Young Sheldon — Germaphobe

Sheldon is a bit of a germaphobe and flu season may be the worst time for him. While one sneeze could be caused by a variety of different items, someone who is sick may be contagious and harm others. Having the flu can impose a variety of external costs on others if they get sick. These externalities often plague college classrooms around exam time though, but it’s not as convincing of a story as The Dead Grandmother/Exam Syndrome.

Shameless — Crying Baby

The eldest daughter takes care and provides for most of the family because their father is an alcoholic and mother is absent in their lives. One of the daughters, Debbie, gets pregnant and decides to have the child. After having the baby, she brings it back home and begins to live in her house with her newborn. One morning, the baby starts to cry. Everyone in the house is woken up by the newborn’s cries and is extremely angry. The baby crying in the morning is an example of a negative externality. By crying and waking everyone up, the baby is costing the third party, in this case the family, sleep, as a result.
