Abstract
Digital goods are increasingly produced by average individuals in a serialized fashion. However, it is unclear whether users engage in herding in the consumption and purchase of such digital goods and what the moderators of the herding effect are. Thus, we propose a simultaneous equations model based on herding theory to theoretically examine users’ potential herding behavior through two competing effects: the private signal effect and the sequential actions effect, which refer to the impact of the private signals and observed sequential actions of others on user quality inference and herding, respectively. The model is implemented in a hierarchical Bayes framework, and it is estimated using data from the top Chinese literature site. The empirical results suggest that users engage in rational herding in both digital book consumption and purchase on the focal site and that the herding bias is surprisingly stronger for purchasing. Product features significantly mitigate the herding bias, while the reputation of the producer and competition exacerbate the herding effect. The impact of this rational herding is also quantified. This study offers new insights and important theoretical and managerial implications for marketing researchers, amateur producers, marketing managers, and publishers.

Notes
Social influence or contagion refers to the spread of ideas, attitudes, or behavior patterns in a group through imitation and conformity (Colman 2014). Imitation is an advanced behavior whereby an individual observes and replicates another’s behavior. Therefore, herding is one specific type of informational social influence or imitation where the two conditions (the uncertainty condition and the sequential action condition) must be satisfied. Social contagion and imitation do not necessarily lead to herding.
We used two popular text analyzers for Chinese characters on some book chapters from the site—the Chinese parser developed by the Stanford Natural Language Processing Group (http://nlp.stanford.edu/software/lex-parser.html) and yoshikoder software developed by Will Lowe at Harvard’s Weatherhead Center for International Affairs (http://yoshikoder.sourceforge.net/). Unfortunately, we found that the accuracy of these text analysis tools is low and unreliable, and this textual analysis was overwhelmingly time-consuming.
