Abstract:
Decision makers often face uncertainty about the ability and the integrity of their
advisors. If an expert is sufficiently concerned about establishing a reputation for being
skilled and unbiased, she may truthfully report her private information about the
decision-relevant state. However, while in a truthtelling equilibrium the decision maker
learns only about the ability of the expert, in an equilibrium with some misreporting
she also learns about the expert’s bias. Although truthtelling allows for better current
decisions, it may lead to worse sorting outcomes. Therefore, if a decision maker is
sufficiently concerned about future choices, lying may be welfare improving.
