Market Structure and Cost Pass-Through in Retail

Posted by D. Daniel Sokol

Gee Hee Hong (Bank of Canada) and Nicholas Li (University of Toronto) have posted Market Structure and Cost Pass-Through in Retail.

ABSTRACT: 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.
