Abstract

Resumen: La integración vertical en el sector salud se refiere a la estructura de gobierno disenada para coordinar y controlar los servicios de atención en diferentes estados de la cadena de valor, así como para facilitar la colaboración y comunicación entre los oferentes de servicios. Para el caso colombiano, la integración vertical supone que los aseguradores (EPS) presten los servicios de salud de forma directa, a través de sus propios centros de atención o redes de servicios (IPS), y es así como se ha dado la creación de IPS por parte de EPS, compras y otras modalidades de integración o control vertical. Se plantea un modelo de doble marginalización (Spengler, 1950), para el caso en el que solo participan una EPS y una IPS y se concluye que cuando hay integración o control vertical de la aseguradora hacia el prestador, los beneficios son mayores que un esquema de firmas independientes; además, el precio final del esquema integrado es menor. / Abstract: The vertical integration in the health sector refers to government’s structure designed to coordinate and control the services of attention in the different states of the value chain, as well as to facilitate the collaboration and communication between the suppliers. In Colombia the vertical integration supposes that the insurers (EPS) lend the health services in a direct way through their own centers of attention (IPS). This situation has motivated the EPS to create their own IPS and other modalities of vertical integration or control. Using a model of double marginalization (Spengler, 1950), that includes only one EPS and one IPS, we conclude that when there is integration or vertical control of the insurance company toward the lender the benefits are bigger than in an scheme of independent firms; also, the final price of the integrated scheme is smaller.
