In this paper we study the behavior of rivals when there is a known probability of imminent entry. Experimental markets are used to collect data on pre‐ and postentry production when there is an announced time of possible entry; some markets experience entry and other do not. In all preentry markets competition is more intense. Postentry behavior in all markets is more competitive compared to a baseline that had no threat. There is evidence that postentry multimarket contact raises outputs in those markets that did not experience entry, behavior we generally refer to as a conduit effect.
