This study aims to investigate the influence of a male and female sellers ́ profile image and its expressions on the choices made by the peer user within the context of peer-to-peer accommodation rental. We arranged a scenario in which participants evaluated their likelihood to rent an apartment on Airbnb. Results of the conjoint study (r = 0.967, p = 0.000) show that, relative to price and customer reviews, a seller ́s profile image and its facial expression has a strong impact on the likelihood to rent the apartment on Airbnb. Second, the male seller profile image and its facial expression had the strongest impact in both positive and negative directions. Finally, the absence of a seller’s profile image (head silhouette) had a relatively strong negative impact on the likelihood to rent. Sellers looking to sublet property on Airbnb should be aware that their profile image could potentially influence prospective tenants. The study is published in Procedia Computer Science.
