Maximizing the revenue from selling more than one good (or item) to a single buyer is a notoriously difficult problem, in stark contrast to the one-good case. For two goods, we show that simple “one-dimensional” mechanisms, such as selling the goods separately, guarantee at least73% of the optimal revenue when the valuations of the two goods are independent and identically distributed, and at least 50% when they are independent.
