Winner of the Nobel Prize in Economics Get ready to change the way you think about economics. Nobel laureate Richard H. Thaler has spent his career studying the radical notion that the central agents in the economy are humans—predictable, error-prone individuals. Misbehaving is his arresting, frequently hilarious account of the struggle to bring an academic discipline back down to earth—and change the way we think about economics, ourselves, and our world. Traditional economics assumes rational actors. Early in his research, Thaler realized these Spock-like automatons were nothing like real people. Whether buying a clock radio, selling basketball tickets, or applying for a mortgage, we all succumb to biases and make decisions that deviate from the standards of rationality assumed by economists. In other words, we misbehave. More importantly, our misbehavior has serious consequences. Dismissed at first by economists as an amusing sideshow, the study of human miscalculations and their effects on markets now drives efforts to make better decisions in our lives, our businesses, and our governments. Coupling recent discoveries in human psychology with a practical understanding of incentives and market behavior, Thaler enlightens readers about how to make smarter decisions in an increasingly mystifying world. He reveals how behavioral economic analysis opens up new ways to look at everything from household finance to assigning faculty offices in a new building, to TV game shows, the NFL draft, and businesses like Uber. Laced with antic stories of Thaler’s spirited battles with the bastions of traditional economic thinking, Misbehaving is a singular look into profound human foibles. When economics meets psychology, the implications for individuals, managers, and policy makers are both profound and entertaining.

Named one of Financial Times’s Best Books of 2025, that bestselling author Tim Hartford called "fun" and "nerdy in the best way" Nobel Prize winner Richard H. Thaler and rising star economist Alex O. Imas explore the past, present, and cutting-edge future in behavioral economics in The Winner’s Curse. Why do people cooperate with one another when they have no obvious motivation to do so? Why do we hold on to possessions of little value? And why is the winner of an auction so often disappointed? Over thirty years ago, Richard H. Thaler introduced readers to behavioral economics in his seminal Anomalies column, written with collaborators including Daniel Kahneman and Amos Tversky. These provocative articles challenged the fundamental idea at the heart of economics that people are selfish, rational optimizers, and provided the foundation for what became behavioral economics. That was then. Now, three decades later, Thaler has teamed up with economist Alex O. Imas to write a new book with an original and creative format. Each chapter starts with an original Anomaly, retaining the spirit of its time stamp. Then, shifting to the present, the authors provide updates to each, asking how the original findings have held up and how the field has evolved since then. It turns out that the original findings not only hold up well, but they show up almost everywhere. Anomalies pop up in people’s decisions to save for retirement and how they carry outstanding credit card debt. Even experts fail to optimize. The key concept of loss aversion explains missed putts by PGA pros and the selection of which stocks to sell by portfolio managers. In this era of meme stocks and Dogecoin, it is hard to defend the view that financial markets are highly efficient. The good news, however, is that the anomalies have gotten funnier. With both readability and rigor, The Winner’s Curse is for anyone, from those with a cursory understanding of economics to fellow economists. Each chapter provides a key insight into human behavior so readers learn how to better understand the choices made by their friends, colleagues, and customers, and they might just become better at making decisions themselves. Only recommended for humans.

Standard economics theory is built on the assumption that human beings act rationally in their own self interest. But if rationality is such a reliable factor, why do economic models so often fail to predict market behavior accurately? According to Richard Thaler, the shortcomings of the standard approach arise from its failure to take into account systematic mental biases that color all human judgments and decisions.

An updated and refreshed edition of the groundbreaking book that shows how people can be nudged toward decisions that will improve their lives "If you''ve read Nudge and think you fully grasp the concept and its uses, you are mistaken. The new edition significantly deepened my understanding of what nudges are and how they can be employed. It truly is a must-read."―Robert Cialdini, New York Times bestselling author of Influence "Few books can be said to have changed the world, but Nudge did. The Final Edition is marvelous: funny, useful, and wise."―Daniel Kahneman, #1 New York Times bestselling author of Thinking, Fast and Slow Since the original publication of Nudge more than a decade ago, the word "nudge" has entered the vocabulary of businesspeople, policymakers, engaged citizens, and consumers everywhere. The book has given rise to more than 200 "nudge units" in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful "choice architecture"--a concept the authors invented--to help us make better decisions for ourselves, our families, and our society. Now, the authors have rewritten the book from cover to cover, making use of their experiences in and out of government over the past dozen years as well as the explosion of new research in numerous academic disciplines. It offers a wealth of new insights, for both its avowed fans and newcomers to the field, about a wide variety of issues that we face in our daily lives--COVID-19, health, personal finance, retirement savings, credit card debt, home mortgages, medical care, organ donation, climate change, and "sludge" (paperwork and other nuisances that we don''t want and keep us from getting what we do want)--all while honoring one of the cardinal rules of nudging: make it fun!

A collection of 21 recent articles that illustrate the power of a new approach to finance, one which as editor Thaler puts it, "entertains the possibility that some of the agents in the economy behave less than fully rationally some of the time." These papers illustrate how specific departures from fully rational decisionmaking by individual market agents can provide explanations of otherwise puzzling market phenomena.

Has the Nudge Unit Given you a Gentle Push in the Right Direction? Adding just one sentence to a tax reminder brought in millions in extra revenue, Prompting people to become organ donors while paying for their car tax added an extra 100/000 donors to the register, Refocusing the questions asked at the job centre helped an extra 10% of people off benefits and back to work.

This paper examines the proposition that fluctuations in discounts on closed end funds are driven by changes in individual investor sentiment toward closed end funds and other securities. The theory implies that discounts on various funds must move together, that new funds get started when seasoned funds sell at a premium or a small discount, and that discounts on the funds fluctuate together with prices of securities affected by the same investor sentiment. The evidence supports these predictions. In particular, we find that discounts on closed end funds narrow when small stocks do well, as would be expected if closed end funds were subject to the same sentiment as small stocks, whim tern. also to be held by individual investors. The evidence thus suggests that investor sentiment affects security returns.
