题   目：A Promise Mechanism to Improve Reputation System in Markets: Evidence from An Experimental Study

主讲人：Erte Xiao  professor

摘   要：

An effective reputation system is essential for establishing and maintaining trust in online markets. We design and test a simple promise mechanism aimed at addressing the common challenge of insufficient feedback provision. Before the transaction, a buyer is given the opportunity to make promises regarding leaving feedback. We compare two distinct methods of soliciting promises: Market Promise-solicitation (MP) and Seller Promise-solicitation (SP). In the MP approach, the market automatically prompts buyers to decide whether they will commit to providing feedback to sellers after the transaction, while in the SP approach, sellers themselves request the promise from buyers. We show that theoretically both methods are equally efficient in terms of improving reporting rate and market efficiency. However, our findings from a controlled laboratory experiment demonstrate that SP outperforms MP by generating higher reporting and purchasing rates, resulting in higher market efficiency. The differences between the two align with the expectation-based motivation theory of promise-keeping.
