Apart from a brief postscript to one of the chapters and a few remarks in the preface, George Akerlof and Robert Shiller’s Animal Spirits was written before the current crisis. Yet, based on research undertaken over many years, it can be read as prefiguring the current disillusionment with economics. The trouble with prevailing theories, in Akerlof and Shiller’s view, is that they assume human beings are more rational than they actually are. ‘This book, which draws on an emerging field called behavioural economics, describes how the economy really works,’ they claim. ‘It accounts for how it works when people really are human, that is, possessed of all-too-human animal spirits.’
