Macroeconomic objectives and policy conflicts

Step 1. Find the number unemployed. Unemployed = labour force - employed = 24.0m - 22.2m = 1.8 million.

Step 2. Apply the unemployment rate formula. Unemployment rate = (1.8 / 24.0) x 100 = 7.5%.

Step 3. Note what the denominator is. The rate is calculated against the labour force of 24 million, not the population of 40 million. Dividing by 40 million would give 4.5%, which is a common and heavily penalised error.

Step 4. Explain the discouraged worker effect. Someone who gives up looking for work leaves the labour force. Both the numerator and the denominator fall: unemployed becomes 1.7m and the labour force becomes 23.9m, giving 7.1%. The rate has improved while the number of people out of work is unchanged and the situation is arguably worse, since a discouraged worker is further from employment than an active jobseeker.

Step 4 is the point of the question. The unemployment rate can fall for a bad reason, which is why examiners like data-response questions that pair the rate with the participation rate or with total employment.

Step 1. Apply the relationship. Growth in real GDP per capita = 3.2% - 2.1% = 1.1%.

Step 2. Check the approximation. Exactly: (1.032 / 1.021) - 1 = 0.01077, or 1.08%. The approximation of 1.1% is accurate enough at these rates.

Step 3. First reason it may overstate the gain: distribution. Per capita GDP is a mean, not a median. If the gains accrue mainly to higher-income households, the typical person may see no improvement at all while the average rises. A rising mean is consistent with a falling median.

Step 4. Second reason: what GDP counts and omits. GDP counts output regardless of whether it improves welfare. It excludes unpaid work and the informal economy, ignores leisure, and treats environmental depletion and the spending needed to clean up pollution as neutral or even positive. Growth accompanied by resource exhaustion may raise measured GDP while reducing sustainable living standards.

Step 5. Draw the policy conclusion. The growth objective is a proxy for the real objective, which is rising living standards. Where the proxy and the objective diverge, pursuing the proxy can conflict with the aim it was meant to serve. This is why the distribution and sustainability objectives sit alongside growth rather than being implied by it.

Steps 3 to 5 carry the evaluation and transfer directly into questions on living standards, development and inequality, which is a large part of topic 11.

D, E, B, C, F, A, H, G

1. The government uses expansionary fiscal or monetary policy to raise growth and cut unemployment.
2. Aggregate demand shifts right as consumption, investment and government spending rise.
3. Firms increase output to meet the extra orders, and real GDP rises.
4. As output approaches capacity, spare resources become scarce and the AS curve steepens.
5. Firms competing for a shrinking pool of available labour bid wages up faster than productivity is growing.
6. Unit labour costs rise, so firms raise prices to protect their margins.
7. The price level rises more quickly, so the inflation objective is missed even as the growth and employment objectives are met.
8. If the central bank then tightens policy to restore price stability, the growth gained is partly given back.

The final step is what makes this a conflict rather than a side effect. The two objectives are not merely in tension: the instrument used to fix one actively reverses the other. AO2 is 40% of the written papers and this chain is reusable across most policy-conflict questions.

H, F, G, B, E, A, D, C

1. A demand-led expansion raises real output and reduces unemployment below the natural rate.
2. The tighter labour market raises wage growth beyond productivity growth, so unit labour costs and then prices rise.
3. Higher domestic inflation makes exports less price competitive while rising incomes raise import demand, so the current account deteriorates.
4. The central bank raises interest rates to return inflation to target.
5. Higher rates attract capital inflows and the currency appreciates, further weakening export competitiveness.
6. Higher rates also reduce investment, so the economy's future productive capacity grows more slowly.
7. Slower capacity growth means the same demand generates inflation at a lower level of output next time, tightening the constraint permanently.
8. One expansionary decision has therefore moved inflation, the current account, the exchange rate and long-run growth, which is what 10.2 means by interrelatedness.

Questions on links between macroeconomic problems reward exactly this kind of tracing. The step most candidates miss is the last but one: that the policy response to inflation damages the capacity that would have relieved the inflation.

Define and frame: Define all three aims precisely: full employment as unemployment at the natural rate rather than zero, growth as sustainable growth in real GDP, price stability as inflation at target. State the position you will defend up front, that conflict is conditional rather than automatic, and that the condition is the amount of spare capacity.

Analysis: where they conflict: Run the demand chain from expansion through a tightening labour market to unit labour costs and inflation, supported by an AD/AS diagram with AS steepening near capacity. Add the Phillips curve to formalise the employment and inflation trade-off in the short run. Note the self-defeating loop: the tightening used to restore price stability reverses the growth and employment gains.

Analysis: where they are complementary: This is what separates a good answer, since most candidates only argue one side. Below capacity all three improve together, because AD expansion raises output and employment with little price effect. Supply-side improvement raises growth, lowers the natural rate and eases price pressure simultaneously, so the LRAS route delivers all three at once. Long-run price stability supports growth by making investment planning possible, so the aims reinforce each other over a long horizon.

Evaluation: Weigh the conditions rather than listing objections. The output gap determines whether conflict appears at all. The time horizon matters, since conflicts are short-run phenomena while complementarity dominates in the long run. The source of inflation matters, because a supply shock breaks the standard framing and makes demand tightening costly and ineffective. And the instrument matters: demand-side policy forces the trade-off, supply-side policy can avoid it but works far too slowly to help with an immediate problem.

Judgement: Conclude conditionally and specify the conditions. The aims conflict in the short run when the economy is near capacity and policy is demand-side; they are broadly complementary when there is a substantial output gap, over long horizons, and where policy is supply-side. A government's real task is therefore not choosing between the aims but choosing instruments whose conflicts it can tolerate, and sequencing them. A conclusion asserting that the aims 'always' or 'never' conflict will not reach the top level whichever way it goes.
