Unit 4: Labor and Efficiency: Resource Markets, Inequality, and Immigration

Lesson 12a: Demand For Resources

Model Summary: Perfect Comp. in the Labor Market and Perfect Comp. in the Product Market

 

EXPLANATION/ CHARACTERISTICS / RESULTS

Competitive Product Market (Pure Competition)

- Very many producers

- Producing a standardized product

- No barriers to entry

- No market power

- The demand curve for the product is horizontal (perfectly elastic) at the market price

- Example: Agriculture

Competitive Labor Market:

- Very many qualified workers with identical skills

- Workers are therefore "wage takers" with no power to get a higher wage

- Therefore the supply of labor graph (Slabor = W) is horizontal (perfectly elastic) at the market wage

- Example: The market for unskilled labor - Walmart hiring unskilled workers

Example of Competitive Product Market in a Competitive Labor Market:

- Agriculture hiring unskilled labor

- We know that a competitive product market is allocatively efficient in the product market. They are also allocatively efficient in the labor market.

- We assume a competitive product market so Dlabor = MRP = VMP

Result:

- Profit maximizing (equilibrium) quantity to hire is Q1 (where MRP = MRC)

- Allocatively efficient quantity to hire is Q1 (where VMP = W)

- A competitive labor market in a competitive product market is efficient!
