五、内容简介：Reputation systems that rely on feedback from traders are important institutions to help sustain trust in markets, while feedback information is usually considered as a public good. We conduct experiments to study how the raters’ feedback behavior responds to different reporting costs and how to improve the market efficiency by introducing a pre-commitment device for sellers in reputation system. In particular, the pre-commitment device we study here is to allow a seller to provide rebates to cover buyers’ reporting cost before buyer’s purchasing decision. Using a buyer-seller trust game, we find the propensity to leave feedback is more sensitive to reporting cost when the sellers cooperate than when the sellers defect. The seller’s decisions on whether to provide a rebate significantly affect buyers decisions of leaving feedback as the rebates compensate the feedback costs. More importantly, the rebate decision have a significant impact on buyer’s purchasing decision via signaling the seller’s cooperative type.
