Learning Objectives
- Analyze labor demand and supply
- Understand wage determination under different market structures
- Evaluate the role of unions and minimum wage
- Week 4: Market structures
- Marginal analysis
1. Labor Demand
Firms hire until MRP_L = W (Marginal Revenue Product = Wage). MRP_L = MP_L x MR (marginal product x marginal revenue).
2. Labor Supply
Workers choose between labor and leisure. Backward-bending labor supply curve: at high wages, income effect > substitution effect.
3. Wage Determination
Perfect Competition: Wages set by market supply and demand. Monopsony: Single employer has market power, pays below competitive wage. Unions: Collective bargaining can increase wages above competitive level.
4. Minimum Wage Debate
Pro: Increases living standards for low-wage workers. Con: May reduce employment if set above equilibrium.
| Concept | Formula |
|---|---|
| MRP | MRP_L = MP_L x MR |
| Profit Maximization | Hire until MRP_L = W |
| Labor Supply Elasticity | %ΔQs / %ΔW |
Q1: MP_L=10 units, P=40, hire more?MRP = 10 x 50 > $40. Yes, hire more workers. Q2: What is a monopsony in labor markets?A single employer. They face upward-sloping labor supply and pay below competitive wage. Q3: Explain the backward-bending labor supply curve.At low wages, higher wages increase hours worked (substitution effect dominates). At high wages, workers choose more leisure (income effect dominates). Join Discord PreviousDecision Making Under UncertaintyNextPublic Policy & Regulation
