Final answer:
The government can intervene in several ways to produce a good at the socially optimal quantity, including implementing subsidies, imposing taxes, regulating production, and providing public goods.
Step-by-step explanation:
There are several ways the government can intervene to produce a good at the socially optimal quantity The government can implement a subsidy to increase the production of the good. By providing financial support to producers, the government can incentivize them to produce more, leading to an increase in the quantity produced.The government can impose taxes on the production of goods that have negative externalities. By making the production more expensive, it reduces the quantity produced to a socially desirable level.The government can regulate the production of goods that have negative externalities. By setting strict regulations and standards, the government can limit the production to a socially optimal level.The government can provide public goods directly. Public goods are goods that are non-excludable and non-rivalrous, meaning everyone can benefit from them without reducing their availability. Examples of public goods include roads, parks, and public libraries.
