A firm dominant in its market enters a data-rich secondary market and engages in predatory pricing and privacy-policy tying. We define the latter as conditioning service provision to the subscription of a privacy-policy that allows bundling of user data across all sources. Acquiring data from the secondary market confers an advantage in the data-intensive primary market that shields the dominant firm from entry, thus harming consumers. We discuss potential remedies, including data unbundling and portability.}", issn = {0013-0133}, doi = {10.1093/ej/uead090}, url = {https://doi.org/10.1093/ej/uead090}, eprint = {https://academic.oup.com/ej/advance-article-pdf/doi/10.1093/ej/uead090/52727293/uead090.pdf}, }
