The impact of source effects and message valence on word of mouth retransmission
The impact of word of mouth (WOM) on consumer actions is more pronounced now than ever due to technology. Modern advancements have made engaging in WOM and contributing to viral marketing very commonplace. This notion can be troubling for firms, as consumers can say anything about any firm with virtually no chance of repercussions. Therefore, it is important to study the flow of WOM to help firms design strategies to influence its transmission. This study compares the impact of WOM sender expertise and valence of the WOM message on consumer likelihood to contribute to viral marketing by retransmitting messages to others. Results of our study find that messages from experts and non-experts are equally influential when the valence is positive (PWOM), but messages from experts are more influential than those from non-experts when the valence is negative (NWOM). Explanations for this result are given, as are contributions to both theory and practice.
