Cheat Sheet
- Binding Price Ceilings Cause Shortages -
A binding price control ceiling set below the market equilibrium price leads to a persistent shortage as quantity demanded exceeds quantity supplied. For example, rent control in large cities often causes housing scarcities and black-market sublets (Mankiw, 7th ed.). Use the mnemonic "Ceiling below = Scarcity" to cement the binding price ceiling concept.
- Binding Price Floors Lead to Surpluses -
A binding price floor placed above equilibrium, such as a minimum wage above the market rate, creates a surplus when supply outpaces demand. Agricultural price supports often result in excess crops that governments must buy or dispose of (USDA reports). Remember "Floor above = Flood of goods" to recall the price control surplus effect.
- Deadweight Loss from Price Controls -
Any binding price control - ceiling or floor - generates deadweight loss, represented by the triangular area between supply and demand curves. The formula for deadweight loss is ½ × (price distortion) × (quantity distortion), highlighting the inefficiency (Varian, 2014). Visualizing this triangle on your graph helps you spot lost gains from trade.
- Unintended Consequences of Government Price Controls -
Government price controls can trigger hidden costs, like reduced quality, long queues, or black markets, as producers circumvent ceilings or floors. A classic example is Venezuela's fuel price ceiling, which led to chronic shortages and corruption. Think "Lines, Lies, and Low Quality" to link price ceilings with real-world pitfalls.
- Assessing Surplus Changes under Binding Price Control -
To evaluate a binding price control's impact, compare consumer surplus and producer surplus before and after intervention using supply-demand diagrams. Binding ceilings shift surplus from producers to consumers but still create net welfare loss; binding floors favor producers yet harm consumers. Practicing these area calculations on sample problems (Khan Academy) solidifies your mastery.
