A Buyer Power Theory of Exclusive Dealing and Exclusionary Bundling
研究了两家竞争制造商通过垄断零售商销售产品时，买方势力如何使排他性交易和排他性捆绑变得有利可图，并导致低效率的排斥。
We develop a unified theory of exclusive dealing and exclusionary bundling. In a framework with two competing manufacturers that supply their product(s) through a monopolist retailer, we show that buyer power restores the profitability of such practices involving inefficient exclusion. The mechanism underlying this exclusion is that the compensation required by the retailer to renounce selling the rival product erodes with its buyer power. We further show that our theory holds when buyer power differs across manufacturers or when the retailer can strategically narrow (or expand) its product assortment.
