Is Online Word of Mouth Higher for New Models or Redesigns? An Investigation of the Automobile Industry

Changing consumer preferences, entry of new competitors with better products, and product improvements by existing competitors make new products a necessary investment for most companies. In addition to the investments in R&D and production of new products, firms also need to invest in advertising to promote them. The growing use of social media by consumers therefore makes online consumer conversations an attractive additional format for firms to promote products at a lower cost. This is particularly so in the automobile industry where advertising costs are very high. Whether consumers discuss a newly introduced product, and help to promote it, however, may depend on how new the product is. This is the question that we investigate in the context of the automobile category. Specifically, we examine whether online consumer conversations are more likely for new models (e.g., Chevy Volt introduced in 2010) or redesigns of existing models (e.g., the redesign of Chevy Impala in 2010). We use data from two online sites where consumers discuss automobiles - consumerreports.org and edmunds.com - for our analysis. Our empirical investigation also accounts for the effects of sales on word of mouth and the simultaneity between sales and word of mouth. Additionally, we also consider the effect of satisfaction on word of mouth and the endogeneity of satisfaction. Our results across two datasets suggest that redesigns stimulate significantly more conversations than new models. Managerial and research implications of the findings are discussed.
