A Turn of the Tables: Psychological Contracts and Word of Mouth about Sharing Economy Platforms When Consumers Get Reviewed

The Peer-to-Peer sector of the sharing economy relies on reputation systems through which consumers and providers review each other. Whereas prior research has examined the effects of reviews by consumers on providers and firms, this research examines, for the first time, a turn of the tables in which consumers are evaluated. Across a pilot and seven studies (five preregistered), using multiple actual behaviors and sharing contexts, results reveal that a negative review of the consumer from the peer provider leads to negative word of mouth (NWOM) about the platform. Drawing from psychological contract theory, the research demonstrates that this effect is mediated by consumers' perceived betrayal by the platform. Two sets of moderators are identified. The first set establishes that a breach of consumers' psychological contract with the platform underlies the effect. In the second set, platform policies that may render a breach more or less consequential can intensify or mitigate consumer reactions. Specifically, making the review private (vs. public) and providing opportunities for justice restoration (response, revenge, and dispute) attenuate the effect of review valence on betrayal and NWOM. Implications for sharing economy platform managers and consumers are discussed.
