Driving restrictions are popular interventions in rapidly urbanizing developing countries. Their relatively inexpensive implementation appeals to the pressing need to reduce traffic congestion and pollution. Their effectiveness however, remains contested. Using high frequency data from the...

Changes in transport costs can affect mobility in ways that differ across the population, affecting the impacts of transport policies. We randomly assign large price reductions on Uber in Egypt over a 3-month period and collect comprehensive data on participant mobility using Google Timeline. A...

Spatial distribution and leakage effects are of great policy concern and increasingly discussed in the economics literature. Here we study Europe's most aggressive recent air pollution regulation: Low Emission Zones are areas in which vehicular access is allowed only to vehicles that emit low...

This study investigates the impact of economic incentives on travel-related physical activity, leveraging the London Congestion Charge's disincentivising of sedentary travel modes via increasing the cost of private car use within Central London. The scheme imposes charges on most types of cars...

We provide evidence that graduated driver licensing (GDL) laws, originally intended to improve public safety, impact human capital accumulation. Many teens use automobiles to access both school and employment. Because school and work decisions are interrelated, the effects of automobile-specific...

A new paradigm for transport economists has been established: revenues of a welfare-maximising road tax should be employed to reduce the level of a distortionary income tax. An essential modelling assumption to reach this conclusion is that the number of workdays is optimally chosen, whereas...

This study estimates the dose-response relationship between Body Mass Index (BMI) and crash risk in commercial motor vehicle operators. Intake data was collected on 744 new truck drivers who were training for their commercial driver's licenses at a school operated by the cooperating trucking...

This paper analyzes the relation between commuting time and health in the United Kingdom. I focus on four different types of health outcomes: subjective health measures, objective health measures, health behavior, and health care utilization. Fixed effect models are estimated with British...

In this paper, we propose a new spatial framework to model excess commuting of workers and we show empirical differences between the self-employed and employees in the US. In a theoretical framework where self-employed workers minimize their commuting time, employees do not minimize their...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...
