Resource Markets (Factor Markets)

Resource Markets (Factor Markets)

Introduction

• Resource markets, also known as factor markets, involve the buying and selling of resources like labor, land, and capital.
• These markets function similarly to product markets but focus on resources or factors of production instead of finished goods and services.

Factor Market Structures

• Similar to product markets, resource markets have different structures.
• Two main types:
  • Perfectly Competitive Resource Markets
  • Monopsony

Perfectly Competitive Resource Markets: Labor

• Characteristics:
  • Many small firms employ the resource; no single firm controls the market.
  • Many workers possess identical skills.
  • Wage is constant.
  • Workers and firms are wage takers.
• The Y-axis is wage, similar to price, but specific to resources.
  • For land or capital, the Y-axis is labeled as Rent.
• Labor is supplied by workers; demand comes from firms.

Derived Demand

• The demand for a resource is derived from the demand for the products it helps produce.
  • Example: Demand for McDonald’s workers is derived from the demand for McDonald’s food.
  • If demand for McDonald’s food decreases, demand for workers also decreases.

Shifters of Supply and Demand

• Demand Shifters:
  1. Change in demand for the product the resource produces (derived demand).
  2. Change in the productivity of the resource (more productive labor increases demand).
  3. Change in the price of related resources (hiring robots versus hiring a person).
• Supply Shifters:
  1. Number of qualified workers (population increase or decrease).
  2. Government regulation (more rules/restrictions generally decrease supply).
  3. Personal values regarding leisure, societal norms, and opportunities.

Examples of Market Shifts

• If the demand for houses decreases:
  1. The equilibrium wage of carpenters will decrease.
  2. The quantity of carpenters employed will decrease (demand for workers decreases).
• For complementary resources like cheese and flour (for pizza):
  1. If the price of cheese drops by 50%, the price of flour will increase.
  2. The quantity of flour will increase too because when cheese is cheaper, the demand for flour increases.
• If the government removes regulations for becoming a doctor:
  1. The wage for doctors will fall.
  2. The quantity of doctors will rise.
  3. The supply of doctors shifts to the right (increases).

Double Shifting

• Example: Turbo Tax popularity increases while the number of accounting graduates hits an all-time high.
  • Wage of accountants decreases.
  • The effect on quantity is unknown because both supply and demand curves are shifting.

Minimum Wage

• Governments may set a binding price floor above the equilibrium wage to support laborers.
• A price floor set below equilibrium is non-binding.

Effects of Minimum Wage

1. Leads to quantity demanded being lower than quantity supplied, resulting in a surplus of labor (unemployment).
2. Creates deadweight loss due to inefficiency; missed employment opportunities occur because employers would hire more workers at a lower wage, and some workers are willing to work for less but can’t find jobs.

The Firm in a Perfectly Competitive Resource Market

• Focus on how many workers a firm should hire.
• Two key terms:
  • Marginal Revenue Product (MRP)
  • Marginal Resource Cost (MRC)

Marginal Revenue Product (MRP)

• Definition: Additional revenue from employing one more resource/factor of production.
• Also known as Value of Marginal Product.
• Calculation requires Marginal Product of the last worker and the price of the product they produce.

Example: Tomato Farmer

• Scenario: A farmer hires laborers to produce tomatoes.
• To find MRP, multiply the Marginal Product (additional output) by the price of a bushel of tomatoes.

MRP Calculation Example

• Price of tomatoes: $20 per bushel.

Important Connection: MRP = Demand for the Firm

• Firms decide how many workers to hire based on the revenue those workers generate.
• MRP dictates how much a firm wants to hire.

Marginal Resource Cost (MRC)

• Definition: Additional cost of employing one more resource or factor of production.
• In perfectly competitive resource markets, firms and workers are WAGE TAKERS.
  • Wage (for labor) or Rent (for land/capital) is the amount firms must pay for each additional resource.

MRC Example: Farm Hands

• If the equilibrium wage rate for a laborer is $150 per day, the firm should hire workers as long as the revenue generated is greater than the cost.
• Employ resources such that MRP = MRC. This is the profit-maximizing rule for a firm.

Side-by-Side Graph Comparison

• Scenarios shift things in the market, affecting the firm.
• Example: Increase in law school graduates.
  1. Assuming a perfectly competitive market, the quantity of lawyers increases, and their equilibrium wage decreases.
  2. A law firm's hiring of lawyers will be affected by this market change.

Monopsony Resource Markets

• Characteristics:
  1. One large firm hires the workers and can manipulate the market.
  2. Workers are relatively immobile.
  3. The firm is the wage MAKER.
• Examples: NCAA (D-I college athletes), a small town with one major employer.

Graphing Characteristics

• Monopsony operates like a monopoly.
• MRC > Supply
• Assume the firm cannot wage discriminate and must pay workers the same wage.

Monopsony Example Table

Conclusion

• For a monopsony, Marginal Resource Cost will always be greater (above) the Supply Curve

Monopsony Profit Maximization

• A monopsony maximizes profit by employing at a quantity where MRP = MRC
• Monopsonies pay the wage equal to the SUPPLY CURVE.
• There is a socially optimal/efficient quantity and wage that the monopsony ignores, occurring where the resource market would be if it was perfectly competitive.

Monopsony Inefficiency

• Monopsonies hire fewer workers and pay them less than what is socially optimal, leading to a deadweight loss.

Combining Resources

• Firms employ multiple factors/resources.
• Determining optimal combination of resources: How much labor AND how much capital firms should use given a fixed resource budget.
• Two rules:
  • The Least Cost Rule for Combining Resources
  • The Profit Maximizing Rule for Combining Resources

The Least Cost Rule

• To minimize costs and maximize output, a firm should employ resources such that: \frac{Marginal Product of Labor}{Price of Labor} = \frac{Marginal Product of Capital}{Price of Capital}
• If these values are NOT equal, the firm would benefit from allocating more money to the resource with a larger output per dollar

Practice Question

• A firm producing at the least cost condition; marginal product of labor is 25 units, marginal product of capital is 20 units. If the price of labor is $100, what is the price of capital?
• Solution: \frac{25}{100} = \frac{20}{?}, Price of Capital = $80

Profit Maximizing Rule

• The least cost rule tells you how to allocate efficiently, but it does NOT necessarily maximize your profit
• The equation is as follows: \frac{MRP of Labor}{MRC of Labor} = \frac{MRP of Capital}{MRC of Capital} = 1

Example

• Last unit of labor has MRP of $60. Last unit of capital has MRP of $200. The MRC of both is $100. Is the firm utilizing resources to maximize profit?
• Solution: The firm should reduce labor and increase capital until the MRP per dollar = 1 for both.
