New York’s new congestion fee appears to be reducing commuting times on key routes (see Tyler and this thread from Michael Ostrovsky). The toll only has two rates, however, on-peak (5 AM to 9 PM on weekdays and 9 AM to 9 PM on weekends) $9 and off-peak ($2.50). I like the way Vitalik Buterin explained a key weakness:
I wish the tolls were dynamic. Price uncertainty is better than time uncertainty (paying $10 more today is fine if you pay $10 less tomorrow, but you can’t compensate being 30 min late for a flight or meeting by being 30 min early to the next one).
Exactly right. Tyler and I make the same point about price controls (ceilings) in Modern Principles. A price ceiling substitutes a time price for a money price. But this isn’t a neutral tradeoff—money prices benefit sellers, while time prices are pure waste (see this video for a fun illustration).
Here in Northern Virginia the toll on I-66 to Washington is dynamic and on-average varies by more than a factor of 6 during peak hours. Everyone complains about congestion pricing when it is first introduced but people get used to it quickly. Albeit in VA we still have the option of paying no-toll which perhaps eases the transition.
