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...

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...

This paper conducts counterfactual historical analysis of several monetary policy rules by contrasting actual settings of instrument variables with values that would have been specified by the rules in response to prevailing conditions. Of particular interest is whether major policy mistakes,...

Recent trade and wages literature focuses on whether trade or technology has been the major source of increases in wage inequality in OECD countries since the 1980s. In this literature, no attention has been paid to demand side considerations. Using a simple heterogeneous goods trade model of...
