Based on data on Mexico and United States of America (U.S.) prices of maize, sorghum and wheat from 1981 to 2010 we show that trade liberalization between Mexico and the U.S. under the North American Free Trade Agreement (NAFTA) resulted in a structural change in prices received by Mexican producers of these crops. We found that this change coincides with convergence with U.S. prices of maize, sorghum and wheat in Mexico food consumption. Hence, the study provides evidence that trade liberalization led to greater integration of Mexico-U.S. agricultural market. We also shown that for the three studied crops, there is a long-term relationship between their price series and an increase in the speed of adjustment of domestic prices in response to changes in international/U.S. prices.]]></p></abstract>

Utilizando datos de precios de México e internacionales para el maíz, sorgo y trigo, de 1981 a 2010, mostramos que el comercio entre México y los Estados Unidos de América (EUA) bajo el Tratado de Libre Comercio de América del Norte (TLCAN) ha implicado cambio estructural en los precios recibidos por los productores mexicanos de estos granos, y que esto ha estado acompañado por la convergencia con sus precios internacionales. Se muestra evidencia que la liberalización condujo a mayor integración de los mercados agrícolas y que hay una relación a largo plazo entre las series de precios, y un aumento en la velocidad de ajuste de los precios internos del maíz, sorgo y trigo en respuesta a cambios en los precios internacionales.]]></p></abstract>
