This experimental study investigates two bargaining games with two-sided incomplete information between a seller and a buyer. In the first game with no outside options many subjects do not use the incomplete information to their advantage as predicted. We find that a model with adjusting priors better explains observed behavior. The second game gives the buyer the option to buy via search or return to bargaining. Here many buyers choose a bargaining agreement when a search outcome is predicted. For those who opt out, search outcomes are overall efficient and behavior is relatively close to the optimal search policy.
