Market Structure and Cost Pass-Through in Retail
利用美国大型零售商的扫描数据，研究了垂直和水平市场结构如何共同影响零售成本传导的不完全性，发现减少双重加价会直接提高传导率，但通过增加市场份额间接降低传导率。
We examine the extent to which vertical and horizontal market structure can together explain incomplete retail pass-through. To answer this question, we use scanner data from a large U.S. retailer to estimate product level pass-through for three different vertical structures: national brands, private label goods not manufactured by the retailer and private label goods manufactured by the retailer. Our findings emphasize that accounting for the interaction of vertical and horizontal structure is important in understanding how market structure affects pass-through, as a reduction in double-marginalization can raise pass-through directly but can also reduce it indirectly by increasing market share.
