Long memory and structural breaks in hyperinflation countries

  • Guglielmo Maria Caporale
  • Luis A. Gil-Alana


In this paper we examine the stochastic behavior of prices in hyperinflation countries by using a fractional integration test (Robinson 1994) that lends itself to incorporating structural breaks into the model. We focus on Argentina, Brazil, and Israel and find that when allowing for structural breaks, in the form of slope dummies (or squared slope dummies), the order of integration of the series decreases considerably. Especially in the case of Brazil, the degree of persistence of inflation seems to be less substantial than estimated in other studies, which might be interpreted as evidence against “heterodox” inflation stabilization.
