Mots clés : Certification, Reputation, Multihoming


In a market where sellers solicit certification to overcome asymmetric information, we show that the profit of a monopolistic certifier can be hump-shaped in its reputation for accuracy: a higher accuracy attracts high-quality sellers but sometimes repels low-quality sellers. As a consequence, reputational concerns may induce the certifier to reduce information quality, thus depressing welfare. The entry of a second certifier impacts reputational incentives: when sellers only solicit one certifier, competition plays a disciplining role and the region where reputation is bad shrinks. Conversely, this region may expand when sellers hold multiple certifications
