Answer:
2. False
Step-by-step explanation:
An externality is a situation in which the costs or benefits of producing or consuming a good or service are not reflected in its market price.
Viewed differently, externalities are side effects (good or bad) that occur when a person or a company carries out an activity and does not bear all the costs of it, or all the benefits that it could bring.
Therefore the important thing is to have it as a budget beyond what they are estimates.
