We estimate an equilibrium model of residential sorting with endogenous traffic congestion to evaluate the efficiency and equity impacts of urban transportation policies. Leveraging fine-scale data on household travel diaries and housing transactions with home and work locations in Beijing, we...

In cities worldwide, the widespread use of single occupancy cars often leads to traffic congestion and its associated ill effects. Using high frequency data from Google Maps, we test whether high-occupancy vehicle (HOV) policies can be an effective tool to combat congestion. Using the unexpected...

We characterize optimal urban transportation policies in the presence of congestion and environmental externalities and evaluate their welfare and distributional effects. We present a framework of a municipal government that implements different transportation equilibria through its choice of...

This report examines strategies to improve accessibility and mobility by integrating land-use and transport policies. It outlines the institutional and legal aspects of ensuring such integration. It also discusses mechanisms for steering new development to locations served by sustainable modes...

We develop novel estimates of peak and off-peak price elasticities for urban mass transit demand in San Francisco using a large natural experiment with 3.6 million trip sessions and a natural field experiment that both have exogenous price subsidies. We then estimate the welfare impacts for...

Urban public transport services generally run at a large deficit. This has led public authorities to seek efficiencies, notably through private sector involvement. Support for the sector traditionally seeks to provide basic mobility services to all segments of society, including low-income...
