'This is an interesting, comprehensive and excellent examination of the behavioural aspects of tax compliance and evasion based on insights from social and cognitive psychology, behavioural economics, and game theory. Kirchler's book considers the role of economic incentives in tax compliance, but he also argues that factors such as moral considerations, fairness concerns, and the citizens' trust in the state play a crucial role. His broad approach makes the book interesting for both tax authorities and social scientists alike.' Ernst Fehr, Director of the Institute for Empirical Research in Economics, University of Zürich
