Bundle-Size Pricing as an Approximation to Mixed Bundling
多产品企业为所有产品组合单独定价不现实，研究发现按购买数量定价的简单策略往往接近最优，比单独定价更赚钱，且能近似混合捆绑的利润。
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..
