Behavioral economist and New York Times bestselling author Dan Ariely offers a much-needed take on the irrational decisions that led to our current economic crisis.

• Why is paying for things painful?
• Why are we comfortable overpaying for something in the present just because we’ve overpaid for it in the past?
• Why is it easy to pay $4 for a soda on vacation, when we wouldn’t spend more than $1 on that same soda at our local grocery store?

We think of money as numbers, values, and amounts, but when it comes down to it, when we actually use our money, we engage our hearts more than our heads. Emotions play a powerful role in shaping our financial behavior, often making us our own worst enemies as we try to save, access value, and spend responsibly. In Dollars and Sense, bestselling author and behavioral economist Dan Ariely teams up with financial comedian and writer Jeff Kreisler to challenge many of our most basic assumptions about the precarious relationship between our brains and our money. In doing so, they undermine many of personal finance’s most sacred beliefs and explain how we can override some of our own instincts to make better financial choices.

Exploring a wide range of everyday topics—from the lure of pain-free spending with credit cards to the  pitfalls of household budgeting to the seductive power of holiday sales—Ariely and Kreisler demonstrate how our misplaced confidence in our spending habits frequently leads us astray, costing us more than we realize, whether it’s the real value of the time we spend driving forty-five minutes to save $10 or our inability to properly assess what the things we buy are actually worth. Together Ariely and Kreisler reveal the emotional forces working against us and how we can counteract them. Mixing case studies and anecdotes with concrete advice and lessons, they cut through the unconscious fears and desires driving our worst financial instincts and teach us how to improve our money habits.

The result not only reveals the rationale behind our most head-scratching financial choices but also offers clear guidance for navigating the treacherous financial landscape of the brain. Fascinating, engaging, funny, and essential, Dollars and Sense provides the practical tools we need to understand and improve our financial choices, save and spend smarter, and ultimately live better.

Dan Ariely's three New York Times bestselling books on his groundbreaking behavioral economics research, Predictably Irrational, The Upside of Irrationality, and The (Honest) Truth About Dishonesty, are now available for the first time in a single volume.

The New York Times bestselling author of Predictably Irrational and The Upside of Irrationality returns with thought-provoking work to challenge our preconceptions about dishonesty and urge us to take an honest look at ourselves.

• Does the chance of getting caught affect how likely we are to cheat?
• How do companies pave the way for dishonesty?
• Does collaboration make us more honest or less so?
• Does religion improve our honesty?

Most of us think of ourselves as honest, but, in fact, we all cheat. From Washington to Wall Street, the classroom to the workplace, unethical behavior is everywhere. None of us is immune, whether it's the white lie to head off trouble or padding our expense reports. In The (Honest) Truth About Dishonesty, award-winning, bestselling author Dan Ariely turns his unique insight and innovative research to the question of dishonesty.

Generally, we assume that cheating, like most other decisions, is based on a rational cost-benefit analysis. But Ariely argues, and then demonstrates, that it's actually the irrational forces that we don't take into account that often determine whether we behave ethically or not. For every Enron or political bribe, there are countless puffed résumés, hidden commissions, and knockoff purses. In The (Honest) Truth About Dishonesty, Ariely shows why some things are easier to lie about; how getting caught matters less than we think; and how business practices pave the way for unethical behavior, both intentionally and unintentionally. Ariely explores how unethical behavior works in the personal, professional, and political worlds, and how it affects all of us, even as we think of ourselves as having high moral standards.

But all is not lost. Ariely also identifies what keeps us honest, pointing the way for achieving higher ethics in our everyday lives. With compelling personal and academic findings, The (Honest) Truth About Dishonesty will change the way we see ourselves, our actions, and others.

“Dan Ariely is a genius at understanding human behavior: no economist does a better job of uncovering and explaining the hidden reasons for the weird ways we act.” — James Surowiecki, author of The Wisdom of Crowds

Behavioral economist and New York Times bestselling author of Predictably Irrational Dan Ariely returns to offer a much-needed take on the irrational decisions that influence our dating lives, our workplace experiences, and our temptation to cheat in any and all areas. Fans of Freakonomics, Survival of the Sickest, and Malcolm Gladwell’s Blink and The Tipping Point will find many thought-provoking insights in The Upside of Irrationality.

