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,...

This paper considers the impact of the introduction of a metro network in the Copenhagen metropolitan area. Using travel surveys from years before and after the opening of the metro network, we observe a significant change in travel times, speeds and mode choice for commutes that can completely...

The following article summarises the first results of a two-part study on consumption patterns in Denmark and leisure travel in Greater Copenhagen in particular. The study aims to map direct (e. g. free time travel) and indirect (e. g. goods and services) energy use related to different types of...

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...

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...

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...
