This project examines empirically in how far fairness preferences have an influence on giving behaviour of individuals, especially on the purpose donations go to. To this end we conduct an experiment where participants may divide a fixed amount of money up into private consumption and donations to selected charities. Fairness preferences are collected by means of modified dictator and ultimatum games. Furthermore, we collect important socioeconomic variables which have been shown to influence giving behaviour with a questionnaire. In an econometric analysis the impact of inequity aversion and further variables on the decisions whether to give at all and how much to give is measured. The results contribute to a better understanding of giving behaviour in Germany and of the impact of fairness preferences on the private provision of public goods.
