Andreas holds a master's degree in economics from the University of Oslo. During his studies, he specialized in statistics, mathematics, applied econometrics, environmental and resource economics and dynamic modeling, with very good results. In his master's thesis, Andreas investigated the welfare effects of technology transfer between rich and poor countries in a global economic model that captures the interaction between the climate, a number of different energy carriers and three economic sectors for each country. A large part of the work devoted to the systematic collection of macroeconomic data, price data and consumption data for the various sectors of the economy, as well as calibrating the theoretical model to real economic variables.

Next to his studies, he was seminar leader for a master's course in resource economics and worked as a research assistant on two different research projects. Previously, Andreas worked as a teacher, and in addition to his quantitative background from his economics education, he has experience with the use of qualitative research methods, such as semi-structured interviews.
