Final answer:
The use of large numerals on signs to emphasize price is the factor that contributes to a perception of a discount store, with price being used as a signal of value in the presence of imperfect information.
Step-by-step explanation:
Among the options provided, the one that will create a perception of a discount store is using signs that emphasize price by using large numerals.
This practice signals to customers that the store places a strong emphasis on value and cost savings. This perception is bolstered when price mixes with imperfect information about quality, as shoppers may subconsciously use price as a signal of value, especially in situations where they are not experts.
For instance, a shopper might assume a higher-priced item is of better quality, but the opposite logic may also apply in a discount store where low prices suggest good deals.
Storefront displays with bright and garish colors are generally less preferred by viewers, as they tend to favor soft, muted colors like delicate blue backgrounds.
Therefore, option 2, which involves using predominantly blue background for displays, may not necessarily convey a discount image. Moreover, limiting the use of direct fluorescent (white) lighting doesn't directly relate to the perception of pricing and the store's market position.
And while playing music below the audible threshold may affect the shopping mood, it does not directly convey a message about pricing.
