How does the politician's reputation concern affect information provision when the information is endogenously provided by a biased lobbyist? I develop a model to study this problem and show that the answer depends on the transparency design. When the lobbyist's preference is publicly known, the politician's reputation concern induces the lobbyist to provide more information. When the lobbyist's preference is unknown, the politician's reputation concern may induce the lobbyist to provide less information. One implication of the result is that given transparent preferences, the transparency of decision consequences can impede information provision by moderating the politician's reputational incentive.
