Explain how progressive income taxes can act as an automatic stabiliser during a recession without a new policy decision.

- The tax rule remains unchanged but receipts respond to income. This offsets part, not necessarily all, of the initial fall in private spending.
Marking points
- Falling incomes reduce tax payments under the existing system.
- Disposable income falls less than gross income, cushioning consumption and demand.
Examiner tip: Automatic stabilisation is not the same as a discretionary tax-rate cut.

Fictional government: tax receipts are 420 million, spending excluding interest is 460 million and interest payments are 20 million. Calculate the primary and overall budget balances, defining balance as receipts minus spending.

- Exclude interest only for the primary measure. Under the stated sign convention a negative balance is a deficit; it is a flow over a period rather than the debt stock.
Marking points
- Primary balance = 420 - 460 = -40 million.
- Overall balance = 420 - 460 - 20 = -60 million.
- Both are deficits; the overall deficit includes interest.
Examiner tip: Do not confuse a budget deficit with total outstanding debt.

Fictional case: the policy interest rate falls, but banks tighten lending standards and most households have fixed-rate loans. Analyse why consumption and investment might respond weakly.

- Transmission depends on borrowing costs, credit access and borrowers' responses; tighter lending standards can offset lower rates. Existing contracts and bank risk decisions can interrupt the link between the policy rate and private expenditure.
Marking points
- Lower policy rates can reduce borrowing costs if passed through.
- Tighter standards restrict access even when quoted rates fall.
- Fixed-rate borrowers receive no immediate reduction in existing repayments.
- Weak confidence can delay new borrowing despite cheaper credit.
Examiner tip: Explain a broken link in transmission, not merely 'time lags'.

Fictional case: a government funds apprenticeships and faster freight infrastructure. Analyse how each can affect long-run aggregate supply and why budget expenditure alone does not prove success.

- Trace inputs to productivity and then capacity. Poor course matching or an unused freight route can absorb funds without relieving a binding constraint.
Marking points
- Apprenticeships can raise skills and labour productivity.
- Faster freight lowers delivery delays and improves productive efficiency.
- Successful improvements can raise potential output and shift long-run supply right.
- Completion, relevance and actual infrastructure use determine outcomes, not spending totals alone.
Examiner tip: Measure outcomes such as skill gains or journey reliability, not just money allocated.

Fictional case: Navo is in recession with low interest rates and substantial public debt. Evaluate temporary infrastructure spending financed by borrowing.

- Low rates improve financing terms but are not a guarantee of value. Prioritise ready, high-return projects and assess future debt service; delayed construction could arrive after the recession.
Marking points
- Indicative: spending can support demand when resources are idle.
- Useful infrastructure can also increase future capacity.
- Debt service, construction lags or poor project selection can limit gains.
- A justified judgement compares expected social returns and financing sustainability rather than debt size alone.
Examiner tip: Separate short-run demand support from long-run project returns.

Fictional case: Rima proposes deregulating entry into electricity retail while keeping the transmission network regulated. Evaluate the potential benefits and limits of this split.

- Different stages of supply have different cost structures. Competition in retail need not imply efficient duplication of transmission lines; fair access and monitoring are essential to prevent network power undermining entry.
Marking points
- Indicative: easier retail entry can increase choice and competitive pressure.
- A network with high fixed costs may retain natural-monopoly characteristics.
- Entrants need fair network access and consumers need clear tariffs and reliable service.
- A justified conclusion conditions benefits on access rules, consumer protection and regulatory capacity.
Examiner tip: Evaluate the specified industry stages separately.
Marking points are indicative, not an official mark scheme. Accept equivalent valid methods and supported interpretations that address the task; award each mark once without requiring the model wording.
