Abstract: While the literature has reached a consensus on the awareness effect of online word-of-mouth (eWOM), this paper studies its persuasive effect-specifically, dimension-specific sentiment effects on product sales. We examine the sentiment information in eWOM along different product dimensions and reveal different persuasive effects on consumers' purchase decisions based on consumers' sentiment preference, which is defined as the relative importance that consumers place on various dimension-specific sentiments. We use an aspect-level sentiment analysis to derive dimension-specific sentiment and PVAR (panel vector auto-regression) models, and estimate their effects on product sales using a movie panel dataset. The findings show that three dimension-specific sentiments (star, genre, and plot) are positively related to movie sales. Regarding consumers' sentiment preferences, we find a positive relationship to movie sales that is stronger for plot sentiment, relative to star sentiment for low-budget movies. For high-budget movies, we find a positive relationship to movie sales that is stronger for star sentiment, relative to plot or genre sentiment. Collapse

Abstract: Digital distribution channels raise many new challenges for managers in the media industry. This is particularly true for movie studios where high-value content can be stolen and released through illegitimate digital channels, even prior to the release of the movie in legal channels. In response to this potential threat, movie studios have spent millions of dollars to protect their content from unauthorized distribution throughout the lifecycle of films. They have focused their efforts on the pre-release period under the assumption that pre-release piracy could be particularly harmful for a movie’s success. However, surprisingly, there has been little rigorous research to analyze whether, and how much, pre-release movie piracy diminishes legitimate sales. In this paper, we analyze this question using data collected from a unique Internet file-sharing site. We find that, on average, pre-release piracy causes a 19.1% decrease in revenue compared to piracy that occurs post-release. Our study contributes to the growing literature on piracy and digital media consumption by presenting evidence of the impact of Internet-based movie piracy on sales and by analyzing pre-release piracy, a setting that is distinct from much of the existing literature.
