Abstract

In this paper we extend the collusion framework to allow for heterogeneity among firms, investment, entry and exit. The focus is on a model with symmetric information in which it is hard to sustain collusion when either; one of the firms does not keep up with the advances of its competitors (both inside and outside the industry), or a "low quality" entrant enters.
