This paper presents a comparative analysis of three different economic studies that played major roles in the policy debate over the Compact. It draws an important distinction between before-after and counterfactual impact analysis and highlights constraining assumptions in models. Over time the...

Recent research in marketing has focused on cross-category variation in the market share of private label products, while recent work in the economics and industrial organization literature has focused on the determinants of firm price setting behavior. In this paper, the authors develop a...

This study develops a two-stage market channel model to analyze pricing in the Boston milk market where retailers are differentiated sellers. A nonlinear model of demand and costs, including firm specific and industry cost shift variables is estimated for each of the four leading supermarkets....

Measuring the degree of price coordination between firms in a differentiated products industry is particularly challenging because it is necessary to utilize a demand system that is sufficiently flexible, allows the imposition of theoretical restrictions, and allow for the derivation of the...

Market structure and strategic pricing for leading brands sold by Coca Cola and Pepsi Inc. are investigated in the context of a flexible demand specification and structural price equations. This approach is more general than prior studies that rely upon linear approximations and interactions of...

This paper reports econometric estimation of brand level demand (AIDS) elasticities for regular carbonated soft drinks using Information Resources, Inc. panel data. Own and cross price elasticities are used to measure actual and hypothetical market power that would arise from potential mergers...

This study was provided to the staff at the Federal Trade Commission in October, 1999. It expands the analysis of divestitures that was presented in an April 1999 report to the FTC (An Antitrust Economic Analysis of the Proposed Acquisition of Supermarkets General Holdings Corporation by Ahold...

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...

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...
