Monopolistic Competition Slide 2 presents the quantity of output for a firm under monopolistic competition. Slide 3 explains the firm's pricing decision. Slide 4 illustrates the firm's marginal revenue at its level of output. Slide 5 illustrates total revenue. Slide 6 illustrates the firm's ATC. Slide 7 illustrates the firm's total costs as the firm's ATC x quantity of product. Slide 8 illustrates the area of total revenue above the firm's total costs. This area represents the firm's profit. The remainder of the slides pose questions and provide answers based on the graph. Monopolistic Competition Price/ Costs/ Revenue in $s Locate the intersection of marginal revenue (MR) and marginal cost (MC) and draw a line through the intersection from the demand curve (D) to the X axis (Quantity). This is the quantity of output for the monopolistically competitive firm. MC P ATC MR Q D Quantity Monopolistic Competition Price/ Costs/ Revenue in $s Locate the intersection of marginal revenue (MR) and marginal cost (MC) and draw a line through the intersection from the demand curve (D) to the X axis (Quantity). This is the quantity of output for the monopolistically competitive firm. MC P ATC MR Q D Quantity Draw a line from the demand curve to the Y axis. This is the price the monopolistically competitive firm will charge. Monopolistic Competition Price/ Costs/ Revenue in $s MC P ATC MR MR Q D Quantity The firm will produce output to the point where marginal revenue (MR) is equal to marginal cost (MC). If the firm produced output at a level less than where MR=MC, it would be forgoing revenue and, therefore, reducing its profits. If it produced output at a level greater than where MR=MC, its additional costs would be greater than its additional revenue, and it would be reduce its profits. Monopolistic Competition Price/ Costs/ Revenue in $s This is the total revenue (TR) received by the firm. It is the quantity of product sold multiplied by the product's price. MC P ATC MR Q D Quantity Monopolistic Competition Price/ Costs/ Revenue in $s This is the firm's average total cost (ATC) at this level of output. MC P ATC ATC MR Q D Quantity Monopolistic Competition Price/ Costs/ Revenue in $s This area represents the firm's total cost (TC) at this level of output. MC P ATC MR Q D Quantity Monopolistic Competition Price/ Costs/ Revenue in $s This area represents the firm's profit.
