(University of Bonn) Despite long-term profit expectations, many Germans shy away from investing their money in supposedly riskier forms of investment. Why? Together with colleagues from the USA and Switzerland, scientists at the University of Bonn have now developed a model that makes real-life stock buying behavior comprehensible for the first time. The researchers combined socioeconomic, psychological and neuroscientific data in an innovative way. The results will now be presented in the journal "Scientific Reports".
