讲座摘要：
The $300+ billion digital content industries, encompassing e-books, movies, music, gaming, and many others, commonly leverage freemium pricing, offering initial contents, such as the first few chapters of a book or first few minutes of a song or video for free, hoping to monetize the later content with a premium. Determining the optimal amount of free content, or conversely the optimal charging point (such as charging at Chapter 40), is challenging, since offering scant free content risks customer churn, whereas offering a lavish amount diminishes profit. More importantly, freemium pricing for digital content, unlike for consumer packaged goods (sampling literature) or technology products (versioning literature), is closely related to content dynamics. For instance, charging at a story’s emotional high or critical turning point would potentially lead to stronger customer willingness-to-pay.
Collaborating with a leading e-book platform, we determine the optimal charging points for e-books via a large-scale randomized field experiment involving 1.3 million customers. The resulting remarkable 50% lift in revenues per product from optimizing the charging point would translate into a $100+ million annual revenue gain for the entire platform. We further propose innovative text analytic methods to determine the landmarks of content dynamics of each product, such as the sentiment or emotion culminations. The model-free evidence and statistical analyses reveal that the identified optimal charging points tend to occur right after the second culmination. Two mechanisms underlie this finding: the moment-to-moment synchrony between a book’s content and consumers’ comments, as well as bulk (multi-chapter) instead of single-chapter purchase, commonly peak right after the second culmination. Finally, a personalized pricing design showcases the vast commercial power of leveraging the AI-Machine Learning driven optimization and personalization to automate the conventionally intuition-laden and labor-intensive pricing for massive numbers of heterogeneous digital content products and customers.
