We study a bargaining model in which a buyer makes frequent offers to a privately informed seller. In addition, the buyer gradually learns about the seller’s type from “news.” We show that the buyer’s ability to leverage this information to extract more surplus from the seller is remarkably limited. In fact, the buyer gains nothing from the ability to negotiate a better price despite the fact that a negotiation takes place in equilibrium. During the negotiation, the buyer engages in a form of costly “experimentation” by making offers that are sure to earn her negative payoffs if accepted, but improve her information and continuation payoff if rejected. We investigate the effects of market power by comparing our results to a setting with competitive buyers. Surprisingly, both efficiency and the seller’s payoff can decrease by introducing competition among buyers.
