本研究以歧视性定价分析产品边界选择的决定因素。具体地说，我们考虑了这样一个模型，其中垄断者销售带有附加组件的基础产品，只有当它与基础产品一起消费时才有价值。该模型的一个重要特征是，这种附加价值取决于基础产品的估值。我们证明了当且仅当附加值的范围超过阈值时，分离比整合产生更高的利润，在这种情况下，只有当附加值的范围超过阈值时，分离才更有可能成为最优的正关联程度。至于福利，在分离的情况下，消费者盈余总是低于卖家被迫出售捆绑包裹时的盈余。
This study analyzes the determinants of product boundary choice as discriminatory pricing. Specifically, we consider a model where a monopolist sells a base product with an add‐on valuable only if it is consumed along with the base product. An important feature of this model is that this additional value is contingent on the valuation of the base product. We show that separation, in which case only the base product is sold, yields a higher profit than integration, where only a bundled package is sold, if and only if the range of the add‐on value exceeds a threshold value and that separation is more likely to become optimal as the degree of positive contingency increases. As for welfare, consumer surplus in case of separation is always lower than that when the seller is constrained to sell the bundled package.
