Completed Dissertations

Bild: Nora Albu

Dr. Nora Albu

On May 21, 2021, Nora Albu successfully defended her dissertation entitled "Basic Structure of the Economy and Structural Change. An input-output analysis using the example of Germany and France" with success and was thus awarded her doctorate. Her dissertation addresses the question which sectors in an economy can be considered basic in the sense of basic sectors. She examines this using the example of the German and French economies and applying input-output-based methods. The empirical work has high topical relevance, as economic crises such as the global economic and financial crisis of 2008/2009 and the current pandemic-related crisis raise the question of public stabilization programs. 

Nora Albu studied economics and political science at London Metropolitan University (bachelor's degree) and subsequently obtained a master's degree at the London School of Economics and the Free University of Berlin. Since then, she has been working in empirical economic research at the WifOR Institute in Berlin and was an external PhD candidate of the working group from 2019 to 2021.

Dr. Mariia Shkolnykova

From May 2017 to September 2020, Mariia Shkolnykova worked as a research assistant (PhD student) in the department's teaching, third-party funded projects and committee work, and also wrote her dissertation on the subject of "Firm innovation and industry transformation. The case of German Biotechnology". On September 10, 2020 she successfully completed her doctoral colloquium.

The cumulative dissertation deals with the emergence and development of biotechnology in Germany, which has been strongly promoted since the 1980s through targeted technology policy measures and later also contributed to the emergence of the bio-economy. The thesis comprises four empirical papers applying modern methods of quantitative economic research to patent and company data. As part of her doctoral studies, Mariia Shkolnykova visited the Nordic Institute for Studies in Innovation, Research and Education (NIFU) in Oslo for a research stay.

Mariia Shkolnykova continues to work as a research assistant (postdoc) in the research group to continue her innovation economics work and to gain further qualifications in empirical economic research and teaching.

Tobias Wendler

Dr. Tobias Wendler

From October 2016 to January 2020, Tobias Wendler worked as a research assistant on his dissertation on "Green Technologies and their Role for Sustainability", in addition to teaching and third-party funded projects. In March 2020 he successfully completed his doctoral colloquium.

In his cumulative dissertation, he deals with the effects of environmental innovations on the reduction of greenhouse gases and on the conservation of natural resources in the countries of the European Union. He places the four empirical papers in an interdisciplinary context, which is fed by natural, environmental and social science considerations on sustainability. With a focus on green technologies and natural resources, his work makes an important contribution to empirical innovation economics.
