Minimum Wage, Employment & Surplus
Move a minimum wage above and below the market wage to see employment, labor supplied, unemployment and deadweight loss respond.
Experiment with the mechanism
A minimum wage matters in the model only when it sits above the competitive wage. A binding floor raises the wage paid on remaining jobs while reducing labor demanded and increasing labor supplied, creating a gap between workers seeking jobs and jobs available.
LEARN WITH THE SIMULATION
Understand Minimum Wage, Employment & Surplus by experimenting.
A minimum wage is a legal floor on the wage. In a competitive labor-market diagram it affects the market only when the floor is above the equilibrium wage. A binding floor raises the wage paid on jobs that remain, reduces labor demanded, increases labor supplied, and creates a gap between workers seeking work and jobs available.
BUILD THE IDEA
What you should understand first
- Identify whether a minimum wage is binding or nonbinding.
- Distinguish employment from labor supplied and unemployment created by the quantity gap.
- Connect the reduction in employment to lost mutually beneficial matches in the simplified market.
TRY IT YOURSELF
What changes when the minimum wage moves from just below to just above the market wage?
- Set the minimum wage below the competitive wage and record employment.
- Move the floor slightly above the competitive wage.
- Replay the labor-market sequence.
- Compare labor demanded, labor supplied, unemployment and deadweight loss.
A floor below equilibrium does not change the market outcome. Once the floor becomes binding, the model shows fewer jobs demanded, more workers willing to supply labor, and a positive unemployment gap.
WHY IT WORKS 01
Why a floor can create two different quantities
At the controlled wage, employers move along the labor-demand curve and choose fewer workers, while workers move along the labor-supply curve and offer more labor. Because the wage is prevented from adjusting back to the market-clearing level, the two quantities no longer coincide. Actual employment is limited by labor demanded in this simplified competitive setup.
WHY IT WORKS 02
The incidence depends on market structure
The competitive diagram is a useful benchmark, but it is not the only labor-market model. If employers possess wage-setting power, a higher minimum wage can sometimes raise both wages and employment over part of the range. Search costs, turnover, hours, benefits and productivity responses can also change the result, which is why the simulation should be read as a mechanism model rather than a universal forecast.
DO NOT MIX THESE UP
Common misconception
The simple competitive model does not establish that every real minimum-wage increase must reduce employment by the amount shown. Search frictions, monopsony power, worker productivity, hours, compliance, sector differences and dynamic adjustment can materially change real outcomes.
PRACTICE CHALLENGE
Can a minimum wage be numerically high but still have no effect in the model?
- Raise the labor-demand intercept so the competitive wage becomes high.
- Set a minimum wage that looks large in absolute terms but remains below the new equilibrium.
- Replay the stages and inspect the binding status.
- Explain why the legal floor matters only relative to the market-clearing wage.
Reveal the reasoning
Yes. A price floor constrains the market only when it is above the equilibrium price. If the competitive wage is even higher, firms and workers already trade at a wage above the legal floor, so the floor does not alter employment, labor supplied or the model's equilibrium.
MODEL BOUNDARIES
What this simulation assumes
Every simulation simplifies reality or a mathematical system. These are the assumptions and limits to keep in mind while interpreting the results.
Model assumptions
- Labor demand and labor supply are linear and competitive.
- A minimum wage affects the market only when it exceeds the competitive wage.
- Employment under a binding floor is limited by labor demanded at the controlled wage.
Model limitations
- Monopsony, search frictions, hours, benefits, compliance, productivity effects and heterogeneous workers are omitted.
- The simulation is a benchmark mechanism, not a universal empirical prediction about minimum-wage policy.
