A decision you can investigate
- A new order for bicycles leads workshops to recruit mechanics. A training college later qualifies more mechanics.
- Product demand and the supply of skills can move the labour market separately.
Build the explanation
- Labour demand is derived from demand for what workers produce. Higher productivity can make workers more valuable, while machine substitutes may change the demand for particular tasks.
- Labour supply depends on population and migration, age patterns, retirement and school-leaving ages, participation (including female labour-force participation), qualifications and geographic/occupational mobility. Quantity and quality matter: many available workers may not yet have the required skills.
Work through the evidence
- With labour supply unchanged, greater demand for bicycle mechanics tends to raise equilibrium wages and employment. With labour demand unchanged, more qualified mechanics shifts supply right: employment tends to rise while wage pressure eases.
- Education and training develop human capital. A trade union 工会 can collectively negotiate wages, hours and working conditions. Better conditions may support retention; disputes can interrupt production. Effects depend on bargaining power, labour-market conditions and the employer’s ability to respond.
What shifts labour supply rather than causing a wage movement along it?
A larger skilled workforce changes labour availability at each wage.
With supply unchanged, a rise in labour demand tends to cause
The new intersection lies up the existing labour-supply curve.
A larger population always supplies exactly the skills each employer needs.
Skills, participation and mobility determine who can fill particular jobs.
Test the limits
- A shift in product demand is not an automatic increase in every occupation’s wages. Training takes time and qualifications must match jobs.
- A higher wage can attract more workers along labour supply; population or qualifications can instead shift the curve. Union gains need evaluation alongside employer costs, working conditions and possible employment responses.
Which can explain a skills shortage despite many job seekers?
Occupational mismatch can limit effective labour supply.
Apply and explain your answer
- Why is mechanics’ labour demand described as derived demand 派生需求?
- Employers hire mechanics partly because customers demand bicycles and related services.
Match the terms to their meanings.
Each term describes a specific mechanism in this lesson.
Use the terms precisely
- derived demand: Demand for an input arising from demand for the output it helps produce.
- trade union: An organization representing workers in employment negotiations.
