Multiproduct firms can set separate prices for all possible bundled combinations of its products "mixed bundling"). However, this is impractical for firms with more than a few products, because the number of prices increases exponentially with the number of products. We find that simple pricing strategies are often nearly optimal. Specifically, we show that bundle-size pricing--setting prices that depend only on the size of bundle purchased--tends to be more profitable than offering the individual products priced separately and tends to closely approximate the profits from mixed bundling.
