    Communications on Climate Change and Biodiversity Loss with Local Populations: Exploring Best-practices and Postcolonial Moments in Eight Case Studies from across the Globe

    Climate change and biodiversity loss trigger policies worldwide, many of which target or impact local communities.

    Lights along the Frontier: Convergence of Economic Activity in the Proximity of the Polish-German Border, 1992–2012

    This paper studies regional economic development on the municipality-level in Poland and Germany along the Oder–Neisse border. We use high-quality satellite night-time light intensity data as an innovative and comparable measure to proxy for overall economic activity on both sides of the border consistently over a long period of time (1992–2012). We use descriptive heat maps as well as regression analysis ...

    Forward to the Past: Short-Term Effects of the Rent Freeze in Berlin

    In 2020, Berlin enacted a rigorous rent-control policy: the “Mietendeckel” (rent freeze), aiming to stop rapidly growing rental prices. We evaluate this newly enacted but old-fashionably designed policy by analyzing its immediate supply-side effects. Using a rich pool of rent advertisements reporting asking rents and comprehensive dwelling characteristics, we perform hedonic-style Difference-in-Difference ...

    Inferring Floor Area Ratio Thresholds for the Delineation of City Centers Based on Cognitive Perception

    The morphology of today’s cities is the result of historic urban developments and on-going urban transformation resulting in complex urban spatial structures. While functionally as well as spatially, cities are structured into sub-units such as the city center, business districts, residential areas or industrial and commercial zones, their precise localization in the geographic space is sometimes difficult. ...
