We show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g. an equipment manufacturer) to provide it with a discrete input, and if the supplier has market power, investment...

Regulation (EC) No 1217/2010 on the application of Article 101(3) of the Treaty on the Functioning of the European Union to categories of R&D agreements exempts horizontal R&D agreements from antitrust concerns when the combined market share of participants is low enough. We examine the...

This note extends the characterization of simultaneous investment (tacit collusion) equilibria in Boyer, Lasserre and Moreaux (2012). Tacit collusion equilibria may or may not exist, and when they do may involve either finite time investments (type 1) or infinite delay (type 2). The relationship...

Collusion sustainability depends on firms' aptitude to impose sufficiently severe punishments in case of deviation from the collusive rule. We characterize the ability of oligopolistic firms to implement a collusive strategy when their ability to punish deviations over one or several periods...

This note establishes that two propositions in the theory of private common agency by Laussel and Le Breton (2001, J. Econ. Theory 100, 93-128) extend to a larger class of games, in which each principal’s gross monetary payoff does not depend exclusively on the quantities she receives. A new...

Collusion sustainability depends on firms' aptitude to impose sufficiently severe punishments in case of deviation from the collusive rule. We extend results from the literature on optimal collusion by investigating the role of limited liability. We examine all situations in which either...
