Privacy in the Sharing Economy
Despite its increasing relevance, there is a marked lack of research on privacy in the sharing economy literature. Leveraging the theoretical perspective of privacy calculus, we address this gap by investigating how privacy concerns and economic prospects shape a potential providerís intentions to share via different communication channels [...]
Price determinants on Airbnb
Trust is a crucial prerequisite for peer-to-peer rental and sharing. Therefore, platform operators such as Airbnb have implemented a plethora of trustbuilding mechanisms, user interface (UI) artefacts, and reputation systems. While the role of reputation systems for establishing trust is well-understood, little is known about how reputation actually translates into tangible economic value [...]
The Economcis of P2P Online Sharing
Todayís e-commerce landscape has experienced the development of novel markets. While e-commerce was predominantly characterized by business-to-consumer (B2C) structures in the past (Gefen and Straub 2004), today an ever-growing variety of consumer-to-consumer platforms (C2C, often "peer-to-peer," P2P), enables resource [...]
Multi-Hop Ride Sharing
Ride sharing allows to share costs of traveling by car, e.g., for fuel or highway tolls. Furthermore, it reduces congestion and emissions by making better use of vehicle capacities. Ride sharing is hence beneficial for drivers, riders, as well as society. While the concept has existed for decades, [...]

Measuring risk preferences in field experiments
Individual risk preferences can serve as an effective control variable in order to describe human decisions and behavior. Due to limited participants' attention and time, using standard procedures may be difficult. This paper hence proposes a risk preference elicitation task, [...]

Understanding Resource Sharing in C2C Platforms
[...] In this study, we compare different levels of user representations (i.e. picture humanization) in a lab experiment involving 216 users and analyze their effect on usersí sharing behaviour on a C2C platform. Our results indicate that [...]
A note on coupled lotteries
We study the impact of coupling a decision makerís lottery payoffs to those of a peer on the preferred level of risk by means of a lab experiment. Compared to the benchmark where the lotteries are paid off individually, symmetrically coupled payoffs increase the willingness to take risks, whereas asymmetrically coupled payoffs have the opposite effect. [...]
Social Preferences under Risk
This work considers economic decision making, particularly scenarios in which the decision maker faces the presence of other (private) persons. It draws inferences for the design, operation, and use of e-commerce platforms from an economic and information systems perspective and is oriented along two vital concepts therein: social preferences and risk. The role of the type as well as the relation towards the reference person is explored from an empirical and game theoretical perspective.