Dan Ariely, the New York Times bestselling author of Predictably Irrational, and illustrator Matt R. Trower present a playful graphic novel guide to better decision-making, based on the author’s groundbreaking research in behavioral economics, neuroscience, and psychology.

The internationally renowned author Dan Ariely is known for his incisive investigations into the messy business of decision-making. Now, in Amazing Decisions, his unique perspective—informed by behavioral economics, neuroscience, and psychology—comes alive in the graphic form. The illustrator Matt R. Trower’s playful and expressive artwork captures the lessons of Ariely’s groundbreaking research as they explore the essential question: How can we make better decisions?

Amazing Decisions follows the narrator, Adam, as he faces the daily barrage of choices and deliberations. He juggles two overlapping—and often contradictory—sets of norms: social norms and market norms. These norms inform our thinking in ways we often don’t notice, just as Adam is shadowed by the “market fairy” and the “social fairy,” each compelling him to act in certain ways. Good decision-making, Ariely argues, requires us to identify and evaluate the forces at play under different circumstances, leading to an optimal outcome. Amazing Decisions is a fascinating and entertaining guide to developing skills that will prove invaluable in personal and professional life.

Combinando un gran sentido del humor y profundos conocimientos de economía conductual, Dan Ariely se adentra en el mundo absolutamente ilógico de las finanzas personales, las del día a día, para ayudar a entender por qué tomamos algunas decisiones, muchas de ellas equivocadas.

En Las trampas del dinero, Ariely y Kreisler (un experto financiero y gran divulgador) analizan una amplia gama de ejemplos cotidianos (por qué duele menos pagar con tarjeta, las trampas que nos hacemos a nosotros mismos en el presupuesto familiar, las tentadoras ofertas a las que sucumbimos en vacaciones…) para demostrar cómo nuestras ideas sobre la gestión del dinero a menudo están equivocadas y nos convierten en nuestros peores enemigos.

Fascinante, divertido e imprescindible, sin duda este libro es una gran inversión para todo aquel que quiera entender mejor las trampas en las que caemos a la hora de gestionar nuestro dinero para poder ahorrar, gastar de una forma más inteligente y, en definitiva, vivir mejor.

Sample chapters from Predictably Irrational and Upside of Irrationality.

Predictably Irrational

Why do our headaches persist after we take a one-cent aspirin but disappear when we take a fifty-cent aspirin?

Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?

When it comes to making decisions in our lives, we think we're making smart, rational choices. But are we?

In this newly revised and expanded edition of the groundbreaking New York Times bestseller, Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. From drinking coffee to losing weight, from buying a car to choosing a romantic partner, we consistently overpay, underestimate, and procrastinate. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable—making us predictably irrational.

Upside of Irrationality

The provocative follow-up to the New York Times bestseller Predictably Irrational

• Why can large bonuses make CEOs less productive?
• How can confusing directions actually help us?
• Why is revenge so important to us?
• Why is there such a big difference between what we think will make us happy and what really makes us happy?

In his groundbreaking book Predictably Irrational, social scientist Dan Ariely revealed the multiple biases that lead us into making unwise decisions. Now, in The Upside of Irrationality, he exposes the surprising negative and positive effects irrationality can have on our lives. Focusing on our behaviors at work and in relationships, he offers new insights and eye-opening truths about what really motivates us on the job, how one unwise action can become a long-term habit, how we learn to love the ones we're with, and more.

Drawing on the same experimental methods that made Predictably Irrational one of the most talked-about bestsellers of the past few years, Ariely uses data from his own original and entertaining experiments to draw arresting conclusions about how—and why—we behave the way we do. From our office attitudes, to our romantic relationships, to our search for purpose in life, Ariely explains how to break through our negative patterns of thought and behavior to make better decisions. The Upside of Irrationality will change the way we see ourselves at work and at home—and cast our irrational behaviors in a more nuanced light.
