We investigate the relationship between interstate highways and highway vehicle kilometers traveled (vkt) in US cities. We find that vkt increases proportionately to highways and identify three important sources for this extra vkt: an increase in driving by current residents; an increase in...

Transport infrastructure has represented one of the cornerstones of development and cohesion strategies in the European Union (EU) and elsewhere in the world. However, despite the considerable funds devoted to it, its impact remains controversial. This paper revisits the question of to what...

Evaluating the impact of transport infrastructure meets a major challenge since rail lines are not randomly located. We use the natural experiment offered by the opening and progressive extension of the Regional Express Rail (RER) between 1970 and 2000 in the Paris metropolitan region, and in...

This paper analyzes the political economy of transport-system choice, with the goal of gaining an understanding of the forces involved in this important urban public policy decision. Transport systems pose a continuous trade-off between time and money cost, so that a city can choose a fast...

We study the interplay between transportation infrastructure, knowledge flows, and innovation. Exploiting historical data on planned portions of the interstate highway system, railroads, and exploration routes as sources of exogenous variation, we estimate the effect of U.S. interstate highways...

We estimate the effects of major roads and public transit on the growth of major cities in the US between 1980 and 2000. We find that a 10% increase in a city’s stock of roads causes about a 2% increase in its population and employment and a small decrease in its share of poor households over...

After deregulation in 1980, competitive pressures forced the large U.S. freight railroads to restructure. Much attention has focused on defensive (cost-cutting) restructuring: until 2004 employment was reduced by 60%, and railroads abandoned many of their lines. Less attention has been given to...

Ethnic favoritism is seen as antithetical to development. This paper provides credible quantification of the extent of ethnic favoritism using data on road building in Kenyan districts across the 1963-2011 period. Guided by a model it then examines whether the transition in and out of democracy...

Often, fixed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile networks...

This paper examines the impact of endogenous deficit-balancing subsidies on the cost efficiency of local public bus companies by using alternative frontier cost models for panel data. Thereby, the multidimensional performance estimation incorporates the subsidy variable directly. The empirical...
