Labour Markets and Wage Determination
How labour demand and supply, productivity, skills, bargaining, discrimination, mobility and intervention affect wages and employment.
How to study A-level Economics
Define the issue and affected agents, choose an appropriate model, build the causal chain with data, then evaluate assumptions, trade-offs and alternatives before judging.
Core concepts
Concept 1
Demand for labour is derived from demand for output and depends on productivity and the value of marginal product.
Exam cue: Identify the occupation, geographic market and time period before drawing labour demand and supply.
Concept 2
Labour supply reflects wages, non-pay conditions, skills, participation, mobility and alternative opportunities.
Exam cue: Trace how productivity or product demand changes the value of employing another worker.
Concept 3
Wage outcomes can reflect market forces, bargaining power, institutions, discrimination and public policy.
Exam cue: Evaluate wage intervention with elasticity, coverage, enforcement and wider labour-market conditions.
Risk pitfalls and guardrails
Treating all workers as one homogeneous labour market.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Assuming a higher wage always reduces employment by the same amount.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Explaining wage differences only by productivity when institutions or discrimination may matter.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Memory anchors

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
