A government aims to correct for a negative externality in a market where the marginal external cost increases as the quantity of the good produced increases. The current unregulated market output is 1,000 units, while the socially efficient output level has been calculated to be 800 units. The government imposes a per-unit tax on producers that is exactly equal to the marginal external cost at the current output level of 1,000 units. What will be the most likely outcome of this policy?

Calculating an Optimal Externality Tax

To achieve the socially optimal level of production for a good that generates a negative externality, the per-unit tax should be set equal to the marginal external cost calculated at the current, unregulated market equilibrium quantity.

Evaluating Policy Proposals for an Environmental Tax

A government is considering different per-unit tax policies to address a negative externality where the marginal external cost increases with output. Match each tax policy to its most likely economic outcome.

To ensure a per-unit tax on a good with a negative externality successfully reduces output to the socially efficient level, the tax rate must be set equal to the marginal external cost calculated at the __________.

A policymaker wants to implement a per-unit tax to correct a negative externality and achieve the socially efficient level of production. Arrange the following steps in the correct logical order they must be followed to determine and apply the optimal tax.
