Do Mergers Result in Collusion ?
We examine coordinated effects of mergers in the Swedish retail market for gasoline during the period 1986-2002. Despite significant changes in market concentration and many factors conducive to coordination, the empirical analysis shows that the level of coordination is low. In addition, statistical tests reject the hypothesis that mergers and acquisitions result in ”coordinated effects”. In p...
متن کاملDo Vertical Mergers Facilitate Upstream Collusion?∗
In this paper we investigate the impact of vertical mergers on upstream firms’ ability to sustain collusion. We show in a number of models that the net effect of vertical integration is to facilitate collusion. Several effects arise. When upstream offers are secret, vertical mergers faciliate collusion through the operation of a foreclosure effect: Cheating unintegrated firms can no longer prof...
متن کاملMergers and collusion in all-pay auctions and crowdsourcing contests
We study the effects of bidder collaboration in all-pay auctions. We analyse both mergers, where the remaining players are aware of the agreement between the cooperating participants, and collusion, where the remaining players are unaware of this agreement. We examine two scenarios: the sum-profit model where the auctioneer obtains the sum of all submitted bids, and the max-profit model of crow...
متن کاملDo hospital mergers reduce costs?
Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically ...
متن کاملHow Do Disks Survive Mergers?
We develop a general physical model for how galactic disks survive and/or are destroyed in mergers and interactions. Based on simple dynamical arguments, we show that gas primarily loses angular momentum to internal torques in a merger, induced by the gravity of the secondary. Gas within some characteristic radius, determined by the efficiency of this angular momentum loss (itself a function of...
