Abstract

In 2008, Mexico’s Federal Competition Commission (CFC) commissioned a study of the distributive effects of market power which has influenced the national discussion on competition policy. In this paper, we attempt to replicate its results, we extend them to future years, identify and correct deficiencies in the analysis, and evaluate the conceptual and methodological framework employed. We conclude that the method used does not produce reliable results. Furthermore, using the same method, we estimate a welfare loss between 0.8 and 2.1% of total spending, depending on the income decile. While the conclusion that lower income households are more severely affected by the exercise of market power holds, we find that this effect is greater in urban areas than in rural areas for the lowest income households.// En 2008, la Comisión Federal de Competencia (CFC) comisionó un estudio de los efectos distributivos del poder de mercado que ha influenciado la discusión nacional respecto a la política de competencia. En este artículo, intentamos reproducir sus resultados, los extendemos a años posteriores, identificamos y corregimos deficiencias en su análisis, y evaluamos su marco conceptual y metodológico. Documentamos que el método utilizado no produce resultados confiables. Además, usando el mismo método, estimamos una pérdida en bienestar de entre 0.8 y 2.1% del gasto total, dependiendo del decil de ingreso. Aunque se sostiene la conclusión de que los hogares de menores ingresos se ven más afectados por el ejercicio de poder de mercado, encontramos que, para los hogares de ingresos más bajos, este efecto es mayor en zonas urbanas que en zonas rurales
