We design experimental games to evaluate the predictive power of the first cheap‐talk refinement, neologism‐proofness. In our first set of treatments designed to evaluate the refinement with its usual emphasis on literal meanings, we find that a fully revealing equilibrium that is...

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...

We studied how communication media affect trust game play. Three popular media were considered: traditional face-to-face, Facebook groups, and anonymous online chat. We considered post-communication changes in players' expectations and preferences, and further analyzed the contents of group...
