Professional profile

Before joining BSEL, I worked for the non-partisan Berlin Institute for Financial Market Research, of which I was executive director. I was also with the Division on Globalisation and Development Strategies (DGDS) of the United Nations Conference on Trade and Development (Geneva). I have studied economics and political science at the Rheinische Friedrich-Wilhelms-University of Bonn and economics at the Free University of Berlin.

After receiving my diploma in economics (equivalent to a master degree) in Berlin I worked as a lecturer, research fellow and assistant professor for international economics and macroeconomics at the Berlin School of Economics and Law, the University of Applied Science (Berlin) and the Free University of Berlin from which I also hold a doctoral degree. With my colleagues at the Institute for International Political Economy at BSEL I share concerns about the extent and frequency of financial crises as well as about rising global inequality and (financial, social and economic) exclusion of individuals, communities and even complete countries.

Whom I support

  • Though according to German law tenured professors as civil servants are not allowed to strike, they are nevertheless employees. Hence, I am member of a trade union.
  • Since 2015 I am an appointed Lay Judge at the Berlin Social Court. I am assigned to chambers dealing with disputes of the statutory social insurance system, in particularly the public care, health and pension insurances.
  • Empowerment of civil society also requires the means and opportunities to speak up and give independent voices leverage. Hence, I am happy to subscribe and donate to both Afrika Süd (a journal on Southern African issues) and IZ3W (Information Centre Third World).

On my behalf

Professional and personal integrity are of importance to me. Regrettably, my discipline is not at the forefront of promoting professional economic ethics. Or as Georgio DeMartino (2012, p.2), one of the editors of The Oxford Handbook of Professional Economic Ethics, stated “Today, economics is certainly among the most important of professions in terms of its impact on the world. But in all that time the profession has never attended to the ethical burdens associated with influence over others.”

I am a member of inter alia the German Keynes Society,  American Economic Association, the Migration Research Hub (by IMISCOE) and the International Network for Economic Research (INFER), but also the German Economic Association (Verein für Socialpolitik), which has accepted a code of ethics only in July 2012. Nevertheless, there are huge blind spots not being dealt with until today. This applies to many countries, but in particularly to Germany whose institutional setting to enforce (individual and structural) compliance in academia has to be assessed as weak. We do not have resilient self-control mechanisms or any form of whistle blower culture.

To the blind spots belong the following three issues. Although it is meanwhile a kind of international standard that researchers display the amount of research funding which they receive from external entities, the Code of Ethics of the German Economic Association only requires naming the external sources, but not the detailed amounts nor the regularity of that kind of finance. Second, by current law, German civil-servant professors are entitled to devote up to 20 per cent of their working time to so-called extra-mural activities. The only requirement is that they notify these activities in advance to the HR of their university and make an official request for permission; approval is a pure formality as long as the 20 per cent cap is not overdrawn. This leaves professors and contracting entities with an almost unlimited discretionary scope: they only need to fiddle with the daily lump sum to comply with this ‘requirement’. Professors are not automatically obliged to disclose their earnings derived from these extra-mural activities. Everyone who is familiar with the salary levels of German civil servants would not be surprised if many of these extra-mural activities generate revenues as much or even, sometimes, more than the official salary - and with that substantial conflicts of interest may rise. Third, professors are frequently offered discounts on private goods and services, for instance by publishing houses, for inspection copies of text books for their courses. But also newspapers and non-academic journals, software and hardware companies and even private (health) insurances offer discounts. On the other side there is a strong rise in academic journals requiring researchers to pay for the referee process of their submitted papers. While the former should constitute the acceptance of amenities for private purpose, which - according to the letters of the law - is strictly forbidden for civil servants, the latter might be caused by a cut-down of library budgets during the last 25 years which had been a steady source of finance in former times. But none of the two trends and the potential conflict of interests arising from them are dealt with in the Code of Ethics of the German Economic Association.

Projects

Moving Minds and Money is a research network formed in 2022, driven by passionate students, professors, researchers, and professionals. The focus of the network is on the movement of monetary values and idea exchange within and between communities. Current research spans FinTech for underserved populations, empowering rural areas through digital devices, and exploring practical applications for digital payment methods and currencies.


