Peter John’s How Far to Nudge? delivers a timely assessment of the progress and promise of behavioural economics (BE) as the initial burst of general enthusiasm gives way to a more reflective evaluation. The book provides a comprehensive primer to the uninitiated – John has the ability to convey complex ideas and concepts with great ease and simplicity – but also offers the informed academic or experienced policy practitioner with some interesting insights and ideas on the future direction of behavioural public policy. In the first seven chapters, John assesses the development of the area. Chapter 1 provides a summary of the scope of the book. Chapter 2, ‘Behavioural Public Problems’, comprehensively describes the areas that cover behavioural policy; for example, our resistance to behaviours that we know are beneficial; habits – the behaviours that we barely recognise; our reactance to authority; and collective behaviours. This chapter finishes with an interesting discussion on the impact of poverty and blame attribution. John, in an example of his clear style, tells us that human behaviour, as a crucial aspect of achieving desired policy outcomes, should be more than a truism. The behavioural argument has to ‘take the causal form that certain behavioural traits and biases detrimentally affect the policy outcomes in ways that are systematic, knowable and fixable’. Chapters 3, 4 and 5 provide an easily digestible summary of the development of inquiry into human behaviour. Chapter 3 outlines the reasons for the pre-eminence of the rational choice model and subsequent criticisms of the model. John then gives us a solid history of BE up to the publication of the Nudge book that brought BE into the public consciousness. He outlines ‘nudge’ in Chapter 4. Chapter 5

推多远？评估行为公共政策

彼得约翰的《微调有多远？及时评估行为经济学 (BE) 的进展和前景，因为最初爆发的普遍热情让位于更具反思性的评估。这本书为初学者提供了全面的入门读物——约翰能够轻松简单地传达复杂的思想和概念——但也为知识渊博的学术界或经验丰富的政策从业者提供了一些关于行为公共政策未来方向的有趣见解和想法. 在前七章中，约翰评估了该地区的发展。第 1 章概述了本书的范围。第 2 章，“行为公共问题”，全面描述了行为政策的领域；例如，我们对已知有益行为的抵制；习惯——我们几乎不认识的行为；我们对权威的反应；和集体行为。本章结束时对贫困的影响和责备归因进行了有趣的讨论。约翰以他清晰风格的例子告诉我们，作为实现预期政策结果的一个关键方面，人类行为不应该是老生常谈。行为论点必须“采取因果形式，即某些行为特征和偏见以系统、可知和可修复的方式对政策结果产生不利影响”。第 3、4 和 5 章对人类行为调查的发展进行了易于理解的总结。第 3 章概述了理性选择模型优越的原因以及随后对该模型的批评。然后，约翰为我们讲述了 BE 的坚实历史，直至将 BE 带入公众意识的 Nudge 书的出版。他在第 4 章概述了“轻推”。第 5 章
