Das sozioökonomische Wachstum und die raumstrukturellen Veränderungen der letzten ca. 50 Jahre haben Spuren hinterlassen. Dabei zeigt sich ein Spannungsfeld, denn die Bereitstellung von Flächen für urbane Nutzungen geht mit Nutzungskonflikten hinsichtlich der Ressource Boden einher. Im...

The share of the population living in urban centres has vastly increased in recent decades, and is predicted to further expand in the future. In this context, research on the environmental impact of different urban environments, in terms of both the form and built-up structure of cities, is...

In the context of technological progress and economic transition, the urban spatial structure has consistently undergone dynamic evolution. However, the trajectories of polycentric patterns display significant national and regional variations. It is crucial to examine the dynamic evolution of...

A key reason for the existence of cities are the externalities created when people cluster together in close proximity. During Covid, such interactions came with health risks and people found other ways to interact. We document how cities changed during Covid and consider how the persistence of...

We study the adoption of remote work within cities and its effect on city structure and welfare. We develop a dynamic model of a city in which workers can decide to work in the central business district (CBD) or partly at home. Working in the CBD allows them to interact with other commuters,...

Recent work has argued that zoning is responsible for racial segregation, disparities in public goods provision, growing regional inequality, and exploding housing costs in productive areas. However, the slow-moving nature of land regulation's effects suggests a crucial need for historical...

The morphology of today's cities is the result of historic urban developments and ongoing 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...

We study the urban structure of the city of Detroit. Following several decades of decline, the city's current urban structure is clearly not optimal for its size, with a business district immediately surrounded by a ring of largely vacant neighborhoods. We propose a model with residential...

We study how urban land use fragmentation affects the subjective wellbeing of city residents. Therefore, we calculate fragmentation metrics based on the European Urban Atlas for 15,000 households in the German Socio-Economic Panel. Using random and fixed effects specifications, we find that...

Cities are shaped by transportation infrastructure. Older cities were anchored by waterways. Nineteenth century cities followed the path of streetcars and subways. The 20th century city rebuilt itself around the car. The close connection between transportation and urban form is natural, since...

We estimate the effect of urban spatial structure on income segregation in Brazilian cities between 2000 and 2010. Our results show that, first, local density conditions increase income segregation: the effect is higher in monocentric cities and smaller in polycentric ones. Second, the degree of...

In this paper, we study the effects of urban design on pollution and welfare. We build a theoretical model of residential choices with pollution externalities arising from commuting, where the size of the central business district (CBD) and the demand for housing are endogenous. We show that a...

We conduct an empirical analysis to assess the degree of segregation among the different communities in Barcelona taking into account the spatial dependence of the features associated with the neighbor's status. We build an original database by gathering information for the period 1947–2011....

"The Randstad metropolitan region encompassing Amsterdam, The Hague, Rotterdam and Utrecht in the western Netherlands is regarded worldwide as a model of a 'successful' polycentric metropolis. It is widely cited as an example of how a region of interconnected small cities can effectively compete...
