Liking what others “Like”: using Facebook to identify determinants of conformity

In this paper we explore the micro-level determinants of conformity. Members of the social networking service Facebook express positive support to content on the website by clicking a Like button. We set up a natural field experiment to test whether users are more prone to support content if someone else has done so before. To find out to what extent conformity depends on group size and social ties we use three different treatment conditions: (1) one stranger has Liked the content, (2) three strangers have Liked the content, and (3) a friend has Liked the content. The results show that one Like from a single stranger had no impact. However, increasing the size of the influencing group doubled the probability that subjects expressed positive support. Friendship ties were also decisive. People were, on average, four times more likely to press the Like button if a friend, rather than a stranger, had done so before them. The existence of threshold effects in our experiment clearly shows that both group size and social proximity matters when opinions are shaped.     

Grounded Theory und ihre bisherige Anwendung in der empirischen Controlling- und Rechnungswesenforschung

Zusammenfassung  Die Bildung von Forschungshypothesen ist zwar immer ein kreativer, sollte aber gleichzeitig kein unsystematischer Prozess sein. Im vorliegenden Artikel liegt der Fokus auf der Methodenunterstützung des Entdeckungszusammenhangs. Die Methode der Grounded Theory bietet einen Bezugsrahmen für qualitative empirische Studien, mit dem Theorien entwickelt werden, die aus dem Textmaterial zu begründen sind. Eine Literaturanalyse verdeutlicht, dass das Potenzial dieser Methode bisher in der Controlling- und Rechnungswesenforschung weitgehend ungenutzt bleibt. Anhand einer Diskussion empirischer Studien, welche auf die Methode zurückgreifen, werden Anwendungsm?glichkeiten der Grounded Theory für diese Disziplinen aufgezeigt.

Summary  Creating research hypotheses is always a creative but not necessarily an unsystematic process. In our study we introduce a method supporting the logic of discovery. The grounded theory approach provides a framework for a systematic development of theories emerging from empirical data. A literature review stresses that the potential of the method so far is unused in accounting research. The grounded theory approach is introduced to support empirical work within this research field. Options for an application of the method in accounting research are shown by the means of a discussion of empirical studies. Furthermore the reader gets hints for reference studies.

     

Die Wirkung der Positionierung eines Zulieferunternehmens auf das Vertrauen des Kunden

Zusammenfassung Aus bisherigen Studien lassen sich kaum Handlungsempfehlungen ableiten, welche Positionierung eines Zulieferunternehmens sich besonders vorteilhaft auf das Vertrauen eines Kunden auswirkt. Im vorliegenden Beitrag werden die Wirkungen von vier Positionierungsstrategien, die Zulieferunternehmen zur Verfügung stehen, auf das Vertrauen ihrer Abnehmer aus der Automobilindustrie untersucht. Diese Strategien bestehen in der Anpassung an Kundenprozesse, in Serviceorientierung, in Flexibilit?t und in der Verwendung von Kompetenzsignalen gegenüber dem Markt. Wir zeigen, dass die Anpassung an Kundenprozesse auf Grund der hohen Spezifit?t der damit verbundenen Investitionen die st?rkste positive Wirkung auf das Vertrauen des Kunden aufweist und dass Kompetenzsignale gegenüber dem Markt kein geeignetes Instrument zur F?rderung des Kundenvertrauens sind, wenn das Zulieferunternehmen für den Abnehmer eine hohe Bedeutung besitzt.

The effects of a supplier’s positioning strategy on buyers’ trust

Summary Many studies have identified measures that are able to enhance partners’ trust in business-to-business relationships. However, it is not known which measures are more effective than others or under which conditions certain measures might be helpful or not. In the present study the effects of four possible positioning strategies on buyer’s trust are examined. The positioning strategies considered here are the supplier’s adaptations regarding its customer’s processes, its service orientation, its flexibility, and market-signals stressing the supplier’s competence. We found that, due to the high specificity of the required investments, adaptations of the supplier’s processes are the strongest instrument to enhance buyers’ trust relative to the other three strategies. We could also show that investments in market signals stressing the supplier’s competence are not effective if the supplier is of high importance to the customer.

     

Ideas and actions: Justification and hypocrisy as alternatives to control

Popular hierarchical models of organizations and societies contain two assumptions about the relation between the ideas of constituencies and leaders on the one hand and organizational, and societal actions on the other: that ideas and actions are consistent, and that ideas control actions. In this article some practical difficulties in achieving consistency and control are discussed. Consistency is difficult to achieve when what can be done cannot be said and vice versa, and control is difficult to combine with consistency when ideas change more rapidly than action. The difficulty of achieving consistency and control can be partially overcome by combining ideas and actions in two other ways. One combination involves justification, and the other hypocrisy.

Flexibility at different stages in the life cycle of projects: An empirical illustration of the “freedom to maneuver”

Many textbooks on project management present illustrations concerning the relative size of project attributes during different project phases. The derived models all have attributes in common, such as uncertainty, significance of decisions, and degree of freedom to maneuver, that are typically high in the beginning of the project and low in the end. At the same time, variables such as the accumulated cost and available information begin at low levels and end up at a high level at the end of the project. Based on empirical data from projects, this paper illustrates and quantifies one of these attributes, the freedom to maneuver, in different project phases.     

Nash-equilibria in a heterogeneous oligopoly with fuzzy information

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification: D43, D80, L13We wish to thank Bernhard F.
