    The Business Value of IT in Light of Prospect Theory
    (Business & Information Systems Engineering: Vol. 57, No. 5, 2015) Afflerbach, Patrick
    A key problem with IT decision-making is that the real value contributions of IT projects are unknown ex-ante to their executions. Thus, an organization has to rely on the expectations and perceptions of its decision makers. Moreover, these perceptions are prone to biases and display only a transfigured or irrational image of reality. This paper examines how these biases are related to the business value of IT (BVIT) and how IT decision-making can be rationalized. To this aim, a model is set up based on prospect theory, which is a frequently cited theory from behavioral economics used to descriptively analyze human value perception under risk. Applying the results found via prospect theory to IT decisions, the “perceived” BVIT is quantified and analyzed. Based on the model, the paper shows that the irrationalities rooted in human value perception provide explanations for two central paradoxes of IT. First, it reveals that they cause a disparity between the anticipated value-adding effects of IT and the actual measured outcomes, reflecting a famous observation within BVIT research known as the “productivity paradox of IT.” Second, recent studies show that IT increases the operational efficiency and competitiveness of organizations. However, only the operational effects are perceived in practice. In the paper, this one-sided perception is referred to as the “perception paradox of IT”. It is ultimately concluded that a rethinking of the position of IT within modern organizations and the establishment of suitable corporate governance mechanisms can resolve these issues, avoid irrationalities, and positively influence the performance impacts of IT.

    The Economics of Multi-Hop Ride Sharing
    (Business & Information Systems Engineering: Vol. 57, No. 5, 2015) Teubner, Timm; Flath, Christoph M.
    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, ubiquity of digital and mobile technology and user habituation to peer-to-peer services and electronic markets have resulted in particular growth in recent years. This paper explores the novel idea of multi-hop ride sharing and illustrates how information systems can leverage its potential. Based on empirical ride sharing data, we provide a quantitative analysis of the structure and the economics of electronic ride sharing markets. We explore the potential and competitiveness of multi-hop ride sharing and analyze its implications for platform operators. We find that multi-hop ride sharing proves competitive against other modes of transportation and has the potential to greatly increase ride availability and city connectedness, especially under high reliability requirements. To fully realize this potential, platform operators should implement multi-hop search, assume active control of pricing and booking processes, improve coordination of transfers, enhance data services, and try to expand their market share.

    When ‘Just’ is Just Not Enough
    (Business & Information Systems Engineering: Vol. 57, No. 5, 2015) Krämer, Jan; Wiewiorra, Lukas
    Although Internet service providers (ISPs) are technically capable as well as legally allowed to offer non-neutral Internet access services, where the data flows of customers who pay a premium are prioritized over others, such an access service is currently not offered by ISPs. We argue that ISPs are hesitant to tap the price discrimination potential of prioritized Internet access services, because in the context of the ongoing public debate on net neutrality (NN), their customers would consider such differentiation unjust. In a representative survey among German Internet access customers, we find that the customers’ perceptions of justice as well as the framing of the mechanism by which prioritized Internet access is provided are indeed decisive for whether customers would prefer this access regime over NN. In particular, we find that perceptions of distributive and procedural justice influence customers’ choice for non-neutral Internet access. Moreover, customers are more likely to accept a regime that offers an absolute rather than a relative prioritization of data flows.
