Answer:
firms differentiate their output, which makes them price makers,but barriers to entry are low or non-existent
Step-by-step explanation:
Markets that are imperfectly competitive are usually monopolistic or oligopoly.
Monopolistic Competition is simply a market with many firms or organizations that sell goods and services that are similar, but slightly different. Its products have alternative or substitutes that are close but not perfect.
In a monopolistically competitive market, firms can behave like monopolies in the short run, including by using market power to give profit.
