The main scientific contribution of this project is to develop a sociological theory of the reciprocal relationships between social mobility and non-cognitive skills (or socio-emotional skills). This will add to the scientific literature on social inequality. Moreover, it touches on one of the core questions of sociology, namely: How are processes on a structural level linked to individual processes? Additionally, findings based on empirical analyses will also have immediate practical relevance in that they elucidate the interrelatedness of, e.g., success and well-being in modern societies. This postdoctoral project is conducted at Stanford University and the University of Cambridge and is funded by the Swiss National Science Foundation (SNSF).
