This paper uses a difference-in-differences strategy and an event-study analysis to evaluate the effect of Uber entries on vehicle miles traveled (VMT) in 346 US MSAs between 2011 and 2017. Empirical results demonstrate that Uber entries have no significant effect on the total VMT in a city....

Secretary of Transportation Pete Buttigieg’s proposal to make the United States a “world leader” in high‐​speed rail would add more than $4 trillion to the federal debt for construction of new rail lines plus tens of billions of dollars of annual deficit spending to subsidize operating...

We exploit the abundance of tax changes in the airline industry after the DOT's full-disclosure rule. We determine the "effective" tax rate and analyze how passengers reacted to the tax changes. Hausman-type instruments are used to address the problems arising from endogenously determined...

Maximum employee work-hour restrictions are implemented to reduce accidents. However, because they decrease the stock of work-hours available to employers, they may also have detrimental effects. A quasi-experiment suggests that pilot hours-of-service reforms, which decreased the number of...

I study delays and congestion patterns in U.S. hub airports during periods of high flight volume. I find that these periods are longer when the share of flights operated by the hub airline is greater, and these longer periods exhibit shorter delays. These results lend support to recent...
