Oliver Koll and I xamine the complex relationship between consumers’ attitudes toward a brand and its market outcomes. An analysis of more than 150 brands in five countries reveals the intricate reciprocal connections between customer perceptions and behaviors, brand differentiation, and market penetration in both stable and emerging markets.

While advertising is a crucial marketing component, publicly listed companies possess considerable latitude in disclosing their advertising spending in financial statements. This research shows that firms opting to voluntarily disclose advertising spending differ systematically from those that do not in multiple ways. To explore the ramifications of these disparities, we use machine learning techniques to estimate undisclosed advertising spending and examine whether advertising effectiveness differs between firms with and without voluntary advertising disclosure. The results indicate that firms opting not to disclose their advertising spending realize a significantly reduced effect of advertising on customer-based brand equity. Moreover, for these firms, advertising is associated with higher systematic risk, lower firm value, and lower advertising sales elasticity. These findings suggest that advertising is less effective in product and financial markets for firms electing to keep advertising information private. Consequently, research using only voluntarily disclosed advertising likely overestimates the impact of advertising on firm value and advertising’s sales elasticity and underestimates the impact of advertising on systematic risk for the full population of advertising firms. Correcting for this bias reduces advertising’s sales elasticity and reveals that advertising does not significantly affect firms’ systematic risk.

Changes in firms’ warranty payments are informative signals that enable investors to form timely expectations about potential changes in product quality. The authors’ survey shows that warranty payments affect potential investors’ product quality assessments and stock investment likelihood. Their quantitative analysis reveals an asymmetric stock market reaction: unanticipated increases in warranty payments (which signal quality “losses”) lower stock returns but unanticipated decreases do not affect stock returns. Two important factors moderate this relationship. First, boosting advertising spending attenuates the negative stock return effect of unanticipated increases in warranty payments. Second, unanticipated decreases in warranty payments, which signal quality “gains”, translate into higher stock returns when the industry has become less concentrated. Interestingly, changes in R&D spending do not moderate investors’ response to unanticipated increases or decreases in warranty payments. The authors advise firms to use advertising to lessen the harm from warranty payment increases and to strongly communicate warranty payment decreases in the face of intensified competition. The authors also caution that offering warranties in general does not ensure greater firm value as declining quality firms that myopically offer warranty programs experience lower firm value than those that do not provide warranties.
