In this paper, we develop a framework for estimating market share and price reaction equations in an attempt to understand the nature of competitive interaction in the market for private label and branded grocery products. Specifically, we employ a Linear Approximate Almost Ideal Demand System...

Focusing on the interaction between national brands and private labels, this paper has two main empirical contributions: i) a simultaneous system of demand (share), price and expenditure equations is estimated, and ii) differences in the structure of the local geographic market are incorporated...

In contrast to single-equation cross-sectional studies of private label share, developing a complete understanding of the nature of the competitive interaction between national brands and private labels requires an understanding of the determinants of both demand and strategic pricing decisions...

This paper provides an overview of recent research on estimating competitive interaction in food product categories. In particular, the focus of this review is on research using scanner data conducted at the disaggregate (e.g., store, chain or local market) level, including empirical studies of...

Formulating theoretical models inevitably requires various simplifications that assist in making analysis tractable and that facilitate deriving closed form solutions. While the strategic insights gained from theoretical models of market phenomena are often quite valuable, testing the...
