Inventory Turnover and Product Variety
研究发现零售商追求高库存周转率的动机与供应商希望扩大产品线的目标存在冲突，这种纵向失调会减少产品多样性，并分析了能纠正该问题的纵向约束措施。
Retailers face powerful incentives to limit the inventories they stock, and this leads them to focus on inventory turn as a performance measure. Their desire to pare inventory holding costs yields a misalignment of their incentives with those of a supplier seeking to have a broad line of products held. We identify the source of the vertical misalignment and demonstrate its impact on product variety. We then consider a series of vertical restraints that can potentially correct the problem. The analysis is used to explain the otherwise puzzling behavior of suppliers in several recent and significant antitrust matters.
