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. |

Robertas Zubrickas, How exposure to markets can favor inequity-averse preferences, In: Conference on Rationality and Irrationality: Game-Theoretic and Other Perspectives, 2011-06-03. (Conference or Workshop Paper published in Proceedings)
This paper shows how non-individualistic preferences can be individual fitness maximizing in market-integrated societies. In the model, individuals share an endowment, which is used for consumption and/or purchase of goods on the external market. We show that inequity aversion about endowment distribution can be an optimal response to merchants' price discrimination. Then, assuming that increased consumption means increased individual fitness, we argue that evolutionary selection can favor inequity-averse preferences. We also argue that our model can explain the empirical finding of Henrich et al. (2004) about the positive effect of a society's exposure to markets on its members' sociality. |

Öktem Paslioglu, Der Effekt von (un-)erwarteten Ereignissen auf die Aktienrendite von börsenkotierten Fussballclubs, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2011. (Bachelor's Thesis)
Abstract
Es wird untersucht, ob (un-)erwartete Ereignisse einen Effekt auf die Aktienrendite von börsenkotierten
Fussballclubs haben. Als Ereignisse werden Spielergebnisse von Fussballclubs
definiert, die in der nationalen Ligameisterschaft erzielt wurden. Als Proxy für das Erwartungsmass
dienen die Wettquoten vor einem Ligaspiel. Für die Untersuchung dieser Forschungsfrage
werden eine Event Study und eine einfache Analyse anhand Durchschnittsrenditen
durchgeführt. Die Resultate der Untersuchung sind: Siege haben einen positiven Effekt
auf die Aktienrendite von Fussballclubs. Niederlagen und Unentschieden wirken sich negativ
aus, wobei der negative Effekt von Niederlagen grösser ist als der von Unentschieden. |

Enrico De Giorgi, Thierry Post, Loss Aversion with a State-Dependent Reference Point, Management Science, Vol. 57 (6), 2011. (Journal Article)
This study investigates reference-dependent choice with a stochastic, state-dependent reference point. The optimal reference-dependent solution equals the optimal consumption solution (no loss aversion) if the reference point is selected fully endogenously. Given that loss aversion is widespread, we conclude that the reference point generally includes an important exogenously fixed component. We develop a choice model in which adjustment costs can cause stickiness relative to an initial, exogenous reference point. Using historical U.S. investment benchmark data, we show that this model is consistent with diversification across bonds and stocks for a wide range of evaluation horizons, despite the historically high-risk premium of stocks compared to bonds. |

Armin Falk, Josef Zweimüller, Andreas Kuhn, Unemployment and Right-Wing Extremist Crime, Scandinavian Journal of Economics, Vol. 113 (2), 2011. (Journal Article)
It is frequently argued that unemployment plays a crucial role in the occurrence of right-wing extremist crimes (RECs). We test this hypothesis empirically using data from Germany. We find that right-wing criminal activities occur more frequently when unemployment is high. The substantial difference in the numbers of RECs occurring in the East and West German states can mostly be attributed to differences in unemployment. This finding reinforces the importance of unemployment as an explanatory factor for RECs, and it questions explanations based solely on the different socialization in former communist East Germany and the liberal West German states |

Anselm Jakob Schneider, Andreas Scherer, Polanyi reloaded - a historical perspective on the relationship between corporate responsibility and the welfare-state, In: 11th EURAM conference. 2011. (Conference Presentation)
This article argues that in the capitalist system of market economy, businesses contribute to the stabilization of society by way of activities that go beyond their economic engagement in markets. The analysis of the relationship between corporate nonmarket activities – corporate social engagement as well as political activities such as lobbying – and the modern welfare state suggests that both types of nonmarket activities can be conceived as intra-organizational realizations of the contradictory societal principles of economic liberalism and social protectionism. The combination of these varieties of corporate nonmarket activities and their underlying logics (instrumental logic in the case of political activities and prosocial logic in the case of social engagement) within a single framework contributes to the understanding of the dynamics and functions of the multiplicity of corporate activities by going beyond focusing on purely economic explanations. In addition, we emphasize the dangers of an instrumental approach to corporate social engagement. |
