This paper presents new arguments for some recent stylized facts about the dynamics of inflation shown by Mishkin (2007), which are: a) the persistence of inflation shocks are declining; b) the Phillips' curve of this becoming more horizontal and; c) inflation has been less reactive to shocks on prices. It addressed the problem of determining the aggregate supply where the new version of the Keynesian Phillips' curve, that despite progress, not yet incorporating the determinants of the expansion potential of the product and that this inclusion is one of the explanations for stylized facts (fact b ) revealed recently by Mishkin.
