This thesis examines the influence of cooperative urban land development (CULD) models on
housing supply and price trends in 13 major German cities. Utilising a panel data analysis
spanning the period from 1995 to 2023, linear regressions and difference-in-difference (DiD)
techniques were employed to assess the impact of CULD models on the number of apartment
permits and housing prices. Contrary to initial hypotheses, the introduction of the regulation
did not reduce housing supply, as no significant correlation between the introduction of the
resolution and the decline in building permits could be observed. The study found a significant
correlation between CULD models and rising purchase prices, indicating that regulatory
measures likely contributed to higher costs in market-rate housing. While rental price increases
were less pronounced, purchase prices consistently grew more strongly in cities with
regulations. Overall, the study concludes that while CULD models do not harm housing supply,
they may lead to higher housing prices, especially in the purchase market. The study
recommends that urban planning authorities improve data collection on CULD affected citied
and projects, allowing for more precise monitoring of housing supply, costs, and market
impacts. Standardized nationwide metrics would enable better comparisons across cities and
improve the understanding of how these models influence housing affordability. Further
research should incorporate models with project specific data collection on a representative
level.
