Abstract

In this paper, we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under the assumption and those resulting from the traditional example considered in the literature, namely, a constant returns technology.
