Questions from this subtopic
Each one with the model answer underneath.
- 1
How does regulation differ from legislation?
Model answer
Legislation is the law itself passed by Parliament, while regulation is the detailed body of rules, standards and enforcement applied within that law, often by an industry regulator.
- 2
What is an example of regulation, and what is one weakness of relying on it?
Model answer
Emission standards for new vehicles are an example, but regulation is costly to monitor and enforce and firms may find ways to work around the rules.
- 3
How does a tradable pollution permit scheme work, and why is it efficient?
Model answer
The authority caps total emissions and issues permits covering that amount, and firms that cut emissions cheaply sell their spare permits to firms for which abatement is expensive, so the cap is met at the lowest total cost.
- 4
What are two problems with tradable pollution permits?
Model answer
Setting the cap requires knowing the socially optimum level of emissions, and issuing too many permits collapses their price and removes the incentive to cut pollution.
- 5
How does information provision correct market failure, and what is its main limitation?
Model answer
Campaigns, labelling and compulsory disclosure move perceived private benefit towards true social benefit and so shift demand towards the optimum, but the effect is slow and may be ignored where consumption is habitual.
- 6
What does competition policy aim to do, and what are three of its tools?
Model answer
It aims to stop firms abusing market power at consumers' expense, using merger control, action against cartels and other anti-competitive agreements, and price or quality regulation of natural monopolies.
