• Lagging regions and policy

    Involved researchers: Thomas Brenner, Tobias Hertrich, Franziska Pudelko, Sven Wardenburg

    The growing inequality between regions is one of the main economic problems in Germany, the EU and many other spatial entities. Various policy measures, such as the GRW funds, are taken in order to foster economic development in the lagging regions. Our research agenda aims to support policy makers by enlarging the understanding for economic dynamics and innovativeness in lagging regions, by providing indicators for structural weaknesses and classifications of regions, and by examining the effects of policy measures and their dependence on regional circumstances. Part of this research is done within the projekt StRegInno funded by the German Ministry of Education and Research.

  • New technologies and innovation - spatial distribution and policy

    Involved researchers: Thomas Brenner, Tobias Ebert, Franziska Pudelko, Sidonia von Proff, Sonja zu Jeddeloh

    The emergence of new technologies and innovations is not equally distributed in space. Besides studying innovation efficiency, innovation networks and various regional determinants – theoretically based on the concept of Regional Innovation Systems –, the research agenda also focuses on the innovativeness of start-ups and the spatial distribution of some new industries. Currently the focus is on the wind energy industry and the bioeconomy. The latter focus is part of the project BioTOP financed by the German Ministry of Education and Research, which deals with policy options for fostering the bioeconomy.

  • Nexus of climate change, human (im)mobility, and health

    Involved researchers: Thomas Brenner, Ann-Christine Link

    Climate change is considered a risk multiplier not only when it comes to human (im)mobility (migration, displacement, and planned relocation) but also health (physical and mental). The goal of the working group is to disentangle parts of the nexus between climate change, migration and health to not only get a better understanding of the connections between the parts of the nexus but also to support people on the move, people with high health risks as well as people finding themselves in trapped situations. Accordingly, we work on the following research themes:

    1) Impacts of meteorological and air conditions on pneumonia and influenza hospitalizations, considering the influence of various personal characteristics (age, sex, pre-existing diseases, etc.) in Germany
    2) Impacts of climatic and environmental factors on internal migration in Europe and internal and international migration in Germany
    3) The integration of human (im)mobility in the context of climate change into relevant national policies such as NAPs and NDCs, as well as the specific consideration of the climate change, human (im)mobility, and health nexus
    4) A climate resilience and well-being comparison of people in the Global South with and without a migration background (e.g., Ethiopia, India)
    5) Assessing the well-being and integration of Ukrainian refugees in Germany and internally displaced people (IDPs) in Ukraine due to the Russian war in Ukraine

  • Determinants of national growth (especially in developing countries)

    Involved researchers: Thomas Brenner, Masoumeh Ghorbani

    National economic growth still is one of the main aims of governments. The literature provides various theories and empirical studies. The research agenda contains three research aims for the next years: 1) A new growth model is developed that provides two advances to the existing theories: It takes account of the different situation in different countries and their interaction and of the different kinds of innovation and imitation processes (model is in development). This will allow to study the differences between developed and developing countries and to identify the specific factors to trigger growth in the latter. 2) New statistical methods are applied to the analysis of national growth to identify differences in the relevance of factors for different kinds of countries. In addition, the influence of climate change on growth is studied. 3) More specific studies of a number of countries are conducted and planned, especially on Iran, India and China, looking at the growth factors, innovation activities and regional distribution.

  • Regional economic dynamics, universities and clusters

    Involved researchers: Thomas Brenner, Tobias König

    Clustering is a major topic in the research agenda of the working group since more than 10 years. The identification of clusters and policy options to support clusters have been studied extensively. Recent research has focused on the interaction of various economic variable on the regional level and especially on the impact of universities on the regional economy. Actual research projects focus on the lack of qualified labour in clusters and in-depth cluster case studies.

  • Spatial methods

    Involved researchers: Thomas Brenner, Tobias Ebert, Franziska Pudelko, Sven Wardenburg

    The importance of spatial statistics has tremendously increased in recent years, in geography as well as in many other disciplines. This is further triggered by the increasing availability of fine-grid spatial data. The research group contributes to this in two ways. 1) Modern statistical methods, such as spatial vector auto-regressive models, that allow for the detection of causal relationships and the identification of indirect effects are introduced and applied to various fields of research. In addition, this methods are advanced with respect to the consideration of spatial effects. 2) Fine-grid data based on addresses or at least municipalities is used to analyse economic processes. In this context methods to bring point data to the regional level are developed, distance decay functions are estimated and spatial regressions using such data are advanced and applied.
