Abstract: This paper presents evidence on the impact of bank-specific, regulatory, institutional, macro and financial development variables on competition in banking, using information at both national and bank level. With this aim, Lerner indices of market power are estimated using a sample of 10,479 annual observations over the period 1995-99 across 58 countries. Results show that although bank-specific characteristics explain a substantial proportion of market power, market structure variables and, above all, the level of financial development also help to explain the differences observed in the levels of banking competition. Regulatory impediments to competition are not significant when controlling for financial development. Este artículo presenta evidencia del impacto que las variables específicas de cada banco, las regulatorias, institucionales, macroeconómicas y de desarrollo financiero ejercen sobre la competencia bancaria, utilizando información tanto a escala nacional como a nivel de empresa. Con este objetivo, se estiman índices de Lerner de poder de mercado utilizando 10.479 observaciones durante el periodo de 1995-99 para una muestra de 58 países. Los resultados muestran que, aunque las características específicas de cada banco explican una parte sustancial del poder de mercado (especialmente el tamaño y la eficiencia), las variables de estructura del mercado, y, sobretodo, el nivel de desarrollo financiero también ayudan a explicar las diferencias observadas en los niveles de competencia bancaria. Las barreras regulatorias a la competencia no son significativas cuando se controla por desarrollo financiero.
