My name is Joschka Wanner and I have very recently finished my PhD in economics at the University of Bayreuth. I hold a Bachelor of Arts in International Economics and Development and a Master of Science in Economics from the University of Bayreuth, as well as a Bachelor of Science in Mathematic and Statistics from the Open University, UK. My PhD thesis is entitled "Gravity in International Trade: Econometric Challenges and Environmental Extensions".

My main research interests are in international and environmental economics, as well as in applied econometrics. So far, most of my work is related to the so-called gravity model in international trade. For example, I have worked on extended structural gravity models that allow an analysis of the effects of carbon tariffs or of unilateral withdrawals from the Paris Agreement and on techniques to estimate non-linear gravity specifications with multiple high-dimensional sets of fixed effects.
