'Corruption - often seen as opportunistic rulebreaking-has norms and codes all its own. They are among the most important, yet least understood, reasons why it is so tenacious. Della Porta and Vannucci bring out the "deep structure" of corruption, challenging the ways we look at it and many of our strategies for reform.' Michael Johnston, Colgate University, USA 'Uncertainty, mutual distrust, and fear are usually things to avoid. Yet, Della Porta and Vannucci show that they are essential for the control of corruption. Interpersonal trust and norms of reciprocity facilitate bribery. Their rich and fascinating book illustrates this argument with a wide variety of examples, ranging from Italy to Illinois to Sub-Saharan Africa.' Susan Rose-Ackerman, Yale Law School, USA ’...a wonderfully researched analysis...The authors have skilfully undertaken innovative and path -breaking research and woven it into a strong analytical narrative...This well researched and thoughtful book is original in its analysis of a complex and elusive set of behaviours that invite more criminological research.’ Australian and New Zealand Journal of Criminology
