Whereas the supply of redistribution is relatively easy to measure, the determinants of the demand for redistribution are controversially discussed in international literature. Economic theory typically models redistribution as the result of a voting mechanism; this is only inadequately reflected by the existing empirical studies. In general, these studies use survey data and are therefore not able to predict individuals' decision making under the restriction of a budget constraint. This study aims at eliciting preferences for redistribution in Germany with the help of a Discrete Choice Experiment (DCE), based on a representative sample of 1,538 individuals. A DCE solves the aforementioned problems by forcing individuals to overcome trade-offs. The results show a strong preference for redistribution that overshoots the current level. Considering socio-demographic characteristics, the results contradict the Meltzer-Richard-Model and the POUM hypothesis, while Piketty's learning model is strongly supported by the data.Keywords: redistributive preferences, social mobility, median voter.

MotivationIn Germany, as in most industrialized countries, income inequality has steadily increased (see OECD 2011a, 2011b). The government tries to affect the pre-tax income distribution by collecting taxes and granting monetary transfers. By doing so, income inequality between pre-tax and net incomes is reduced by about 40 % on average in Germany as measured by the Ginicoefficient (see Pfarr 2013, p. 3, SVR 2011. This strong governmental involvement calls for a detailed analysis of redistributive policies. Whereas the supply of redistribution is relatively easy to measure, the determinants of the demand for redistribution are controversially discussed in international literature. According to Alesina and Glaeser (2004), most studies cover economic, institutional or behavioral factors. This study concentrates on the economic factors encompassing the traditional Meltzer-Richard hypothesis and the social mobility hypothesis.In economic theory, redistribution is usually interpreted as the result of a voting mechanism.Individuals express their demand for redistribution in line with their preferences, and political parties act as the supplier thereof. Most of the existing literature concentrating on the determinants for individuals' redistributive preferences is not able to differentiate between these two sides. Moreover, as these studies use survey data, they cannot predict individuals' decision making under the restrictions of their budget constraint.The contribution of this study is twofold. First, the paper aims at eliciting preferences for redistribution in Germany with the help of a Discrete Choice Experiment (DCE), based on a represent...
