Abstract

En este artículo se discuten los efectos de escalar los cargos de acceso por sobre los costos marginales en los incentivos de un operador de telefonía local integrado verticalmente a implementar una práctica de precios predatorios en algunos de los servicios desregulados (e.g., larga distancia, internet). Utilizando un modelo de Hotelling de competencia en precios entre dos empresas, encontramos que los incentivos a la predación caen con el escalamiento. Aunque el escalamiento hace menos costosa la predación, éste a su vez, hace menos atractiva la predación, ya que las utilidades de las empresas en el equilibrio duopólico son mayores. Este último efecto siempre domina al efecto de menor costo.
