Critical Mathematical Economics

Thanks a lot for your interest in my homepage on Critical Mathematical Economics (CME). It stands for combining advanced tools from modern mathematics with a critical view towards economics, especially towards the "free market ideology", which claims that unregulated markets benefit everyone and achieve a "social optiumum" (see e.g. The Financial Crisis and the Systemic Failure of Academic Economics, Dahlem Report 2008).

A different term for such a project could be Mathematics for New Economic Thinking, this is the title of a workshop organized by Matheus Grasselli at the Fields Institute in Toronto - he has also given a video-interview How Advanced Mathematics Can Support New Economic Thinking. I did a Post-Doc with him in Canada 2014-2015 at McMaster University and at the Fields Institute, where I also co-organized a workshop on Complexity Economics and one on Inequality.

Currently, I work as "Advisor for Data Engineering, Data Science and Machine Learning" at the Zukunft – Umwelt – Gesellschaft (ZUG) gGmbH. My project there is called "AI Commons Lab" (KI-Ideenwerkstatt in German), and deals with applications of artificial intelligence for the common good, with a focus on protecting the environement. Recently, I have organized two "Lab Talks" with topics related to Circular Economy (more info here and here, in German).

Before, I have worked at the department for political strategy and fundamental policy questions at the federal office of the party DIE LINKE. I am also an Associated Member of the IPE Berlin and of the research group on Mathematics of Machine Learning at FU Berlin, where I am part of the project Machine Learning, Critical Mathematical Economics and Progressive Policy.

For more information on my general research interests, please have a look at the homepage of my former working group, the Nonlinear Dynamics Group at Free University Berlin. But please note that I am not using the email address provided there anymore, but johannes.buchner at z-u-g.org (replace the "at" by @).

Don't hesitate to contact me in case you have any questions/suggestions concerning the material collected below. I would also be very happy if you have ideas for potential common research projects in the direction of CME, as it is a formidable task to build a coherent and appealing alternative to the mainstream currently dominating economics.

Own Research CME

Here are the slides to a talk describing my research projects that I gave at the seminar of the Financial Mathematics Group at McMaster University
A short version of the Research Statement I prepared for a Post-Doc-Application
(in fact CME is a term I coined for this application - to my knowledge, this term was not used elsewhere before, at least google did not find anything with precisely this title in March 2013)
A paper on my earlier research in cosmology has the title Global Dynamics, Blow-Up, and Bianchi Cosmology. In case you are interested, please find more on my research in Non-Linear Dynamics and Artificial Intelligence in the section below.
