The Sequential Process of Market Unraveling
In a market with asymmetric information, the exit of sellers with high-quality goods can trigger a cascading failure. As the best cars are withdrawn, the average quality of the remaining pool of cars decreases. This leads buyers to lower their maximum offer price, which in turn makes the price unacceptable for the owners of the now-highest-quality cars. This cycle of sellers leaving and prices falling continues sequentially until only the owners of the lowest-quality cars ('lemons') are willing to participate in the market.

Used Smartphone Market Dynamics
A market for a used product suffers from a problem where buyers cannot distinguish high-quality items from low-quality items before purchase. Arrange the following events to illustrate the logical sequence that leads to a market collapse, where only the lowest-quality items are traded.
In a market for used goods where buyers cannot distinguish high-quality items from low-quality ones, the initial group of sellers with the best items decides to exit the market because the prevailing average price is below their valuation. What is the most direct and immediate consequence of this exit?
The Cascade to Market Failure
The Next Step in Market Unraveling
In a market for used goods where buyers cannot distinguish quality before purchase, the sellers of the highest-quality items have just exited the market because the average price offered was below their minimum acceptable price. Now, only sellers of medium- and low-quality items remain. Which of the following statements best analyzes the immediate effect on the market and the likely reaction of the remaining sellers?
In a market where buyers cannot distinguish between high- and low-quality used goods, the downward spiral of prices and quality can be halted if the sellers of the remaining mid-quality goods collectively agree to hold firm and not lower their asking prices.
In a market for used goods where buyers cannot distinguish quality before purchase, the sellers of the highest-quality items have already exited. The market now consists only of medium-quality and low-quality items. Why is it likely that the sellers of the medium-quality items will be the next to exit?
Predicting Market Collapse
In a market for used digital cameras, buyers cannot tell the difference between high-quality, medium-quality, and low-quality models before purchase. The process of market unraveling has begun: sellers of high-quality cameras have exited because the average market price was too low. Now, only sellers of medium- and low-quality cameras remain. Which of the following interventions would be most effective at preventing the sellers of medium-quality cameras from also exiting the market?
