Introduction

This chapter attempts to evaluate the effects that an eventual North American Free Trade Agreement (NAFTA) between Mexico, Canada, and the United States would have on the Mexican economy, in the presence of economies of scale in the Mexican industry. For that purpose, we show the results of an applied general equilibrium model for Mexico, in which the treatment of economies of scale follows the lines of the Harris (1984) model for Canada. Likewise, it is important to mention that, unlike the results shown in Sobarzo (1992), the present version deals with the removal of both tariff and nontariff barriers (NTBs).

This chapter is organized as follows. Section II presents a brief review on trade policy in Mexico. Section III describes the characteristics of the model. Section IV comments on the main findings. Finally, Section V contains some concluding remarks as well as some comments on the limitations of the approach.

Trade Policy

In 1983, after the debt crisis, the Mexican government conducted extensive trade liberalization that has taken the economy from being one of the most protected in the 1970s to one of the most open by the 1990s. Such measures were implemented in three stages.

In the first stage, from 1983 to 1985, the de la Madrid administration gradually opened the market to foreign participation by simplifying the tariff schedule, reducing the import licensing requirements, and reducing the number of items with official prices.
