ACDC Econ Lecture: Price Controls

Introduction

• Presented by Mr. Clifford
• Focus on understanding price controls in economics
• Example: California gas prices at the end of 2014

Price Ceilings

• Definition: A government-imposed limit on how high a price can be charged
• Example: Proposing to lower gas prices from $4 to $1
  • Effect: Consumers demand more gas (increase from 100 to 200 gallons)
  • Supply Impact: Producers supply less (decrease to 50 gallons)
  • Results in a shortage of 150 gallons
• Conclusion: Though intended to help consumers, it can lead to a reduced quantity available

Price Floors

• Definition: A government-imposed limit on how low a price can be charged
• Example: Government raising corn prices from $10 to $30 to help farmers
  • Supply Impact: Producers supply more (increase to 100 units)
  • Demand Impact: Consumers buy less (decrease to 30 units)
  • Results in a surplus
• Conclusion: Can lead to surpluses and does not always benefit producers

Key Concepts

• Competitive Markets: Typically function best without interference
• Impact of Price Controls:
  • Ceilings lead to shortages
  • Floors lead to surpluses

Common Confusion

• Price Ceilings: Must be below equilibrium to be effective
• Price Floors: Must be above equilibrium to have an impact
