The position will be based in the working group “Welfare and Policy Design”, head-ed by Prof. Dr. Matthias Kalkuhl at Research Department “Climate Economics and Policy”.
The main, long-term task will be to contribute to our research agenda on tax clubs and jurisdictional reward funds that is described here. Additionally, the person filling the position is expected to assist with short-term, ad-hoc tasks (mainly background research) across the spektrum of German and EU climate-economic policy in the areas relevant to the working group’s research focus.

Key responsibilities:

• solving our existing economic models (analytically and numerically)
• visualizing and explaining the results for academic publications and policy briefs
• refining the models and their empirical calibration
• literature reviews and topic-specific background research in economic publi-cations, public databases and legislative documents

You are a Bachelor or Master student, enrolled at a German university, and ide-ally meet the following requirements:

• studies in the field of economics, mathematics, computer science or related fields
• good understanding of welfare and environmental-economic concepts, e.g., social welfare maximiziation, externalities, Pigouvian taxation
• profound interest in current issues in climate policy in Germany and the EU
• strong programming skills or strong motivation to acquire them
  (more specifically, the skills to leverage tools like Claude Code)

We expect:

• strong motivation to contribute to impact-oriented research, combining aca-demic rigor and focus on policy relevance
• high willingness to work collaboratively in an international and diverse work-ing group
• very good understanding of English (German language skills are an asset)

We offer:

• opportunity to participate in collaborative economic modelling tailored to de-velop, optimize and evaluate new proposals for international mechanisms, drawing on public economics (optimal taxation, tax competition, tax inci-dence, welfare economics), international trade theory, game theory and mechanism desin theory
• supportive work environment in our team
• attractive working space at the EUREF-Campus in Berlin Schöneberg
• flexi-time and mobile working
• subsidized travel card or Deutschland-Ticket Job
