Nonsurvey Techniques: A Critical Review of the Theory and the Evidence

Nonsurvey methods, including methods of constructing regional input-output tables, reconciling estimates, and deriving sectoral multipliers where no input-output table exists, are critically evaluated from a theoretical point of view as well as in the light of available evidence. There are a number of weaknesses in the way many techniques are utilized, and there are decided advantages in pursuing an interregional or multiregional approach. The continuing claims about the accuracy of existing methods are also examined in the context of the efficacy of various test procedures.
