This paper aims at investigating the role of different types of proximity on the technological activity of a region within the context of a knowledge production function where R&D expenditure and human capital are the main internal inputs. We intend to assess if, and how much, the creation of...

This paper contributes to the understanding of the long-run consequences of Roman rule on economic development. In ancient times, the area of contemporary Germany was divided into a Roman and non-Roman part. The study uses this division to test whether the formerly Roman part of Germany show a...

This paper uses a general equilibrium trade framework to estimate the contribution of transport infrastructure to regional development. I apply the analysis to India, a country with a notoriously weak and congested transportation infrastructure. I first analyze the development effects of a...

The commonly-used satellite images of nighttime lights fail to capture the true brightness of most cities. We show that night lights are a reliable proxy for economic activity at the city level, provided they are first corrected for top-coding. We present a stylized model of urban luminosity and...

We study the impact of international long-distance flights on the global spatial allocation of economic activity. To identify causal effects, we exploit variation due to regulatory and technological constraints which give rise to a discontinuity in connectedness between cities at a distance of...

This paper revisits the hypothesis that landlocked regions are systematically poorer than regions with ocean access, using panel data for 1,527 subnational regions in 83 nations from 1950-2014. This data structure allows us to exploit within-country-time variation only (e.g., regional variation...
