Bestselling author Cass R. Sunstein reveals the appeal and the danger of conformity We live in an era of tribalism, polarization, and intense social division-separating people along lines of religion, political conviction, race, ethnicity, and sometimes gender. How did this happen? In Conformity, Cass R. Sunstein argues that the key to making sense of living in this fractured world lies in understanding the idea of conformity-what it is and how it works-as well as the countervailing force of dissent. An understanding of conformity sheds new light on many issues confronting us today: the role of social media, the rise of fake news, the growth of authoritarianism, the success of Donald Trump, the functions of free speech, debates over immigration and the Supreme Court, and much more. Lacking information of our own and seeking the good opinion of others, we often follow the crowd, but Sunstein shows that when individuals suppress their own instincts about what is true and what is right, it can lead to significant social harm. While dissenters tend to be seen as selfish individualists, dissent is actually an important means of correcting the natural human tendency toward conformity and has enormous social benefits in reducing extremism, encouraging critical thinking, and protecting freedom itself. Sunstein concludes that while much of the time it is in the individual's interest to follow the crowd, it is in the social interest for individuals to say and do what they think is best. A well-functioning democracy depends on it.

From New York Times bestselling author and economics columnist Robert Frank, bold new ideas for creating environments that promise a brighter future Psychologists have long understood that social environments profoundly shape our behavior, sometimes for the better, often for the worse. But social influence is a two-way street-our environments are themselves products of our behavior. Under the Influence explains how to unlock the latent power of social context. It reveals how our environments encourage smoking, bullying, tax cheating, sexual predation, problem drinking, and wasteful energy use. We are building bigger houses, driving heavier cars, and engaging in a host of other activities that threaten the planet-mainly because that's what friends and neighbors do. In the wake of the hottest years on record, only robust measures to curb greenhouse gases promise relief from more frequent and intense storms, droughts, flooding, wildfires, and famines. Robert Frank describes how the strongest predictor of our willingness to support climate-friendly policies, install solar panels, or buy an electric car is the number of people we know who have already done so. In the face of stakes that could not be higher, the book explains how we could redirect trillions of dollars annually in support of carbon-free energy sources, all without requiring painful sacrifices from anyone. Most of us would agree that we need to take responsibility for our own choices, but with more supportive social environments, each of us is more likely to make choices that benefit everyone. Under the Influence shows how.

From New York Times bestselling author and economics columnist Robert Frank, a compelling book that explains why the rich underestimate the importance of luck in their success, why that hurts everyone, and what we can do about it How important is luck in economic success? No question more reliably divides conservatives from liberals. As conservatives correctly observe, people who amass great fortunes are almost always talented and hardworking. But liberals are also correct to note that countless others have those same qualities yet never earn much. In recent years, social scientists have discovered that chance plays a much larger role in important life outcomes than most people imagine. In Success and Luck, bestselling author and New York Times economics columnist Robert Frank explores the surprising implications of those findings to show why the rich underestimate the importance of luck in success--and why that hurts everyone, even the wealthy. Frank describes how, in a world increasingly dominated by winner-take-all markets, chance opportunities and trivial initial advantages often translate into much larger ones--and enormous income differences--over time; how false beliefs about luck persist, despite compelling evidence against them; and how myths about personal success and luck shape individual and political choices in harmful ways. But, Frank argues, we could decrease the inequality driven by sheer luck by adopting simple, unintrusive policies that would free up trillions of dollars each year--more than enough to fix our crumbling infrastructure, expand healthcare coverage, fight global warming, and reduce poverty, all without requiring painful sacrifices from anyone. If this sounds implausible, you'll be surprised to discover that the solution requires only a few, noncontroversial steps. Compellingly readable, Success and Luck shows how a more accurate understanding of the role of chance in life could lead to better, richer, and fairer economies and societies.

The idea rests on a simple paradox, namely, that in many situations the conscious pursuit of self-interest is incompatible with its attainment. We are all comfortable with the notion that someone who strives to be spontaneous can never succeed. So too, on brief reflection, will it become apparent that someone who always pursues self-interest is doomed to fail.

Financial disasters--and stories of the greedy bankers who precipitated them--seem to underscore the idea that self-interest will always trump concerns for the greater good. Indeed, this idea is supported by the prevailing theories in both economics and evolutionary biology. But is it valid?

In "What Price the Moral High Ground?," economist and social critic Robert Frank challenges the notion that doing well is accomplished only at the expense of doing good. Frank explores exciting new work in economics, psychology, and biology to argue that honest individuals often succeed, even in highly competitive environments, because their commitment to principle makes them more attractive as trading partners.

Drawing on research he has conducted and published over the past decade, Frank challenges the familiar homo economicus stereotype by describing how people create bonds that sustain cooperation in one-shot prisoner's dilemmas. He goes on to describe how people often choose modestly paid positions in the public and nonprofit sectors over comparable, higher-paying jobs in the for-profit sector; how studying economics appears to inhibit cooperation; how social norms often deter opportunistic behavior; how a given charitable organization manages to appeal to donors with seemingly incompatible motives; how concerns about status and fairness affect salaries in organizations; and how socially responsible firms often prosper despite the higher costs associated with their business practices.

