From acclaimed economists George Akerlof and Robert Shiller, the case for why government is needed to restore confidence in the economy The global financial crisis has made it painfully clear that powerful psychological forces are imperiling the wealth of nations today. From blind faith in ever-rising housing prices to plummeting confidence in capital markets, "animal spirits" are driving financial events worldwide. In this book, acclaimed economists George Akerlof and Robert Shiller challenge the economic wisdom that got us into this mess, and put forward a bold new vision that will transform economics and restore prosperity. Akerlof and Shiller reassert the necessity of an active government role in economic policymaking by recovering the idea of animal spirits, a term John Maynard Keynes used to describe the gloom and despondence that led to the Great Depression and the changing psychology that accompanied recovery. Like Keynes, Akerlof and Shiller know that managing these animal spirits requires the steady hand of government―simply allowing markets to work won't do it. In rebuilding the case for a more robust, behaviorally informed Keynesianism, they detail the most pervasive effects of animal spirits in contemporary economic life―such as confidence, fear, bad faith, corruption, a concern for fairness, and the stories we tell ourselves about our economic fortunes―and show how Reaganomics, Thatcherism, and the rational expectations revolution failed to account for them. Animal Spirits offers a road map for reversing the financial misfortunes besetting us today. Read it and learn how leaders can channel animal spirits―the powerful forces of human psychology that are afoot in the world economy today.

Akerlof and Shiller argue that markets harm as well as help us. As long as there is profit to be made, sellers will systematically exploit our psychological weaknesses and our ignorance through manipulation and deception. Based on the intuitive idea that markets both give and take away, they show how phishing affects everyone, in almost every walk of life. We spend our money up to the limit, and then worry about how to pay the next month's bills. The financial system soars, then crashes. In exploring the role of manipulation and deception, the authors explain a paradox: why, at a time when we are better off than ever before in history, all too many of us are leading lives of quiet desperation.

In 1995, economist Rachel Kranton wrote future Nobel Prize-winner George Akerlof a letter insisting that his most recent paper was wrong. Identity, she argued, was the missing element that would help to explain why people - facing the same economic circumstances - would make different choices. This was the beginning of a fourteen-year collaboration - and of Identity Economics. Identity economics is a new way to understand people's decisions - at work, at school, and at home. With it, we can better appreciate why incentives like stock options work or don't; why some schools succeed and others don't; why some cities and towns don't invest in their futures - and much, much more. "Identity Economics" bridges a critical gap in the social sciences. It brings identity and norms to economics. People's notions of what is proper, and what is forbidden, and for whom, are fundamental to how hard they work, and how they learn, spend, and save. Thus people's identity - their conception of who they are, and of who they choose to be - may be the most important factor affecting their economic lives. And the limits placed by society on people's identity can also be crucial determinants of their economic well-being.

These essays explore what happens when a skilful economist makes unconventional assumptions. Economic theory has traditionally relied upon a tacit and 'classical' set of assumptions that have gradually acquired a life of their own in defining how economists write and how they justify economic models. Similarly, these assumptions have acquired an autonomous character: they guide the way economists think about the world. In consequence, consideration of alternative assumptions has become taboo. These essays are substantively and stylistically novel because they break these taboos and bring new assumptions into economic theory. The papers apply this adventurous approach to a wide range of issues - from insurance markets and trade in underdeveloped countries to unemployment and discrimination. Some of the essays derive the implications for economic markets of costly asymmetric information. Others explore the findings of other social sciences such as anthropology, psychology and sociology.
