IMAGE AND MISREPORTING

In this paper we analyze how image utility can lead to misreporting of private information in contexts where truthful reports maximize monetary outcomes. In a controlled experiment, subjects go through a series of quiz questions and subsequently report a performance measure. We vary whether reports are made to an audience or not. In an additional feedback treatment, reports are also stated to an audience and afterwards the experimenter publicly verifies whether reports were correct. We find that in the audience treatment, stated reports are significantly higher relative to the private treatment as well as the feedback treatment. Our findings suggest that overconfident appearance might be a consequence of social approval seeking.

Entrepreneurial Marketing in Online-Netzwerken

A growing number of professionals use online social networks (e.g., Xing or LinkedIn) for business reasons by specifically promoting themselves. Especially executives and entrepreneurs use business social networks as a marketing tool in order to manage their business contacts and, thus, positioning themselves as a brand. Using on Keller’s (1993) customer-based brand equity model, we focus on the special behavior of entrepreneurs in such social networks. Based on the a large data set from a leading social network, we empirically analyze whether entrepreneurs act differently than other users and whether this strategy pays off. Based on a SUR model, we determine what the drivers for entrepreneurs’ profile views and contacts are. The results show that entrepreneurs focus on communicating their intentions and competencies and engage actively in the community. Especially participating in user groups and attending community events are key drivers for success.     

Macroeconomic determinants of migration: the case of Germany, 1964-1988

Macroeconomic determinants of immigration are analysed with pooled cross-country and time series data on net immigration to Germany from European countries during 1964-1988.
Results demonstrate clearly that both high and low frequency determinants have been important. Long run trends are determined by the degree and speed of per capita income convergence between the sending and receiving countries, while year-to-year changes in net immigration flows are dominated by cyclical economic conditions.     

Effect of Level of Disaggregation on Conjoint Cross Validations: Some Comparative Findings*

Early formulations of conjoint models focused on part-worth estimation at the individual level. As the methodology's popularity grew so did industry demands for increasingly larger numbers of attributes and levels. In response to these demands, new approaches, based on partial or full data aggregation (such as clusterwise/latent class conjoint and choice-based conjoint), have appeared. This paper suggests that pooled-data models will often be successful in predicting market shares when researchers employ monotonic attributes. In these cases more of a good attribute (or less of a bad attribute) is always more preferred. In the more realistic case, in which some of the attributes may be nonmonotonic, we find that data aggregation does not predict holdout sample preferences as well as individual part-worth models.     

More Participation,Happier Society? A Comparative Study of Civil Society and the Quality of Life

A ‘good society’ has recently been portrayed as one in which citizens engage in voluntary associations to foster democratic processes. Arguably, such a good society is considered as one where people are content with their own lives as well as public life. We consider whether participation in civil society leads to more satisfied individuals on the one hand and a better evaluation of society at a country level on the other. With data from the first round of the European Social Survey, we illustrate that participation in voluntary associations not only depends on individual characteristics, but that there is a clear country-level effect on civil society. This can be explained with measures of quality of society after socio-demographic determinants have been controlled for. Nonetheless, it remains difficult to say what comes first: a ‘good society’ or a thriving civil society.
