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...

We consider a seller s ability to deter potential entrants by offering exclusive contracts to its downstream buyers. Rasmusen, Ramseyer, and Wiley (1991) showed that this can be a pro fitable strategy if there is a coordination failure on the part of the buyers. Segal and Whinston (2000) showed...

We analyse the key determinants of umbrella effects, which arise when the price increase or quantity reduction of a cartel diverts demand to substitute products. Umbrella effects arise irrespective of whether non cartelists act as price takers (“competitive fringe”) or respond strategically...

Using the coefficient of cooperation, we analyse the effect of cost asymmetries on collusive agreements when firms are able to coordinate on distinct output levels than the unrestricted joint profit maximization outcome. In this context, we first investigate the extent to which collusive...

In this paper, a dominant supplier and competitive fringe supply goods to a common buyer who has private information about the state of demand. We give conditions under which market-share contracts are profitable, and we show that, in some cases, the full-information outcome can be obtained...

We analyze firms' ability to sustain collusion in a setting in which horizontally differentiated firms can price-discriminate based on private information regarding consumers' preferences. In particular, firms receive private signals which can be noisy (e.g., big data predictions). We find that...

Traditionally, the way competition law has viewed the exchange or sharing of information among competing firms, has been to some extent mainly negative, at least from the supply side. Present market conditions, an excessively transparent market, where operators exchange detailed and (prospect)...

We analyze collusion in an infinitely repeated Bertrand game, where prices are publicly observed and each firm receives a privately observed, i.i.d. cost shock in each period. Productive efficiency is possible only if high-cost firms relinquish market share. In the most profitable collusive...
