Arrange the following steps in the correct order for implementing a tax to address a negative externality in copper production: A) Assess the marginal social cost of copper production. B) Determine the optimal tax rate to align private costs with social costs. C) Implement the tax on copper producers. D) Evaluate the impact of the tax on production levels and deadweight loss.

To implement a tax that addresses the negative externality in copper production, we start by assessing the marginal social cost of copper production. This means we look at the total cost to society, including any harm caused by the production, like pollution. Next, we determine the optimal tax rate that would make copper producers consider these social costs in their decisions, aligning private costs with social costs. After setting the tax, we implement it on copper producers, which encourages them to reduce production or adopt cleaner methods. Finally, we evaluate how the tax affects production levels and any resulting deadweight loss, helping us understand if the tax is working as intended.
