We are drawing closer to psychology and medicine. Using random samples from many nations: Researchers try to find what influences the psychological wellbeing of (i) individuals (ii) nations. Today I would like to ask four questions. #1 #1 st 21 In the century, should our society’s goal be happiness rather than GDP? #2 #2 What actually happens to a person when they get a lot of money (say by winning the lottery)? #2 What actually happens to a person when they get a lot of money (say by winning the lottery)? #3 #3 Could physiological measures, like heart rate and blood pressure, be used as proxies for well-being? #3 Could physiological measures, like heart rate and blood pressure, be used as proxies for well-being? #4 #4 How should we think about the causes of the current financial crisis? • A fundamental question: Is modern society going in a good direction? Is modern society going in a good direction? Are we getting happier? Possibly not…..

Preferably not like this… Italy 6 England 0 What kind of data do we use in research on well-being? The types of sources British Household Panel Study (BHPS) German Socioeconomic Panel Australian HILDA Panel General Social Survey of the USA Eurobarometer Surveys Labour Force Survey from the UK World Values Surveys NCDS 1958 cohort Various statistical methods Some cheery news: Some cheery news: In Western nations, most people seem happy with their lives Some cheery news: In Western nations, most people seem happy with their lives The distribution of life-satisfaction levels among British people 35 Percentage of Population 30 25 20 15 10 5 0 1 2 3 4 5 6 Self-rated Life Satisfaction Source: BHPS, 1997-2003. N = 74,481 7 But obviously life is a mixture of ups and downs Statistically, wellbeing in panels is strongly correlated with life events ..good and bad. Big effects Unemployment Divorce Marriage Bereavement Friendship networks Health [No effects from children] Much of the new research follows people through time. eg. Andrew Clark’s work The unhappiness from bereavement So people adapt So people adapt But that has a downside…. The happiness from marriage And should you invest in a baby? Happiness and children An important question in a modern society is the impact of divorce. Divorce eventually makes people happier Divorce eventually makes people happier • Other findings Happiness is also U-shaped over the life course The pattern of a typical person’s happiness through life Average life satisfaction score 5.6 5.5 5.4 5.3 5.2 5.1 5.0 4.9 15-20 21-30 31-40 41-50 Age group 51-60 61-70 This holds in various settings This holds in various settings For example, we see the same age pattern in mental health among a recent sample of 800,000 UK citizens: [Blanchflower and Oswald, Social Science & Medicine, 2008] New Perspectives The probabilityon ofJob depression by age Satisfaction Well-Being Males, LFS data and set 2004-2006 0.02 DTI’S FOURTH LABOUR MARKET RESEARCH CONFERENCE ORGANISER: EMPLOYMENT MARKET ANALYSIS & RESEARCH (EMAR) Regression coefficient 0.015 0.01 0.005 0 -0.005 -0.01 1938 1942 1946 1950 1954 1958 1962 1966 Year of birth 1970 1974 1978 1982 1986 1990 New Perspectives onamong Job females: LFS data Depression by age Satisfaction and Well-Being 2004-2006Q2 DTI’S FOURTH LABOUR MARKET RESEARCH CONFERENCE 0.002 ORGANISER: EMPLOYMENT MARKET ANALYSIS & RESEARCH (EMAR) Regression coefficient 0 -0.002 -0.004 -0.006 -0.008 -0.01 -0.012 -0.014 1942 1946 1950 1954 1958 1962 1966 Year of birth 1970 1974 1978 1982 1986 1990 Now what about money? Now what about money? The data show that richer people are happier and healthier. But in particular Relative income is what seems to matter to humans. (consistent with Easterlin’s paradox) In terms of economic theory: u = u(y/y*) where y* is what other people earn. For example Di Tella et al REStats 2003, Blanchflower and Oswald JPubEcon 2004, and Luttmer QJE 2005 show income is monotonic in happiness equations for 11 industrial countries. But is there really good causal evidence? One recent attempt (Gardner-Oswald, Journal of Health Economics 2007): Studying windfalls is one approach:. So what happens to someone who gets a largish lottery win? Remarkably There is no immediate effect on well-being as measured by happiness or financial satisfaction. In our data Strikingly, even the person who receives the equivalent of 1 million US dollars reports a fall, in time t1, in financial satisfaction (ie. satisfaction with the household’s income). But, after three years, a large effect on satisfaction suddenly becomes apparent. Lottery wins raise mental well-being But the puzzle remains But the puzzle remains There is a delay. But the puzzle remains There is a delay. The longitudinal lottery work finds the effect of a win takes at least two years to show up in mental well-being scores. Where will research head in the future? An interesting border is between happiness and medicine An interesting border is between happiness and medicine • Is it possible that we can find physiological correlates with human well-being? • Perhaps to broaden the standard policy goal of GDP? Some of our latest work: Statistical links between the heart and income and happiness. To clinicians High blood pressure is potentially a sign of mental strain and low well-being Some regression evidence Some regression evidence When we estimate a life-satisfaction equation LS = f (high blood pressure, control variables) Hypertension enters negatively in a 10,000 sample from NCDS cohort and a 15,000 sample from Eurobarometers But how about high blood pressure as a national measure of well-being? (Blanchflower and Oswald, 2008 Journal of Health Economics) Figure 2. The Inverse Correlation Between Hypertension and Life Satisfaction: 16 European Nations Aggregated into Quartiles 50 Percentage of citizens very satisfied with their lives Percentage of citizens very satisfied with their lives Across nations, hypertension and happiness are inversely correlated 40 30 Ireland Denmark N'Lands Sweden Spain France Lux UK 20 10 Austria Italy Belgium Greece E. Germany W. Germany Portugal Finland 0 Countries in the lowest quartile of blood-pressure Countries in the highest quartile of blood-pressure Some of our latest work: It is known that heart rate rises under stress.

