Question

In other words, you are not only protecting your own child by getting her vaccinated, you are protecting other children—and adults too. a.equilibrium b.law of demand c.law of supply d.negative externality e.positive externality

Answer 1

E. positive externality

Answer 2

The correct answer is E.

An externality is defined as any consequence of the economic activity, which can be either positive or negative, that is beared by an external third party. For example, when an individual is getting vaccinated, it generates a positive externality as it provides protection for the society as a whole (it does not only affect the patient who receives the vaccine or the doctor that administers it, who are the "internal" parties involved in the operation).
