‘This tour de force provides a very sophisticated presentation and discussion of the wide variety of methods and approaches available for comparative policy analysis. Taking different approaches seriously, the book unpacks the epistemological and methodological foundations of different approaches, showing how and when they can be used. Building on a nuanced discussion of what it means to compare in policy analysis and the legacy of Mill’s methods, the book introduces both classic and recent comparative methods, ranging from experimental approaches to paired comparisons. The text is admirably accessible despite the difficulty of some of the philosophical and methodological concepts discussed. The book also provides numerous recent examples that provide a great resource for scholars searching for exemplars of good applications of different methods in the field. What I really appreciated is that the authors do not suggest that there is one “best” approach, but instead all have comparative strengths and weaknesses that need to be taken seriously. Taken as a whole, the book will stand as an invaluable resource for any scholar interested in explaining and understanding public policies using comparative methods.’