OurVillage

The OurVillage Cameroon project, launched in 2020 by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), addresses seasonal income fluctuations in rural communities in Cameroon. During the dry season, reduced agricultural production and ongoing demand often lead to retail demand shifting from villages to larger cities at the expense of local economies.

To tackle this, the project introduced an unbacked digital community currency that can only be used within each village. Accessible via mobile phones, this community currency helps to keep money circulating locally and strengthen economic resilience. The initiative has been implemented in three communities Bameka, Batoufam, and Fondjomekwet.

A research team from the “Moving Minds and Money” network, led by Martina Metzger, Jennifer Pédussel Wu, and Arafet Farroukh, evaluates the project through qualitative analysis, user surveys, and field engagement. Their work results in reports, recommendations, and a monitoring system that tracks the project’s effectiveness.

Findings are shared with GIZ, other stakeholders and other interested parties. 


Summer school (2022) and DiGiCamp (2023, 2024) in cooperation with Faculté des Sciences Economiques et de Gestion de Université Tunis El Manár

The Digicamps are a joint initiative of BSEL and FSEGT Tunis revolving around critical issues concerning the development and rapidly progressing digitalisation of the global financial industry. The programmes encourage student involvement and seek their input in developing novel solutions and approaches to pressing questions within the field.

 

In co-operation with Southwestern University of Finance and Economics (SWUFE Chengdu/China) and Deutsche Bundesbank Regional Office Berlin and Brandenburg as well as the People’s Bank of China, Shanghai Head Office BSEL holds regularly monetary policy workshops. Actually, BSEL has a long-standing co-operation with SWUFE, going back as far as 1986; meanwhile it covers joint research projects and the monetary-policy-workshop series. The workshops seek to bring together representatives of academia with central bankers and policy makers for a dialogue on current issues of domestic monetary policy and international monetary architecture. They are alternately organised by SWUFE and BSEL. 

Co-operation partners: Deutsche Bundesbank Regional Office Berlin and Brandenburg, SWUFE Chengdu.

Funding: Deutsche Bundesbank, SWUFE, own resources.

The Master´s programme in Tax Policy and Tax Administration (MA Tax) is a 15-month executive MA programme with a strong African and international focus. It is designed for experienced tax officials and policy-makers in Sub-Saharan Africa and the wider Global South. A functioning public-finance system represents the backbone of a capable state that provides public goods and services according to citizens’ basic needs and demands in a transparent and accountable manner. Thus it is suggested, then, that governments are committed to providing systems that ensure the effective, simple and fair collection of taxes in order to finance inclusive and sustainable development. The MA Tax programme intends to contribute to these goals.

The third cohort of the MA Tax programme, in co-operation with ATAF and GIZ, has been put on hold until further notice. Although Berlin School of Economics and Law intended to open applications in the Fall of 2018, GIZ informed us that there would be a call coming for a renewed co-operation between ATAF, GIZ, and an eligible university to jointly offer a MA Degree in taxation.  Given this new situation, Berlin School of Economics and Law decided to postpone the opening of the application for the MA Tax programme. Any change to the Berlin School of Economics and Law position will be announced here. If you would like to be informed about future changes in the MA Tax programme by the Berlin School of Economics and Law, please send us an e-mail.

Co-operation partners: African Tax Administration Forum,  Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), International Centre for Tax and Development (ICTD Brighton/UK), University of Witwatersrand (Johannesburg/South Africa).

Funding: European Union, German Federal Ministry for Economic Co-operation and Development, Deutsche Gesellschaft für Internationale Zusammenarbeit.

This co-operation, launched only in 2015, operated with a limited exchange of students, lecturers and professors. We intended to deepen the co-operation with workshops on a topic of mutual interest and relevance for promoting sustainable development, for instance on FinTechs. Accordingly, we were happy to host the international workshop ‘FinTechs, Remittances and Development’ in Berlin, 21-22 June 2018. While in Africa still a relevant share of population is cut-off from traditional financial services, the access to digital services and the coverage with mobile phones is in the overwhelming majority of African countries comprehensive.

In some African countries, we even find several pioneers of digital financial services. The most famous country pioneering digital financial services is Kenya, in which the traditional rift between telecommunication and financial services has been resolved. Several other countries are also displaying innovative entrepreneurial initiatives worthwhile to explore deeply the triggering and hampering factors in diverse macroeconomic and regulative environments.
