7. Price discrimination and welfare Suppose Barefeet is a monopolist that produces and sells Ooh boots, an amazingly trendy brand with no close substitutes. The following graph shows the market demand and marginal revenue (MR) curves Barefeet faces, as well as its marginal cost (MC), which is constant at $30 per pair of Ooh boots. For simplicity, assume that fixed costs are equal to zero; this, combined with the fact that Barefeet's marginal cost is constant, means that its marginal cost curve is also equal to the average total cost (ATC) curve. First, suppose that Barefeet cannot price discriminate. That is, it must charge each consumer the same price for Ooh boots regardless of the consumer's willingness and ability to pay. On the following graph, use the black point (plus symbol) to indicate the profit-maximizing price and quantity. Next, use the purple points (diamond symbol) to shade the profit, the green points (triangle symbol) to shade the consumer surplus, and the black points (plus symbol) to shade the deadweight loss in this market without price discrimination. (Note: If you decide that consumer surplus, profit, or deadweight loss equals zero, indicate this by leaving that element in its original position on the palette.) ? + Monopoly Outcome A Consumer Surplus Deadweight Loss 8822 8 PRICE (Dolars per pair of Ooh boots) 888 8 10 0 MC-ATC MR Demand 240 320 400 400 500 040 720 QUANTITY (Pairs of Ooh boots)

Question
Now, suppose that Barefeet can practice perfect price discrimination-that is, it knows each consumer's willingness to pay for each pair of Ooh boots
and is able to charge each consumer that amount.
On the following graph, use the black point (plus symbol) to indicate the profit-maximizing quantity sold and the lowest price at which the firm sells its
boots. Next, use the purple points (diamond symbol) to shade the profit, the green points (triangle symbol) to shade the consumer surplus, and the
black points (plus symbol) to shade the deadweight loss in this market with perfect price discrimination. (Note: If you decide that consumer surplus,
profit, or deadweight loss equals zero, indicate this by leaving that element in its original position on the palette.)
