Abstract
This paper empirically analyzes the effect of the widely used agency model on retail prices of e-books sold in the United Kingdom. Using an unique cross-sectional dataset of e-book prices for a large number of book titles across all major publishing houses, we exploit cross-genre and cross-publisher variation to identify the effect of the agency model on e-book prices. Since the genre information is ambiguous and even missing for some titles in our original dataset, we also apply a Latent Dirichlet Allocation (LDA) approach to determine detailed book genres based on the book’s descriptions. We find that retail prices for e-books sold under the agency model are on average 18% cheaper than book titles sold under the wholesale model. Our results are robust to different regression specifications, an instrumental variable approach, and double machine learning techniques.
