Abstract

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.

消除电子书市场的数字版权管理

我们研究了从电子书设备中移除数字版权管理(DRM)的影响。基于消费者效用最大化问题，我们推导了一个贝叶斯层次logit模型，并利用基于选择的调查数据对模型进行了估计。然后，我们模拟了取消DRM时的反事实市场结果;平均而言，在其他一切保持不变的情况下，消费者剩余会显著增加。然而，当我们重新调整电子书设备的价格时，消费者剩余的增长就会减少。此外，如果内容供应受到负面冲击，那么在DRM移除后，消费者剩余实际上可能会减少。
