Changes in Input-Output Coefficients

  • Per Sevaldson


The question of the tenability of an assumption of stable coefficients has been the subject of innumerable discussions since Leontief first presented his input-output model. I feel that a considerable part of the discussions has been restricted to more or less emphatic statements of belief or disbelief, and even the more temperate discussions have to some extent been characterized by a certain lack of thoroughness, by a lack of systematically investigated evidence, and by a tendency to temporarily shifting positions in the face of apparently unfavourable evidence.
