Many governments engage in policy experimentation in various forms to resolve uncertainty
and facilitate learning. However, little is understood about the characteristics of policy …

Develo** country megacities suffer from severe road traffic congestion, yet the level of
congestion is not a direct measure of equilibrium inefficiency. I study the peak‐hour traffic …

We study an energy efficient charcoal cookstove in an experiment with 1,000 households in
Nairobi. We estimate a 39 percent reduction in charcoal spending, which matches …

We develop a methodology to estimate robust city-level vehicular speed indices, exactly
decomposable into uncongested speed and congestion. We apply it to 180 Indian cities …

Designing public transport networks involves tradeoffs between extensive geographic
coverage, frequent service on each route, and relying on interconnections as opposed to …

Transportation system models rely heavily upon value of time (VOT) estimates to predict
customer behavior. Accurate VOT estimates are particularly vital for planning new services …

Since the arrival of ridehailing, US state and local governments have grappled with the
question of how to tax the new services. Dozens of jurisdictions have adopted entirely …

We recover valuations of time using detailed consumer choice data from a large European
ride hail platform, where drivers bid on trips and consumers choose between a set of …

We estimate an equilibrium sorting model of housing location and commuting mode choice
with endogenous traffic congestion to evaluate urban transportation policies. Leveraging …

This paper quantifies the value of electric vehicle (EV) charging networks and the marginal
value of network speed and density. We estimate a model of gasoline drivers' refueling …
