The aim of this paper is to examine whether and under what circumstances interactions in the sharing economy lead to an increase in the general perceived trustworthiness of others. In order to study this, we conducted an online field experiment among users of the home sharing platform Airbnb for which we measured participants’ trusting behavior at two points in time. Between these two phases of the experiment, a proportion of our participants had a sharing interaction facilitated by Airbnb: either as a guest, as a host, or as both. We find that sharing has a positive impact on trust, but only when participants have sufficiently many sharing interactions. Furthermore, the positive effect only exists for hosts; we do not find a significant effect for guests.
