Keynote lecture on measures of economic complexity and development

Posted June 28 2018

I was invited to give a half-day introduction to measures of economic complexity and how they can be used in the context of development studies. I introduce three measures: the measure of invention complicatedness of Lee Fleming and Olav Sorensen, the measure of structural complexity by Tom Broekel, and the economic complexity index of Cesar Hidalgo and Ricardo Hausmann. The latter is discussed in more detail.

Invited talk on ABM and theory development

Posted July 9 2018

I am happy I was invited to contribute to the excellent symposium on Theory Development Through Agent-Based Modeling, which was concerned with the question of how ABM can be used for theory development.

My presentation was concerned with the lessons we can draw from economics. My main argument is that because economics has a rather narrow core approach, characterized by rational choice modelling (the so called optimization-cum-equilibrium approach), theory development works smoothly: there are few problems of communication and theoretical and empirical work is well aligned. Current practice of the ABM community is lacking exactly this. At the same time, the rather narrow approach of economics leads to some blind spots. Thus, there are positive lessons to be learned from economics, but also some potential difficulties, which can, however, be avoided by developing adequate institutional guidelines.

New presentation on path dependent development in Europe

Posted April 15 2018

I recently gave an invited presentation at the conference Renewal of the European Economic Integration Concept, held at the University of Szeged, Hungary.

The presentation is mainly based on the paper Structural change in times of increasing openness: assessing path dependency in European economic integration .

Presentation on unrealistic models at the TINT workshop in Helsinki

Posted October 25 2017

I was honored to give a presentation at the workshop What to Make of Highly Unrealistic Models? at the Academy of Finland Centre of Excellence in the Philosophy of Social Sciences. My presentation was about the various ways models can be termed ‘unrealistic’ and when and how they can still be useful.

Public lecture on Complexity Economics in Bochum, Germany

Posted June 13 2017

Yesterday I was invited to give a public lecture on Complexity Economics at the Ruhr University in Bochum. The local student group for Pluralism in economics organizes this great even, and I feel proud to be among the speakers. You can find more information on the group and their events on their facebook page. The talk was in German and you can get the material below. Feedback, as always, very welcome!

19/05/2017: Verification and validation of agent-based models: Epistemological importance and theoretical challenges

This presentation was a keynote at the workshop “Agent-based modelling in economics – From toy model to verified tool of analysis” organized by Prof. Sylvie Geisendorf . I discuss ways to verify and validate ABM, and interpret these approaches from an epistemological perspective.

12/12/2016: The complexity challenge: Systemist thinking, computational modeling, and pluralism in economics

I was happy to receive the WIWA Young Scholar Award for Pluralism in Economics. In this context I gave at talk during the public lecture series of the student group for Pluralism in Economics at the University Witten/Herdecke on what I call the complexity challenge: what does it mean for social systems to be complex? What are the methodological implications? I try to answer these questions and show why the necessity for pluralism in economics follows from the complexity of economic systems.

The talk was in English. As usual, feedback is highly welcome.

21/11/2016: An introduction to institutional economics

The Critical Economists, a highly active student group in Berlin, invited me again to their public lecture series on Schools of thought and controversies in economics. It’s an amazing project that allows students to broaden their horizon and explore different approaches to economic theory as part of their Bachelor or Master at one of the big Universities in Berlin (Free University, Humboldt University, Technical University). Thus, I am happy I could contribute a lecture on institutionalism and an exercise session on agent-based modeling and complexity.

I tried to introduce both evolutionary-institutionalist and neo-institutionalist theory and make people aware of the different definitions of institutions in the literature.

The talk was in German. As usual, feedback is highly welcome.

20/05/2016: Computations, Mechanisms, and Socio-Ecological Systems. A meta-theoretical appraisal of ABM

This presentation was a keynote at the workshop “Agent-based modelling in Ecological Economics - A useful tool or just a fancy gadget?” organized by Prof. Sylvie Geisendorf . It provides a meta-theoretical assessment of agent-based modeling, with a particular focus on socio-ecological systems (i.e. systems in which both social and ecological mechanisms are or interest).

10/05/2016: Networks and complexity in the economy (in German)

This lecture introduces the concept of systemism and illustrates the role that networks play in the economy. I introduce basic concepts of graph theory and illustrate that networks always play an (at least implicit) role in economic theorizing.

Ich führe kurz in das Konzept des Systemismus ein und beschreibe dann die Rolle, die Netzwerke in unserer Ökonomie spielen. Danach führe ich grundsätzliche Konzepte der Graphentheorie ein und zeige, dass Netzwerke immer (manchman jedoch nur eine implizite) Rolle in der ökonomischen Theorie spielen.

09/02/2016: Introduction to Complexity economics (in German)

This is a lecture at the Free University Berlin. It’s an introductory-level introduction to complexity economics that focuses on intuition and examples, rather than mathematical concepts.

Diese Präsentation habe ich im Rahmen einer Vorlesungsreihe an der Freien Universität in Berlin gehalten. Sie versteht sich als Einstiegsvorlesung, die mehr Wert auf Intuition und Beispiele, als auf mathematische Konzepte legt.

10/08/2015: Workshop: An Introduction to Complexity Economics (in German)

This presentation is part of a short course taught together with my colleque Dr. Torsten Heinrich. In the first presentation I give a short introduction to the concept of complexity and its historical origins. In the second presentation I introduce basic concepts of network theory and some applied models.

Diese Präsentation ist Teil eines Kurses, den ich gemeinsam mit meinem Kollegen Dr. Torsten Heinrich gehalten habe. Die erste Präsentation stellt eine kurze Einführung in die Komplexitaetsökonomik und ihre historischen Wurzeln dar. Die zweite Präsentation führt einige grundsätzliche Konzepte der Netzwerktheorie und einige angewandte Modelle ein.

15/01/2013: Pluralism, Complexity, and Microeconomics

This is a very quick introduction to the concept of complexity and an illustration of how pluralistic teaching in microeconomics is possible. Using the textbook “Microeconomics of Complex Economies” as an example I present a way of teaching micro that gives room for different schools of thought and starts with game theory instead the the neoclassical market model.

Nach einer kurzen Einführung des Konzepts der Komplexität zeige ich anhand des Lehrbuchs “Microeconomics of Complex Economies” wie eine pluralistische Lehre in der Mikroökonomik möglich ist. Der vorgeschlagene Ansatz berücksichtigt verschiedene Denkschulen und startet mit der Spieltheorie, und nicht dem neoklassischen Wettbewerbsmodell.
