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...

This study examines the ability of the Canadian Wheat Board (CWB) to price discriminate in bread wheat exports. This study models wheat as a vertically differentiated intermediate good and modifies the model of vertical differentiation by Mussa and Rosen to the realities of wheat import demand....

In this paper we specify a price determination model which can test both the traditional positive interbrand price share hypothesis and the negative intrabrand relationship predicted by residual demand analysis. We evaluate this relationship empirically using three-dimensional panel data from...

This research report is the econometric analysis of product market definition and unilateral market power that the senior author presented as expert economic witness for the state of New York in State of New York v. Kraft General Foods et al. at trial in September 1994. It is the first, and to...

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...

In an imperfectly competitive industry, differentiated products compete with each other with price rather than quantity as the strategic variable. Several previous studies have employed a generalized Nash Bertrand model: Liang (1989), Cotterill (1994), Cotterill, Putsis and Dhar (2000), and...

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...

This article decomposes the impact of imports on domestic price-cost margins into separate price and cost effects. Using data from 24 food-processing industries, the empirical results show that although the direct impact of imports on prices is always negative, a positive net impact on...

This report analyzes the economic impact of price fixing in the wet corn milling industry on consumers in the State of Michigan. Two of the companies who produce citric acid have pleaded guilty to fixing its price. In this report we assume that price fixing also occurred among HFCS producers....

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...
