No pricing power due to the numerous number of firms hence there is no incentive for producers to charge a higher or lower than the market price (P) . Hence the term Price Taker There is no reason to charge less than the market price and consumers would walk away if he charged more. Note that the typical firm in this industry is in a position to sell all it can at the market price. Horizontal demand curve The firm faces a horizontal demand curve at the market price (P). Hence d = P (lower case d to indicate not market D) For a firm, the lower case d is used rather than D which reflected the demand for the entire market. Hence d = P = MR The price of the product equals the marginal revenue (MR) that the firm earns with each additional unit of output sold. P Q q P Market Firm S D d Short-run rule for profit maximizing output: MC = MR Profit maximization or loss minimization assumed....
