'Düppe's book is undoubtedly a labor of love, based as it is on exhaustive multi-archival research supplemented by extensive interviews conducted with relatives and colleagues of the men he covers. The author has also mastered a very sizable literature on the GDR and the history of economic thought, including the published writings of the economists in question. Indeed, the book is the most thorough analysis to date on this subject and is likely to become definitive ... It is a book about a generation of men who formed the core of the GDR's intelligentsia, revealing how the SED manufactured consent and generated stability, two areas where it undoubtedly excelled.'
