The research was made possible through generous funding from the European Research Council under the EXTORT project (ERC-ADG - Advanced Grant 2019, Grant Agreement ID: 884839). Our home institutions — University College London (UCL), Goldsmiths University of London, the London School of Economics and Political Science (LSE), the University of St Gallen, the University of Oslo, the University of Zurich, Université Paris Nanterre/CNRS, CNRS/EHESS, and the Universidad Mayor de San Andrés (UMSA) — provided not only the institutional support, time, and facilities required to carry out extensive fieldwork, but also the space for the many meetings, workshops, and discussions that are among the greatest pleasures of collaborative scholarly work. We are particularly grateful to institutional support at UCL and our finance and grants manager, Wendy Chandler. Lastly, the countless participants who collaborated by giving their time and information on a sensitive topic during fieldwork, we also extend our deep gratitude.
