Did Congestion Pricing Work in NYC?

One year later, what does the data say?

One year ago, New York City implemented a congestion-pricing scheme.

Drivers entering Manhattan’s busiest core were required to pay a fee, and the reaction was immediate and loud. Critics warned that congestion pricing would harm businesses, keep workers at home, push traffic into surrounding neighborhoods, and barely reduce pollution.

We are now twelve months into this experiment. What does the data tell us? Let us look into what has happened since.

The Problem: A Policy Everyone Said Would Fail

Critics of the policy warned that it would affect small businesses, Broadway show attendance, and the return-to-office trend, and would not reduce traffic because people would not switch to public transportation.

Mark Levine , New York City’s Comptroller, summarized his observation over the past year on his Substack note.

According to his post, here are the year-one outcomes:

  • Restaurant bookings: +5%

  • Foot traffic: +3.4%

  • Retail vacancy: –0.9%

  • Broadway attendance: +19%

  • In-person office attendance: +10%

  • Congestion inside the zone: –11%

  • Traffic outside the zone: no significant change

  • Subway ridership: +7% on weekdays

  • Revenue for public transit: $548 million (vs. $500M projected)

These are trends and do not constitute a scientific analysis of the impact of the pricing scheme. To that end, we would have to rely on the academic research discussed below. First, I discuss the economic rationale for implementing congestion pricing.

The Economics

From an economics perspective, congestion pricing isn’t a radical idea. It is a common solution economists recommend.

Driving in a dense city creates costs that drivers don’t fully pay for: slower traffic for others, more pollution, more noise, and higher accident risk. Economists call these negative externalities.

That’s the core problem.

The cost to the individual driving is lower than the cost to society. A basic principle of microeconomics states that the efficient level of consumption is achieved when prices reflect all costs associated with consumption. When prices are below true costs, too much activity occurs. In this case, too many cars in Manhattan.

Congestion pricing functions like a Pigouvian tax. This tax is a fee imposed on third parties to offset the costs of an activity. Raising the private cost of driving leads to behavior changes. Some will not take that additional trip; they might shift to off-peak hours or switch to public transit.

The policy isn’t about banning cars; it’s about aligning incentives.

And the theory predicted exactly what we’re now seeing in the data.

The Evidence: What the Nature Study Shows

The strongest confirmation comes from a new peer-reviewed study published in Nature.
