My name is Claudius Gräbner and I am an economist working as a Junior Professor (W1 TT) at the Europa University Flensburg (Germany) and as a research associate at the Institute of Comprehensive Analysis of the Economy (ICAE) of the Johannes Kepler University Linz (Austria). I am also a research fellow of the Institute for future-fit economies (ZOE).
My research is mainly concerned with the socio-economic effects of globalization, the determinants for international competitiveness, economic complexity, institutions and socio-economic development. Besides, I am also interested in economic methodology, in particular how economic models can be helpful in understanding real economic systems.
On this homepage I provide some information and material about the research projects I am responsible for, my teaching and lecturing activites, my research, and myself.

Me and my colleagues developed a model of a monetary union that is characterized by strong differences in terms of the competitiveness of its members. In our most recent paper, which has been published in the journal Structural Change and Economic Dynamics, we explore the implications for economic dynamics, as well as possible policy measures to stabilizes such a monetary union. The paper is available open access here.
For all who want to work on a dissertation project in the the context of pluralist economics: as of October 1 there will be a 50% TV-L13 position to be filled at the Europa-University Flensburg. The deadline to apply is July 10, and you can find more information here.
I was guest on the (German-speaking) podcast “In der Wirtschaft”. In about 70 minutes we spoke about the pros and cons of economic modelling, especially agent-based models, but also the need for pluralism in economics and current debates about degrowth. You can listen to the episode here.
At the invitation of Rethinking Economics Tübingen, I gave the opening speech for the public lecture series “Economics crises and the crisis of economics”. The title of the talk was "Liegt die Wahrheit irgendwo dazwischen? Eine plurale Perspektive auf globale Ungleichheit” and the slides are available here.
On December 16 I gave a lecture on how a pluralist approach can be helpful in diagnosing and addressing socio-ecological challenges. Among other topics, the lecture covered the controversies on the main determinants of global inequality and the question of whether economic growth is a rather a reason, or a solution for the pressing societal challenges of the 21st century. The slides are available here.
On November 17 I gave a lecture in German on the central pillars of the research program of complexity economics, and how it differs from (and can be an alternative or a complement to) the equilibrium-based approach that is very representative for the economic mainstream today. I was invited by the group EconoMix and the slides of the talk are available here.
On October 19 I gave a 30 minutes lecture in German on the topic "What is pluralist economics/Was ist Plurale Ökonomik?". I was invited by the group Rethinking Economics Kiel, who organize the public lecture series "Wirtschaft für Alle! - Plurale Perspektiven für eine zukunftsfähige Ökonomie". The slides of the talk are available here. There is also a recording of the talk that is available via Youtube.
As of October 1 I am working at the Europa University of Flensburg in Germany. I am very happy to join the International Institute of Management and Economic Education (IIM) as a Junior Professor for Pluralist Economics. I will also work closely with the Norbert Elias Center for Transformation Design & Research (NEC) and I am very much looking forward to this new opportunity. I will post some explanations about what I belief a Professor for Pluralist Economics should do in the upcoming weeks since I expect many people not to be too familiar with the concept. For now, however, I just say that I am very happy to join the Europa University in Flensburg, but also feel sad for leaving the great Institute for Socioeconomics at the University of Duisburg-Essen, which was a great place for me to work.
Our paper Capability accumulation and product innovation: an agent-based perspective has now been published in the Journal of Evolutionary Economics. In this paper we study the implications of different degrees of product relatedness on innovation dynamics. More precisely, a population of firms invests into various measures of capability accumulation (as identified in this paper) and thereby learn to produce new - and potentially more complex - products that can then be sold on a market with exogeneous demand. The models shows that different structures of relatedness, which we formalize via artificial product spaces, have imporant implications on the overall dynamics, just as the distribution of complexity values within the product space and the structure of the product space as such. This is highly relevant for future modeling exercises since models often implicitly assume a complete product space, where each innovation can happen at any moment, or randomly distributed complexity values. Our model shows, however, that these implicit assumptions are very specific special cases and that any deviation from these special cases comes with important implications for the overall dynamics.
