Although the need for aggregation in input-output modeling has diminished with the increases in computing power, an alarming number of regional studies continue to use the procedure. The rationales for doing so typically are grounded in data problems at the regional level. As a result many regional analysts use aggregated national input-output models and trade-adjust them at this aggregated level. In this paper,we point out why this approach can be inappropriate. We do so by noting that it… CONTINUE READING
