Market valuation models of the effect of advertising and promotional spending: A review and meta-analysis

A narrative review is presented, within the organizing framework of a meta-analysis, of econometric models reported in the business literature that estimate the effect of advertising and promotional spending on the market value of the firm. Results from published market valuation models are aggregated, and various model specifications are appraised. In brief the meta-analysis finds support for a positive relationship between levels of advertising and promotional spending and the market value of the firm. That is, marketing activities (represented here by observed advertising and promotions spending) are generally expected to deliver future cashflows and produce increases in shareholder wealth. The review seeks to enhance understanding among the community of marketing scholars of the properties of market valuation models published in the literature and serves as a springboard for ongoing investigation of a crucial question for marketing theory and practice.