Pulse: Average heart rate is about 75 beats per minute. Pulse and Money We find that for every extra 40,000 Euros a year, heart rate is 1 beat a minute slower. Heart-Rate Equations (joint work with David G Blanchflower) There are deep connections between happiness, money and the behaviour of the heart. Finally Happiness, herds and the financial crisis Why did we get into the crisis, and how will human happiness be affected? The evidence suggests that when a person is made unemployed: The evidence suggests that when a person is made unemployed: • 20% of the fall in mental well-being is due to the decline in their income • 80% is due to non-pecuniary things (loss of self-esteem, status..). Countries are happier if they have low unemployment and inflation, and generous welfare benefits. ‘Fear’ depresses happiness. R. Di Tella, R. Macculloch, A.J. Oswald American Economic Review, 2001. In a recession there is a widespread decline in mental well-being, we think because of the generalized insecurity. Herds and keeping up with the Joneses • "Men … think in herds; they go mad in herds, … they only recover their senses slowly, and one by one." C. Mackay Extraordinary Popular Delusions and the Madness of Crowds, by Charles MacKay, published in 1841. Extraordinary Popular Delusions and the Madness of Crowds, by Charles MacKay, published in 1841. Far from the Madding Crowd, by Thomas Hardy, published in 1874. Why does it happen? Why does it happen? We know that people care about relative things. On a technical note To economists and any mathematicians here: On a technical note To economists and any mathematicians here: I have in mind a class of problem where utility depends on relative actions. Imagine a person is choosing an action a to solve: Maximize u(a) + v(a – a*) – c(a) where a* is what everyone else is doing. Then if v is concave (convex) in status, it is rational to act similarly to (deviantly from) the herd. Subconsciously, humans are frightened of falling behind: Subconsciously, humans are frightened of falling behind: • Bank lenders and brokers felt they had to match rivals. • Home buyers paid extraordinary prices in order to keep up. • Money managers -- rewarded on relative performance against other managers -- copied what the others did. When rewards depend on your relative position it will routinely be When rewards depend on your relative position it will routinely be (i) dangerous to question whether the whole group’s activity is flawed (ii) rational simply to compete hard within the rules that govern success. When rewards depend on your relative position it will routinely be (i) dangerous to question whether the whole group’s activity is flawed (ii) rational simply to compete hard within the rules that govern success. Correct dotcom analysts were fired. The pressures for conformity are strong. Herd behaviour is very often natural and individually rational. But it has the potential to be disastrous for the group. To any students here These psychological forces are powerful and will come around again, a number of times, in your lifetime. • Now to the housing market, which started our problems. Real house prices in the United States over a century Real house prices in the UK 1975-2006 So all the historical data suggested that house prices were unsustainable. Yet -- even two or three years ago near the peak -- few people spoke about the apparent likelihood of a crash. Yet -- even two or three years ago near the peak -- few people spoke about the apparent likelihood of a crash. …another kind of herd action. Unfortunately, we do have to have some lean years Some ideas to end: Conclusions #1 In the next century, new measures of human well-being will be required. Conclusions #2 As social scientists, we need to understand better the connections between mental and physical health. Conclusions #3 Heart-rate and blood pressure data have particular potential in policy design. Conclusions #4 Social scientists will, I believe, collaborate more with doctors and epidemiologists. Conclusions #5 Economists need to incorporate herd behaviour more fully into standard models. More broadly on well-being More broadly on well-being Policy in the coming century may need to concentrate on non-materialistic goals.
