Abstract
The nineteenth-century economic commentators did not possess a formal measure of the rate at which productivity was increasing during the industrial take-off. Yet they did develop an intuitive method based on the comparative change in long-period prices and wages. This paper reviews the contributions of G.R. Porter and R. Giffen and, in the light of some modern contributions, presents an assessment of their rationality and improvability under current standards. It is argued that a proper measure of industrial productivity increase based on long-run prices is the mathematical dual of a Solovian measure of the industrial total factor productivity growth.Pubblicazioni consigliate
