prohibitions and licences

Government Policies to Achieve Efficient Resource Allocation and Correct Market Failure

Prohibitions and Licences

Prohibition: A government ban that forbids a particular activity or product. Think of it as a “no‑entry” sign for the market. 🚫

Licence: A government permission that allows a regulated activity, usually with conditions. It’s like a “driver’s licence” that lets you drive but only if you follow the rules. 🛂

When Do We Use Them?

  • Prohibitions are used when the negative impact (externality) is severe, hard to monitor, or when the activity is intrinsically harmful. Example: banning the sale of single‑use plastic bags to reduce litter.

  • Licences are used when the activity is beneficial but needs regulation to avoid misuse or externalities. Example: doctors must hold a licence to practise medicine, ensuring quality and safety.

Analogy: The School Playground

Imagine a playground where kids can bring any toy. If a child brings a dangerous toy (like a broken bike), it could hurt others. The school can prohibit that toy outright. If a child brings a new, safe toy, the school may give them a licence (a permission slip) to play with it, but only if they promise to follow safety rules. This keeps the playground safe (efficient allocation) while still allowing fun (market activity).

Exam Tip Box

Exam Question Example: “Explain how prohibitions and licences can correct market failure. Use at least one example for each.”

Answer Structure:

  1. Define the policy tool.

  2. Give a real‑world example.

  3. Explain how it addresses the externality.

  4. Discuss any costs or unintended consequences.

Key Takeaway

Prohibitions are the government’s “stop sign” for harmful activities, while licences are the “permit” that allows beneficial activities to continue under controlled conditions. Both aim to move the market toward a more efficient allocation of resources and reduce the costs of market failure. Remember to always link the policy to the specific externality it addresses when answering exam questions! 🎓
