Abstract
The effectiveness of category pricing and promotions on store choice has been studied in prior literature. Although in theory all category promotions should attract consumers from competing stores, empirical support for this claim has been mixed. We propose that it is a subset of categories, called power categories, that drive cross-store traffic and that these are idiosyncratic to a retailer in its competitive set. Using scanner panel data, we investigate the consumer response to category pricing at competing stores via a random effects, multivariate probit model of store visits. We find that power categories tend to be high penetration categories. However, different stores have different power categories. Overall, our study recommends how retailers can find their power categories and identify segments of consumers who differ in their sensitivities to category prices.

Notes
We include 12 category prices for each competing store. We drop frozen pizza because prices for two stores B and C are highly correlated and lack of variation in prices for store A.
Due to high-dimensional estimation and restrictions on size of heterogeneity matrix, we include prices of all high-penetration, high-frequency (i.e., HH) categories. Among HL and LH categories, we include laundry detergent, toilet tissue, and yogurt as these are top contributing categories towards store sales. We do not include low-penetration, low-frequency (i.e., LL) categories.
Based on ACV—all commodity volume. This reflects an estimate of annualized sales in millions for the store across all categories. The chain name/number is not available;
Manchanda et al.[24] find no directional differences between this operationalization and others such as using the price paid when purchase occurs and weighted average otherwise.
