Market Share and Price Setting Behavior for Private Labels and National Brands

In this paper, we focus on the nature of demand and competitive response in the market for private label and national “branded” grocery products. Specifically,we employ less restrictive functional forms than usedin prior research. Specifically, we incorporateLA/AIDS demands and the corresponding price reactionequations to estimate consumer price sensitivities andsupply side price strategies for national brand andprivate label products. Oligopolistic priceinterdependence is explored further by specifyingbrand share, brand Herfindahl, and a measure of thestructure of the local retail markets in the supplyside relations to evaluate explicitly the impact ofmarket structure.
