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...

Most studies of the effects of transport infrastructure on the performance of individual firms have focused on marginal expansions of the rail or highway network over time. In this paper, we study the short-run effects of a large discrete shock in the quality of transport infrastructure, viz....

This paper establishes a simple theoretical framework which comprises key forces that shape the structure and interrelation of cities to study the interdependencies between urban evolution and the environment. We focus on the potential of the unfettered market forces to economize on emissions. A...

This paper addresses the timing of a location's historical transition from rural to urban activity. We test whether urbanization occurs sooner in places with higher agricultural potential and comparatively lower transport costs, using worldwide data that divide the earth's surface at half-degree...

This paper quantifies the impacts of transport infrastructure investments on economic activity in Haiti, using satellite night-light luminosity as a proxy measure. Our identification strategy exploits the differential timing of rehabilitation projects across various road segments of the primary...

The recent debates on infrastructure spending have led to renewed interest in the measurement of infrastructure and its effects on growth and well-being. This paper updates estimates of one important type of infrastructure capital—highways and streets. We compare BEA's capital measures with...

We examine the effects of randomly introduced economic inequality on voluntary co- operation and whether this relationship is influenced by the quality of local institutions, as proxied by corruption. We use representative data from a large-scale lab-in-the-field public goods experiment with...
