Monopolistic competition: Occurs when there are many firms in the industry, each selling
a slightly differentiated product. One firm's products are not perfect substitutes for
another's so this means that the firms operating in the market are not price takers.
Large number of relatively small firms
Product differentiation exists (each firms products are slightly different from the next,
usually due to branding, advertising, quality etc.)
Few, if any barriers to entry.
Short run supernormal profits only.
How the market operates:
Firms may aim their differentiated products at different market segments and aim to sell
more than one type of the same product to get good market coverage. Firms are not price
takers, they have some control over their prices, but only as far as their brand image and
brand loyalty will stretch. In the short run firms may earn large profits. As other firms can
easily enter the market, large profits do no last very.
Short Run:
It is neither productive of Allocativly efficient. They have control over what price and output
they set.

products. Due to completion, firms under this market structure have to enhance their
visibility in the market through aggressive advertising and marketing.…read more
