We provide empirical evidence of the dynamics of city size distribution for the whole of the twentieth century in U.S. cities and metropolitan areas. We focus our analysis on the new cities that were created during the period of analysis. The main contribution of this paper, therefore, is the...

This paper proposes a novel methodology for delineating urban areas based on a machine learning algorithm that groups buildings within portions of space of sufficient density. To do so, we use the precise geolocation of all 12 million buildings in Spain. We exploit building heights to create a...

This study tackles the description of the size distribution of urban employment centers or, in other words, the size of areas within cities with significantly high density of workers. Certainly, there exists a branch of urban economics that has paid substantial attention to urban employment...

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...
