Abstract How does quality-certi cation a ect product quality in markets? We exploit a policy change on eBay to analyze how a more stringent certi cation policy a ects entry and behavior across many markets segments. We nd that rst, entry increased in markets where it was harder to get certi ed, until a new steady state was reached. Second, the quality distribution of entrants exhibits fatter tails after the policy, and overall quality is slightly higher. Last, some incumbents respond by increasing the quality of their service to maintain certi cation. The results inform the design of certi cation policies in electronic and other markets.
