Re‐examining the Evidence for Long‐Run Purchasing Power Parity

Abstract

Corbae and Ouliaris (1991) examined Australia's long‐run real exchange rate and concluded that because the data follow a random walk, purchasing power parity does not hold as a longrun equilibrium relation. We re‐examine their data by calculating non‐parametric measures of persistence and estimating fractionally integrated ARMA models. We find that shocks to the real exchange rate have a finite life. This result is consistent with long‐run purchasing power parity.
