We conduct economic experiments to gauge the level of cooperation between conglomerate rivals. First we run control experiments to observe cooperation between subjects acting as duopolists in one of two markets. In the control experiments, subject pairs choose a quantity xi (or yi) from a payoff...

Cooperative equilibria can be supported in a repeated game when players use trigger strategies. This paper tests how well trigger strategies explain behavior in two-person experimental games. Reducing payoffs for choices larger than the Cournot level induces smaller average outputs, behavior...

Multimarket contact between duopolists in an X and Y market is modelled with a trigger strategy. We show that mildly restrictive price-cap regulation in the X market decreases Y market quantities; but restrictive caps in the X market have a positive impact on Y market outputs. Behavior in...

We analyze data from experimental duopoly markets to assess the role information plays in facilitating collusion. In these markets, profitability can be common knowledge or private information. Market outputs are estimated in structures with symmetric and asymmetric costs under the two...

Using airline-booking data from Sabre, this article documents the proportion of passengers who drive and fly from a hub airport, rather than take a commuter flight. If fewer passengers leaked to a hub, community airports would have more enplanements. Price and quality factors affecting leaks are...
