We theoretically and empirically examine used car dealers' roles as information intermediaries when asymmetric information is present. Our parsimonious theoretical model predicts that a dealer's price premium (over private sellers) in dollar terms is hump-shaped in car age, and in percentage terms is increasing in car age. The model also predicts that dealer cars are less likely to be resold after a transaction, due to their higher unobserved quality compared to cars sold by private sellers. Our theoretical findings are consistent with administrative data on used car transactions from two large U.S. states.
