Abstract

In recent years, a growing interest among authorities has emerged to verify which paradigm better explains the profit-structure relationship in the Mexican banking industry: market power or efficiency. To test these two paradigms, this work constructs specific indicators of cost efficiency based on the efficiency frontier concept. This is done in order to incorporate these indicators into the traditional profit-structure test. In contrast to previous studies, this study finds empirical evidence in favor of the market power hypothesis only.// En años recientes ha surgido un creciente interés por verificar el paradigma que mejor explica la relación entre la estructura de mercado y las ganancias en el sistema bancario mexicano: poder de mercado o eficiencia. Para poner a prueba estos paradigmas, en este artículo se elaboran indicadores específicos de eficiencia basados en el concepto de frontera eficiente, los cuales se incorporan en la prueba tradicional de estructura de mercado-conducta-desempeño. En contraste con estudios anteriores, en este artículo se encuentran pruebas en favor sólo de la hipótesis de poder de mercado.
