摘要：I analyze the impact of seller reputation on prices using data from
Amazon.com. The book, The Da Vinci Code was selected to investigate this
impact because it is one of the best-selling books of all time and has a welldeveloped
market for used copies. The results suggest that sellers with better
reputations are more efficient than others and that the costs of developing
these reputations are not passed on to consumers. In addition, the consumer
benefits from lower prices. This result contrasts with those found by Melnik
and Alm (2002) and Dewan and Hsu (2004). JEL: D820, L810.
