Choose all answers that are correct: What happens when a negative externality in production is present in a market
I. The price determined by the "free market" is artificially low
II. The price determined by the "free market" is artificially high
III. The quantity determined by the "free market" is artificially low
IV. The quantity determined by the "free market" is artificially high
Group of answer choices
-I and IV
-II and IV
-II and III
-I and III
Answer : The answer is option A : "I and IV".
If a market has negative externality the market's marginal social cost (MSC) is lower than the marginal private cost (MPC). For this reason with negative externality the free market price is lower than the socially optimal price level. And with negative externality the free market quantity is higher than the socially optimal quantity level. Therefore, here the statements I and IV are correct. Hence option A is the correct answer.
