First and foremost, I am indebted to Kim Lane Scheppele, my doctoral advisor and mentor. I am grateful for having had the possibility to learn from her. Alison Brysk and Henri Vogt pre-examined my dissertation, on which this book builds, and Professor Beth Simmons acted as the opponent at my unforgettable public defense in 2014. I am thankful for their helpful comments. I also feel privileged for having had the opportunity to gain from the advice of John Ikenberry, Andrew Moravcsik, and Robert Keohane. Timo Kivim?ki discussed numerous drafts of this project and has been encouraging over the years. Tero Erkkil? pushed me to revise the dissertation into a book and I am very thankful for that.
