AP Microeconomics Quiz: Government Policy Tools & Their Impact

📚 Quick Study Guide: Government Policy Tools & Impact

• 💰 Price Controls: Government-mandated minimum or maximum prices.
  • ⬆️ Price Ceiling ($P_{max}$): A legal maximum price, set below equilibrium. Creates shortages, often leads to black markets. Example: Rent control.
  • ⬇️ Price Floor ($P_{min}$): A legal minimum price, set above equilibrium. Creates surpluses. Example: Minimum wage.
• 📊 Taxes (Per-Unit): A payment to the government for each unit bought or sold.
  • 📉 Impact: Increases price for buyers, decreases price for sellers, reduces quantity traded. Shifts supply (for producers) or demand (for consumers) curves.
  • ⚖️ Tax Incidence: The burden of the tax. The side of the market with more inelastic demand or supply bears a greater share.
  • 💔 Deadweight Loss (DWL): The reduction in total surplus (consumer + producer) resulting from a market distortion like a tax. Represents inefficiency.
• 🎁 Subsidies (Per-Unit): A payment from the government to producers or consumers for each unit.
  • 📈 Impact: Decreases price for buyers, increases price for sellers, increases quantity traded. Shifts supply curve down/right. Opposite of a tax.
  • ⚠️ Potential Issues: Can lead to overproduction and inefficient resource allocation.
• 🌍 Externalities: Uncompensated impacts of one person's actions on the well-being of a bystander.
  • 🏭 Negative Externalities: Costs imposed on third parties (e.g., pollution). Market overproduces. Solutions: Pigouvian taxes, regulations, tradable permits.
  • 🧑‍🎓 Positive Externalities: Benefits conferred on third parties (e.g., education, vaccinations). Market underproduces. Solutions: Subsidies, public provision.
• 🏛️ Public Goods: Goods that are both non-rivalrous and non-excludable.
  • 🚫 Market Failure: Markets typically underprovide public goods due to the free-rider problem.
  • ✅ Solutions: Government provision funded by taxes (e.g., national defense, lighthouses).
• 📜 Regulations: Government rules and laws designed to influence economic behavior directly.
  • ⚙️ Examples: Environmental standards, safety regulations, licensing requirements.
  • 🔄 Impact: Can correct market failures but may also impose costs and reduce efficiency.

1. What is the most likely outcome of a binding price ceiling?

   A) A market surplus

   B) An increase in producer surplus

   C) A shortage

   D) A decrease in consumer demand

2. If the government imposes a binding price floor in a competitive market, which of the following will occur?

   A) Quantity demanded will exceed quantity supplied.

   B) A shortage will develop.

   C) Quantity supplied will exceed quantity demanded.

   D) The equilibrium price will increase.

3. When a per-unit tax is imposed on a good, the burden of the tax falls more heavily on consumers if:
