Spillover and Competitive Effects of Advertising in the Carbonated Soft Drink Market

Posted by D. Daniel Sokol

Rigoberto A. Lopez (University of Connecticut), Yizao Liu (University of Connecticut) and Chen Zhu (University of Connecticut) address Spillover and Competitive Effects of Advertising in the Carbonated Soft Drink Market.

ABSTRACT: This paper examines the spillover effects of television advertising on brand-level consumer demand for carbonated soft drinks (CSDs) and the competition consequences for manufacturers’ and private label CSDs. Using a random coefficients logit model (BLP) with household purchasing and advertising viewing data from five U.S. cities, we find that although brand advertising is important in increasing demand as previous work confirms, company advertising spillovers are nearly as important. Not surprisingly, advertising by competitors undermines demand for a particular manufacturer’s CSD brand but, surprisingly, there are positive spillover effects on the demand for private label brands. Further results show that eliminating all television advertising for CSDs would lower both brand and aggregate market shares (including private labels) as consumers migrate to other beverages. However, the dominant strategy is for leading companies to advertise to avoid losing revenues when competitors advertise or to increase revenues when they do not.
