My suburban Bay Area neighborhood is not walkable - but at least it is now waymable!

My op-ed with Frank Yang on congestion pricing in New York City is now in the Milken Review. Tolls on Uber/Lyft/taxi trips and on commercial vehicles and deliveries should be much higher - and then the toll on personal vehicles does not need to go up in 2028 and 2031. Link below.

Now out as an @nberpubs working paper. Carpooling (broadly understood) and congestion pricing go hand-in-hand, especially as self-driving technology has finally arrived. Without them, we risk the roads becoming one giant and slow-moving parking lot.
Increased traffic congestion can destroy all efficiency gains from self-driving cars. Carpooling and congestion pricing are highly complementary in solving this problem, from @mostrovs and Michael Schwarz nber.org/papers/w34261

I can't believe they didn't include the Dish in the photo, it's the iconic touch. Other than that, hard to disagree.

Aside from Waymo and Apollo Go (Baidu), are there any companies that are providing a (i) truly driverless (no safety driver) and (ii) publicly available (no waitlist, etc.) commercial car service over a (iii) reasonable geographical area (not just a couple of pre-set routes)?

What would NYC’s traffic congestion pricing really mean?
As part of the Insights & Bites lunch series, students joined Professor @mostrovs for a thought-provoking discussion on his research into the economics behind this timely and controversial policy.

Well, Romania stepped up to the plate (and Vatican just a few days earlier)

At a talk by @JMilei at Stanford. He is discussing price equilibrium in general and Brouwer’s and Kakutani’s theorems in particular. I look forward to the discussion of fixed-point theorems at the upcoming
@JoeBiden - @realDonaldTrump debate.

Just dropped: a podcast episode, discussing congestion pricing in New York City and beyond with @skominers and @rhackett. Link: web3-with-a16z.simplecast.co…

1. "Traffic moved faster through most major bridges and tunnels"
2. "Traffic improved along some streets within the congestion zone, but remained snarled in other areas like the length of West 42nd Street and Ninth Avenue between West 60th and 14th Streets."
One week after congestion pricing's debut in New York City, bus riders are experiencing faster rides and drivers are sitting in less gridlock at bridges and tunnels. The latest on New York's traffic experiment, with @WinnHu and @collinskeith nytimes.com/2025/01/13/nyreg…

One would normally want to wait longer to evaluate the effects of major policy changes, but the results of the first three days of Congestion Pricing in New York City are so striking that it is already possible to make some (at least preliminary) conclusions.

This suggests a straightforward fix: charge more to taxis and FHVs (during peak times). In the paper, we work out the specific numbers, and also discuss the related issue of delivery services. We propose the same $9 toll per FHV/taxi trip, or even better, $4.50 per mile.

Having said all this, the current plan is an amazing first step in the right direction - congratulations to all the policymakers for the incredible work they put into making this happen! It's great that it is already working so well on the bridges and tunnels!
