* The Recovery Fund recently proposed by the EU Commission marks a sea-change in European integration. Yet it will not be enough to meet the challenges Europe faces. There has been much public debate about financing, but little about the sort of concrete projects that the EU should be putting...

Following market liberalisation, the vehicle population in China has increased dramatically over the past few decades. This paper examines the causal impact of the opening of a heavily used high speed rail line connecting two megacities in China in 2015, Chengdu and Chongqing, on air pollution....

Urban road infrastructure is crucial in determining air pollution. Yet, little is known about the roles played by road width vs. road length. This paper attempts to fill this gap by estimating the effects of road infrastructure on 10-micron particulate matter (PM10) using city-level data from...

The transportation sector is a major source of air pollution worldwide, yet little is known about the effects of transportation infrastructure on air quality. This paper quantifies the effects of one major type of transportation infrastructure—urban rail transit—on air quality using the...

In densely-populated countries and in particular in large metropolitan areas, the presence of so much human activity causes all sorts of negative externalities, for example traffic noise disturbance. These externalities call for corrective measures by the government. Economists have developed a...

Transport has significant externalities including carbon emissions and air pollution. Public health research has identified additional social gains from active travel, due to health benefits of physical exercise. Per mile, these benefits greatly exceed the external costs from car use. We...
