'At a time when the anti-corruption movement is in need of critical self-assessment, Rothstein and Varraich offer an important analysis. We know we do not want corruption - but what do we want? Can we, and should we, disentangle corruption from the many other related difficulties undermining the well-being of people and societies in many parts of the world? How do we know where corruption is worst, and whether our reforms are helping, hurting, or having any effects at all? Scholars and policy makers alike will find the insights offered by Rothstein and Varraich essential as their anti-corruption work enters new phases.' Michael Johnston, Colgate University, New York
