Grade 12 Economics Unit 3 : Market Failure and Consumer Protection

This unit 3 explores Market Failure, which occurs when a free market, on its own, fails to allocate resources efficiently or distribute goods equitably. You’ll learn about the main causes of market failure—such as public goods, externalities, and asymmetric information—and the role of consumer protection in addressing these issues.

Chapter 3.1 – Market Failure

This chapter defines market failure as a situation where the free market leads to an inefficient outcome. It covers the common types of market failures and discusses potential solutions (like taxes, subsidies, or regulation) that can be used to correct them.

---

Chapter 3.2 – Public Goods

Learn about public goods, a primary cause of market failure. This section defines their two key characteristics: they are non-rival (one person’s use doesn’t reduce availability for others) and non-excludable (it’s impossible to prevent people from using them). This often leads to the “free-rider problem,” where the market under-produces these goods.

---

Chapter 3.3 – Externalities

Explore externalities, which are the costs or benefits of an economic activity experienced by an unrelated third party. You’ll learn the difference between positive externalities (e.g., education, vaccination) which lead to under-consumption, and negative externalities (e.g., pollution) which lead to over-consumption.

---

Chapter 3.4 – Asymmetric Information

This section defines asymmetric information, a market failure that occurs when one party in a transaction has more or better information than the other. This imbalance can lead to poor decision-making and inefficient outcomes (e.g., the market for used cars).

---

Chapter 3.5 – Consumer Protection

This chapter explains the concept of consumer protection, which consists of laws and regulations designed to protect consumers from unfair, unsafe, or fraudulent business practices. This is a common government response to market failures like asymmetric information and monopolies.
