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....

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...

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...

This study analyzes supermarket firm prices to determine whether prices are related to market structure and whether the Demsetz quality critique is valid. Factor analysis is used to identify five service factors that are modeled with price as endogenous variables in a simultaneous equations...

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...

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...

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...
