Abstract
Online buzz reflects the perceived quality of products in a positive, negative, or neutral way. We have limited understanding of how customers’ quality perceptions, often referred to as e-sentiment, affect the movement of prices. In this paper, we examine the effect of e-sentiment on the daily price fluctuations of MP3 players by using daily buzz information collected from diverse online documents. Econometric panel data modeling reveals that e-sentiment is a leading indicator of price fluctuations. Furthermore, we find the effect is moderated by the brand’s market position: the leading (challenger) brand’s price responds more strongly to negative (positive) online buzz. In other words, negative buzz has a greater adverse effect on leading brands, whereas positive buzz has a greater beneficial effect on challenger brands. These findings establish the relevance of e-sentiment information to online price movements and suggest that managers should frequently monitor the online buzz surrounding their products, especially as it relates to their relative perceived quality.

Notes
Subjective quality assessment is often called ‘quality perceptions,’ ‘perceived value,’ or ‘perceived quality’ in the marketing literature. Quality perceptions consist of three components: (1) abstract dimensions of intrinsic attributes (e.g., safety, durability), (2) perceived monetary price, and 3) reputation formed through advertising and brand name [61].
Accordingly, researchers often rely on a proxy, such as sales rank. Even though sales rank information is known to approximate actual sales to some extent (e.g., [32]), it is still not a perfect measure.
To help ‘confused’ customers, the CNET MP3 Player Buying Guide suggests “10 Key MP3 Play Features” in addition to basic attributes such as sound quality and design (http://reviews.cnet.com/4520-7964_7-5134106.html).
Note that T = 61 for all products except the iPod Mini, which was not available at Amazon.com for the first seven days (June 2–8). Accordingly, our database contains 54 observations for the iPod Mini.
The ADF and PP panel unit root tests can be used to check whether a focal variable is stationary. If stationary, we can perform a conventional regression analysis. If non-stationary, we can make the variable stationary by differencing. For more details, see Enders [28].
Note that the iPod Mini was replaced by the iPod Nano in 2006. During the data collection period in 2007, one to two e-vendors carried the iPod Mini at a price approximately 60 % cheaper than the original price.
For a specification with K = 2 and above, we found that either the estimation does not converge or the coefficients of additional lag terms are statistically insignificant. Accordingly, we conclude that K = 1 is the best specification, even aside from the parsimony issue.
Price elasticity reported in the table is calculated as the average of each individual product’s price elasticity, which is calculated by multiplying the estimated coefficient of the e-sentiment variable by the average value of the variable divided by the average value of price in the sample.
