Describe the research design and empirical strategy that you would employ to study a (causal) relationship of your choice. The relationship has to involve facets of personality that we have discussed in the course (e.g. personality traits, economic preference(s) such as risk preferences, time preferences, or social preferences, or cognitive skills). The relationship can, for example, be a relationship between preferences and an outcome, but it could also concern topics like determinants, transmission or malleability of facets of personality.
