Egon Franck, C Opitz, T Pudack, Zum Kalkül der Personalauswahl in Topmanagement-Beratungen: Werden die besten Berater Partner?, Die Unternehmung, Vol. 56 (1), 2002. (Journal Article)
Der vorliegende Beitrag untersucht das Beförderungskalkül von Topmanagement-Beratungen. Wir zeigen, dass die Auswahl von Kandidaten durch die spezifischen Produktionsbedingungen, unter denen Beratungen agieren, beeinflusst wird. Entzieht sich die Arbeit von Partnern einer unmittelbaren Beobachtbarkeit durch den Klienten und sind die angebotenen Beratungsdienste Vertrauensgüter, ist zu erwarten, dass gerade nicht die besten Berater zu Partnern gewählt werden. |

Egon Franck, Zur Verantwortung des Verwaltungsrates aus ökonomischer Sicht, Die Unternehmung, Vol. 56 (4), 2002. (Journal Article)
Die Frage nach der Verantwortung des Verwaltungsrates ist auch aus der ökonomischen Sicht, die durch eine Argumentation mit ausschliesslich an ihrem Eigennutz orientierten Akteuren hervorsticht, nicht so eindeutig zu beantworten, wie das üblicherweise unterstellt wird. Um das zu zeigen, wird die Frage hintereinander in drei unterschiedlichen, aber in sich jeweils konsistenten ökonomischen Problemzuschnitten aufgeworfen und diskutiert. Die aus den einzelnen Problemzuschnitten ableitbaren ökonomischen Funktionsmetaphern für den Verwaltungsrat - Managermonitor, Versicherungsaufsicht, Mitspracheforum für alle ungeschützten Halter von Residualansprüchen - werfen auch unterschiedliche Schlaglichter auf die Verantwortungsfrage. Um sich bei der Konzeption ihres Verwaltungsrates an jener Funktionsmetapher orientieren zu können, die ihrer Situation angemessen ist, sollten die Gestaltungsfreiräume der Unternehmen nicht durch zu strenge Corporate Governance-Regulierungen eingeschränkt werden. |

M Kosfeld, Why shops close again: An evolutionary perspective on the deregulation of shopping hours, European Economic Review, Vol. 46 (1), 2002. (Journal Article)
This paper introduces a new perspective on the deregulation of shopping hours based on ideas from evolutionary game theory. We study a retail economy where shopping hours have been deregulated recently. It is argued that first, the deregulation leads to a coordination problem between store owners and customers, and second, the ‘solution’ to this problem depends on the specific cost structure of stores and the preferences of customers. In particular, it may happen that, even if extended shopping hours are Pareto efficient, stores and customers do not succeed in coordinating on this equilibrium. The analysis explains the observation in Germany, where shopping hours have been deregulated recently, that store owners tend to go back to the former shopping hours again. Moreover, it emphasizes the important role of advertisement campaigns as a signalling device. |

Beat Hotz-Hart, Carsten Küchler, Ausblick auf eine Innovationspolitik der Schweiz, Die Volkswirtschaft, Vol. 75 (12), 2002. (Journal Article)
Wie in allen hoch entwickelten Volkswirtschaften ist die Sicherung von Wohlstand und Lebensqualität in der Schweiz nur möglich, sofern die Unternehmen im globalen Innovationswettbewerb erfolgreich sind. Bildung, Forschung und Technologie kommt deshalb eine überragende Bedeutung zu. Ebenso wichtig sind die Wechselwirkungen an den Schnittstellen von Wissenschaft, Technik, Berufsbildung, Unternehmen und internationalen Netzwerken. Die Herausforderungen und Chancen des Innovationswettbewerbs betreffen nicht nur einige Pionierfirmen, sondern die Lebensumstände aller in der Schweiz lebenden und arbeitenden Menschen. Ziel der Innovationspolitik ist es, die Innovationsfähigkeit des gesamten Wirtschaftsstandorts Schweiz sicherzustellen beziehungsweise zu erhöhen. |

Christian Ewerhart, Backward induction and the game-theoretic analysis of chess, Games and Economic Behavior, Vol. 39 (2), 2002. (Journal Article)
The paper scrutinizes various stylized facts related to the minmax theorem for chess. We first point out that, in contrast to the prevalent understanding, chess is actually an infinite game, so that backward induction does not apply in the strict sense. Second, we recall the original
argument for the minmax theorem of chess – which is forward rather than backward looking. Then it is shown that, alternatively, the minmax theorem for the infinite version of chess can be reduced to the minmax theorem of the usually employed finite version. The paper concludes with a comment on Zermelo’s (1913) non-repetition theorem. |

