The Market for 'Lemons' (Adverse Selection in the Used Car Market)
The 'market for lemons' is a famous economic model that illustrates how hidden attributes can lead to market failure. The model focuses on the used car market, where 'lemon' is a slang term for a vehicle discovered to be defective after it has been purchased. In this market, sellers possess private information about their vehicle's true quality, while buyers do not. This information gap forces prospective buyers to base their offers on the average quality of cars in the market, which can discourage owners of high-quality cars from selling and may result in a market dominated by low-quality 'lemons'.

The Causal Chain of Market Failure in the 'Lemons' Problem
In a market for used goods, sellers possess private information about the true quality of their items, while buyers do not. This information gap can lead to a situation where low-quality goods drive out high-quality goods. Arrange the following statements to illustrate the logical sequence of this market failure.
Consider a used car market with 100 cars for sale. Half of the cars are high-quality, which buyers value at $10,000, and their owners will not sell for less than $8,000. The other half are low-quality, which buyers value at $2,000, and their owners will not sell for less than $1,000. Buyers cannot tell the quality of any individual car before purchase but know the overall distribution. Assuming buyers are risk-neutral and will offer a price equal to the average value of a car on the market, what is the most likely outcome?
