In many industries, output is fixed by exogenous constraints, so firms compete by allocating a given stock of supplies between different markets. This paper shows that collusion in such industries leads firms to shift output from high-margin markets to low-margin markets. As a result, welfare is...

This paper introduces a number of game-theoretic tools to model collusive agreements among firms in vertically differentiated markets. I firstly review some classical literature on collusion between two firms producing goods of exogenous different qualities. I then extend the analysis to a...

Partial cross ownership (PCO) among firms affects their incentives to engage in tacit collusion. We analyze collusion behavior in an n-firm industry which allows asymmetric cross ownership, under Cournot competition. We find that in some ways increasing PCO hinders tacit collusion under the...

Recent years have witnessed an increased interest, by competition agencies, in assessing the competitive effects of partial acquisitions. We propose an empirical structural methodology, which can deal with settings involving all types of owners and ownership rights, to quantify the coordinated...

We experimentally investigate the determinants of post-cartel tacit collusion (PCTC), the effects of PCTC on market outcomes, and potential policy measures aimed at its prevention. PCTC occurs robustly with or without fines or leniency and is determined both by collusive price hysteresis and...

We suggest a price signaling strategy that offers a microfoundation for the process leading to tacit collusion under multimarket contact, even in cases where previous theoretical explanations fail. It rests on the assumptions that firms can communicate collusive intentions solely through their...

We experimentally study the effect of information about competitors' actions on cartel stability and firms' incentives to form cartels in Cournot markets. As in previous experiments, markets become very competitive when individualized information is available and participants cannot communicate....

We study the collusive efficacy of competition clauses (CC) such as the meeting competition clause (MCC) and the beating competition clauses (BCC) in a general framework. In contrast to previous theoretical studies, we allow for repeated interaction among the retailers and heterogeneity in their...

This paper analyzes the role of communication between firms in an infinitely repeated Bertrand game in which firms receive an imperfect private signal of a common value i.i.d. demand shock. It is shown that firms can use stochastic, inter-temporal market sharing as a perfect substitute for...

The objective of this paper is to investigate the impact of R&D cooperation on cartel formation in the product market. The R&D investments that precede the production process are aimed at the reduction of the unit manufacturing costs, and could create positive externalities for the potential...
