论文摘要
当消费者在一个维度上有所不同时，我们研究最佳捆绑。我们对（i）集合包含和（ii）销售量定义的一组捆绑包中介绍了部分订单（如果单独出售并最佳定价）。我们表明，如果相对于此部分顺序的未主导的捆绑包被嵌套，则嵌套捆绑（分层定价）是最佳的。我们表征了哪种嵌套菜单是最佳的：如果（外出）较小的捆绑包，则出售给定的嵌套捆绑包菜单是最佳的。我们提出了这些见解的三个应用：前两个连接最佳捆绑和质量设计与价格弹性和成本结构；最后一个建立了一个必要且充分的条件，以实现昂贵的筛查，以便在本金可以同时使用价格和非价格筛选工具时。
We study optimal bundling when consumers differ in one dimension. We introduce a partial order on the set of bundles defined by (i) set inclusion and (ii) sales volumes (if sold alone and priced optimally). We show that if the undominated bundles with respect to this partial order are nested, then nested bundling (tiered pricing) is optimal. We characterize which nested menu is optimal: Selling a given menu of nested bundles is optimal if a smaller bundle in (out of) the menu sells more (less) than a bigger bundle in the menu. We present three applications of these insights: the first two connect optimal bundling and quality design to price elasticities and cost structures; the last one establishes a necessary and sufficient condition for costly screening to be optimal when a principal can use both price and nonprice screening instruments.
