In general, a reduction in trade barriers will affect the environment by expanding the scale of economic activity, by altering the composition of economic activity and by initiating a change in the techniques of production. We present empirical evidence to assess the relative magnitudes of these three effects as they apply to further trade liberalization in Mexico. We first use comparable measures of three air pollutants in a cross-section of urban areas located in 42 countries to study the relationship between air quality and economic growth. We find for two pollutants (sulphur dioxide and 'smoke') that concentrations increase with per capita GDP at low levels of national income, but decrease with GDP growth at higher levels of income. We then study the determinants of the industry pattern of US imports from Mexico and of value added by Mexico's maquiladora sector. We investigate whether the size of pollution abatement costs in US industry influences the pattern of international trade and investment. Finally, we use the results from a computable general equilibrium model to study the likely compositional effect of a North American Free Trade Agreement (NAFTA) on pollution in Mexico.

Examines (1) the overall economic effects of the NAFTA on the economies of the U.S., Mexico, and Canada; (2) the key NAFTA provisions and related legal changes that may affect individual sectors; and (3) the short- and long-term impact of NAFTA on important industrial, energy, agricultural, and service sectors of the U.S. economy. Also summarizes recent economic developments in Mexico. Tables and figures.
