Bundling Sequentially Released Durable Goods*
研究两种顺序发布的耐用品在消费者估值正相关时，如何通过捆绑销售针对低估值消费者而不影响高估值消费者，并用2000年代零售DVD数据验证了混合捆绑能增加收入。
Suppose two durables are sequentially released and suppose that consumer valuations of these goods are positively correlated. By the time the second good is released, high‐valuation buyers are out of the market for the first good. Therefore, a bundle can be targeted at the low‐valuation consumers without violating the high‐valuation consumers' incentive compatibility constraint. We test the model's predictions on data from retail DVD sales in the 2000's. Consistent with theory, our estimates suggest that mixed bundling increases revenues, especially when the bundle components are similar (which in turn suggests positive correlation of valuations).
