Summary
The demand for labor is influenced by the demand for the final product, productivity, product price, and wage relative to capital price. The demand curve for labor is downward-sloping, reflecting the derived nature of labor demand from product demand.
- Derived Demand — labor demand arises from the demand for goods or services produced. Example: If car demand increases, more workers are needed to produce cars.
- Marginal Revenue Product (MRP) — the additional revenue generated by employing one more worker. Example: If a worker produces 8 units at 80.
- Elasticity of Demand for Labor — measures how labor demand responds to wage changes. Example: If wages increase by 10% and labor demand falls by 20%, elasticity is 2.
Exam Tips
Key Definitions to Remember
- Derived Demand
- Marginal Revenue Product (MRP)
- Elasticity of Demand for Labor
Common Confusions
- Confusing MRP with total revenue
- Misunderstanding the impact of wage changes on labor demand
Typical Exam Questions
- What influences the elasticity of demand for labor? Labor costs as a percentage of total costs
- How is MRP determined? By the additional revenue from employing an extra worker
- Give an example of a change that makes labor demand elastic. Easier substitution of capital for labor
What Examiners Usually Test
- Understanding of derived demand
- Calculation and implications of MRP
