Abstract: Celebrity endorsers can cause negative publicity that can spill over to the endorsed brand. However, little is known about the economic effects of firm reactions to these events. This study fills this gap and estimates how announcements of firms’ reactions (yes versus no), timing (slow versus fast), and type (maintain/suspend versus no reaction) affect daily abnormal stock returns (ARs) following negative publicity. Using 128 events of negative endorser publicity between 1988 and 2016 affecting firms in 230 cases, this study offers new and economically relevant insights. The most surprising finding is that firms can gain value depending on their response. Announcements of firms’ reactions positively affect ARs, especially if they occur quickly after negative publicity surfaces. The analyses reveal that fast (slow) announcements of firms’ reactions increase (decrease) firm value by 2.10% (−1.88%) over the next four trading weeks. Results also show that issuing statements suspending or maintaining the endorser both yield more positive ARs than not reacting at all. Further analyses identify conditions under which the stock market rewards maintaining or suspending an endorser. Firms have more positive ARs when they (1) suspend higher-blame endorsers, (2) suspend endorsers whose negative publicity is related to their occupation, (3) maintain endorsers with a high product fit, and (4) do not suspend apologetic endorsers. This study discusses implications for theory and practice and provides a strong empirical foundation for understanding the consequences of firm reaction announcements to negative celebrity endorser publicity.
