Nonlinearities And Price Puzzle In Brazil


  • Roberto Tatiwa Ferreira
  • Ivan Castelar


What is called a price puzzle is a positive and persistent response of ination to a unit shock in the interest rate's innovation. Using a VAR to analyse monetary policy in Brazil, this paper comes to the conclusion that when nonlinearities in the data were considered, most of this e_ect vanishes. This is done _rstly by checking if the series are unit root processes or nonlinear trend stationary. After that a nonparametric co-trending analysis was applied. The test result favored a common nonlinear trend between ination and the interest rate, which seems to a_ect the system innovation analysis, inducing most of the price puzzle e_ect.
