Deregulation, liberalization and consolidation of the Mexican banking system: Effects on competition
Este articulo analiza la evolucion de la competencia en el sistema bancario Mexicano en el periodo 1993-2005, periodo de desregulacion, liberalizacion y consolidacion del sector. Para ello se utilizan dos medidas de competencia derivadas de la teoria de la Organizacion Industrial: el indice de Lerner y el estadistico H de Panzar y Rosse. La evidencia empirica no permite rechazar la existencia de competencia monopolistica. El indice de Lerner muestra una disminucion en la rivalidad competitiva en el mercado de los depositos y un incremento en el mercado de los prestamos, observandose una estrategia de subsidiacion cruzada entre ambos mercados. Los resultados obtenidos cuestionan la efectivid…
The social costs of bank market power: Evidence from Mexico
This paper estimates the social costs of market power (Harberger's triangle) in the Mexican banking system over the period 1993–2005. It also tests the so-called “quiet life” hypothesis which postulates a negative effect of market power on bank management efficiency. The social cost attributable to market power in 2005 is 0.15% of GDP, while that deriving from the cost (profit) inefficiency of banking management is 0.021% (0.075%) of GDP. The results allow us to reject the quiet life hypothesis in the deposits market. However, market power in the setting of the interest rate on loans has a negative effect on cost efficiency.

The determinants of net interest income in the Mexican banking system: An integrated model
This paper analyzes net interest income in the Mexican banking system over the period 1993-2005. Taking as reference the seminal work by Ho and Saunders (1981) and subsequent extensions by other authors, our study models the net interest margin simultaneously including operating costs and diversification and specialization as determinants of the margin. The results referring to the Mexican case show that its high margins can be explained mainly by average operating costs and by market power. Although non-interest income has increased in recent years, its economic impact is low. El trabajo analiza el margen de intermediación de la banca Mexicana en el periodo 1996-2005.
