Certification is a ubiquitous tool that alleviates information asymmetries in markets, yet little is known about the impact of certification selectivity on market outcomes. Exploiting a policy change on eBay, we study how a more selective certification threshold affects entry, exit, and incumbent behavior. We develop a stylized model which shows that changes in selectivity impact the distribution of quality and prices in predictable ways. Using rich data from hundreds of online categories on eBay.com, we find support for the model’s hypotheses.  Our results help inform the design of certification selectivity in electronic and other markets.
