Government Intervention

💰 Government Intervention in Markets

Part 1 of 7 — Price Controls and Their Consequences

Why Do Governments Intervene?

Markets sometimes produce outcomes society considers unfair or inefficient. Governments intervene through:

Price Ceilings

A price ceiling is a legally imposed maximum price — sellers cannot charge above it.

When Does It Matter?

When a price ceiling is binding:

• Quantity traded = Qs (the smaller of Qd and Qs)
• Consumer surplus: Some consumers benefit from lower prices, but others can't find the good
• Deadweight loss is created because mutually beneficial trades don't occur

🔑 Classic AP Example: Rent control — ceiling below equilibrium rent creates housing shortage. Landlords reduce maintenance, waitlists grow, and black markets emerge.

Price Floors

A price floor is a legally imposed minimum price — buyers cannot pay below it.

🔑 Classic AP Example: Minimum wage above equilibrium creates unemployment (surplus of labor). Employers hire fewer workers than they would at the equilibrium wage.

Taxes: Excise Taxes and Tax Incidence

An excise tax is a per-unit tax on a good. Key principles:

Tax Incidence — Who Really Pays?

The statutory incidence (who writes the check) differs from the economic incidence (who bears the burden):

$\text{Tax burden} \propto \frac{1}{\text{Elasticity}}$

Applied Recall ✍️

1. A binding price ceiling creates a _______ (shortage/surplus).

2. A binding price floor creates a _______ (shortage/surplus).

3. The side of the market with more _______ demand or supply bears more of the tax burden. (elastic/inelastic)

Policy Identification 🔍

Subsidies and Quotas

Subsidies

A subsidy is a per-unit payment from the government to producers or consumers:

• Shifts supply right (down) by the subsidy amount
• Increases quantity traded, decreases consumer price
• Creates deadweight loss (overproduction beyond efficient quantity)
• Government cost = subsidy × quantity

Quotas

A quota limits the quantity of a good that can be produced or imported:

• Creates an artificial shortage → raises price
• Benefits domestic producers at expense of consumers
• Creates deadweight loss similar to a tariff

Tariffs

A tariff is a tax on imports:

• Raises the domestic price above world price
• Domestic producers produce more, consumers buy less
• Government collects tariff revenue
• Creates deadweight loss from production inefficiency + consumption inefficiency
