En mercados eficientes, los precios corrientes reflejan toda la información disponible. Los precios pasados no contienen ninguna información útil para predecir precios futuros y realizar ganancias extraordinarias. Este principio, hipótesis débil de la eficiencia informativa de los mercados, ha sido incorporado a la teoría de la paridad del poder adquisitivo (PPA), a fin de sobreponer sus limitaciones en el análisis intertemporal del ajuste de los tipos de cambio a las tendencias inflacionarias. En general, estudios de mercados de divisas de los países desarrollados validan su eficiencia; sin embargo, la investigación para el caso de los países en vías de desarrollo es limitada. En este trabajo se analiza la eficiencia de los mercados de divisas de 15 países latinoamericanos para el periodo 1970-2000. Basándose en el modelo ampliado de PPA, se aplican dos modelos de análisis de regresión y uno de raíz unitaria.

This paper presents some empirical evidence on long-run purchasing power parity (PPP) for eight Pak-rupee exchange rates over the period 1982:1–1994:4. Results obtained from testing for cointegration and coefficient restrictions using the Johansen (1988, 1991) procedure are supportive of PPP in almost all cases. These results are also supported by those obtained from testing for mean reversion in the real exchange rate using the Sims (1988) Bayesian test. One of the conclusions that emerge from these results is that devaluation of Pak-rupee vis-à-vis major industrial currencies under investigation may be unlikely to improve the country’s external competitiveness and, consequently, the deficit in its trade balance.
