We implement multi-sender cheap talk in the laboratory. While full-information transmission is not theoretically feasible in the standard one-sender-one- dimension model, in this setting with more senders and dimensions, full revelation is generically a robust equilibrium outcome. Our...

This paper studies information transmission in a two-sender, multidimensional cheap talk setting where there are exogenous constraints on the (convex) feasible set of policies for the receiver and where the receiver is uncertain about both the directions and the magnitudes of the senders' bias...
