OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
We quantify optimal urban transportation policies in the presence of congestion, network, and environmental externalities. We show theoretically that, beyond externality distortions, a budget constrained social planner introduces additional inefficiencies similar to those of a monopolist. We then move to an empirical analysis of the transportation system in Chicago based on an equilibrium model. To estimate supply and demand, we combine public sources and cellphone location records to construct a novel data set of the universe of public transit, ride-share, taxi, and car trips. Finally, we quantify optimal policies for a battery of scenarios. We find that congestion prices on private cars returns the largest efficiency gains relative to the status quo, but they cause a large, regressive decrease in consumer surplus.
