Extended Time Horizons

Input–output analysts are often confronted with requests for impacts assessments for economic shocks that stretch uncomfortably the assumptions of standard input–output modeling. This paper presents an approach to confronting a subset of these challenges straightforwardly in a way that ameliorates some of the more restrictive input– output assumptions, maintains the inter–industry detail of the input– output model, and enhances the representation of certain economic behaviors without the additional complexities of moving to more complex computable general equilibrium or conjoined econometric input– output models. We conclude with the observation that direct changes to the input–output framework most often necessitate further modifications requiring additional behavioral assumptions and decisions on the part of the modeler.
