WALLACE, Frederick H.; LOZANO CORTES, René  e  CABRERA CASTELLANOS, Luis Fernando. Pruebas de cointegración de paridad de poder de compra. EconoQuantum [online]. 2008, vol.4, n.2, pp.7-25. ISSN 2007-9869.

Three well-known single equation cointegration tests are employed to test for purchasing power parity (PPP) in updated version of the data set developed by Taylor (2002). Results of the tests differ somewhat. The Engle-Granger two-step procedure indicates substantial support for PPP with respect to the US dollar while the evidence in favor is much weaker from error correction and autoregressive distributed lag models.
