Résumé
We study information transmission between an informed expert and an uninformed decision-maker when the decision is binary and the expert does not have a systematic bias. Whenever an equilibrium exists where the decision is delegated to the expert, it is ex ante Pareto-dominant. Adding a round of multilateral communication does not improve information transmission. The decision-maker can, however, improve information transmission by communicating sequentially with two experts. However, introducing multiple rounds of communication (i.e., allowing for rebuttal) does not help.
