Book excerpt: The effectiveness and capacity of survival of democratic regimes has been recently and widely questioned in the public and political debate. Both democratic institutions and political actors are increasingly confronted with rapid economic and societal transformations that, at least according to some observers and commentators, they not seem to be ready or equipped to manage effectively. This book evaluates and challenges recent scholarly literature on the quality of democracy. It provides a critical assessment of the current state of the studies on the subject, identifying the key questions and discussing open issues, alternative approaches, problems and future developments. Bringing together some of the most prominent and distinguished scholars who have developed and discussed the topic of the quality of democracy during the last decade, it deals with a highly relevant topic in political science and extremely sensitive subject for our democratic societies. This text will be of key interest to scholars of democracy and democratization and more broadly to comparative politics, electoral studies, political theory, power and comparative political institutions.
