Abstract

We consider a set-up with vertical contracting between a supplier and a retail industry where a large retailer competes with smaller retailers that carry a narrower range of products. Consumers are heterogeneous in their shopping costs; they will either be multistop shoppers or one-stop shoppers. The countervailing power of the large retailer is modeled as a threat of demand-side substitution. We show that retail prices are higher, and industry surplus and social welfare fall, when the large retailer possesses countervailing power. Increasing marginal wholesale prices discourages multistop shopping behavior of consumers, making demand substitution less attractive for the large retailer.
