Ensuring a decent level of worker protection in the globalized economy remains one of the central challenges of economic globalization. This profoundly intricate issue will likely remain unresolved until all its aspects are properly understood. The present volume assembles timely analyses, written by expert scholars and experienced practitioners, of the most pressing legal questions arising in the field. It bridges existing gaps between the different sub-fields of law and surpasses the boundaries of professional and epistemic communities, to foster a more comprehensive understanding of labour standards in international economic law. Most contributions to this volume were inspired by presentations given at the G€ottingen Conference on Labour Standards in International Economic Law, convened on 1–2 October 2015 by the Institute of International and European Law’s Department of International Economic and Environmental Law in G€ottingen. Additional chapters on further important issues were included to round off the compilation. It is a keen pleasure to acknowledge all those who have made this volume possible. First and foremost, I wish to express my sincere gratitude to Peter-Tobias Stoll, whose expertise and unfailing and dedicated support have made both the conference and this volume possible. Special thanks are due to all the authors for their invaluable contributions to this book and to the conference. Furthermore, I wish to thank Mary Footer, Pablo Lazo Grandi, Inmaculada Mart?´nez-Zarzoso, Frank Schorkopf, Friedl Weiss and Ruben Zandvliet for enriching the conference as speakers and chairs. Last but not least, I am grateful to Anna Kozyakova, Mauricio Pacheco, Doris Ruhr, Laura Wanner, Oskar de Wyl and Jia Xu, who served as members of the conference organization team, and to Jasmin Evers, Laura Wanner and Oskar de Wyl for assisting me with the edition of the manuscript.
