The crew of Apollo 13 is stuck in orbit around the moon and the NASA crew on the ground is trying to figure out how to get the astronauts home alive. Faced with only the tools in space and a limited time window, the engineers must use every available item at their disposal to maximize the amount of time before reentry to Earth’s atmosphere. This clip is a nice introduction to the idea of consumer choice, budget constraints, and utility maximization. All resources must be used in the model and their is no value to saving anything. The goal is to earn as much utility as possible given the budget constraint. The same issue faced the NASA engineers: they had to use all available resources, there was no benefit to saving items for next time, and they had to maximize the time/oxygen/energy for the astronauts.

This scene is from the movie Christmas with the Kranks involves a specific type of ham that has been sold out and Mrs. Krank needs one because it’s Christmas Eve and her daughter flew in for Christmas. She pays above the sticker price of the ham because it was the last one available in the store.

In this scene from The Big Short, the traders illustrate the concept of risk/reward payoffs using Jenga blocks. When trying to determine which investments to approach, the safest returns (the blocks at the top) are the easiest to invest in, but they don’t offer much of a return because they are so safe. The investments that are a bit risker (the blocks at the bottom) are compensated with higher returns to compensate investors who take the risk.

This is a clip from the movie “The Hudsucker Proxy” (1994). In the scene, the store owner have a hard time selling the Hula Hoop. He kept lower the price but still no one wants to buy the Hula Hoop even he end up giving them for free with any purchase. He then throw all them out of the store and one of them accidentally bump into a boy. The boy start playing with it and the other kids saw it. After that, they all run to the store for the Hula Hoop. As more and more kids tried to buy a Hula Hoop, the price goes up again and even higher than before.
This related to the idea of demand and supply. At first, the Hula Hoop was not popular for kids so there’s no one wants to buy it. However, after the kids saw the boy playing with it, their preference change. Preference can change the demand of a product. When the demand increase, the price of the product and the supply also increase.
Thanks for the clip and summary Yi Chun Liu.
