The Pizza Principle, sometimes known as the Pizza-Subway Connection, is a historically accurate economic law in New York City. Propose by native New Yorker, Eric M. Bram, who reported in The New York Times in 1980 that since the early 1960’s the price of a slice of pizza has matched the the cost of a New York subway ride.
In 1985 writer, historian, and film critic George Fasel learned of the correlation and wrote an op-ed for The New York Times. In 2002, New York Times columnist Clyde Haberman, commented on the two previous columns and coined the term “Pizza Connection”.
The law has held true through the years and was held true in a study by Jared Lander, a professional statistician and Adjunct Professor at Columbia University.
In 2019 The Wall Street Journal pessimistically reported that they didn’t believe it could continue due to a combination of a decrease in the fare bonus for a subway ride rather than an increase in the overall fare and the increased variability of the cost of pizza in New York City. I say, give it more time and we’ll see. If I ever visit New York City, I’ll buy a slice of pizza, take the subway and report back.
