Abstract
From half-full of the 60 is appraised an important study of the phenomenon of the inflation in the industrialized economies, process that later extends to numerous countries developing. This process takes place in an intellectual context where the influence of ideas like “the hypothesis of the natural rate” is appraised, the importance of the “rational expectations” and the “neutrality of long term” of the monetary policy.
