This clip is a great introduction to monopolistic competition. Each performer provides a similar service, but they are not perfect substitutes for one another. When a new competitor enters a market, the demand for the original firms decreases and profits should fall as well.
Paper Moon — Selling Bibles
The young girl performs the role of price determinator in this clip from Paper Moon. The bibles hypothetically cannot be resold because they are inscribed with a name of the deceased. The girl looks around the living room to determine the price that the consumers would be willing (and able) to pay for the bible.
Better Call Saul — Sunk Cost Fallacy
If you’re teaching the sunk cost fallacy, this clip from Better Call Saul can be used to define the term. Kim tries to convince Jimmy to keep being a lawyer because of how much time and effort he put into the bar exam. Jimmy cuts her off to teach her about the sunk cost fallacy and how it’s a waste of time.
Super Troopers — Free Hot Dog
This clip is a great one for the first week of a principles course and can be used to teach a variety of concepts including opportunity costs, marginal analysis, and incentives. Farva isn’t the smartest police officer on the force, and he’s an even worse economist. The gas station offers a “free” hot dog for people who pump 10 gallons of gas, but Farva only needs 9 gallons to fill his car. He has to make a decision on the margin about whether he wants to get that extra gallon. He weighs the costs and benefits of the extra gallon to determine if the “free” hot dog is worth the cost of 1 gallon of gas. Ultimately, the hot dog cost his 1 gallon of gas.
The Princess Bride: Battle of Wits
The Battle of Wits scene may be one of the best game theory examples that students have scene before. It’s a great opportunity to introduce the concept of full information and knowing what the other one knows.
A Beautiful Mind: Ignoring the Blonde
The classic scene from A Beautiful Mind when Nash (Russell Crowe) and his friends are discussing governing dynamics. Nash’s realization is not that of a Nash Equilibrium, but rather the classic view of Adam Smith (everyone doing what’s best for themselves) is harmful compared to if they just work together for the common good. It can be a bit confusing since the Nash Equilibrium is not that people should work together for the great good, but this is still a good introduction to a lesson game theory because it helps introduce why it might be harmful for everyone to only do what’s in their own best interest.
Jingle All The Way: Elasticity of TurboMan
Howard (Arnold Schwarzenegger) tries to get a coveted TurboMan action figure doll the day before Christmas. It’s only the hottest selling toy of the season, so everyone is in a rush to grab this item. Because prices aren’t (initially) adjusting in their usual way, a shortage occurs across the entire city.
A limited shipment of Turbo Man action figures does arrive at one store, which decides to allocate the doll through a lottery system. Whenever there are shortages in markets, there may be a misallocation of consumption, particularly when items are distributed randomly rather than to the consumers with the highest willingness to pay. Even the though the price of the doll increases by 100%, there doesn’t appear to be any change in the quantity that people want to purchase. This would imply that the demand for TurboMan action figures is very inelastic.
Freakonomics: White Names vs. Black Names
This classic bit from Freakonomics always starts an interesting conversation when I get to the discrimination section of my labor economics course.
Just Go With It: Negotiation Scene
Maggie (Bailee Madison) negotiates a deal with Danny (Adam Sandler) when he asks her to act like his daughter. This scene does a great job opening a discussion for consumer/producer surplus in a principles class (or economic rent in a labor class).
Ferris Bueller’s Day Off: Anyone?
I like to use this clip in my first lecture to show students how I don’t want class to end up? Ben Stein plays the economist that none of us want to be! He somehow takes a really exciting subject and makes it dreadfully boring.
