Evaluating Pollution Reduction Policies

A government aims to reduce the environmental damage caused by a specific chemical fertilizer that pollutes local rivers when used in corn farming. An alternative, non-polluting fertilizer is available but is currently more expensive. Which of the following policies is most likely to achieve the pollution reduction goal at the lowest overall cost to society?

Comparing Corrective Tax Policies

When a negative externality is generated by a single, specific input in a production process, a tax on the final product is just as efficient as a tax on the harmful input, provided both taxes are set to achieve the same level of pollution reduction.

Efficiency of Input vs. Output Taxes

A power plant generates electricity using a specific type of coal that releases a harmful pollutant. A cleaner, but more expensive, type of coal is available. Match each government policy option with its most likely economic outcome and the incentive it creates for the power plant.

When a negative externality is caused by a specific production input, a tax on that input is more efficient than a tax on the final product because it directly incentivizes the firm to ________ the harmful input for a cleaner alternative, rather than simply reducing overall production.

Policy Evaluation for Industrial Pollution

A furniture company uses a specific varnish that releases a pollutant. A non-polluting, but more expensive, alternative varnish is available. To address the pollution, a government is considering two policies: 1) A tax on each can of the polluting varnish used (Input Tax), or 2) A tax on each piece of finished furniture sold (Output Tax). How would the company's most likely profit-maximizing response differ between these two policies?

A manufacturing firm uses a specific chemical that pollutes a nearby river. A non-polluting, but initially more expensive, alternative chemical is available. To address the pollution, the government imposes a tax directly on the polluting chemical. Arrange the following events in the most likely chronological order to show how this policy leads to an efficient outcome.