H Egger, P Egger, How international outsourcing drives up Eastern European wages, Weltwirtschaftliches Archiv (Review of World Economics), Vol. 138 (1), 2002. (Journal Article)
This paper analyzes the effects of intermediate goods trade on the development of real wages in Central and Eastern European manufacturing. The empirical findings show that world exports in intermediate goods of the CEEC exhibit a negative impact on wages, and imports a positive one. Since 1993, intermediate goods trade between the EU and the CEEC accounted for an increase in wages being most pronounced in Slovakia, Poland and the Czech Republic. |

Dario Bonato, Peter Zweifel, Information about multiple risks: the case of building and content insurance, Journal of Risk and Insurance, Vol. 69 (4), 2002. (Journal Article)
Insurers traditionally use risk-specific characteristics of insureds to classify them according to risk. In this article, the practical relevance of information about multiple risks is demonstrated for the case of content insurance of a Swiss company. Two types of such information prove important: information about "spillover moral hazard" caused by mandated prevention affecting preventive effort in an unregulated line, and information about "common impulses" reflected in the loss experience of related lines. Both contribute to an improved prediction of loss probability. |

H Egger, International outsourcing in a two-Sector Heckscher-Ohlin model, Journal of Economic Integration, Vol. 17 (4), 2002. (Journal Article)
This paper analyzes the distributional effects of international outsourcing in a two sector Heckscher-Ohlin type model if both sectors get economical access to cost-saving international outsourcing. Thereby, it is shown that if both sectors are engaged in international outsourcing in equilibrium, the cost-saving effects of outsourcing as well as the factor contents of the outsourced fragments are relevant for the factor price effects. Concerning the Pareto-criterion the main finding is that a Pareto-improving factor price impact of international outsourcing cannot be excluded from a theoretical point of view. |

Christian Ewerhart, Iterated weak dominance in strictly competitive games of perfect information, Journal of Economic Theory, Vol. 107 (2), 2002. (Journal Article)
We prove that any strictly competitive perfect-information two-person game with n outcomes is solvable in n−1 steps of elimination of weakly dominated strategies— regardless of the length of the game tree. The given bound is shown to be tight using a variant of Rosenthal's centipede game. |

Sandra Nocera, Dario Bonato, Harry Telser, The contingency of contingent valuation: how much are people willing to pay against Alzheimer's disease?, International Journal of Health Care Finance and Economics, Vol. 2 (3), 2002. (Journal Article)
The present work focuses on the choice of the elicitation technique within a contingent valuation (CV) framework. We simultaneously apply three different elicitation techniques to elicit willingness-to-pay (WTP) values for three programs against Alzheimer's disease. First, the dichotomous choice approach is used, which is the standard procedure. However, giving respondents only a yes/no response alternative seems to result in overestimated WTP values. Therefore, we secondly apply the dissonance-minimizing format which screens respondents for their preferences and thus avoids possible yea-saying and protest answers against the payment vehicle. The third format, a modified version of the payment card, allows respondents to express a level of voting certainty and to make less of a commitment. With our findings we show that a well-designed CV method is a suitable instrument for helping decision makers in the health care sector and that the Swiss population favors highly a program which improves the situation of informal caregivers. |

H Egger, Unemployment may be lower if unions bargain over wages and employment, Labour, Vol. 16 (1), 2002. (Journal Article)
This paper addresses the question under which circumstances unemployment can be lower if unions bargain over wages and employment in a general equilibrium framework. Thereby, it turns out that the unemployment rate may negatively depend on the wage rate, if the unemployment compensation scheme contains a constant real term in addition to the replacement ratio component. This is, compared with a pure replacement ratio scheme, the more plausible formalization of the real world’s compensation systems, at least for European countries. Besides the theoretical analysis, the paper also derives political implications by identifying the relevant parameters for the decision on whether weakening unions will be a good strategy for an economy to overcome its unemployment problem. |

Engin Kirda, Pascal Fenkam, Gerald Reif, Harald Gall, A service architecture for mobile teamwork, In: SEKE '02: Proceedings of the 14th international conference on Software engineering and knowledge engineering, ACM, 2002. (Conference or Workshop Paper)
Mobile teamwork has become an emerging requirement in the daily
business of large enterprises. Employees collaborate across locations
and need support while they are on the move. Business
documents (artifacts) and expertise need to be shared independent
of the actual location or connectivity (e.g., access through a mobile
phone, laptop, Personal Digital Assistant, etc.) of employees.
Although many collaboration tools and systems exist, most do
not deal with new requirements such as locating artifacts and experts
through distributed searches, advanced information subscription
and notification, and mobile information sharing and access.
The MOTION service architecture that we have developed supports
mobile teamwork by taking into account the different connectivity
modes of users, provides access support for various devices such
as laptop computers and mobile phones, and uses XML meta-data
and the XML Query Language (XQL) for distributed searches and
subscriptions. In this paper, we describe the architecture and the
components of our generic MOTION service platform for building
collaborative applications. The MOTION Teamwork Services
Components are currently being evaluated in two industry casestudies. |
