What policy tools can the government use to manage the economy, and what are their limits?
Government policies: fiscal policy, monetary policy and supply-side policy, how each works to influence the macroeconomic aims, and their limitations.
An SQA Higher Economics answer on government policies, covering fiscal policy (taxation and spending), monetary policy (interest rates and the money supply, set by the Bank of England), and supply-side policy (raising productive capacity), how each affects the macroeconomic aims, and the limitations of each.

What this key area is asking
The SQA wants you to know the three main types of government policy, fiscal, monetary and supply-side, how each works to influence the macroeconomic aims, and the limitations of each. You should be able to describe an expansionary or contractionary measure, trace its effect on growth, inflation, unemployment or the balance of payments, and judge it. This is the centre of the macroeconomic unit.
Fiscal policy
To cut unemployment and raise growth, the government uses expansionary fiscal policy: higher spending on infrastructure, health and education creates demand directly, and lower taxes leave households and firms with more to spend. Rising demand leads firms to increase output and hire more workers, amplified by the multiplier. To curb inflation, contractionary fiscal policy reduces demand by cutting spending and raising taxes. The main limitation is that expansionary policy widens the budget deficit and, near full capacity, can fuel inflation.
Monetary policy
Monetary policy is the control of interest rates and the money supply, set in the UK by the Bank of England (through its Monetary Policy Committee), aiming chiefly to keep CPI inflation near the 2% target.
- Raising interest rates makes borrowing dearer and saving more rewarding, so households and firms spend less; this reduces demand and eases inflation. It can also raise the exchange rate, making imports cheaper.
- Cutting interest rates makes borrowing cheaper, encouraging spending and investment to boost demand, growth and employment.
The limitation is that monetary policy works with a time lag, higher rates slow growth and raise unemployment (the inflation versus growth conflict), and very low rates may fail to revive spending if confidence is weak.
Supply-side policy
Because they raise capacity rather than just demand, supply-side policies can improve growth, employment, inflation and competitiveness together in the long run, easing the conflicts between the aims. Their limitations are that they work slowly (training a workforce takes years), can be costly, and some (such as cutting workers' protections) may be unpopular or worsen inequality.
Comparing the policies
| Policy | Tools | Acts mainly on | Main limitation |
|---|---|---|---|
| Fiscal | Government spending, taxation | Aggregate demand | Widens deficit; may raise inflation |
| Monetary | Interest rates, money supply | Aggregate demand | Time lags; growth and inflation conflict |
| Supply-side | Skills, infrastructure, incentives, reform | Productive capacity | Slow and costly to work |

Why government policies matter
Fiscal, monetary and supply-side policies are how the government pursues the macroeconomic aims, and the conflicts between those aims explain why every policy has a cost. This topic ties together the aims, government finance and national income, and it is one of the most heavily examined in the course, so being able to describe a policy, trace its effect and evaluate it is essential.

Q1. Name the three main types of government policy and state who sets monetary policy in the UK. [2 marks]
- Cue. Fiscal policy, monetary policy and supply-side policy; monetary policy is set by the Bank of England (its Monetary Policy Committee).
Q2. Explain one limitation of using expansionary fiscal policy to boost growth. [3 marks]
- Cue. Higher spending and lower taxes widen the budget deficit, adding to the national debt and its interest cost; and if the economy is near full capacity the extra demand can push up prices, raising inflation, so the growth aim conflicts with sound finances and low inflation.

SQA Higher (style)6 marksExplain how the government could use fiscal policy to reduce unemployment.Show worked answer →
Worth 6 marks. Describe expansionary fiscal policy and trace the effect on jobs.
The policy (about 3 marks). Fiscal policy is the use of government spending and taxation to influence the economy. To cut unemployment the government uses expansionary fiscal policy: it raises its own spending (on infrastructure, health, education) and cuts taxes (income tax or VAT). Higher spending creates demand for goods and services directly, and lower taxes leave households and firms with more to spend.
The effect on unemployment (about 3 marks). Higher aggregate demand leads firms to increase output, and to do so they take on more workers, reducing unemployment. The extra spending also has a multiplier effect: the newly employed spend their wages, creating further demand and jobs. The limitation is that this may widen the budget deficit and, if the economy is near full capacity, raise inflation, so the policy involves a trade-off.
SQA Higher (style)6 marksExplain how a rise in interest rates could help to reduce inflation.Show worked answer →
Worth 6 marks. Trace the transmission from interest rates to spending to prices.
Borrowing and saving (about 3 marks). Monetary policy is the control of interest rates and the money supply, set in the UK by the Bank of England. A rise in interest rates makes borrowing more expensive and saving more rewarding, so households and firms borrow and spend less and save more. Existing borrowers with variable-rate loans also have less to spend after higher repayments.
The effect on inflation (about 3 marks). Lower spending reduces aggregate demand, easing the upward pressure on prices, so demand-pull inflation falls. A higher interest rate can also raise the exchange rate, making imports cheaper and further lowering inflation. The limitation is that higher rates also slow growth and can raise unemployment, and the effect works with a time lag, so the policy must be judged against the conflict between low inflation and growth.
