Private investors often need the assistance of financial advisors. The aim of this project is to improve the advice process such that the satisfaction of investors increases based on a better alignment of investors’ preferences and investment decisions. To achieve this aim, several online-experiments are conducted to develop measurement and explanation tools for risk- and sustainability preferences. In particular, investors with little experiences and low financial literacy are in the focus of this project. Finally, it is also an aim to test the developed information-tools in a field-experiment in collaboration with banks.
