Experiment with the mechanism

A monopsony employer faces an upward-sloping labor supply curve, so hiring an additional worker can require raising wages. That makes marginal labor cost exceed the wage and can produce lower employment and wages than a competitive benchmark.

LEARN WITH THE SIMULATION

Understand Monopsony Labor Market, Wage Setting & Minimum Wage by experimenting.

START HERE

A monopsony labor market gives one employer meaningful buying power over labor. Because the firm must often raise the wage to attract additional workers, the cost of hiring one more worker can exceed the wage paid to that worker. That marginal labor cost creates a gap between the monopsony outcome and the competitive labor-market benchmark.

BUILD THE IDEA

What you should understand first

  • Distinguish the labor supply curve from marginal labor cost.
  • Compare monopsony employment and wages with the competitive benchmark.
  • Explain why a moderate minimum wage can sometimes raise both wages and employment in a monopsony model.

TRY IT YOURSELF

Can a minimum wage increase employment in a monopsony market?

  1. Record monopsony employment and wage with the minimum wage at zero.
  2. Raise the minimum wage gradually but keep it below the competitive wage.
  3. Replay the labor-market sequence.
  4. Compare employment and wage with the original monopsony outcome.
Read the visual:

A moderate wage floor can flatten part of the firm's effective hiring cost, allowing employment to rise toward the competitive level while workers also receive a higher wage.

WHY IT WORKS 01

Why marginal labor cost can exceed the wage

If the labor supply curve slopes upward, attracting more workers requires offering a higher wage. In a simple monopsony, that higher wage may have to be paid not only to the new worker but also to existing workers. The extra cost of one more worker therefore includes both the new worker's wage and the additional wage cost created for the existing workforce. That makes marginal labor cost lie above the labor-supply curve.

WHY IT WORKS 02

Why monopsony can reduce both employment and wages

A competitive labor market expands employment until worker demand meets labor supply. A monopsonist instead compares worker demand with marginal labor cost, which is higher than the wage. That intersection occurs at a lower employment level. The firm then reads the wage from the labor-supply curve at that smaller workforce, producing both lower employment and a lower wage than the competitive benchmark.

WHY IT WORKS 03

Why a moderate wage floor can increase employment

A minimum wage above the monopsony wage can change the firm's effective cost of hiring additional workers. Over a range, the firm can hire more workers at the fixed minimum wage without raising the wage again for each additional hire. That can reduce the marginal hiring cost relative to the original monopsony schedule and move employment toward the competitive level before an excessively high wage floor eventually becomes restrictive.

DO NOT MIX THESE UP

Common misconception

The monopsony model does not imply every employer has complete labor-market power. Real labor markets can have many firms yet still show some monopsony power because workers face search costs, commuting limits or job switching frictions. A minimum wage that is too high can still reduce employment even when monopsony power exists.

PRACTICE CHALLENGE

Can the same minimum wage help employment in monopsony but hurt employment in a competitive model?

  • Compare the monopsony simulation with the separate minimum-wage simulation.
  • Choose a wage floor moderately above the monopsony wage.
  • Observe whether monopsony employment rises.
  • Explain why the same wage floor can create different employment effects under different market structures.
Reveal the reasoning

Yes. In a competitive benchmark, a binding wage floor raises the wage above the market-clearing level and reduces labor demanded. In monopsony, a moderate wage floor can reduce the employer's marginal hiring cost over part of the labor-supply range and increase employment. The difference comes from market structure, not from the wage floor having one universal effect.

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 supply is upward sloping and worker demand is downward sloping.
  • The employer faces marginal labor cost above the wage because raising employment requires moving up the labor-supply curve.
  • A minimum wage can alter the effective employment outcome in the simplified model.

Model limitations

  • Multiple employers, search frictions, bargaining, heterogeneous workers and hours are omitted.
  • The model illustrates monopsony mechanics rather than estimating real minimum-wage effects.

WORDS THAT MATTER

Key vocabulary

Monopsony
A market with a powerful buyer, here an employer purchasing labor.
Marginal labor cost
The extra total labor cost from hiring one additional worker.
Worker demand
The value-based demand for labor represented by the firm's marginal revenue product.
Competitive wage
The wage where labor supply and labor demand intersect without buyer power.
