The website “The Economics of Seinfeld” (notice the URL is yadayadayadaecon.com) is operated by three economics professors (two at Eastern Illinois University and one at Baker University), and they explain it here:
“Seinfeld ran for nine seasons on NBC and became famous as a “show about nothing.” Basically, the show allows viewers to follow the antics of Jerry, George, Elaine, and Kramer as they move through their daily lives, often encountering interesting people or dealing with special circumstances. It is the simplicity of Seinfeld that makes it so appropriate for use in economics courses. Using these clips (as well as clips from other television shows or movies) makes economic concepts come alive, making them more real for students. Ultimately, students will start seeing economics everywhere – in other TV shows, in popular music, and most importantly, in their own lives.”
Dozens of Seinfeld episodes are identified for highlighting specific economic principles like price ceilings, incentives, imperfect information, moral hazard, marginal analysis, cost-benefit analysis, game theory, arbitrage (the famous “Bottle Deposit” episode), free entry and exit, etc.
