Professional Advice: The Theory of Reputational Cheap Talk
AbstractProfessional experts offer advice with the objective of appearing well informed. Their ability is evaluated on the basis of the advice given and of the realized state of the world. This situation is modeled as a reputational cheap-talk game in which the expert receives a signal of continuously varying intensity with ability-dependent precision about a continuum of states. Despite allowing an arbitrarily rich message space, at most two messages are sent in equilibrium. The expert can only credibly transmit the direction but not the intensity of the information possessed. Equilibrium advice is then systematically less informative than under truthtelling.
