“Christina Ewig has written a first-rate book that makes contributions on several different levels. On the one hand, it integrates central political science concerns about the impact of welfare legacies and epistemic communities with a growing literature on gender equality and politics. At the same time, the book explores these issues through a compelling history of Peruvian health policy, focusing especially on the evolution of services shaped in response to the demands of male-dominated unions and then on efforts to restructure the system in the 1990s and early 2000s. Ewig’s analysis is all the more impressive because it is informed by extensive fieldwork that she conducted in Peru over the course of several years. Besides the obvious appeal this book will have for specialists in Peru, it should be of great interest to students of comparative social policy and of the complex politics of gender, intersectionality, and historical legacies.”—Robert Kaufman, Rutgers University
