Behavioural economics and better choices
Subject
Themes
People make decisions every day that shape their health, wealth, and happiness, yet these choices frequently work against their own best interests. Research in behavioural economics and psychology demonstrates that humans routinely fall prey to cognitive biases, succumb to immediate temptation over long-term wellbeing, and rely on mental shortcuts that lead to systematic errors. The traditional economic model assumes rational actors who consistently maximise their own welfare, but real people (Humans rather than theoretical Econs) regularly fail to save enough for retirement, choose unsuitable healthcare plans, eat unhealthy foods, and make financial decisions they later regret.

Nudge emerged at a pivotal moment when behavioural economics was transitioning from academic curiosity to policy mainstream. Daniel Kahneman won the Nobel Prize in Economics in 2002 for work demonstrating systematic deviations from rational choice theory, lending credibility to psychological…
Traditional economic theory relies on a model of human behaviour that assumes perfect rationality. This theoretical creature, dubbed Homo economicus or 'Econ' for short, possesses unlimited cognitive abilities, perfect self-control, and unwavering dedication to maximising personal welfare. Econs…
Every decision people make occurs within a context that shapes their choices, often in ways they never notice. The person or institution that designs this context is a choice architect, wielding subtle but powerful influence over outcomes. A cafeteria supervisor deciding where to place healthy…
The combination of the words 'libertarian' and 'paternalism' strikes many as contradictory or even offensive. Libertarians resist government interference with individual choice, whilst paternalism suggests authorities imposing their judgments on others. Yet properly understood, the two concepts not…
Most people know they should save more for retirement, yet fail to do so. They understand intellectually that they will need money in old age, but present consumption proves far more tempting than future security. This gap between intention and action reflects fundamental features of human…
Healthcare decisions rank among the most important and difficult choices people face. The stakes are enormous (health, life, death), the options are often complex (dozens of insurance plans, multiple treatment alternatives), the information is technical (medical terminology, statistical risks), and…
Choice architects design the contexts in which people make decisions, wielding subtle but powerful influence over outcomes. A cafeteria supervisor rearranging food displays represents a classic example. By varying whether desserts appear first or last, placing carrots or chips at eye level, and…
Self-control problems pervade human behaviour. People know they should save more, exercise regularly, eat healthily, and avoid addiction, yet they repeatedly fail to follow through. This gap between intention and action cannot be explained by standard economic models assuming consistent preferences.…
People benefit most from nudges in domains where they lack experience, have poor information, receive slow or infrequent feedback, face complex choices, or struggle with self-control. Choosing ice cream flavours requires no nudging because people have extensive experience, immediate feedback, and…
Traditional approaches to encouraging retirement savings have focused on education (teaching people why they should save) and incentives (offering tax benefits or employer matches). Yet participation rates in voluntary pension schemes remain stubbornly low, particularly among groups who most need to…
Credit markets feature complex products designed by sophisticated firms and purchased by consumers who often lack financial expertise. Credit cards, mortgages, student loans, and payday lending all present opportunities for poor decisions that can have lasting consequences. The products themselves…
The Medicare Part D prescription drug benefit illustrates both the promise and pitfalls of offering extensive choice. Designed to help seniors afford medications, the programme allows private insurers to offer competing plans with varying premiums, deductibles, formularies, and coverage gaps. In…
Environmental problems from climate change to local pollution present collective action challenges where individual incentives diverge from social welfare. People benefit personally from driving large vehicles, using electricity freely, and consuming disposable products, whilst the environmental…
Debates about healthcare mandates illustrate tensions between libertarian and paternalistic impulses. Should government require people to purchase health insurance, or should individuals remain free to go uninsured and accept the consequences? Traditional libertarians resist mandates as unwarranted…
Specific applications of nudging span diverse domains, demonstrating how small changes in choice architecture can produce large improvements. Giving more tomorrow (committing future income to charitable giving) applies the Save More Tomorrow logic to philanthropy. Charity debit cards that round…
Libertarian paternalism offers a genuine third way between two failed extremes: unrestricted markets that ignore human cognitive limitations, and heavy-handed government mandates that eliminate choice. The approach accepts that people are not perfectly rational calculators but rejects the conclusion…
