Since, in the NAFTA era, the Mexican economy is much more advanced in the manufacturing sector than those of other Latin American countries, Mexico competes directly with China for U.S. imports. This study empirically investigates the behavior of the Mexican peso/Chinese yuan, Mexican peso/U.S. dollar, and Chinese yuan/U.S. dollar real exchange rates to determine whether the exchange rate policies serve as contributing factors to the subpar performance of the Mexican economy. The empirical findings suggest that the Mexican, Chinese, and U.S. real exchange rates, over the sample period, prove consistent with predations of the purchasing power parity theory; therefore, exchange rate policies may not be a contributing factor to the poor performance of the Mexican economy.
