Behavioural Economics

The controversial science that claims to have revolutionised economics. For centuries, economics was dominated by the idea that we are rational individuals who optimise our own 'utility'. Then, in the 1970s, psychologists demonstrated that the reality is a lot messier. We don't really know what our utility is, and we care about people other than ourselves. We are susceptible to external nudges. And far from being perfectly rational we are prone to 'cognitive biases' with complex effects on decision-making, such as forgetting to prepare for retirement. David Orrell explores the findings from psychology and neuroscience that are shaking up economics - and that are being exploited by policy-makers and marketers alike, to shape everything from how we shop for food, to how we tackle societal happiness or climate change. Finally, he asks: is behavioural economics a scientific revolution, or just a scientific form of marketing?

Traditionally economists have based their economic predictions on the assumption that humans are super-rational creatures, using the information we are given efficiently and generally making selfish decisions that work well for us as individuals. Economists also assume that we're doing the very best we can possibly do - not only for today, but over our whole lifetimes too. But increasingly the study of behavioural economics is revealing that our lives are not that simple. Instead, our decisions are complicated by our own psychology. Each of us makes mistakes every day. We don't always know what's best for us and, even if we do, we might not have the self-control to deliver on our best intentions. We struggle to stay on diets, to get enough exercise and to manage our money. We misjudge risky situations. We are prone to herding: sometimes peer pressure leads us blindly to copy others around us; other times copying others helps us to learn quickly about new, unfamiliar situations. This Very Short Introduction explores the reasons why we make irrational decisions; how we decide quickly; why we make mistakes in risky situations; our tendency to procrastination; and how we are affected by social influences, personality, mood and emotions. The implications of understanding the rationale for our own financial behaviour are huge. Behavioural economics could help policy-makers to understand the people behind their policies, enabling them to design more effective policies, while at the same time we could find ourselves assaulted by increasingly savvy marketing. Michelle Baddeley concludes by looking forward, to see what the future of behavioural economics holds for us. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

In this book, David K. Levine questions the idea that behavioral economics is the answer to economic problems. He explores the successes and failures of contemporary economics both inside and outside the laboratory, and asks whether popular behavioral theories of psychological biases are solutions to the failures. The book not only provides an overview of popular behavioral theories and their history, but also gives the reader the tools for scrutinizing them.

- Incorporates the latest experimental evidence from across economics, psychology and neuroscience to provide cutting-edge introduction for students. - Structured around three key settings – individuals, small groups and larger impersonal groups (e.g. markets) – this text provides a logical framework for the study of economic decision-making. - Includes discussion of emotions including fairness, trust, selfishness and altruism on both a micro and macro level to show how they can influence personal decision making as well as entire economies.

Choice, Behavioural Economics and Addiction is about the theory, data, and applied implications of choice-based models of substance use and addiction. The distinction between substance use and addiction is important, because many individuals use substances but are not also addicted to them. The behavioural economic perspective has made contributions to the analysis of both of these phenomena and, while the major focus of the book is on theories of addiction, it is necessary also to consider the behavioural economic account of substance use in order to place the theories in their proper context and provide full coverage of the contribution of behavioural economics to this field of study. The book discusses the four major theories of addiction that have been developed in the area of economic science/behavioural economics. They are: . hyperbolic discounting . melioration . relative addiction . rational addiction The main objective of the book is to popularise these ideas among addiction researchers, academics and practitioners. The specific aims are to articulate the shared and distinctive elements of these four theories, to present and discuss the latest empirical work on substance abuse and addiction that is being conducted in this area, and to articulate a range of applied implications of this body of work for clinical, public health and public policy initiatives. The book is based on an invitation-only conference entitled, Choice, Behavioural Economics and Addiction: Theory, Evidence and Applications held at the University of Alabama at Birmingham, March 30 - April 1, 2001. The conference was attended by prominent scientists and scholars, representing a range of disciplines concerned with theories of addiction and their consequences for policy and practice. The papers in the book are based on the papers given at the above conference, together with commentaries by distinguished experts and, in many cases, replies to these comments by the presenters.

Standard models in economics and finance usually assume that people are rational, self-interested maximisers, effectively co-ordinated via the invisible hand of the price mechanism. Whilst these approaches produce tractable, simple models, they cannot fully capture the uncertainties and instabilities that affect everyday choices in today’s complex world. Insights from the other social and behavioural sciences can help to fill the gap and behavioural economics is the subject which brings economics and finance together with psychology, neuroscience and sociology. Behavioural Economics and Finance introduces the reader to some of the key concepts and insights from this rich, inter-disciplinary approach to real-world decision-making.

Behavioral economics has potential to offer novel solutions to some of today's most pressing public health problems: How do we persuade people to eat healthy and lose weight? How can health professionals communicate health risks in a way that is heeded? How can food labeling be modified to inform healthy food choices? Behavioral Economics and Public Health is the first book to apply the groundbreaking insights of behavioral economics to the persisting problems of health behaviors and behavior change. In addition to providing a primer on the behavioral economics principles that are most relevant to public health, this book offers details on how these principles can be employed to mitigating the world's greatest health threats, including obesity, smoking, risky sexual behavior, and excessive drinking. With contributions from an international team of scholars from psychology, economics, marketing, public health, and medicine, this book is a trailblazing new approach to the most difficult and important problems of our time.
