Externalities and Government Intervention

The video tutorial by Paul Hanley discusses externalities, which are the costs or benefits of a decision on a bystander not considered by the decision-maker. Negative externalities, like pollution from a factory, lead to overproduction, while positive externalities, such as education, result in underproduction. The government can intervene through taxes, subsidies, or regulations to address these issues.

• To ignore them

How can the government encourage positive externalities?

• By imposing taxes

• By reducing production

• By ignoring them

What is one method the government can use to regulate markets?
