Teaching Economics with Media
When Homer finds out from Apu that there is a local business buying old grease, Homer sets out to be rich. He buys $30 worth of bacon, feeding it to the dog, in order to harvest the extra grease and sell it. He spends hours frying up bacon only to earn 68 cents. He doesn’t seem bothered by his losses since his wife (Marge) paid for it. There’s one problem Homer hasn’t realized yet; Marge gets her money from Homer.

The local little league team has a new coach, and she plans on using statistical analysis to improve their chances of winning. She tracks player tendencies and digs into the work of Bill James to bring a Moneyball approach to the Isotots. Bart laments that she has taken the fun out of the game, which begs the question of the team’s objective function. Are sports teams win-maximizers or should some teams focus on having fun?
At the end of the segment, Bart has a choice to make. Should he take the statistical approach to win the game or should he swing and try to preserve his hot streak. The hot hand fallacy is the belief that previous observations are correlated with upcoming observations. This fallacy leads us to believe batters “get hot” even though the probability of the next hit is independent of the previous ones.
Homer has found a new British show on PBS and he’s really loving it, but then they interrupt his show to ask for money. Betty White is a guest during the telethon and mentions that anyone who watches even a second of PBS and doesn’t donate is equivalent to a thief.
The Public Broadcasting Service (PBS) is a nonprofit American public television show. While the channel focuses primarily on educational programming, it relies on donations from viewers to help support its budget. PBS would be considered an example of a public good since it is nonrival and nonexcludable. One of the problems with public goods is that it is subject to underprovision because of free riders, like Homer, who consume the service but don’t contribute to its production.

In this scene, Homer and Bart are loading construction materials into their car at Builder’s Barn (a Home Depot-type store). Bart isn’t sure his dad is capable of handling the word himself when a group of immigrant day laborers offer their services. The day laborers have come from nearby Barleyville due to a recent “Barley Bust.” Homer accepts their offer and welcomes them to his home. He now feels superior because he’s able to hire workers to do jobs “we don’t want to do,” but then a hoard of laborers rushes the town of Springfield.

Homer laments of his problem of having no money and three children, but would instead prefer no kids and “3 money.” Kids, thankfully, cannot be used as money, but do represent a tradeoff in that parents could spend their money on other items instead.

This clips includes a few different economics concepts rolled in to one. The overarching theme is that of consumer choice where Homer appears to experience diminishing returns while trying to eat a 16 pound steak. He’s competing against a previous eating contest winner, who dies at the end from eating too much steak.
In the middle of the clip, Marge asks Dr. Hibbert if that much steak is healthy and Dr. Hibbert exhibits a bit of the principle-agent problem where his interests now align with eating competitions because he owns a portion of the restaurant. The good doctor tells her not to worry because they have a new heimlich machine, which decreases their need to focus on choking hazards.
Homer forgets it’s Valentine’s Day so he has to rush off to the Kwik-E-Mart to pick up a last-minute gift. Seeing that Home is desperate, Apu takes the chance to raise the price of a box of chocolates to $100. Despite Homer’s annoyance, he pays the higher price because he knows he’ll be in trouble if he comes back empty-handed. After threatening never to shop there again, Apu offers him a discount on other products to keep him from shopping next door.
Bart must have recently seen It’s a Wonderful Life because he incites a bank run reminiscent of the old classic. The banker tries to explain that the bank doesn’t actually hold everyone’s money, but its instead loaned out to the town. You can see the original clip here on Econ Media Library as well!
Springfield residents are clamoring to re-enact prohibition in town, but the City Council feels like the positive externalities outweigh the costs associated with alcohol. The County Clerk finds an old law for Springfield ordinance that actually outlaws alcohol. The new Duff Zero (alcohol-free beer) isn’t as popular as the original and the Duff factory has to shut down.
Homer and Marge head to the Frying Dutchman for the all-you-can-eat buffet. Heading late into the night, Homer doesn’t seem to be experiencing any diminishing returns even after eating all of the shrimp and two plastic lobsters. Even though he isn’t experiencing diminishing returns, Homer appears to be optimizing his utility since the marginal cost of each plate (and each plastic lobster) is $0.
