What Full Employment Means
Definition
Full employment: the situation where everyone willing and able to work at the going wage rate can find a job, so that vacancies roughly match the number searching; it does not mean 0% unemployment.
Labour force: the economically active population, made up of those in work plus those unemployed and actively seeking work.
- At full employment only frictional, structural and seasonal unemployment remain, so the measured rate is positive rather than 0%.
- The economy is then producing on its production possibility curve, using labour close to its full productive capacity.
- Because idle labour is minimised, output and incomes sit near their maximum → the government also collects more income tax and pays out fewer benefits.
Key Idea
- Full employment is a positive rate, often around 3%–5%, not 0%.
- It is one of the main macroeconomic objectives, alongside stable prices, growth and a healthy current account.
Why It Is Not Zero
- Workers are always moving between jobs, so some are frictionally unemployed while they search → this never falls to 0%.
- Skills and location mismatches leave some workers structurally unemployed even while vacancies exist elsewhere.
- So a positive unemployment rate is fully consistent with full employment.
Example
- An economy has a labour force of 32 million, of whom 1.28 million are unemployed.
- If that 4% is all frictional and structural, the economy is at full employment and the £ value of lost output is small.
Benefits and the Trade-off
- Reaching full employment raises real output and household incomes → firms earn higher revenue and tax receipts rise.
- However, pushing aggregate demand beyond full employment causes labour shortages → firms bid wages up → cost-push inflation.
- It depends on labour market flexibility: with fast retraining the economy can grow with little inflation, but with rigid labour markets the trade-off is sharper.
Exam technique
- Define full employment as vacancies matching those searching, not zero unemployment.
- Quote a realistic figure such as 3%–5% to show the rate is positive.
Common Mistake
- Do not write that full employment means 0% unemployment.
- Frictional, structural and seasonal unemployment always remain.
Self review
- Define full employment.
- Why is it not zero unemployment?
- What kinds of unemployment remain at full employment?
- Why is full employment a macroeconomic objective?
