You don’t think there is a movie that made $15 trillion? Hm, think twice. Because there might be one movie that indirectly added that much to America’s gross domestic product in the 1980s. At least that is the theory of Nobel laureate economist Robert Mundell:

The 1976 classic, directed by Martin Scorsese with Robert De Niro as the bitterly alienated protagonist, gave the world De Niro’s catchphrase “You talking to me?,” and also introduced a young Jodie Foster. But what does it have to do with the world economy?

John Hinckley, the deranged would-be assassin who attempted to kill Ronald Reagan in 1981, claimed that he was inspired by it. … According to Mundell, the wave of sympathy for President Reagan that was engendered by the assassination attempt deterred Democrats in Congress from voting against his proposed tax cuts. Due to this accident of history, the US administered a big fiscal stimulus at the same time that Paul Volcker at the Federal Reserve was administering tight money. This, for Professor Mundell, was vital in creating the era of prosperity that followed.

“Taxi Driver is the most important movie ever made from the standpoint of creating GDP,” Mundell told delegates. “It’s the movie that made the Reagan revolution possible. That movie was indirectly responsible for adding between $5 trillion and $15 trillion of output to the US economy.”
