how government might deal with market failure

6.1 External Influences – Economic

What is Market Failure?

Imagine a playground where children share toys. If one child keeps all the toys or leaves a pile of broken blocks, everyone else has a harder time playing. In the economy, a market fails when the “playground” (the market) doesn’t distribute resources efficiently, leaving some people worse off. 🚸

Common Types of Market Failure

How Governments Can Fix Market Failure

1. Taxes and Subsidies – Add a tax to negative externalities to make the producer pay for the damage.
   Example: Carbon tax on cars.

   $t$ = tax per ton of CO₂ emitted.

2. Regulation & Standards – Set limits on pollution or require safety checks.
   Example: Emission caps for factories. 🚫
3. Provision of Public Goods – The state supplies goods that the market would under‑provide.
   Example: National defence, public libraries. 📚
4. Price Controls – Set ceilings or floors to keep prices fair.
   Example: Rent controls in high‑cost cities. 🏠
5. Information Disclosure – Require firms to reveal product details.
   Example: Food labelling, safety certificates. 📄

Exam Tip: Linking Theory to Practice

Quick Recap

• Market failure = inefficient resource allocation.
• Key tools: taxes, subsidies, regulation, public provision, price controls, information.
• Always link the tool to the specific failure it addresses.
