Research Note—Competitive Bundling and Counterbundling with Generalist and Specialist Firms
研究综合企业与两家专业企业在两个产品类别中的竞争，分析捆绑销售策略在无退出威胁时的盈利性及反捆绑效果，发现均衡时同时捆绑可盈利，但不对称产品线可能更优。
Bundling, which is the practice of selling two or more products or services in a package, is a pervasive marketing practice and is often used as a strategic competitive tool. However, there has not been enough consideration of competitive bundling situations in which exit of a competitor is not a concern. In this paper, we address this issue by identifying conditions under which strategic competitors may or may not resort to bundling when competitor exit considerations are absent. We study competition between a multiproduct generalist firm and two single-product specialist firms in two product categories, one of which has undifferentiated products and the other has differentiated products. In our model, the specialist firms can form an alliance to bundle their products in competing with the generalist firm. In contrast to the previous literature, we find that concurrent bundling by competitors, if it occurs in equilibrium, is profitable. We also find that when one competitor bundles and the other does not, the bundling firm gains a greater share of customers and makes a higher profit. However, when conditions favor counterbundling by a competitor, such counterbundling helps the competitor retain its customers. Finally, we note that under other market conditions, concurrent bundling by competitors escalates price competition to the extent that retaining customers through bundling is not profitable. In such a case, we show that strategic competitors are better off having asymmetric product lines with one competitor bundling and the other selling unbundled.
