Contemporary urban systems in OECD countries are structured around functional regions, which often overcome established city boundaries. Reading space in terms of functional regions allows assessing changes in urban hierarchies and spatial structures, including the polycentricity of urban...

Economists expect positive returns to investments in infrastructure. However a project with higher national returns might have less favourable effects on a regional level than the alternative. Therefore new infrastructure should also be assessed on a regional level, but econom(etr)ic evaluation...

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...

Metropolitan areas --unions of nearby built-up locations within which people travel on a day-to-day basis among places of residence, employment, and consumption--serve as a fundamental unit of economic analysis. But existing delineations of U.S. metro areas--including metropolitan Core-Based...

Economic synergy is essential in functional polycentric metropolitan regions due to their high collaborative potential between area centers and subcenters, which results in greater competition. Our results indicate that, based on the theory of economic geography, economic activities in...

In last decades, the spatial structure of the metropolitan areas has been characterized by an urban dynamics towards a more polynucleated structure, breaking with the paradigm of the monocentric city. The specialized literature has studied these polynucleated urban structures by identifying the...

Nowadays, the urban structure of the metropolitan areas has led to a polynucleated structure, breaking with the paradigm of the monocentric city. The specialized literature has studied this polynucleated structure by identifying the centers that are within of these urban areas. According to this...
