We study anti-competitive mergers in a dynamic model with noisy collusion. At each instant, firms either privately choose output levels or merge, which trades off benefits of avoiding price wars against the costs of merging. There are three...Read more
This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals’ profits by firms and find that, for demand not too...Read more
