This symposium, held jointly by the NYU Law Review, the Guarini Institute for Global Legal Studies and the Institute for International Law and Justice at NYU School of Law on 9 November 2018, examined how law does, should, or can affect data ownership, concentration, and control in a global digital economy. The symposium took a conceptual approach to the law of data by confronting emerging issues in the global digital economy through analyses grounded in foundational legal concepts such as contracting, torts, property, trusts/fiduciary law, and more specialized areas of international economic law such as antitrust, tax, and trade law. The symposium was not centrally focused on detailed analysis of intellectual property law or information privacy law, which already occupy a core place in scholarship on data law, although these areas of law may certainly figure where relevant to concepts and regulatory and structural arguments. Commentators with particular additional expertise enriched the symposium. Together with the Law Review editors, our intention for organizing this symposium was to make a significant contribution to the foundations of an important and fast-developing field.
