The Unit Empirical Economic Research conducts empirical and especially econometric studies in the fields of environmental, energy, climate, and sustainable economics. Our studies are mainly based on data from representative national and international household surveys, which are used to examine, for example, voluntary climate mitigation and adaptation measures, preferences for regionally produced green electricity, the perception of distribution effects due to energy policy measures, preferences for sustainable consumption, and preferences for sustainable and responsible investments. In addition, we use firm-level data, for example, for the analysis of the relationship between sustainability performance and financial performance.
