Answer to Question 1

Used cars usually sell for less when compared to new cars manufactured in the same year because buyers are worried about the quality of used cars; only the sellers know about the true quality of a used car. Therefore, they are not willing to pay as much for a used car as they are for a new car. This is exactly what happened in Poorland before the entry of certified used-car dealers in the market. However, when certified used-car dealers entered into the market, buyers had better information about the quality of the cars and therefore, were willing to pay more for good-quality cars. This is an example of signaling.
