报告摘要：

We consider a multi-product monopolist who sells her products sequentially to a buyer with privately known valuations. Using big data, the monopolist perfectly learns the intertemporal correlations of the buyer's valuations. Despite her perfect learning, perfect price discrimination is generally unattainable--even under full commitment, because of an informational externality between the consumer's initial valuation and the correlation structure. This complementarity implies that, despite the seller's perfect knowledge of correlations, the buyer's private information about his initial valuation yields him information rents also for his later consumption. Upward distortions are a robust feature of the resulting monopolistic distortions and their presence are non-monotonic in the seller's data-mining abilities.
