Study Guide Overview
This study guide covers market failure and government intervention, focusing on social efficiency, externalities (positive and negative), public vs. private goods, and the effects of government intervention on market structures. It also discusses inequality measurement using the Lorenz Curve and Gini Coefficient, and the impact of different tax types. The guide includes practice questions and emphasizes key exam topics.
#AP Microeconomics: Market Failure & Government Intervention - The Night Before 🌃
Hey there! Feeling the pressure? Don't worry, we've got this. Let's make sure you're locked and loaded for the AP Micro exam. This guide is designed to be your ultimate review, hitting all the key points with clarity and a bit of fun. Let's dive in!
#Unit 6: Market Failure and the Role of Government
This unit is crucial, as it explores when the free market doesn't produce the best outcomes for society and how government steps in. It's all about understanding why markets sometimes fail and what can be done about it. Expect to see these concepts frequently on the exam!

Ever wondered why public restrooms are often a mess? It's because of the concept of market failure! When individual incentives don't align with what's best for society, we have problems. This unit explores those situations and how government can try to fix them. Think of it as the economic version of superheroes coming to the rescue! 🦸♂️
Remember the public restroom example: People tend to care less about shared resources than their own. This highlights the core issue of market failure – when individual actions lead to suboptimal societal outcomes.

#What is Social Efficiency?
- Socially Optimal Quantity: The amount of a good or service where the Marginal Social Benefit (MSB) equals the Marginal Social Cost (MSC). This is the ideal quantity for society. 💡
- Market Failure: When the free market doesn't produce the socially optimal quantity. This often happens because the market only considers private benefits and costs, not social ones.
Key Point: The goal is to produce where MSB = MSC. This is the point of social efficiency. If the market doesn't naturally reach this point, we have a market failure.
#Example: Insulin
- The market price of insulin might exclude those who can't afford it, even though they need it. This shows a market failure because the market doesn't allocate resources to those who need them most, but to those who can pay the most.
- If the price is too low, there will be a shortage; if it's too high, there will be a surplus. Finding the balance is tough!
Don't confuse private benefits/costs with social benefits/costs. Remember, the market only considers private factors, which can lead to inefficient outcomes.
