November 2026: Presentation of Vipul Chawla at the Homecoming of the Göttingen School of Development Economics
Group member Vipul Chawla presented his research at the Homecoming of the Göttingen School of Development Economics. The presentation was a joint work with Prof. Kopp entitled "A Room of One’s Own? A Panel Data Analysis of Income Inequality and Living Space in Post-Communist and Non-Post-Communist Countries in Europe.”
This study explores the relationship between income inequality and living space in Europe, and whether this association differs between post-communist and non-post-communist countries. The results suggest a significant positive but non-linear relationship between income inequality and living space, which may be explained by competing channels in play: conspicuous consumption at the top and housing crowding at the bottom of the income distribution.
November 2026: Presentation by Prof. Julia Höhler at the Research Seminar
On November 10, 2026, the Department of Agricultural Policy and Market Research invited Prof. Julia Höhler from Wageningen University and Research.
She presented her work entitled "Organising the Bioeconomy: Ownership, Contracts and Cooperation.” Drawing on experimental evidence from farmers and foresters, she discussed how non-binding agreements affect contributions to public goods. The findings offered insights into the design of institutional arrangements that support cooperation and help align private incentives with broader societal objectives in agriculture and forestry.

October 2026: Research Seminar series opens for the winter term 2026/27 with a presentation by Prof. Vivian Wei Huan
On October 27, 2026, the Department of Agricultural Policy and Market Research kicked off our weekly Research Seminar for the Winter Semester 2026/27!
We welcomed Prof. Vivian Wei Huang from the Swedish University of Agricultural Sciences (SLU), Uppsala, who presented her work entitled "Are Environmental Efficiencies of Swedish Agriculture More Transient or More Persistent? Heterogeneity and Determinants.” The study estimates Swedish agriculture's environmental efficiency over 15 years using the Generalised True Random Effects approach, and finds that targeted policies promoting energy-efficient technologies, farm-size optimisation, and refined subsidy structures could improve long-term environmental performance.
Thank you, Vivian, for your valuable insights and presentation!

September 2026: GreenPaths Horizon final meeting
Our final GreenPaths meeting at the Universidad de Cantabria in Santander brought colleagues together to share findings, reflect on three years of collaboration, and consider what comes next for just green transitions.
Daniel Chavez and Donna Andrews delivered thought-provoking keynotes, connecting European transitions with wider global questions on a socially just and ecologically sustainable transition and highlighting the importance of solidarity across borders.
A memorable contribution came from our colleague Aimen Abbas, who reflected on her experience as a junior scholar from Pakistan in GreenPaths. The talk highlighted how supportive collaboration, openness to different perspectives, and space to learn can help early-career researchers grow. Her reflections on finding a sense of community within the project gave our final meeting a particularly meaningful closing note.
Thank you to all our colleagues and partners for the knowledge, care, and commitment they brought to GreenPaths. A special thank you to Judith Clifton, Daniel Díaz-Fuentes, Ana Lara Gómez Peña, and Marcos Fernández Gutiérrez for hosting us in Santander.
As the project draws to a close, we take forward both what we have learned and the relationships built along the way.

September 2026: Braunschweig, GeWiSoLa Annual Conference
Prof. Kopp participated at the annual meeting of the German Association of Agricultural Economists (GeWiSoLa), focusing on the theme "Agriculture and rural areas: challenges in a local, regional and global context", at which there was also a reunion with colleagues from Göttingen.

September 2026: ELU - S Conference in Lisbon
Prof. Thomas Kopp participated in the panel discussion “Toward ‘Long-Term Competitiveness’ in the EU?” at the Annual ELU-S Conference in Lisbon on September 3, 2026. In his contribution, entitled “Beyond Competitiveness as Usual: Toward a Sustainable European Competitiveness Strategy,” he discussed the limitations of an efficiency-focused approach to European competitiveness and argued for a broader understanding of long-term competitiveness.


