A century of purchasing power parity confirmed: The role of nonlinearity

  • Kim, Hyeongwoo
  • Moh, Young-Kyu

Taylor (2002) claims that Purchasing Power Parity (PPP) has held over the 20th century based on strong evidence of stationary for century-long real exchange rates for 20 countries. Lopez et al. (2005), however, found much weaker evidence of PPP with alternative lag selection methods. We reevaluate Taylor's claim by implementing a recently developed nonlinear unit root test by Park and Shintani (2005). We find strong evidence of nonlinear mean-reversion in real exchange rates that confirms Taylor's claim. We also find a possible misspecification problem in using the ESTAR model that may not be detected with Taylor-approximation based tests.
