摘要：In markets, sellers tend to oversell, by exaggerating the quality of their goods. We study an information design problem between a seller and a buyer with two-sided asymmetric information. The buyer knows her valuation for the good and the seller can assess its quality. We show that the model rationalizes overselling, even when the buyer is a rational Bayesian. Moreover, overselling is robust to whether the buyer can haggle. Compared to full disclosure, overselling is Pareto improving, making both the seller and the buyer strictly better off. A policy implication is that a benevolent central planner should not enforce full disclosure.
