Abstract

The objective of this paper is to explain the source of profitability in the Mexican banking system. It also deals with its implications regarding regulatory policy. It test two hypotheses derived from the industrial organization theory: the SCP paradigm and the Efficient Structure Hypothesis. According to the results, we conclude that both help to explain to source of profitability. Therefore, regulatory entities must limit mergers between large banks if efficiency gains are low and market entry does not ensure more competition. If these mergers are allowed, the market entry does not ensure more competition. If these mergers are allowed, the market power created by a more concentrated industry may reduce consumer surplus.// El objetivo de este artículo es explicar el origen de las utilidades de los bancos en México y sus consecuencias en términos de política regulatoria, según dos hipótesis provenientes de la teoría de la organización industrial: el paradigma EDC, que sostiene que una relación positiva entre la concentración industrial y la rentabilidad de los bancos proviene de un mayor poder de mercado, y la hipótesis de eficiencia, que basa su explicación en términos de reducciones en costos. De acuerdo con los resultados econométricos, las hipótesis no son mutuamente excluyentes, por lo que las autoridades reguladoras deben desmotivar las fusiones entre bancos con alta penetración en el mercado si las ganancias en eficiencia son pequeñas y si no están acompañadas de una mayor entrada de instituciones bancarias que generen mayor concentración industrial sólo iría en detrimento de los usuarios de servicios bancarios.
