Final answer:
Price can act as a signal of quality, especially when buyers do not have complete information. High price tags often lead consumers to believe that the associated goods or services are of superior quality, influencing purchasing decisions.
Step-by-step explanation:
The concept in question relates to the economic principle that price can act as a signal of quality when information is imperfect. This means that in various market situations, consumers may infer the quality of a product or service based on its price, especially when they lack expert knowledge in that area. High-priced items are often perceived to be of higher quality, which can influence a buyer's decision. For instance, a gemstone or a used car with a higher price tag might be assumed to be of better quality than a cheaper alternative. Price signals play into our assumptions about restaurants, clothing stores, art galleries, and even the hourly rates of lawyers, where more expensive is often equated with better.
