-talk communication raises efficiency in bilateral contracting situations with adverse selection. We replicate their finding and check its … robustness by introducing competition between agents. We find that communication and competition act as "substitutes …:" communication raises efficiency in the absence of competition but lowers efficiency with competition, and competition raises …

Costless pre-play communication has been shown to effectively facilitate within-group coordination. However, in … costly efforts. We find that allowing within-group communication makes groups compete more aggressively. When only one group …. However, the communicating group earns payoffs that are not different from the baseline contest without any communication …

equally in groups of optimal size and there is no communication. The assignment of individuals to groups as either strangers … or partners does not significantly affect this outcome. In this paper we investigate whether communication changes these … results. Communication reduces shirking, increases aggregate effort and reduces aggregate rents, but only when communication …
