Assigned Video
Marginal Revolution University: “Trading Pollution: How Pollution Permits Paradoxically Reduce Emissions”
Instructor note: The video will be posted or embedded in Canvas.
Purpose
This assignment asks you to respond to the assigned video using the policy tools from Week 3. The video focuses on pollution permits, also known as tradable permits or cap-and-trade. This is an example of an incentive-based policy tool. Instead of telling every firm exactly how to reduce pollution, the government sets an overall limit and allows firms to trade the right to pollute.
The purpose of this assignment is not to summarize the video. The purpose is to explain how pollution permits are supposed to work, why they may reduce pollution at lower cost than command-and-control regulation, and what problems the video may leave unresolved.
Prompt
After watching the Marginal Revolution University video, write a response that answers the following question:
How do tradable pollution permits change firms’ incentives, and what tradeoffs does the video simplify or leave unresolved?
Your response should evaluate the video’s argument using concepts from Week 3.
Required Elements
Your response must do all of the following:
- Identify the video’s main argument.
Begin by explaining the video’s central claim in your own words. Do not summarize every detail. Focus on the argument about why pollution permits may reduce emissions more efficiently than command-and-control regulation.
- Explain the policy tool.
Identify tradable pollution permits as the policy tool. Explain how the system works:
- Government sets a cap on total pollution.
- Firms need permits to emit pollution.
- Firms that can reduce pollution cheaply may sell unused permits.
- Firms that face higher abatement costs may buy permits.
- Trading allows pollution reduction to occur where it is cheapest.
- Explain the incentive mechanism.
Do not just say that permits reduce pollution. Explain how they change firm behavior.
A permit system gives firms a financial reason to reduce emissions. If a firm can cut pollution at low cost, it can use fewer permits and sell the extra permits. If a firm continues polluting, it must use or buy permits. This means pollution now has an opportunity cost.
- Compare permits to direct regulation.
Explain why the video presents permits as different from command-and-control regulation. Direct regulation may require every firm to reduce pollution in the same way or by the same amount. A permit system allows firms with different costs to respond differently.
Your response should explain why that flexibility may lower the total cost of reducing pollution.
- Evaluate what the video gets right.
Identify one part of the video that explains the policy tool well. This could include its explanation of dispersed information, firm incentives, trading, abatement costs, or why the same pollution rule may not make sense for every firm.
- Evaluate what the video misses or oversimplifies.
Identify one limitation in the video’s argument. Possible issues include:
- Who receives the permits at the beginning?
- Are permits auctioned or given away?
- Who ultimately pays for the policy?
- Can firms pass costs to consumers?
- Does the location of pollution matter?
- How does government decide the correct pollution cap?
- How difficult is monitoring and enforcement?
- Does the policy address equity concerns?
- Would a pollution tax work better?
- Can firms or interest groups influence the design of the permit system?
- Raise one follow-up question.
End your response with one question that would need to be answered before judging whether the policy works well.
For example:
- How should the government decide the total pollution cap?
- Should permits be auctioned or given away for free?
- Who bears the final cost of the permit system?
- Would a pollution tax be simpler or more effective?
- What happens if pollution is concentrated in certain communities?
- How strong does monitoring need to be for the permit system to work?
Structure
Your response should be organized into clear paragraphs. A strong structure would look like this:
- Paragraph 1: Main argument of the video
- Paragraph 2: How tradable pollution permits work
- Paragraph 3: Incentive mechanism and comparison to direct regulation
- Paragraph 4: What the video gets right
- Paragraph 5: What the video misses or oversimplifies, ending with a follow-up question
You do not have to use this exact structure, but your response should be organized and easy to follow.
Course Concepts You May Use
Useful concepts from Week 3 include:
- Negative externalities
- Marginal private cost
- Marginal social cost
- Internalizing externalities
- Pollution abatement
- Tradable permits
- Cap-and-trade
- Command-and-control regulation
- Direct regulation
- Performance standards
- Incentives
- Opportunity cost
- Abatement costs
- Efficiency
- Distributional consequences
- Government failure
- Regulatory capture
- Monitoring and enforcement
You do not need to use all of these concepts. It is better to use one or two concepts carefully than to list many terms without explaining them.
What Not to Do
Do not simply summarize the video.
Do not write only that pollution is bad.
Do not say that permits work automatically without explaining the incentive mechanism.
Do not ignore the difference between reducing pollution and reducing pollution at the lowest possible cost.
Do not assume that a policy is good only because it uses a market mechanism.
Grading Criteria
This response will be graded on the following criteria:
Main Argument
The response accurately identifies the video’s central argument.
Policy Tool
The response explains tradable pollution permits as a policy tool.
Incentive Mechanism
The response explains how permits change firm behavior and create an opportunity cost for pollution.
Comparison to Regulation
The response explains how permits differ from command-and-control regulation.
Evaluation
The response identifies both what the video explains well and what it misses or oversimplifies.
Follow-up Question
The response raises a thoughtful question that extends the analysis.
Writing Quality
The response is clear, organized, and edited
