A decision you can investigate
- A government wants to help low-paid workers without pricing them out of jobs.
- Where should a wage floor sit relative to the market equilibrium?
Build the explanation
- A minimum wage 最低工资 is a legal wage floor; it binds only above the free-market equilibrium, where it contracts labour demand and extends labour supply, the gap being the surplus of labour. A maximum wage 最高工资 is a legal ceiling; binding below equilibrium, it creates a shortage of labour.
- Effects soften when demand for labour is inelastic, when higher pay raises motivation and productivity, or when the employer is a monopsonist: a floor can then raise both the wage and employment within limits.
Work through the evidence
- With demand W = 12 − 0.04L and supply W = 2 + 0.04L, equilibrium is 0.08L = 10, so L = 125 workers at W = 7 per hour.
- A floor at W = 9 gives demand 75 (9 = 12 − 0.04L) and supply 175 (9 = 2 + 0.04L): a surplus of 100 workers. A ceiling at W = 5 instead gives demand 175 and supply 75: a shortage of 100.
With demand W = 12 − 0.04L and supply W = 2 + 0.04L, what surplus does a wage floor of 9 create?

At W = 9 demand is 75 and supply 175, so the surplus is 100.
Test the limits
- A wage-floor diagram for an increase must show the floor moving up; examiners reject diagrams that introduce a brand-new floor. The size of job losses depends on the elasticities, which the diagram alone does not give.
- Wage controls miss other margins: employers can cut hours, benefits or training, and executives under a maximum wage can leave or take non-pay benefits, as Egypt’s 2015 public-sector cap showed.
A minimum wage of 6 binds when the equilibrium wage is 7.

A floor binds only above equilibrium; at 6 the market still clears at 7.
Every minimum wage destroys the same number of jobs in every labour market.

The surplus size depends on the elasticities, and monopsony structure can reverse the sign of the employment effect.
Apply and explain your answer
- With the numbers above, what does a minimum wage of 6 do?
- Nothing: 6 is below the equilibrium wage of 7, so the floor does not bind and the market stays at L = 125, W = 7.
Which condition can let a wage floor raise employment?

Against a monopsonist, a moderate floor can raise both the wage and employment within limits.
Use the terms precisely
- minimum wage: A legal floor under the wage, binding only above equilibrium.
- maximum wage: A legal ceiling on the wage, binding only below equilibrium.
Match the terms to their meanings.
