Externalities are costs and benefits that affect people who are not directly involved in the production or consumption of a good or service. In some cases the existence of externalities is evident; for example, when individuals use motor vehicles they consume a transportation service and at the same time they contribute towards air pollution. However, in other cases things are not so clear; for example, studying at a university is an activity that can be thought to have a number of different externalities. Would you be able to list at least two externalities that you have observed at your university? Briefly explain your choices.
