STOCKHOLM/CHICAGO--U.S. academic Richard Thaler, who helped popularise the idea of "nudging" people towards doing what was best for them, won the 2017 Nobel Economics Prize on Monday for his work on how human nature affects supposedly rational markets.
Influential in the field of behavioural economics, his research showed how traits such as lack of self-control and fear of losing what you already have prompt decisions that may not have the best outcome in the longer term.
"I think the most important impact (of my research) is the recognition that economic agents are human and economic models have to incorporate that," Thaler, a professor at the University of Chicago Booth School of Business, said in a call broadcast at the Nobel news conference.
Asked at a separate news conference in Chicago if it was difficult to get traditional, data-oriented economists to embrace his ideas, Thaler said it was "impossible...economists don't do a lot of embracing actually."
Awarding the 9 million Swedish crown ($1.1 million) prize, the Royal Swedish Academy of Sciences said: "Richard Thaler's contributions have built a bridge between the economic and psychological analyses of individual decision-making."
"His empirical findings and theoretical insights have been instrumental in creating the new and rapidly expanding field of behavioural economics, which has had a profound impact on many areas of economic research and policy."
Thaler brought to prominence the idea of "nudge" economics, where individuals are subtly guided toward beneficial behaviours without heavy-handed compulsion, the theme of a 2008 book he co-wrote which caught the eye of policymakers around the world. In research focused on self control - or the lack of it - Thaler touched on an age-old problem: why New Year's resolutions to change aspects of your life are notoriously hard to keep.
The issue has relevance for economics as individuals' tendency to fall prey to temptation often negatively affects plans to, for instance, save for retirement. Together with Professor Cass Sunstein, he argued that society - while maintaining freedom of choice - should actively try to guide individuals in the right direction. Their book, titled 'Nudge: Improving Decisions about Health, Wealth, and Happiness' became popular with some western politicians seeking ways to encourage their citizens to save and live healthily, without incurring voters' wrath for raising taxes or banning behaviour outright.
"This has also been used in public pension systems in the United States and the general idea of 'nudging' ... has made a breakthrough in public policy making," Torsten Persson, economics prize committee member, told Reuters. "There's also a nudging unit for the UK government, there's one for the Australian government, it even affects the Swedish government when they think about these things."'
David Laibson, chair of Harvard University’s economics department, said many of Thaler's theories have been widely applied by business and government, aiming to get individuals to do a range of actions such as paying parking tickets and getting flu shots. "If you live in a developed country, there's some firm or entity that has read these ideas and started to affect your life," Laibson said.
Influential in academic circles, the movie-going public may have noticed Thaler make a brief cameo in the 2015 film "The Big Short", explaining the so-called "hot-hand fallacy" where past success is expected to also warrant success in the future, with pop star Selena Gomez.
"I basically have made a career stealing ideas from psychologists," Thaler joked at the Chicago news conference.
Asked how he would spend his prize money, he said: "I will spend it as irrationally as possible."
