CAMACHO GARCIA, Ma. Ofelia  e  FLAMAND, Laura. Intergovernmental Policies for Controlling Air Pollution in Mexican Cities: an Evaluation. Gest. polít. pública [online]. 2008, vol.17, n.2, pp.261-313. ISSN 1405-1079.

The increasingly evident deterioration of public health due to atmospheric pollution has forced governments to design and implement diverse policies for the control of air pollutants. Relying on quantitative methods, we investigate the effectiveness of intergovernmental policies for the abatement of air pollution in four metropolitan areas (Guadalajara, Monterrey, Valle de Mexico, and Valle de Toluca) over a ten year period. Our statistical analysis shows that, when observed concurrently, the efforts of these governments to reduce the concentrations of sulphur and nitrogen dioxids have been effective only partially. In the cases of Guadalajara and Monterrey, our qualitative analysis reveals that specific characteris-tics of these policies (the degree of participation of industries and municipal governments) and the existence of international commercial liaisons (export-oriented industries tend to adopt environmental-friendly policies) explain, to a large extent, the evolution of the concentration of pollutants in each city.
