Currently, perfect price discrimination—in which each person is charged a price a smidge below their reservation price, which is also their marginal benefit—is mostly a hypothetical scenario. However, as data mining becomes more ubiquitous, we may see markets that more closely resemble perfect price discrimination through individual pricing. Use a graph to illustrate what perfect price discrimination would look like. Explain how perfect price discrimination benefits the seller and how it benefits the buyer. Then explain how perfect price discrimination impacts the total market quantity.
