Integración Vertical Eficiente y Compartimiento de Facilidades en Presencia de Entrada: Un Marco Conceptual

Author

Abstract

En este artículo se estudian los equilibrios de mercado resultantes en una industria de facilidades esenciales, con un monopolio upstream y competencia oligopólica downstream, la que enfrenta posteriormente entrada en el segmento monopólico. Se encuentra que la competencia de duopolios verticalmente integrados es el resultado de equilibrio postentrada, con competencia de facilidades esenciales cuando los costos de construcción de una nueva facilidad son bajos y con compartimiento de la facilidad esencial upstream cuando sus costos de construcción son elevados. Asimismo, los efectos en bienestar social son siempre eÞcientes cuando se observa duplicación de facilidades; siendo en varios casos eÞcientes cuando se observa en equilibrio compartimiento de facilidades. Estos resultados proveen racionalidad para la mantener desregulada industrias como la petrolera, en donde los costos hundidos son más bien bajos relativos al tamaño del mercado.
