Why the free-market system encourages so much trickery even as it creates so much goodEver since Adam Smith, the central teaching of economics has been that free markets provide us with material well-being, as if by an invisible hand. In Phishing for Phools, Nobel Prize-winning economists George Akerlof and Robert Shiller deliver a fundamental challenge to this insight, arguing 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. Rather than being essentially benign and always creating the greater good, markets are inherently filled with tricks and traps and will "e;phish"e; us as "e;phools."e;Phishing for Phools therefore strikes a radically new direction in economics, based on the intuitive idea that markets both give and take away. Akerlof and Shiller bring this idea to life through dozens of stories that 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. We are attracted, more than we know, by advertising. Our political system is distorted by money. We pay too much for gym memberships, cars, houses, and credit cards. Drug companies ingeniously market pharmaceuticals that do us little good, and sometimes are downright dangerous.Phishing for Phools explores the central role of manipulation and deception in fascinating detail in each of these areas and many more. It thereby explains 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. At the same time, the book tells stories of individuals who have stood against economic trickery-and how it can be reduced through greater knowledge, reform, and regulation.

Identity Economics provides an important and compelling new way to understand human behavior, revealing how our identities--and not just economic incentives--influence our decisions. 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. The authors explain how our conception of who we are and who we want to be may shape our economic lives more than any other factor, affecting how hard we work, and how we learn, spend, and save. 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.

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, "e;animal spirits"e; 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. In a new preface, they describe why our economic troubles may linger for some time--unless we are prepared to take further, decisive action.

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. These essays explore what happens when a skilful economist makes unconventional assumptions.
