 Helmut Max Dietl, Martin Grossmann, Markus Lang, Simon Wey, Incentive effects of bonus taxes, In: 15th Annual Conference of "The International Society for New Institutional Economics (ISNIE)", UZH Business Working Paper Series. 2011-06-16. (Conference Presentation)
Several countries have implemented bonus taxes for corporate executives in response to the financial crisis of 2007-2010. Using a principal-agent model, this paper analyzes how bonus taxes affect the agent's effort, compensation package, tax revenue and social welfare. We show that, contrary to its intention, a bonus tax may even increase the bonus rate and decrease the fixed salary. In addition, a bonus tax can induce the principal to pay higher bonuses even though the agent's effort always decreases. Finally, a bonus tax decreases social welfare unless the social planner places a sufficiently high weight on tax revenue. |

Guilherme Sperb Machado, Burkhard Stiller, An SLA system support system for cloud computing, In: 5th International Conference on Autonomous Infrastructure, Management, and Security (AIMS 2011), 2011-06-15. (Conference or Workshop Paper published in Proceedings)
Nowadays, even with the existence of many Cloud Providers (CP) in the market, it is still impossible to see CPs who guarantee, or at least offer, an SLA specification to Cloud Users (CU) interests: not just offering percentage of availability, but also guaranteeing specific performance parameters for a certain Cloud application. Due to (I) the huge size of CPs' IT infrastructures and (2) the high complexity with multiple inter-dependencies of resources (physical or virtual), the estimation of specific SLA parameters to compose Service Level Objectives (SLOs) with trustful Key Performance Indicators (KPis) tends to be inaccurate. This paper proposes the initial design and preliminary approach tor an SLA Support System for CC (SLACC) in order to estimate in a formalized methodology - based on available CC infrastructure parameters - what CPs will be able to offer/accept as SLOs or KP!s and, as a consequence, which increasing levels ofSLA specificity for their customers can be reached. |

Dorit Assaf, Rolf Pfeifer, EmbedIT - An Open Robotic Kit for Education, In: Research and Education in Robotics - EUROBOT 2011, Springer, Berlin, Heidelberg, Germany, 2011. (Conference or Workshop Paper published in Proceedings)
Robots have often been used as an educational tool in class to introduce kids to science and technology, disciplines that are affected by decreasing enrollments in universities. Consequently, many robotic kits are available off-the-shelf. Even though many of these platforms are easy to use, they focus on a classical top-down engineering approach. Additionally, they often require advanced programming skills. In this paper we introduce an open robotic kit for education (EmbedIT) which currently is under development. Unlike common robot kits EmbedIT enables students to access the technical world in a non-engineering focused way. Through a graphical user interface students can easily build and control robots. We believe that once fascination and a basic understanding of technology has been established, the barrier to learn more advanced topics such as programming and electronics is lowered. Further we describe the hardware and software of EmbedIT, the current state of implementation, and possible applications. |

Stefano Battiston, Stefania Vitali, Geography versus topology in the european ownership network, New Journal of Physics, Vol. 13, 2011. (Journal Article)
In this paper, we investigate the network of ownership relationships among European firms and its embedding in the geographical space. We carry out a detailed analysis of geographical distances between pairs of nodes, connected by edges or by shortest paths of varying length. In particular, we study the relation between geographical distance and network distance in comparison with a random spatial network model. While the distribution of geographical distance can be fairly well reproduced, important deviations appear in the network distance and in the size of the largest strongly connected component. Our results show that geographical factors allow us to capture several features of the network, while the deviations quantify the effect of additional economic factors at work in shaping the topology. The analysis is relevant to other types of geographically embedded networks and sheds light on the link formation process in the presence of spatial constraints. |

Susanne Schmidt-Rauch, Philipp Nussbaumer, Putting Value Co-Creation into Practice: A Case for Advisory Support, In: European Conference on Information Systems 2011, Helsinki, 2011. (Conference or Workshop Paper published in Proceedings)
The concept of value co-creation and its notion of the customer as co-creator of value have gained much academic interest, notably in marketing and operations research. While several competing perspectives have been conceptually discussed in literature, research on the practical implications of value co-creation is scarce. Using the example of sales-oriented advisory, we show gaps between existing co-creation concepts and current practice in five problem areas. We develop four general solution perspectives on the advisor-client encounter as guidelines to overcome these gaps and discuss design requirements of their technological instantiations in advisory support systems. We present exemplary implementations of such systems in two domains: travel counseling and financial advisory. Revealing the practical implications of value co-creation on advisory encounters, these examples also demonstrate that the solution perspectives have to be implemented quite differently for individual domains. |

Research into customer satisfaction of advisory services provided by financial service providers (FSPs) indicates a history of problems that originated well before the current financial crisis. As part of a research program into the design of advisory processes and supporting IT tools, we conducted a survey of affluent Swiss investors that was focused on their information search behavior when preparing to make an investment decision. Results show that advisory services are used at a later stage in the investment decision process, after Internet-based professional sources, media and personal contacts. In order for advisory services to become a preferred information source amongst customers, FSPs need to increase their accessibility, raise their level of perceived trust, and enhance the customer’s access to a diverse range of trusted information sources in the advisory process. |

Anselm Jakob Schneider, Principles for designing superior stakeholder organizations i: reconciling efficiency and legitimacy by communication, In: 1st Interdisciplinary Conference On Stakeholders, Resources And Value Creation. 2011. (Conference Presentation)
In this article I analyze the role of communication for organizational efficiency and organizational legitimacy. The main point is that under conditions of environmental complexity and dynamics characteristic for economic activity in a globalized economic system, business firms need to extensively engage in communicative processes with their stakeholders to obtain information necessary for organizational survival. In general, such processes are also suitable to generate organizational legitimacy, which is becoming increasingly central to the successful management of business firms. By introducing the concept of multifunctional communication, opportunities and limits of the simultaneous generation of organizational efficiency and organizational legitimacy by means of stakeholder communication are discussed. |

The growth of online social networks and the decreasing effectiveness of traditional marketing have lead to a surge of interest in using such networks for marketing purposes. Actors embedded in such social networks are interested in understanding how to leverage the interactions and relationships among network members to increase their popularity and garner online success. In this paper we analyze how the network activities that an actor engages in influences the actor's egocentric positions within the network and how such activities in combination with these network positions eventually impact marketing success. In particular, we study how a network of music artists can drive music downloads by engaging in active communication and building of friendship activities. Our sample consists of a set of 440 music artists who actively operate profiles on two independent online social network platforms at the same time. Personal network information on both platforms is tracked monthly over a period of one year. As network positions are endogeneous, and instrumental variables are not available readily, we use a latent instrumental variable approach to model the endogeneity of multiple network influence variables. Our results indicate that online success is determined by both the social network structure and networking activities of the music artists rather than by their outside popularity. |
