Which of the following is a reason why individual firms under pure competition would not find it gainful to advertise their product? a. Firms produce a homogeneous product
b. The quantity of the product demanded is very large.
c. The market demand curve cannot be increased
d. Firms do not make long-run profits.

a. Firms produce a homogeneous product

Explanation:

In a perfect competition, firms produce the same goods and/or services so consumers buy the same thing regardless of which supplier they buy it from.

It would therefore be of no use to advertise because there would be no new interest in a good that everybody already makes. Instead, the advertisement could even help competitors because the benefits of the advertised products will apply to competing products as well so consumers might just go for those.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
