free market and government intervention comparison in the same graph for any market and explain how government intervention for that problem correct the free market problems
Ans) Negative externality is when the bystander bears the cost of any activity. Eg- pollution.
Here, social cost is more than private cost. The difference between social cost and private cost is known as external cost. When this external cost is ignored, goods are overproduced in the market.
To internalise this externality, government imposes tax equal to external cost. This reduces the supply and brings the market quantity equal to socially optimal quantity.
The above graph shows negative externality, where Qmarket >Qefficient because there exists external cost.
Now, to internalise this externality, government imposes tax equal to external cost. And supply reduces. Also, Qmarket reduces and becomes equal to Qefficient.
