Property rights of personal data have been advocated for some time. From the perspective of economics of law some argued that they could lower transaction costs for contracts involving personal data. This may be the case, but new transaction costs are introduced by propertization and the issue has not been settled. In this paper, I focus on a different and potentially more important aspect. In the actual situation, data collectors externalize costs and internalize benefits. An ownership regime that enables every (...) citizen to hold a personal data account, like a bank account, and that gives people ownership rights over secondary use of personal data could correct these misallocations. I hope to shed new light on the normative implications of the issue by offering normative justifications for property rights of personal data (Sections 2–4). Secondly, I present fundamental goals and building blocks of a property regime of personal data (Section 5) and, thirdly, I illustrate how income from personal data ownership could for instance contribute to financing pensions under proper regulation (Section 6).
