We investigate the impact of price discrimination by a large Chicago supermarket chain. First we measure the impact of the chain's current zone-pricing policy on shelf prices, variable profits and consumer welfare across its stores. Using the chain's database to simulate a finer store-specific...

Market structure analysis continues to be a topic of considerable interest to marketing researchers. One of the most common representations of the manner in which brands compete in a market is via market maps that show the relative locations of brands in multi-attribute space. In this paper, we...

This paper investigates whether the tendency to buy store brand is category specific, or an enduring consumer trait. We develop a multicategory brand-choice model with a factor-analytic structure on the covariance matrix of the coefficients. The methodology allows us to elicit the basic latent...

We investigate the role of potential weekly brand-specific characteristics that influence consumer choices, but are unobserved or unmeasurable by the researcher. We use an empirical approach, based on the estimation methods used for standard random coefficients logit models, to account for the...

Discrete choice models of aggregate demand, such as the random coefficients logit, can handle large differentiated products categories parsimoniously while still providing flexible substitution patterns. However, the discrete choice assumption may not be appropriate for many categories in which...

The prevalence and widespread usage of email has given businesses a direct and cost effective way of providing consumers with targeted discount offers. While these discounts are expected to increase the demand for the promoted products, are they effective in increasing revenues? Do they have...
