An Experimental Study on the Effects of Communication, Credibility, and Clustering in Network Games

Gary Charness, Francesco Feri, Miguel A. Meléndez-Jiménez, and Matthias Sutter

Abstract
We examine how pre-play communication and clustering affect play in a challenging hybrid experimental game on networks. Free-form chat is enormously effective in achieving the non-equilibrium efficient outcome, but restricted communication is almost entirely ineffective. We support this result with a model about the credibility of cheap-talk messages. We provide a model of message diffusion, which correctly predicts that diffusion will be more rapid without clustering. We also show an interaction effect of network structure and communication technologies. A remarkable result is that restricted communication is quite effective in a network Stag Hunt, but not in our extended game.
