Fast Stream Policy Analysis — Questions and Answers
Question 1: The UK Government is considering a policy to mandate that all new homes built from 2026 must include electric vehicle charging points. Which of the following is the strongest argument AGAINST this policy?
- Electric vehicles don't exist yet
- The additional construction cost could reduce overall housing supply at a time of acute housing shortage (Correct answer)
- Nobody will ever want to charge a car at home
- The policy would only affect England
Correct answer: The additional construction cost could reduce overall housing supply at a time of acute housing shortage
The strongest counterargument identifies a genuine trade-off: mandatory EV charging points add to construction costs, which could reduce the number of homes built when the UK faces a significant housing shortage. This demonstrates understanding that policy choices often involve balancing competing priorities.
Question 2: A government impact assessment for a new regulation estimates compliance costs of £50 million for businesses but health benefits valued at £200 million over 10 years. A critic argues the policy should not proceed. Which criticism would be most analytically robust?
- The health benefits cannot be measured in monetary terms
- The costs fall immediately on businesses while the benefits accrue gradually over a decade, creating a mismatch in timing that the net present value calculation should address (Correct answer)
- £200 million is not very much money for the government
- Businesses should not have to comply with any regulations
Correct answer: The costs fall immediately on businesses while the benefits accrue gradually over a decade, creating a mismatch in timing that the net present value calculation should address
This criticism is analytically sophisticated because it identifies a genuine methodological issue: the timing of costs versus benefits matters in economic analysis. Discounting future benefits to present value (using HM Treasury's Green Book methodology) could significantly change the cost-benefit ratio.
Question 3: The Government wants to reduce childhood obesity rates. Which policy approach best reflects the 'nudge' theory advocated by the Behavioural Insights Team?
- Banning all advertising of unhealthy food products
- Introducing a large tax on sugary foods
- Requiring supermarkets to place healthier options at eye level and at checkout areas, making the healthy choice the easy choice (Correct answer)
- Making PE lessons compulsory for four hours daily in all schools
Correct answer: Requiring supermarkets to place healthier options at eye level and at checkout areas, making the healthy choice the easy choice
Nudge theory, developed by Thaler and Sunstein and applied by the UK's Behavioural Insights Team, works by altering the 'choice architecture' to make desired behaviours easier without restricting freedom. Changing product placement preserves consumer choice while making healthy options more convenient.
Question 4: A cross-departmental working group is evaluating three policy options to reduce rough sleeping. Which evaluation criterion is LEAST appropriate for this assessment?
- Cost-effectiveness: cost per person housed
- Evidence base: whether the approach has been evaluated in similar contexts
- Popularity: whether the policy polls well with the general public (Correct answer)
- Deliverability: whether local authorities have the capacity to implement the policy
Correct answer: Popularity: whether the policy polls well with the general public
While public opinion may be a political consideration, it is not an appropriate analytical criterion for evaluating policy effectiveness. The Civil Service should assess policies based on evidence, cost-effectiveness, and deliverability, providing impartial advice regardless of popular opinion.
Question 5: HM Treasury's Green Book sets out guidance for policy appraisal. Which of the following is a key principle of the Green Book methodology?
- Policies should always prioritise the lowest-cost option
- All impacts — economic, social, and environmental — should be appraised over the lifetime of the policy using discounted values (Correct answer)
- Only financial costs and benefits to the Exchequer should be considered
- Policies should be evaluated solely on their first-year impact
Correct answer: All impacts — economic, social, and environmental — should be appraised over the lifetime of the policy using discounted values
The Green Book requires comprehensive appraisal of all impacts (not just financial), over the full policy lifetime, using discounting to reflect the time value of money and social preferences. It explicitly rejects narrow financial analysis and short-term evaluation.
Question 6: A devolved policy area produces different outcomes in England, Scotland, Wales, and Northern Ireland due to different approaches. From a policy analysis perspective, this situation is best described as:
- A failure of the UK constitution
- A natural experiment that provides valuable comparative evidence for policy evaluation (Correct answer)
- Proof that devolution should be reversed
- Irrelevant because the policies are not directly comparable
Correct answer: A natural experiment that provides valuable comparative evidence for policy evaluation
Different jurisdictions implementing different approaches to the same problem creates a natural experiment — a powerful source of evidence for policy evaluation. Comparing outcomes across the four nations allows analysts to assess which approaches are most effective, controlling for many shared variables.
