A monopoly is a price maker as it holds a large amount of power over the price it charges.
A price maker that is a firm within monopolistic competition produces goods that are differentiated in some way from its competitors' products. This kind of price maker is also a profit-maximizer as it will increase output only as long as its marginal revenue is greater than its marginal cost, in other words, as long as it's producing a profit.
