The Pizza Principle
For decades, the cost of a slice of plain pizza and a single subway ride were remarkably intertwined. Has the link broken?
Subway Fare
Average Slice
An Economic Anomaly
First observed in 1980 by Eric M. Bram, the "Pizza Principle" states that the average price of a slice of plain cheese pizza in New York City will generally match the cost of a single subway ride.
For nearly 40 years, the principle held with eerie accuracy. When the MTA raised the fare, local pizzerias would inevitably adjust their prices to match within a few months.
The Post-Pandemic Divergence
Since 2021, the connection has severed. A combination of massive supply chain issues for wholesale cheese and tomato paste, coupled with aggressive commercial rent hikes, pushed the average slice well past $3.00, while political pressure kept the MTA fare artificially suppressed at $2.75 until its late 2023 bump to $2.90.
What about the $1 slice?
The famous $1 slice (pioneered by 2 Bros) was always a loss-leader designed to crush local competition through extreme volume. With wholesale cheese costs up nearly 40% since 2019, almost all $1 spots have quietly raised prices to $1.50 or closed entirely. The $1 slice is dead.
