Identify the macroeconomic aims of growth, low inflation, low unemployment, a healthy balance of payments and equity, and explain the conflicts between them

What this dot point is asking

SEAB wants you to identify the macroeconomic aims of a government (growth, low inflation, low unemployment, a healthy balance of payments and equity) and to explain the conflicts between them. The central insight is that these aims cannot always be met simultaneously, so policy is a matter of prioritising and of using the right tool for current conditions.

The answer

The macroeconomic aims

Governments typically pursue five aims:

• Sustained and sustainable economic growth. A steady rise in real GDP (actual growth) and in potential output (capacity), without environmental damage or unsustainable imbalances.
• Low and stable inflation. A low, predictable inflation rate that preserves the value of money and supports planning.
• Low unemployment. Full use of the labour force, so the economy operates near its capacity and incomes are widely earned.
• A sustainable balance of payments. Avoiding a persistent, large current-account deficit that must be financed by borrowing or asset sales.
• An equitable distribution of income. Limiting extremes of inequality and poverty.

Many governments now add environmental sustainability as an explicit aim.

Why the aims conflict

The aims cannot always be achieved together because the policies that advance one can damage another. The major conflicts:

• Growth and unemployment versus inflation. Boosting AD to raise growth and cut unemployment can, near full capacity, generate demand-pull inflation. The short-run Phillips curve captures this unemployment-inflation trade-off.
• Growth versus the balance of payments. Faster growth raises incomes and so raises import spending, worsening the current account. A demand-led boom tends to widen a trade deficit.
• Growth versus equity. Policies that maximise growth (light taxation, flexible labour markets) can widen inequality, while heavy redistribution can blunt incentives and slow growth.
• Growth versus the environment. Rapid output growth can raise emissions and resource use, conflicting with sustainability.

How governments prioritise

Because not all aims can be met at once, governments weigh them by current circumstances: fight inflation when it is high and entrenched; support output and jobs in a recession; protect the balance of payments if a deficit becomes unsustainable. Crucially, supply-side policy can ease the conflicts: by raising potential output (LRAS), it can deliver growth and lower unemployment without inflation or import pressure, reconciling aims that conflict in the short run. This is why supply-side measures are central to a long-run strategy.

Examples in context

Example 1. Singapore's emphasis on supply-side growth. Operating close to full employment, Singapore cannot rely on demand stimulus for growth without inflation, so it prioritises raising potential output through skills, productivity and investment. This is a direct application of using supply-side policy to pursue growth while keeping inflation low and avoiding the trade-offs that demand-led growth would trigger.

Example 2. The cost-of-living and equity debate. Rapid growth and a high cost of living can widen the gap between high and low earners, putting the growth and equity aims in tension. Governments respond with targeted transfers, progressive taxation and subsidised essentials, trying to support equity without blunting the incentives that drive growth, the classic growth-equity balancing act.

Try this

Q1. State four macroeconomic aims. [2 marks]

• Cue. Sustained growth, low and stable inflation, low unemployment, and a sustainable balance of payments (and equity, and environmental sustainability).

Q2. Explain the conflict between growth and the balance of payments. [3 marks]

• Cue. Faster growth raises incomes, which raises spending on imports; rising imports worsen the current account, so a demand-led boom tends to widen a trade deficit.

Q3. Explain how supply-side policy can ease the conflict between growth and inflation. [3 marks]

• Cue. By raising potential output (shifting LRAS right), supply-side policy lets output and employment grow without bidding up prices, so growth need not cause inflation.
