This is essentially a review of a fascinatingly engaging book by Professor Richard Thaler (University of Chicago), 2017 Nobel prize in Economics and Professor Cass Sunstein (Harvard University). It is entitled Nudge: Improving Decisions About Heath, Wealth, and Happiness. The major premise of the book is that most human beings do not make decisions in the way that is often characterized in elementary economic text books. This premise is supported by a wealth of evidence that provides a wide array of suggestions about how individuals, policy makers, governments, the private sector and civil society can make better choices that benefit society as a whole. It has been aptly described as a manifesto to help people, government agencies, companies and charities make better decisions.
The methodology used to analyze how the environmental conditions often influence choices fall under the rubric of Behavioral Economics, a relatively new area of research combining economics and psychology. This innovative approach to documenting human behavior demonstrates that the apparently 'free choices' people make are affected by the way 'options' are presented to them.
This book is indeed relatable. It conveys difficult principles through a range of palatable examples. Among the most salient include:
Most obvious is their concern about governments playing a better role in guiding choices. As a result, they demonstrate the familiar arguments for why people should simply be left to make choices on their own, and especially for why government should stay strictly out of the way, as having little practical force. Of great significance is that "in many important areas of choice that matter, the operative question is not whether to bias people’s decisions, but in which direction".
Thaler and Sustein provide several examples of a nudge as "anything that influences our choice".
a) A successful nudge is exemplified in a 'Save for Tomorrow's program', where
firms offer employees an opportunity to join and automatically increase saving
rates whenever an employee gets a raise.
b) Nudges that make a difference through 'choice environments' lead to better
investments, more retirement savings, less obesity, more charitable giving, a
cleaner planet and improved educational system.
c) Nudges that are promoted through 'choice architecture' define the context in
which you make your choice. There are those that will influence what you
choose to eat like displays of food in a cafeteria. Others that make rules about
what you see/know or what you do not, such as doctors, employers, credit card
companies, banks and even parents. They show that by carefully designing the
choice architecture, dramatic improvements in the decisions are more likely to
be made by individuals and groups.
d) Nudges as essential ingredients of appropriate public policy steer people
toward healthier, safer, more prosperous lives while also addressing pressing
issues like environmental damage and the rising cost of health care. They take
account of the odd realities of human behavior like the deep and unthinking
tendency to conform.
"NUDGE is about choices -- how we make them and how we're led to make better ones"
There is much more to this book. The authors show that it is possible for people to make better choices and retain or even expand their freedoms. They illustrate how people go into 'auto pilot mode' by procrastinating because a decision is hard; because too many choices result in information overload; because the world has become complicated; and because the high stakes for achieving in the current environment make people tense.
This book is both amusing and elucidating. It has been described as 'a jolly economic romp but with serious lessons within'. The distinguished professors chose to label their approach as "libertarian paternalism" Herein lies a cause to ponder. Libertarian: as people retain the right to make their own choices. Paternalism: as governments, employers and those in charge continuously nudge people in the direction that they think will make them better off. The unresolved issue is whether libertarian paternalism can unify the left and the right ideologically as the authors seem to suggest or is it the tipping point in our understanding of human development.
