You never know what you will get in an Airbnb: poor communication destroys value for guests

ABSTRACT

This study explores the antecedents of value co-destruction in the context of a new form of accommodation, Airbnb. Data were gathered using semi-structured interviews from people who had stayed in Airbnb accommodations during the previous 12 months. A total of 21 interviews were conducted, of people representing five nationalities. Using the grounded theory approach, the findings indicate that poor communication between the guest and host was one of the main reasons contributing to value co-destruction during the Airbnb accommodation experience. From the guest perspective, value co-destruction due to poor communication resulted in unexpected resource losses, including time and money. One interviewee also regretted the lost experience. Although the majority of the interviewees did not have negative Airbnb accommodation experiences, some did not experience a reciprocal and mutually beneficial relationship.

Home alone and often unprepared – intercultural communication training for expatriated partners in German MNCs

This article reports the results of a study of partners who accompany the expatriated representatives of multinational corporations (MNCs) on overseas missions and identifies that they are mostly home alone and often unprepared. Following a review of the literature on issues related to expatriated partners, in particular intercultural communication training (ICT), the article presents the findings of empirical research conducted in Germany on current ICT trends for expatriated partners. The study identifies the ICT methods German MNCs use to support these partners before and during international assignments. The authors surveyed 141 German expatriated partners who went on overseas missions to 36 countries. The results of this research project indicate that traditional ICT is only provided to the minority of partners in German MNCs, follows no predictable time pattern, and is mostly perceived as rather useless by participants. Particular attention is paid, however, to the target culture in the ICT design. Non-traditional ICT methods, such as Look-&-See Trips, are rather generously taken advantage of.
