We compare a Bertrand with a Cournot duopoly in a setting where production is polluting and exploits natural resources …, and firms bear convex production costs. We adopt Dastidar's (1995) approach, yielding a continuum of Bertrand …

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the … downstream level. In contrast to the case of constant marginal costs, vertical integration does not imply complete market …

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition … is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can … paid by the non-merging firms the merger thereby shifts production away from those relatively inefficient producers in …
