Abstract
El Perú es una economía pequeña y abierta al mundo que depende en gran medida de las transacciones con sus socios comerciales y está expuesta a shocks financieros como los creados por la crisis financiera del año 2008. La presente investigación tiene por objetivo contrastar la validez de la Paridad del Poder de Compra entre Perú y EEUU para el período 2000-2018. Para el análisis se emplea la metodología de Johansen para el contraste de relaciones de cointegración y la metodología VAR para la estimación de los parámetros de largo plazo. Los resultados revelan que no se cumple la hipótesis de la Paridad del Poder de Compra para la moneda peruana y el dólar en ninguna de sus formas funcionales planteadas, debido que los parámetros estimados para ambos casos son diferentes de la unidad rechazándose así la hipótesis de eficiencia de mercados en el largo plazo para el Perú y EEUU.
Peru is a small economy and open to the world that depends heavily on transactions with its business partners and is exposed to financial shocks such as those created by the financial crisis of 2008. This research aims to ver-ify the validity of the Purchasing Power Parity between Peru and the US forthe period 2000-2018. Forthe analysis, the Johansen methodology is used forthe contrast of cointegration relationships and the VAR methodology for the modification of long-term parameters. The results reveal that the hypothesis of the Purchasing Power Parity for the Peruvian currency and the dollar is not fulfilled in any of its proposed functional forms, because the parameters estimated for both cases are different from the unit rejected by the hypothesis of long-term market efficiency for Peru and the US.
