For many services, consumers can choose among a range of optional tariffs that differ in their access and usage prices. Recent studies indicate that tariff-specific preferences may lead consumers to choose a tariff that does not minimize their expected billing rate. This study analyzes how tariff-specific preferences influence the responsiveness of consumers’ usage and tariff choice to changes in price. We show that consumer heterogeneity in tariff-specific preferences leads to heterogeneity in their sensitivity to price changes. Specifically, consumers with tariff-specific preferences are less sensitive to price increases of their preferred tariff than other consumers. Our results provide an additional reason why firms should offer multiple tariffs rather than a uniform nonlinear pricing plan to extract maximum consumer surplus.
We analyze and compare the social, cultural and historical determinants that influence the international competitiveness of China and India. Starting with the discussion why pure economic determinants cannot solely explain a country's competitiveness, we will analyze previous qualitative research and evaluate quantitative data to assess which country has more favorable socio-economic factors influencing its economic performance in the long run.
The aim of the following paper is to examine the complementarities (and divergences) between the paleoliberal Adam Smith and the ordoliberal Walter Eucken. Following the hypothesis that Smith is among the forerunners and predecessors of Ordoliberalism and Social Market Economy, we try to provide the reader with an insight into the socio-political philosophy of Smith and Eucken pointing at similarities and differences alike. Therefore, we base our examination on a systematic primary source text analysis comparing the books and essays written by Eucken and Smith. The paper tackles these questions in two main steps: The first part highlights Smith's and Eucken's complex and interdependent system of natural liberty. The second section reviews Smith's and Eucken's philosophy of the state.
An information system is more than just the information technology; it is the system that emerges from the complex interactions and relationships between the information technology and the organization. However, what impact information technology has on an organization and how organizational structures and organizational change influence information technology remains an open question. We propose a theory to explain how communication structures emerge and adapt to environmental changes. We operationalize the interplay of information technology and organization as language communities whose members use and develop domain-specific languages for communication. Our theory is anchored in the philosophy of language. In developing it as an emergent perspective, we argue that information systems are self-organizing and that control of this ability is disseminated throughout the system itself, to the members of the language community. Information technology influences the dynamics of this adaptation process as a fundamental constraint leading to perturbations for the information system. We demonstrate how this view is separated from the entanglement in practice perspective and show that this understanding has far-reaching consequences for developing, managing, and examining information systems.
Theory building is not only underdeveloped in IT services management research, but in
general in IS. Given the paradigm shift that comes from the development away from a
networked economy towards a network economy, the lack of spending enough attention to
theorizing in IS becomes even more obvious. In the light of other "megatrends" in IS
research, such as the increasing professionalization and use of statistical methods and the
exploitation of extremely large sets of data (often harvested from social media sites), we
might lose interest in theorizing in the presence of the tremendous amount of available
empirical data. In this position paper, the author advocates that services science researchers
should focus on rigor and relevance in their research approaches.
Immer auf den ersten Rängen : Leibniz-Preis für den Frankfurter Volkswirtschaftler Roman Inderst
(2010)
Wenn es um Superlative geht, dann steht der 40-jährige Prof. Roman Inderst immer ganz oben auf dem Treppchen: jung und schon auf den ersten Rängen unter den Top Ten der europäischen Wirtschaftswissenschaftler. Und am 15. März wurde er auch noch als jüngster unter den zehn Preisträgern mit dem wichtigsten deutschen Forschungspreis, dem mit 2,5 Millionen Euro dotierten Gottfried Wilhelm Leibniz-Preis 2010, ausgezeichnet.
Plattformen für Social Communities im Internet, wie Facebook, StudiVZ und XING, haben in den vergangenen Jahren rasant an Popularität gewonnen. Auf ihnen versammeln sich bereits heute Millionen von Nutzern weltweit. Sie verbinden sich über virtuelle Freundeslisten und tauschen sich über gemeinsame Interessen und Aktivitäten aus. Immer häufger werden dazu auch mobile Endgeräte wie Handys verwendet, erlauben diese doch ständig in Kontakt mit der Community zu bleiben. Allerdings wollen viele Nutzer längst nicht jedem Mitglied einer Community alles preisgeben. Doch wie lässt sich die Privatsphäre in solchen Communities besser schützen? Dieser Frage geht das Forschungsprojekt PICOS nach.
