 Ulrike Malmendier, Devin Shanthikumar, Are Small Investors Naïve About Incentives?, Journal of Financial Economics, Vol. 85 (2), 2007. (Journal Article)
Security analysts tend to bias stock recommendations upward, particularly if they are affiliated with the underwriter. We analyze how investors account for such distortions. Using the NYSE Trades and Quotations database, we find that large traders adjust their trading response downward. While they exert buy pressure following strong buy recommendations, they display no reaction to buy recommendations and selling pressure following hold recommendations. This “discounting” is even more pronounced when the analyst is affiliated with the underwriter. Small traders, instead, follow recommendations literally. They exert positive pressure following both buy and strong buy recommendations and zero pressure following hold recommendations. We discuss possible explanations for the differences in trading response, including information costs and investor naiveté. |

Ernst Fehr, Herbert Gintis, Human motivation and social cooperation: experimental and analytical foundations, Annual Review of Sociology, Vol. 33 (1), 2007. (Journal Article)
Since Durkheim, sociological explanations of social cooperation emphasize the internalization of values that induce norm compliance. Since Adam Smith, economic explanations of social cooperation emphasize incentives that induce selfish individuals to cooperate. Here we develop a general approach – the Beliefs, Preferences, and Constraints approach – showing that each of the above models is a special case. Our approach is based on
evidence indicating that pure Homo Sociologicus and pure Homo Economicus views are wrong. We show that self-regarding and norm-regarding actors coexist and that the available action opportunities determine which of these actor types dominates the aggregate level of social cooperation. Our approach contributes to the solution of long-standing problems, including the problems of social order and collective action, the determinants and consequences of social exchanges, the micro-foundations of emergent aggregate patterns of social interactions, and the measurement of the impact of cultural and economic practices on individuals’ social goals. |

Michael Imhof, Entwicklung eines RDF Parsers für transaktionsbasierte Daten, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2007. (Bachelor's Thesis)
Der Java RDF Parser (JRP) ist ein Programm zum Einlesen von Files im RDF
Format und Extrahieren von transaktionsbasierten Daten, die anschliessend in einer
Datenbank gespeichert werden können. Diese Arbeit handelt von der Entwicklung
von JRP und bietet dem Leser einen Einblick in das Design des Codes, das
Datenbank-Schema und die Anbindung sowie eine Evaluation von Jena, der Java
Library die fu?r das Parsen der Daten benutzt wird. Selbstverständlich wurde das
Programm mit realen Daten getestet und bewies auf diese Art und Weise seine
korrekte Funktionalität. Leider kann bis jetzt nichts u?ber die Skalierbarkeit des
Parsers gesagt werden, da fu?r die Performance Tests keine grossen Datensätze
vorhanden waren. The Java RDF Parser (JRP) is a program to read in files in RDF format and extract
transactional data from it that can be stored in a database afterwards. This thesis is
about the development of JRP and gives an insight into the design of the code, the
database schema and connection, as well as an evaluation of Jena, the Java library
that is used to parse the input files. Naturally, the program was tested with real data
and proved the desired functionality. Unfortunately, nothing can be said about the
scalability of the parser, because there were no large datasets available for
performance tests. |

Tobias Bannwart, Design and Prototypical Implementation of a Gird-Service Gateway for an A4C Client, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2007. (Bachelor's Thesis)
Kommunikationssysteme der heutigen Generation ben¨otigen starke Sicherheitsmechanismen um
ihren Benutzern einen vertrauenswerten Service anbieten zu k¨onnen. Das Akogrimo Projekt hat
sich zum Ziel gesetzt, eine Plattform f ¨ ur mobile Gridsysteme zu entwickeln, die neben den klassischen
AAA Konzepten zus¨atzliche Module f ¨ ur Auditing und Charging anbietet (A4C). Der Entwurf
von Akogrimo folgt dabei einer serviceorientierten Architektur (SOA), die existierende Implementation
eines Prototypen hingegen nicht. In dieser Arbeit wurde ein A4C Gateway erstellt,
dass die Konzepte der SOA erf ¨ ullt. Die Evaluation der Leistungsf¨ahigkeit ergab, dass durch die
SOA mit erheblich l¨angeren Zugriffszeiten von dreihundert Prozent Steigerung gerechnet werden
muss. Today’s communication systems are in need of strong security mechanisms, to be able to provide
their users with trustworthy services. The Akogrimo project decided to develop a platform for
mobile grid services, which offers not only the classical security modules for authentication, authorisation
and accounting but also extends them by adding two additional modules for auditing
and charging. The draft version of the developed platform follows an service-oriented architecture
(SOA), the existing implementation prototype however does not. The goal for this article is
therefore to present an A4C gateway that fulfills the SOA concepts. The evaluation of the performance
resulted in the finding, that by adding an additional SOAP-Layer, access times to the A4C
functionality raised in value by three-hundred per cent. |

Philippe Hungerbühler, The Influence of SPAM on Performance, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2007. (Bachelor's Thesis)
Almost every Internet user knows about the problem of SPAM. At work, especially, it costs time
to sort out irrelevant emails. This thesis deals with the problem of SPAM and its consequences
on productivity at work. For this reason an experiment has been conducted to examine the distraction
of SPAM and its perception. A few hypotheses, stated in advance, have been reviewed
on basis of this experiment. The results and the interpretation are presented and discussed in this
thesis. |

Stéphanie Eugster, Standardisierte Datentypen (Data Items) als integrierendes Element in einer komponenten-basierten Architektur, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2007. (Master's Thesis)
UBS Wealth Management and Business Banking (WM&BB) builds its software development on its component-based origins. The interface of these software components should therefore also be based on standardized data items. In this paper, the current situation is analyzed and the requirements according to standardized data-management are recorded and evaluated. The main problems are identified as fragmented configuration management and unsatisfactory metadata quality. The discussion shows that in regards to Front-End and communication problems, a solutions process is offered through the implementation of validators and mediators. For the most important requirements, a transformation plan is drafted. The proposed solution has been validated in assistance with a prototype. |
