We analyze a retailer’s interactions with a national brand manufacturer (NBM) using a setting in which the retailer makes category management and store brand (SB) sourcing decisions and the NBM strategically determines whether it should produce the retailer’s SB.

The majority of online sales worldwide take place in online marketplaces that connect many sellers and buyers. Online marketplaces adopt algorithmic tools to curate how the different options in an assortment are presented to customers.
