Firms need fewer workers when demand for their output is weak.
Demand-deficient, or cyclical, unemployment arises when aggregate demand is insufficient to support employment of available labour at prevailing conditions. Falling consumption, investment or exports reduces firms' sales, so they cut output, hours and hiring. It is different from a mismatch that prevents workers filling available jobs. Some unemployment can remain even when aggregate demand is strong, so full employment does not mean literally no job search or mismatch. Evidence of broad weak sales, idle capacity and fewer vacancies supports a demand explanation; the unemployment rate alone does not identify its cause.
- Cause
- Demand-deficient, or cyclical, unemployment occurs when weak aggregate demand (AD) reduces firms' sales. They produce less and need fewer workers, even if those workers have suitable skills.
- Evidence
- A vacancy is an unfilled job a firm wants to fill. Falling sales, cancelled vacancies and idle usable equipment across many firms support a demand-deficient explanation.
- Distinction
- A worker can have suitable skills but face too few vacancies because sales are weak.
Weak sales and fewer jobs
Full employment
It is not literally zero unemployment; some ordinary search and mismatch may remain even without demand deficiency.
Persistence
A long downturn can develop structural consequences through lost skills, reduced investment or business closure.
| Type | Main mechanism | Evidence to inspect |
|---|---|---|
| Demand-deficient | Too little AD reduces production and labour demand | Orders, sales, vacancies, idle capacity |
| Structural | Worker characteristics do not match changed job requirements | Skills, experience, location, accessible vacancies |
| Frictional | Search and matching take time between suitable opportunities | Search duration, interviews, suitable vacancies |
Worked example: Falling orders remove suitable jobs
Overseas orders fall across several industries. Firms with usable equipment report lower sales, cancel vacancies and reduce production. Workers with relevant skills lose jobs even though their skills still fit these industries.
- Weaker exports reduce AD. Lower planned sales reduce the output firms want to produce.
- Labour demand is derived from output demand: firms hire workers to make what they expect to sell. With fewer orders, they cut worker-hours or make redundancies, ending jobs they no longer need.
- The stated continued skill fit and broad sales weakness support demand deficiency rather than primarily a skills mismatch.
- A recovery in orders could restore some jobs, but its timing and the firms' continued viability matter. Persistent weakness can later create additional structural problems.
Watch out for this
Unemployment caused by weak sales proves that workers have the wrong qualifications.
Workers can possess suitable skills but face too few vacancies because firms lack demand for output.
Check your understanding
Which evidence best supports demand-deficient unemployment?
- Sales and vacancies fall widely while usable capacity stands idle.
- Many jobs are available but displaced workers lack the required technical skills.
- A worker is between two suitable jobs during a short search.
