Phil wants to ride his street strider, but his whole family thinks it is very uncool. Luke points out that he has friends on the street that might see, and Claire not so subtly threatens to leave him if he rides it suggesting she is not getting any joy from him enjoying his street strider and in fact it is harming their relationship. While Phil derives private benefits from the StreetStrider (like living healthier), he is also imposing social costs on his family. Given that his impact is relatively localized, the Coase Theorem would suggest that the Dunphy family can come to an agreement about whether Phil can keep his bike.

The Dunphy’s neighbor has a new boat that they leave in the driveway. Many of the family members are impacted by the visibility of the boat. This represents spillover effects and mean that an externality is present in the market for boats. Some family members see the boat as having a positive externality. Others see the boat as having a negative externality. As there is a relatively low number of people impacted by the boat (the Dunphy’s and other nearby neighbors), Coase theorem suggests that an efficient outcome can be negotiated. But will the Dunphy’s be able to get to it? Claire is immediately interested in finding regulations that restrict how residents can store large property like a boat. Many communities, especially home owner associations (HOAs), have rules pertaining to this situation. These rules are designed to lower the transaction costs associated with these externalities by providing a standardized process for dealing with conflicts between neighbors that settles disputes, thereby increasing the likelihood that an efficient outcome is attained. However, often these processes can end up creating problems themselves. What happens, for example, if the neighbors get together and decide that it’s OK to store the boat in a visible place? If they do and the enforcement agency requires a change, it can make things worse.

After a successful trip to Vegas, Jay decides to purchase a dog butler statue as a gift for himself. He thinks everyone loves it, but Gloria detests it and tries to get rid of it. Every time she comes home, she’s reminded of the dog and it ends up scaring her. While Jay clearly receives private benefits from his purchase (and he also thinks there are social benefits), Barkley has imposed an external cost on Gloria, which Jay has clearly not considered.
The Coase Theorem would suggest that if Gloria is truly unhappy about Barkley, she could arrange some form of payment to get Jay to put him away. We learn later that the fight between them was enough for Jay to recognize that he’s imposing a cost on Gloria, and instead decides to get rid of the butler.

Homes and yards that are improperly maintained decrease the property value of neighbors. This is a negative externality. To prevent this from happening, many modern neighborhoods have an HOA. The HOA decides what changes homeowners are allowed to make to their property and act as a non-market solution to externalities. They only allow changes that either do not impact the property value of other homes (no externalities) or that increase the property value of other homes (a positive externality). In this clip, Claire attends her HOA’s meeting. She submitted a proposal to build a “she shed” in her backyard that was denied. She believes this was not appropriate because the shed won’t be visible from the street and will not impact neighbor property values. What she doesn’t know is that her son, Luke, intercepted the request and responded with a fake denial so the HOA doesn’t understand why she is so belligerent. Phil shows up to warn her but is a little late…

Jay spends some time in the sauna au naturale, but Mitchell doesn’t appreciate the eyefull. Their awkward exchanges have been impacting other guests at the spa as well. Jay clearly gets private benefits from entering the sauna the way he has, and he doesn’t seem to care too much for the external costs he has imposed on his son. The Coase Theorem would suggest that the two should be able to come to some agreement.
