Eliminating digital rights management from the E-book market

We examine the impact of removing Digital Rights Management (DRM) from electronic book devices. We derive a Bayesian hierarchical logit model based on the consumer’s utility maximization problem and estimate the model using data from a choice-based survey. We then simulate the counterfactual market outcomes when DRM is removed; on average, the consumer surplus increases nontrivially holding everything else constant. However, the gain in consumer surplus is diminished when we re-calibrate e-book device prices. Further, if there is a negative shock to content supply, then the consumer surplus could in fact decrease after DRM removal.
