Contagious Effects of Customer Misbehavior in Access-Based Services

Abstract: Customer misbehavior in service settings is problematic for two reasons: (1) because of the direct damage it causes and (2) because of additional negative effects that arise from the contagion of s...

How the Burdens of Ownership Promote Consumer Usage of Access-based Services

Abstract: Services that let customers access goods, such as car-sharing, are gaining increasing relevance as an alternative to ownership. These access-based services allow consumers to avoid the “burdens of ownership”, i.e., risks and responsibilities that come with owning a good. However, the interplay between consumers’ risk perception of ownership, access-based service usage, and the subsequent decision to reduce or forgo ownership has not been sufficiently investigated. Based on risk perception theory, we hypothesize the effects of different risk dimensions (financial, performance, social) on the intensity of access-based service usage, as well as the latter’s influence on ownership reduction. Using a unique dataset that links survey and actual usage data of car-sharing users, we test four corresponding hypotheses. The results reveal that access-based service usage is positively influenced by all three ownership risk perceptions. Moreover, a higher usage of an access-based service increases the likelihood that consumers subsequently reduce ownership.
