Total factor producitivity surplus and purchasing power transfers: an application to the Italian economy

In this paper, we disagree on the opportunity to use the double deflation method to produce an equilibrating system of account at a constant price. In fact, by relaxing such a condition, by means of the single deflation method, we obtain a measure of purchasing power transfer that can be decomposed in productivity and market distortion. Results are presented for the evolution of the Italian economy for the periods 1995–2002.