Frank's arguments have important implications for the conduct of leaders in private as well as public life. Tossing aside the model of the self-interested homo economicus, Frank provides a tool for understanding how to better structure organizations, public policies, and even our own lives.

Who was the greater economist--Adam Smith or Charles Darwin? The question seems absurd. Darwin, after all, was a naturalist, not an economist. But Robert Frank, "New York Times" economics columnist and best-selling author of "The Economic Naturalist," predicts that within the next century Darwin will unseat Smith as the intellectual founder of economics. The reason, Frank argues, is that Darwin's understanding of competition describes economic reality far more accurately than Smith's. And the consequences of this fact are profound. Indeed, the failure to recognize that we live in Darwin's world rather than Smith's is putting us all at risk by preventing us from seeing that competition alone will not solve our problems.

Smith's theory of the invisible hand, which says that competition channels self-interest for the common good, is probably the most widely cited argument today in favor of unbridled competition--and against regulation, taxation, and even government itself. But what if Smith's idea was almost an exception to the general rule of competition? That's what Frank argues, resting his case on Darwin's insight that individual and group interests often diverge sharply. Far from creating a perfect world, economic competition often leads to "arms races," encouraging behaviors that not only cause enormous harm to the group but also provide no lasting advantages for individuals, since any gains tend to be relative and mutually offsetting.

The good news is that we have the ability to tame the Darwin economy. The best solution is not to prohibit harmful behaviors but to tax them. By doing so, we could make the economic pie larger, eliminate government debt, and provide better public services, all without requiring painful sacrifices from anyone. That's a bold claim, Frank concedes, but it follows directly from logic and evidence that most people already accept.

In a new afterword, Frank further explores how the themes of inequality and competition are driving today's public debate on how much government we need.

The turn of the twenty-first century witnessed a spectacular rise in gross consumption. With the super-rich setting the pace, everyone spent furiously in a desperate attempt to keep up. As cars and houses grew larger and more expensive, the costs were enormous--not only monetarily but also socially. Consumers spent more time at work and less time with their family and friends; they saved less money and borrowed more.

In this book, Robert Frank presents the first comprehensive and accessible account of these financial choices. Frank uses scientific evidence to demonstrate how these spending patterns have not made us happier or healthier. "Luxury Fever" offers an exit from the rat race, suggesting ways to curb the culture of excess and restore true value to our lives.

Have you ever wondered why there is a light in your fridge but not in your freezer? Or why 24-hour shops bother having locks on their doors? Or why soft drink cans are cylindrical, but milk cartons are square? The answer is simple: economics. For years, economist Robert Frank has been encouraging his students to ask questions about the conundrums and strange occurrences they encounter in everyday life and to try to explain them using economics. Now in this bestselling book, he shares the most intriguing - and bizarre - questions and the economic principles that answer them to reveal why many of the most puzzling parts of everyday life actually make perfect (economic) sense.

The Economic Naturalist is back with a whole batch of intriguing new questions and answers, drawn from his New York Times columns, that reveal how we really behave when confronted with economic choices. Do tax cuts for business owners really stimulate employment? Why shouldn't we just leave everything to the market? And why do we all save so little? Discover the answers to these and many more questions. With his trademark plain-speaking wit and insight, Robert Frank shows through dozens of examples how our personal choices about everything from paying for food and housing to large-scale policy decisions about taxation and the regulation of markets all boil down to the same simple economic principles, often resulting in the same wasteful mistakes. He shows that while our desires may be boundless, the resources necessary to satisfy them remain limited and argues that choices are always best made pragmatically - by carefully weighing the costs and benefits of competing options. This is a fascinating, entertaining and revealing collection full of insights that have more bearing than ever on our bank balances and our personal happiness.

In recent years, innovative texts in mathematics, science, foreign languages, and other fields have achieved dramatic pedagogical gains by abandoning the traditional encyclopedic approach in favor of attempting to teach a short list of core principles in depth. Two well-respected writers and researchers, Bob Frank and Ben Bernanke, have shown that the less-is-more approach affords similar gains in introductory economics. Although recent editions of a few other texts have paid lip service to this new approach, Frank/Bernanke is by far the best thought out and best executed principles text in this mold. Avoiding excessive reliance on formal mathematical derivations, it presents concepts intuitively through examples drawn from familiar contexts. The authors introduce a well-articulated short list of core principles and reinforcing them by illustrating and applying each in numerous contexts. Students are periodically asked to apply these principles to answer related questions, exercises, and problems.. .

The text also encourages students to become "Economic Naturalists," people who employ basic economic principles to understand and explain what they observe in the world around them. An economic naturalist understands, for example, that infant safety seats are required in cars but not in airplanes because the marginal cost of space to accommodate these seats is typically zero in cars but often hundreds of dollars in airplanes. Such examples engage student interest while teaching them to see each feature of their economic landscape as the reflection of an implicit or explicit cost-benefit calculation. . .

The Second Edition of Frank/Bernanke follows the successful First Edition withseveral pedagogical improvements. Based on reviewer feedback, this edition offers (1) even more streamlined coverage of the cost-benefit approach in the introductory chapter; (2) exercises that are more closely tied to the examples; (3) expanded narrative explanations of important principles, making them more accessible to average students; and (4) expanded coverage of several key topics [see below]. The result is a revision that is motivating to students, an effective text for teaching, and an exciting first course in Economics..
