Fiberoptic vs Natural Trees

Manny puts up a fiberoptic Christmas tree because it is better for the environment, but Jay thinks it is ugly and does not want it in his house. This clip highlights both positive externalities of fiberoptic trees (environmental benefits) and negative externalities of the tree (Jay’s psychic costs). Jay decides instead that he and Manny should go out and cut down a tree for reasons of tradition.

Jay and Manny tried cutting down their own Christmas tree for hours, but it is not budging and keeps ruining their tools. Jay has finally had enough and says Pritchetts know when to give up. All their previous effort represent a sunk cost, and it would take too much effort relative to the reward of a half burned tree to keep going.

The Neighbor’s Boat

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.

Tankless Job

Phil is trying to sell the house next door to a couple. In order to make the house as desirable as possible, he wants to put his family’s best foot forward. He wants the buyers to want to live beside his family. So, he has the kids outside gardening. This demonstrates adverse selection, signaling and the importance of spillover effects/positive externalities. Good, helpful neighbors are desirable and can increase a property’s value, especially if they take good care of their yard. Thus, there are positive externalities associated with landscaping. To discuss signaling and adverse selection, consider that someone is less likely to move if the neighbors are good than if they are bad. So, it’s entirely reasonable to consider the housing market as being characterized by adverse selection. Phil is doing all he can to signal that he and his family are good neighbors in order to get the couple to buy the house and to pay a high price for it. But are they good neighbors?

At the end of the scene, you’ll see the other possible new neighbors. It’s clear which family each of the Dunphys would prefer to live nextdoor.

Gangster Attire Optional

On their way to Phil’s father’s wedding, Phil asks his family to dress like 1920 gangsters, but it seems like they are the only guests there in costume. Phil is notorious for embarrassing his family and each member relates a time Phil did something that made him happy, but imposed social costs on others. It’s clear that Phil’s decision to focus on his private costs and benefits are not taking into the account the social cost he is imposing on his family members.

Externalities in a Small Room

The Dunphys are having their house fumigated so they have to squeeze into a small hotel room. At first it seems like a fun opportunity to bond, but it turns out that there are a lot of comforts of home (like space) that the Dunphys really miss. Alex tries to practice her cello, Claire and Haley can’t get the wifi to work, the neighboring dogs bark all night, and a train runs through town around night time. Luke tries to set off a cologne bomb and ends up stinking up the whole room. Each member is doing some activity for their own personal gain, but end of imposing external costs on all of those around them.
