Bundling and Menus of Two‐Part Tariffs
研究了企业通过两部收费菜单或捆绑销售让消费者自选，发现不考虑成本时捆绑更有利，但社会福利可能更高或更低。
Inducing self‐selection among different segments of consumers is an important issue in pricing. Some firms induce self‐selection by offering a menu of two‐part tariffs (e.g., different rate plans) and letting consumers select the tariff and quantity they prefer. Other firms induce self‐selection by offering a menu of price‐quantity bundles (e.g., different package sizes) and letting consumers select only from among these bundles. We show that bundling is more profitable absent cost considerations. Social welfare may be higher or lower with bundling.
