Effects of e-WOM on Consumer Information Acquisition and Product Evaluation

 Although there has been much discussion about the effects of e-WOM messages, previous studies have simply shown that positive e-WOM messages have positive effects on consumer product evaluation, while negative e-WOM messages have negative effects. Also, most studies have assumed that consumers refer to either positive or negative e-WOM messages. In contrast, my dissertation assumed that consumers refer to both positive and negative e-WOM on a single website simultaneously and found the various effects of the ratio of positive to negative e-WOM on consumer product evaluation. This dissertation contributes to the current understanding of e-WOM effects on consumer behavior by conducting several empirical studies comprehensively.
Study 1 demonstrated positive effects of negative e-WOM messages for hedonic products and for expert reading attribute centric reviews. This implies that consumers form more favorable evaluations when there is a mixture of positive and negative e-WOM messages. Study 2 demonstrated that negative e-WOM messages have a greater positive effect when they are at the top of a website as opposed to the bottom. This result implies that when consumers read negative e-WOM messages before positive e-WOM messages, the negative effects of the negative e-WOM messages can be counterbalanced by the positive effects of the positive e-WOM messages resulting in more favorable attitudes. Study 3 demonstrated that the negative effects of negative e-WOM messages about a brand were diminished when consumers were familiar with the brand. This result extends knowledge about the moderating effects of brand familiarity on traditional WOM to its effects on the ratio of positive to negative e-WOM messages on a single webpage.

In conclusion, this dissertation succeeded in identifying the conditions under which (1) negative e-WOM can have positive effects on consumer product evaluation, (2) positive effects of negative e-WOM can be enhanced, and (3) negative effects of negative e-WOM can be diminished by focusing on various moderators such as product characteristics, review characteristics, and receiver characteristics.
