In this episode of “It’s Always Sunny in Philadelphia,” Mac and Charlie try to go swimming during the heat wave in Philadelphia. They grab their beer and floaties and head over to the local swim club. However, they are stopped by a worker who makes them put their beer away and then proceeds to tell them that they cannot be there because they are not members of the swim club. Frustrated with this, Mac and Charlie decide to make their own swim club, one that anyone can attend.
This clip relates to economics because the swim club is an example of an excludable, non-rival good, which is a club good. Because Mac and Charlie don’t pay the fee to be a member, they are unable to swim there. And, the worker tells them that they are at full capacity and are accepting no more members because the pool has the ability to restrict the number of members and charge higher prices. The two get disgruntled because they think the pool really isn’t at full capacity. They decide to go to an abandoned pool, one they used to swim in during their childhoods, and revamp it to make it nonexcludable and nonrival, which would make it a common resource. However, since it would become a public good, it would be easy to get overcrowded, making it rival and a common good.
Thanks to Anna DeCecco for the clip and summary.
Just found your site and really enjoy it. Quick correction to the summary. It says, “They decide to go to an abandoned pool, one they used to swim in during their childhoods, and revamp it to make it nonexcludable and nonrival, which would make it a common resource.”
If it’s nonexcludable and nonrival, it would be a public good. Once it becomes overcrowded, it becomes a common resource.
