Abstract

Esta investigación busca analizar si el mercado de aseguramiento en salud en Colombia está concentrado, y si esa concentración influye en el acceso a servicios de salud. Para esto se estiman modelos de forma reducida, utilizando información de prestación de servicios de salud para 33 áreas de mercado en el periodo 2007-2011. Como principal resultado se verifica la existencia de mercados concentrados, y se encuentran evidencias de que estas aseguradoras ejercen también influencia sobre la producción de servicios hospitalarios. Todo ello conlleva a que el ejercicio del poder de mercado de las aseguradoras se convierte en potenciales limitantes del acceso a los servicios médicos.
