Tomando en consideración la sensibilidad de cada industria a la rapidez con la que se eliminan los aranceles bajo el TLCAN, los resultados muestran que los MPCM cayeron inmediatamente después de que comenzó en México la segunda ronda de liberalización comercial en 1994. Sin embargo, en años subsecuentes, no emerge un patrón claro para estos MPCM. Adicionalmente, el estudio toma en cuenta la sensibilidad de cada industria al nivel inicial de su arancel y presenta evidencia que muestra que mientras que el TLCAN sí tuvo un efecto sobre los MPCM de aquellas industrias que liberalizaron en 10 años, no se encontró un efecto robusto sobre los MPCM de las industrias que liberalizaron en cinco años.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This paper analyzes the effect of the North American Free Trade Agreement (NAFTA) on Mexican manufacturing price cost margins (PCMs) for the period 1994-2003. Taking into account the sensitivity of each industry to the speed of the tariff reductions under NAFTA, the results show that PCMs immediately decreased once the second round of trade liberalization in Mexico had commenced in 1994. However, in subsequent years, no clear pattern emerges for these PCMs. Additionally, the paper accounts for the sensitivity of each industry to the initial level of its tariff and presents evidence showing that while NAFTA had an effect on the PCMs of the group of industries that liberalized in 10 years, no robust effect was found for the group of industries that liberalized in five years.]]></p></abstract>
