PublicationBlissfully Ignorant: The Effects of General Privacy Concerns, General Institutional Trust, and Affect in the Privacy CalculusExisting research on information privacy has mostly relied on the privacy calculus model, which views privacy-related decision-making as a rational process where individuals weigh the anticipated risks of disclosing personal data against the potential benefits. In this research, we develop an extension to the privacy calculus model, arguing that the situation-specific assessment of risks and benefits is bounded by (1) pre-existing attitudes or dispositions, such as general privacy concerns or general institutional trust, and (2) limited cognitive resources and heuristic thinking. An experimental study, employing two samples from the USA and Switzerland, examined consumer responses to a new smartphone application that collects driving behavior data and provided converging support for these predictions. Specifically, the results revealed that a situation-specific assessment of risks and benefits fully mediates the effect of dispositional factors on information disclosure. In addition, the results showed that privacy assessment is influenced by momentary affective states, indicating that consumers underestimate the risks of information disclosure when confronted with a user interface that elicits positive affect.

PublicationQuantitative Longitudinal Research: A Review of IS Literature, and a Set of Methodological GuidelinesData captured at different points in time provides the basis for longitudinal research. It is unquestioned that several IS phenomena deal with change over time such as post-adoption behavior with respect to IT artifacts. However, cross-sectional research designs are predominantly applied in the IS field up till now. This paper is therefore written not only to motivate the IS community to apply longitudinal research to time-variant IS phenomena but also to discuss common pitfalls. For this purpose, we outline various longitudinal studies and provide four guidelines that should be considered during their planning. In particular, common methodological issues like space and amount of repeated observations or attrition are discussed. Finally, an overview of common longitudinal research questions and corresponding methods of longitudinal analyses is provided.

PublicationPrivacy Through Multiple Lenses : Applying the St. Gallen Multi-Layered Privacy Interaction Framework (SG-PIF)(APC, 2015-10-25)This article puts the St. Gallen Multi-Layered Privacy Interaction Framework (SG-PIF) into action. The SG-PIF aims to conceptualize privacy as an outcome of various aspects of life and society. Different levels of interaction between individuals' privacy behavior, understood as a decision-making process on whether to disclose personal information, and their environment are subject of investigation. Those layers include the personal level, organizations, society at large and the government. Thus the SG-PIF includes not only psychological aspects of privacy but also the economic, social, cultural, and legal factors that affect individual decision-making processes. The focus of the framework rests on the interaction of these layers or the reciprocal nature of them and the analysis of the impact on individual privacy behavior (Section 2). We use two case-studies to demonstrate how the SG-PIF can be applied to structure the analysis of privacy-related phenomena. The first case study treats the privacy-intrusive practice of email tracking (Section 3). The second one looks at the more futuristic developments in robotics and the impact on individual privacy (Section 4).
