Labor Markets & Factor Pricing - Complete Interactive Lesson
Part 1: Core Concepts
💰 Labor Markets
Part 1 of 7 — Supply, Demand, and Wage Determination
The Labor Market Model
| Component | Represented By | Determined By |
|---|---|---|
| Demand for labor | MRP curve (downward-sloping) | Firms' hiring decisions based on productivity |
| Supply of labor | Upward-sloping curve | Workers' willingness to work at various wages |
| Equilibrium | Intersection of D and S | Market wage and employment level |
Why Is Labor Demand Downward-Sloping?
Due to diminishing marginal returns: As more workers are added to fixed capital, each additional worker produces less additional output → MRP declines.
| Workers | MP (units) | Product Price | MRP |
|---|---|---|---|
| 1 | 20 | $10 | $200 |
| 2 | 16 | $10 | $160 |
| 3 | 11 | $10 | $110 |
| 4 | 7 | $10 | $70 |
| 5 | 3 | $10 | $30 |
If the market wage is $70/hour, the firm hires 4 workers (MRP ≥ W for workers 1-4).
🔑 Rule: Hire until MRP = W. Every worker whose MRP ≥ W generates profit; stop when the next worker's MRP < W.

Shifts in Labor Demand vs. Supply
What Shifts Labor Demand?
| Factor | Direction | Example |
|---|---|---|
| Product price increases | Demand shifts right | Rising car prices → more auto workers demanded |
| Productivity increases | Demand shifts right | New machinery makes each worker more productive |
| Price of substitute input falls | Demand shifts left | Cheaper robots replace assembly workers |
| Price of complementary input falls | Demand shifts right | Cheaper software makes programmers more productive |
What Shifts Labor Supply?
| Factor | Direction | Example |
|---|---|---|
| Immigration | Supply shifts right | More available workers at every wage |
| Population growth | Supply shifts right | Larger working-age population |
| Change in preferences |
Applied Recall ✍️
-
A firm should hire workers until MRP equals the _______.
-
Labor demand slopes down due to diminishing marginal _______.
-
Higher wages due to dangerous working conditions are called compensating _______.
Shifts Analysis 🔍
Minimum Wage: A Price Floor in the Labor Market
The minimum wage is a price floor on labor. If set above the equilibrium wage:
| Effect | Description |
|---|---|
| Unemployment | Qs of labor > Qd of labor → surplus of workers |
| Who benefits? | Workers who keep their jobs earn a higher wage |
| Who is harmed? | Workers who lose their jobs or can't find employment |
| Deadweight loss | Mutually beneficial employment transactions don't occur |
⚠️ AP Nuance: If the minimum wage is set below the equilibrium wage, it has no effect — it is not binding. The AP exam frequently tests whether students can identify binding vs. non-binding price floors.
Debate Points (AP FRQ)
- For: Reduces poverty for employed workers, addresses monopsony power
- Against: Creates unemployment among low-skill workers, may not target poverty well
