributions to the regional input-output literature in terms of the `reconciliation' debate and the survey versus non-survey debate. Holistic accuracy is the only concept which is tenable in practice; some suggested criteria for holistic accuracy are provided.
