If a teacher decides to have her students volunteer at a community nursing home after school which of the following would be a negative externality?

An externality is the cost or benefit that affects a party who did not choose to incur that cost or benefit. Some negative externalities in this case could be:

• Students who work after school and would either have to request time off from work or miss the activity.
• Students who have extracurricular activities after school would have to choose between the two activities.
• Parents would have to arrange to pick their children up from the activity rather than the student riding the bus home if they live in the country.
• A student would be unable to work at a part time job on that afternoon.