The contribution highlighted the interdependence of economic dynamism, political functioning, and environmental integrity, arguing that none of these dimensions can be traded off against the others without ultimately compromising Europe's long-term competitiveness. The panel brought together different perspectives on how environmental, social, political, technological, and economic factors should inform the EU's future competitiveness strategy.
July 2026: Participation of several group members at ESEE Conference in Ghent
Several members of our group attended the 16th Conference of the European Society for Ecological Economics (ESEE) from June 30th until July 3rd in Ghent, Belgium. Four group members as well as Professor Kopp presented their current work and enjoyed the discussions with ecological economists from across Europe.


Syeda Aimen Abbas presented her paper titled “Greener at Home, Dirtier Abroad? Environmental Policy Stringency and Emissions Embodied in EU Imports.” This work explores how stricter EU environmental policies can be linked to increasing emissions embodied in imports.

Marcel Böhl, in a joint work with Steffen Lange titled "Rising Prices, Rising Populism: Inflation and Far-Right Populists' Electoral Gains in Western Europe,” analyses a monthly panel dataset of 19 countries over 25 years. This study concludes that inflation tends to increase far-right support in Western European countries.

Markus Nabernegg discussed a joint paper with Luca Salvatici titled "Where is the EKC turning point? A meta-study of in-sample vs. out-of-sample turning points for production- and consumption-based carbon indicators.” This paper reviews studies that utilise the Environmental Kuznets Curve (EKC) to classify them as no EKC, in-range EKC, or out-of-range EKC.

Vipul Chawla presented a paper titled "A Room of One’s Own? A Panel Data Analysis of Income Inequality and Living Space in Post-Communist and Non-Post-Communist Countries in Europe." This study explores the relationship between income inequality and living space in Europe, and whether this association differs between post-communist and non-post-communist countries.

Prof. Thomas Kopp discussed a collaborative research with Severin Caspari and Niklas Heiland titled "Reducing Emotional Distress in Academic Work Environments through Experimental Organizational Development.” This work reveals that a two-hour annual workshop appears to meaningfully strengthen leadership practices and improve the working conditions of junior researchers at universities.

June 2026: New publication in Ecological Economics
Syeda Aimen Abbas and Thomas Kopp recently published the paper "The Distributional Impact of Environmental Policy Stringency in Europe" in Ecological Economics.
The study examines the relationship between environmental policy stringency and income inequality across 26 European countries over the period 1990–2022. Using the OECD Climate Actions and Policies Measurement Framework (CAPMF) and three measures of income inequality, the findings suggest that more stringent environmental policies are associated with higher pre-tax and post-tax income inequality, while the effects on disposable income inequality are not statistically significant. The results highlight the important role of redistributive policies, particularly cash transfers and social spending, in supporting a socially equitable green transition.

June 2026: Presentation of Prof. Kopp at the Italian Association of Agricultural and Applied Economics Conference in Rome
On 11 June, Prof. Kopp presented his joint work with Ashok K. Mishra (Arizona State University) and Alwin Dsouza (New Mexico State University) entitled "Reducing Negative Effects of Risk Aversion on Farming Outcomes: Evidence for Systematic External Selection into Profitable Contracts” at the 15th Italian Association of Agricultural and Applied Economics Conference in Rome.
This study examines the interplay between risk aversion and contract farming in developing and emerging economies, focusing on 660 representative okra farmers in Karnataka, India. Utilising an instrumental variables approach, the empirical analysis confirms that risk-averse farmers are over-proportionately selected into production contracts, which are 46.3% more profitable than marketing contracts. The systemic selection benefits vulnerable, risk-averse farmers by grantingthem privileged access to the most advantageous contract farming arrangements.
The results of the study, relevant for the development discourse, emphasise the benefits of production contracting for poverty reduction, while highlighting the monopsonistic tendencies of contracting firms in controlling the selection of farmers.
