This foreword and the subsequent four invited articles were commissioned by Eric T. Bradlow while Editor-in-Chief of <i>Marketing Science</i>. The foreword was written in four parts; each part covers a different aspect of the Workshop on Quantitative Marketing and Structural Econometrics. The workshop...

We analyze price and quality competition in a vertically differentiated duopoly in which consumers have a preference for variety. The preference for variety is a consequence of diminishing marginal utility for repeated experiences with the same product. We find consumer variety seeking can...

I analyze how ownership structure and market geography jointly influence fast food prices. I estimate a model of demand and supply that accounts for the market geography and run counterfactual experiments that demonstrate how mergers affect prices. I find that the impact of mergers can be large,...

This paper gives a proof of existence of price equilibria under certain parameters for a model of product differentiation commonly used in the empirical geographic differentiation literature. This proof is needed because the assumptions of Caplin and Nalebuff (1991) are not generally satisfied...

Marketing science models typically assume that responses of one entity (firm or consumer) are unrelated to responses of other entities. In contrast, models constructed using tools from spatial statistics allow for cross-sectional and longitudinal correlations among responses to be explicitly...

Companies and managers are apt to forget information, yet classic game theory analysis assumes that all players have perfect recall. This paper expands the literature by examining how introducing forgetfulness into a multiplayer game-theoretic framework can help or hinder cooperative behavior....
