In a perfectly price discriminating market, the firm's marginal revenue curve aligns with the _____ curve, allowing it to maximize profits by capturing consumer surplus.

In a perfectly price discriminating market, the firm's marginal revenue curve aligns with the demand curve. This means that the firm can charge each consumer the maximum price they are willing to pay for each unit of a product. By doing this, the firm captures all the consumer surplus, which is the difference between what consumers are willing to pay and what they actually pay. For example, if a concert ticket is worth $100 to one person but $50 to another, the firm can charge $100 to the first person and $50 to the second, maximizing its total revenue and profits. This approach allows the firm to efficiently allocate resources and meet the varying willingness to pay among consumers.
