D Peric, Thomas Bocek, Fabio Victora Hecht, D Hausheer, Burkhard Stiller, Brief Announcement: The Design and Evaluation of a Distributed Reliable File System, In: 11th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS 2009), Springer, Lyon, France, 2009-11-03. (Conference or Workshop Paper published in Proceedings) Network file systems provide access to data in a networked environment. If such systems operate in a client-server (C/S) mode, e.g., NFS (Network File System) or SMB (Server Message Block), issues concerning the scalability, the presence of a single point of failure, and fault tolerance emerge. Scalability issues, such as coping with an increasing number of clients, need to be addressed, since bandwidth on the server side may be limited and expensive. Peer-to-peer (P2P) systems are, in contrast to C/S systems, fault-tolerant, robust, and scalable. Distributed file systems based on P2P networks can help to avoid such problems. Besides, P2P systems are self-organizing, requiring less management, thus reducing maintenance costs.

Ulrike Malmendier, Geoffrey Tate, Superstars CEOs, Quarterly Journal of Economics, Vol. 124 (4), 2009. (Journal Article) Compensation, status, and press coverage of managers in the United States follow a highly skewed distribution: a small number of “superstars” enjoy the bulk of the rewards. We evaluate the impact of CEOs achieving superstar status on the performance of their firms, using prestigious business awards to measure shocks to CEO status. We find that award-winning CEOs subsequently underperform, both relative to their prior performance and relative to a matched sample of non-winning CEOs. At the same time, they extract more compensation following the awards, both in absolute amounts and relative to other top executives in their firms. They also spend more time on public and private activities outside their companies, such as assuming board seats or writing books. The incidence of earnings management increases after winning awards. The effects are strongest in firms with weak corporate governance. Our results suggest that the ex post consequences of media-induced superstar status for shareholders are negative.
Dennis L Gärtner, Daniel Halbheer, Are there waves in merger activity after all?, International Journal of Industrial Organization, Vol. 27 (6), 2009. (Journal Article) This paper investigates the merger wave hypothesis for the US and the UK employing a Markov regime-switching model. Using quarterly data covering the last 30 years, for the US, we identify the beginning of a merger wave in the mid 1990s but not the much-discussed 1980s merger wave. We argue that the latter finding can be ascribed to the refined methods of inference offered by the Gibbs sampling approach. As opposed to the US, mergers in the UK exhibit multiple waves, with activity surging in the early 1970s and the late 1980s.
Utpal M Dholakia, Vera Blazevic, Caroline Wiertz, René Algesheimer, Communal Service Delivery: How Customers Benefit from Participation in Firm-hosted Virtual P3 Communities., Journal of Service Research, Vol. 12 (2), 2009. (Journal Article) Firm-hosted virtual peer-to-peer problem solving (P3) communities offer a low-cost, credible, and effective means of delivering education and ongoing assistance services to customers of complex, frequently evolving products. Building upon the social constructivist view on learning and drawing from literature on the firm-customer relationship in services marketing, we distinguish between functional and social benefits received by P3 community participants and study the central role of learning in influencing these benefit perceptions. The proposed model is tested on data gathered from 2,299 active members of a P3 community hosted by a global online auction firm, and the framework’s generalizability is demonstrated using a sample of 204 members of a global B2B software firm’s P3 community. Based on the results, specific recommendations are provided to marketers interested in implementing service support programs via customer communities, and future research opportunities are explored.
M Möller, A Höllbacher, Die deutsche Börsen- und Indexlandschaft und der Markt für Abschlussprüfungen: eine empirische Studie zu langfristigen Konzentrationstendenzen auf dem Wirtschaftsprüfermarkt, Die Betriebswirtschaft (DBW), Vol. 69 (6), 2009. (Journal Article) Die in den letzten Jahren veröffentlichten Studien zur Anbieterkonzentration auf dem Markt für Abschlussprüfungen in Deutschland stellten ein hohes Maß an Konzentration fest. Die vorgelegten Arbeiten beschränkten sich dabei i.d. R. auf eine statische oder komparativ-statische Analyse und damit auf eine Konzentrationsmessung einzelner Jahre. Ziel des vorliegenden Beitrags ist eine umfassende Konzentrationsanalyse für Abschlussprüfungen bei im DAX geführten Unternehmen im Zeitraum 1997-2007. Hierbei lässt sich zeigen, dass bei diesen Indexwerten der deutschen Börsenlandschaft weiterhin von einer fortschreitenden Konzentration des Prüfungsmarktes - allerdings verbunden mit einer Tendenz zur Homogenisierung innerhalb der Gruppe der "Big 4"-Prüfungsgesellschaften - gesprochen werden kann.
