Total demand for labour (available jobs) < total supply of labour (available workers).
Results in a larger number of workers unable to find jobs.
Official unemployment rate = % of labour-force participants without jobs and actively seeking work.
Full employment ≠ 0\% unemployment; a "natural" amount of unemployment (frictional + seasonal + structural) is inevitable when cyclical unemployment =0.
Official Criteria for Being “Unemployed”
No paid work at all in the reference week.
Actively looking for work.
Immediately available to start work.
Excludes:
Underemployed (part-time / casual workers wanting more hours).
Hidden unemployed (discouraged job seekers).
ABS Labour-Force Survey (Australia)
~50,000 people (aged \ge 15) surveyed monthly.
Classifications:
Employed: ≥1 paid hour in the week (full-time or part-time).
Unemployed: None of the above but actively seeking.
Not in Labour Force (NILF): Neither working nor looking (e.g. full-time students, unpaid homemakers, retirees, permanently disabled).
Visual groups: working-age population → labour force → employed (full-time/part-time) & unemployed → NILF subcategories (retired, unable to work, etc.).
Key Quantitative Concepts & Formulae
Labour Force (Workforce)
All people of working age who are willing & able to work.
Participation tends to rise in booms (higher wages, more vacancies) & fall in downturns; long-run structural trends (e.g. rising female participation, part-time opportunities, delayed retirement) also matter.
Example 2 (Table June 20XX):
Employed =11{,}636 k; Unemployed =716 k.
Labour Force =12{,}352 k; Working-Age Pop =19{,}122 k.
\text{UR}=\frac{716}{12{,}352}=5.8\%.
\text{LFPR}=\frac{12{,}352}{19{,}122}=64.6\%.
Types of Unemployment
Structural
Mismatch of workers’ skills/locations with job requirements.
Driven by shifts in consumer demand & technology (e.g. self-service supermarket checkouts, autonomous trucks, AI replacing taxi drivers, bakers, fast-food cooks).
Often long-term → may require retraining or geographic mobility.
Cyclical
Linked to business cycle contractions/recessions.
Falling demand → firms cut output & lay off staff.
Frictional
Normal, short-term unemployment while individuals transition between jobs, enter or re-enter labour market (e.g. new university graduates).
Seasonal
Jobs available only during certain seasons (fruit pickers, ski instructors, summer resort staff, Christmas retail workers). Sometimes grouped with frictional.
Hidden (Discouraged) Unemployment
Individuals who want work but have stopped actively searching; therefore not counted officially.
Underemployment (related concept)
Workers employed part-time or on reduced hours who want & are available to work more.
Can rise when firms cut hours instead of staff in downturns.
Low risk (0-20%): firefighters, clergy, photographers, physicians, possibly teachers (debated: “Will the human teacher ever be replaced by a computer?”).
