New study on socio-economic polarization in Europe

Posted July 9 2019

We just completed a research project for the Friedrich-Ebert Foundation, in which we study polarization patterns in Europe, and provide some suggestions for adequate policy responses. The study alongside additional material can be found here. An English translation will be available soon.

New homepage

Posted March 19 2019

Due to problems with the links and content management I needed to update my homepage. I wasn't able to migrate all material, so some links are still not working, but I will fix them during the next weeks.  

New working papers

Posted February 22 2019

I have produced a number of new working papers on which any feedback is highly welcome. Two of the papers are empirical: In the first one, The heterogeneous relationship between income and inequality: a panel co-integration approach, we quantify the long-term relationship between inequality and GDP per capita using panel co-integration techniques. We provide some new empirical insights, the most important of which are: first, the relationship depends on whether market-based or disposable-income-based measures for inequality are used, and, second, the relationship is not uniform around the world: some countries experience a positive, others a negative relationship. This delineates a number of interesting avenues for future research. The second short empirical paper, Export performance, price comeptitiveness and technology: Revisiting the Kaldor paradox, asks whether the Kaldor paradox, according to which higher relative labor costs and less favorable terms of trade are associated with higher export shares, is still observable and how it can be rationalized.

The other two working papers are theoretical: in Defining institutions - A review and a synthesis we develop a taxonomy of definitions that distinguishes between model-based and non-model-based definitions. Against this backdrop we review existing definitions of economic institutions and identify a shared idea of most definitions, according to which institutions are "codifiable systems of social structures(in particular norms and rules) that lead to inclinations for people to act in specific ways". The second theoretical paper, Unrealistic models and how to identify them: on accounts of model realisticness, is concerned with the question: How can we classify a model as being realistic or unrealistic? This seemingly straightforward question is philosophically interesting since it touches on a number of contested areas, such as the concept of representation, the nature of model-world comparisons and the ontology of models.

Herbert Simon Best-Paper Award

Posted September 12 2018

I am happy to receive the Herbert Simon Award for the best paper by a young scholar, awarded by the European Association for Evolutionary Political Economy (EAEPE), for my working paper Pluralism in Economics: Its critiques and their lessons, which I have co-authored with Birte Strunk and for which any feedback is still very welcome. Here is also a nice note in the Heterodox Economics newsletter, along with additional information on the EAEPE conference in Nice. I really enjoyed the conference and will certainly attent the conference next year in Warsaw as well.

New working paper on measures of economic openness

Posted August 18 2018

When working on topics related to globalization and economic openness, one is quickly confronted with a considerable number of different measures for economic openness. Thus, we wrote a review entitled Measuring Economic Openness: A review of existing measures and empirical practices in which we present, discuss and compare various measures for openness. We provide for a taxonomy of such measures and show with a practical example that the choice of the measure is very important for the outcome of any quantitative analysis of economic openness. Any feedback is very welcome!

Launch of a video-based introduction ABM in Python

Posted July 19 2018

I have launched this video-based introduction to ABM in Python. It consists of scripts, and videos explaining hands-on the content of the scripts. The course aims to teach people without previous experience in programming both the basics in the programming language Python as well as the basics of agent-based modelling using Python. For now, the videos are only available in German, but the scripts are also available in English (see the English course homepage). For any video block there is a feedback form, and I greatly value your feedback on this course. This feedback will not only help me to improve the course in the future, but also build a good English version of the course.

New presentation on theory development in economics and lessons for ABM scholars

Posted July 9 2018

I was invited to give talk during this great symposium on theory development with agent-based models. My presentation is about how economists construct theory, and what lessons one can learn from this process - in the positive as well as in the negative sense. The slides are available here (some pictures were removed to avoid potential copyright issues). Who is interested in these kind of questions might also have a look at my new paper on model validation and verification in JASSS. As always, any feedback is highly appreciated.
