3. Perfectly Competitive Labor Market
Resource Markets
Perfectly Competitive Labor Market
Perfect
Competition
Monopsony
Number of firms:
Many small firms are hiring workers
No firm is large enough to manipulate the market.
Wage maker? Wage taker?
Workers are wage takers
Firms can hire as many workers as they want at a wage set by the industry
Wages rate:
Wage is constant
Workers’ skills:
Many workers with identical skills 4

4. Resource Demand Derived Demand:
Example 1:
If there was a significant increase in the demand for pizza, how would this affect the demand for Cheese? Cows? Milking Machines? Veterinarians? Vet Schools teachers? Etc.
Example 2:
An increase in the demand for cars increases the demand for…
Derived Demand:
The DEMAND for resources (workers) is determined (derived) by the products they help to produce. 5

5. Industry Demand for Labor
What is Demand for Labor (DL)?
Demand is the different quantities of workers that businesses are willing and able to hire at different wages.
Market Demand for Labor is the sum of every firm’s MRP.
What is the Law of Demand for Labor?
There is an INVERSE relationship between wage and quantity of labor demanded.

6. Industry Supply for Labor
What is Supply for Labor (SL)?
Supply is the different quantities of individuals that are willing and able to sell their labor at different wages.
What is the Law of Supply for Labor?
There is a DIRECT or POSITIVE relationship between wage and quantity of labor supplied.

7. Marginal Resource Cost (MRC)
The additional cost of an additional resource (worker).
MRC is the WAGE.
Another way to calculate MRC is:
Marginal
Resource Cost =
Δ Total Cost
Δ Inputs

8. Marginal Revenue Product (MRP)
The additional revenue generated by an additional worker (resource).
marginal product
price of
the product.
MRP = X
Another way to calculate MRP is:
Marginal
Revenue Product =
Δ Total Revenue
Δ Inputs

9. MRP = MRC (≥) Continue to hire until…
How do you know how many resources (workers) to employ?
Continue to hire until…
MRP = MRC

12. Each lawn mowed earns your firm $50.
Example:
You hire workers to mow lawns. The wage for each worker is set at $100 a day.
Each lawn mowed earns your firm $50.
If you hire 1 worker, he can mow 4 lawns per day.
If you hire 2 workers, they can mow 5 lawns per day together.
What is the MRC for each worker?
What is the first worker’s MRP?
What is the second worker’s MRP?
How many workers will you hire?
How much are you willing to pay the first worker?
How much will you actually pay the first worker?
What must happen to the wage in the market for you to hire the second worker?
$100 (The wage set by the market)
$200

13. How many workers should you hire?
You’re the Boss
You own a business.
Assume the you are selling the goods in a perfectly competitive PRODUCT market so the price is constant at $10.
Assume that you are hiring workers in a perfectly competitive RESOURCE market so the wage is constant at $20.
Also assume the wage is the ONLY cost.
To maximize profit
How many workers should you hire? 14

19. Push-Up Machine

20. The Push-Up Machine
I am the inventor of a new generator that converts human push ups into safe and clean electrical energy.
Each push up generative $1 worth of energy.
Supply and demand in the labor market has resulted in a equilibrium wage of $10 (MRC)
The supply curve for the firm is perfectly elastic at $10…how much will you work for?
Assuming identical skills, hire the first worker (do push ups in a 4ft x 7ft box).
Let’s start hiring workers (Each worker must make sound effects)

21. The Push-Up Machine Calculate MP and MRP Quantity Labor Total Product

22. The Push-Up Machine Supply Demand
Supply and demand in the INDUSTRY GRAPH has resulted in a equilibrium wage of $10.
How much MUST each worker work for?
Why not ask for more? Why not less?
Demand
If each push up generates $1 worth of energy what is the MRP for each worker?
How much is each worker worth to the firm?

23. The Push-Up Machine Why does the MRP eventually fall?
Diminishing Marginal Returns.
Fixed resources means each worker will eventually add less than the previous workers.
The MRP determines the demand for labor
The firm is willing and able to pay each worker up to the amount they generate.
Each worker is worth the amount of money they generate for the firm.
