Abstract

This paper presents a critique on the methodology used in previous research, which attempted to assess the effects on social welfare derived from the existence of firms with market power in Mexico. As a result of the methodological review, the effect generated by a hypothetical collusion between the main competitors in various markets of consumption goods is estimated. The conclusion is that even though there is a significant reduction in the welfare loss estimations in comparison to the other research, this does not demerit the need to strengthen competition policy. On the contrary, by sustaining this policy on a rigorous and objective economic analysis, it is possible to improve its reliability and effectiveness.// En este artículo se presenta una crítica de la metodología utilizada en investigaciones previas que intentaron evaluar los efectos sobre el bienestar social derivados de la existencia de empresas con poder de mercado en México. Como resultado de la revisión metodológica, se estima el efecto provocado por una colusión hipotética de los principales competidores de diversos mercados de bienes de consumo, concluyendo que si bien las estimaciones que se obtienen de la pérdida social son significativamente inferiores a las obtenidas en esas otras investigaciones, no por ello se demerita la necesidad de fortalecer la aplicación de la política de competencia. Por el contrario, al sustentar esta política en un análisis económico más objetivo y riguroso, es posible aumentar su confiabilidad y efectividad.
