Issues in the Measurement of
Well-being
Andrew E. Clark (Paris School of Economics and IZA)
http://www.parisschoolofeconomics.com/clark-andrew/
Economics and Psychology Masters Course
Three concepts of well-being
• Objective list – decided from “up above”
– Meet material, social and psychological needs
– Rights, economic resources, health, political freedom,
freedom of thought, etc
• Preference satisfaction / desire fulfilment
– Individuals get what they want (role of resources)
• Mental state
– Hedonistic accounts; evaluative accounts
– ‘Subjective’ well-being
– Experienced utility
2
• Objective lists have often appeared in Macro
debates about performance – how well a
country as a whole is doing
– GDP.
– The misery index AKA the Okun index
(unemployment rate plus inflation)
• Widely used in policy debates
– unemployment rate; suicide rate; education level;
access to green space; income inequality; etc
– Of the kind HDI/HDI+
– Or Community Health Indicators
3
• Which is not to say that there are no concerns
about such nice “list” measures:
–
–
–
–
4
What should be on the list?
How can the items be compared?
Are the weights the same for everyone?
Paternalism: who decides?
Capabilities as a list
• Amartya Sen’s “capability approach”
• A challenge to consequentialist utilitarianism, and the
Pareto criterion
• Start from a conception of what makes a good human life:
people, not goods
• Capability Approach:
– what people are free to do as well as what they actually do.
– opportunities result from ‘capabilities’ – what you can do.
– these are distinct from ‘functionings’ – what you do.
Nussbaum’s list of capabilities
1. Life: not dying prematurely
2. Bodily health: good health; adequately nourished; shelter
3. Bodily integrity; mobility; free from violence; choice in sex
and reproduction
4. Senses, imagination, and thought: education, religion, art
5. Emotions: attachments, love
6. Practical reason: form conception of the good, planning of
life
7. Affiliation: social interaction; respect and dignity
8. Other species: concern and relation to animals, plants,
nature
9. Play: laugh, play, enjoy recreational activities
10. Control over one’s environment: political participation;
property, employment.
Human Development Index (HDI)
• Based on Sen’s idea of capabilities, added to
Macro measures of performance
• Rationale: GDP per capita gives an incomplete
picture of development and well-being
– can be supplemented by information on the
opportunities people have
• UNDP has published the HDR every year
since 1990; this includes the HDI by country.
United Nations Development Report 1990
• “Human development is a process of enlarging peoples
choices. The most critical of these wide ranging choices
are to live a long and healthy life, to be educated and to
have access to resources needed for a decent standard
of living.”
• “No one can guarantee human happiness, and the
choices people make are their own concern. But the
process of development should at least create a
conducive environment for people, individually and
collectively, to develop their full potential and to have a
reasonable chance of leading productive and creative
lives in accordance with their needs and interests”
The Human Development Index
To calculate each dimension index …
Each indicator index …
HDI data from UNDR
• The last column shows that the ranking of
countries by GDP per capita is not the same as that
by HDI
• Some countries do better than their GDP would
imply (the Scandinavians, Madagascar)
• Others do worse
• The HDI adds new information to answer the
question of how well a country is doing
• Despite their relatively high incomes, none of the
oil-producing countries has a high HDI
Gender-related Development Index:
HDR 1995
• UNDP acknowledges key role for gender equality
• development per se may not contribute to gender
equality
• HDI measures average achievement
• GDI adjusts to reflect male/female inequalities
• Calculate dimension indices by gender
• Use inequality-sensitive aggregation
• Then combine into GDI.
Contruction of the GDI
Gender specific values …
“Inequality-sensitive” aggregation
• average well-being of men and women: Dm, Df
• proportion of men and women : pm, pf
• aggregate population well-being: W
• equity-neutral aggregation:
W1 = pmDm + pfDf
• equity-sensitive aggregation:
W2 = [ pmDm-r + pfDf-r ] -1/r
• if r = -1, then W1 = W2, and thus equity neutral
• if r > -1, then inequality aversion; GDI uses r = 1.
GDI data from UNDR
GDI Map
Main findings of HDR 95
Benefits of development do not trickle down to
everybody; it is not gender neutral
• Most of men’s work is paid; most of women’s
work is unpaid:
– this impacts on social status (employment confers
status)
• GDP per capita alone, or HDI, does not explain
rank of country in GDI.
• In 2010, both the variables used to construct the
HDI changed somewhat. And the GDI was
replaced by the Gender Inequality Index. A new
index was introduced that takes into account
inequality in the dimensions of the HDI over the
whole population (Inequality-adjusted HDI).

23
Preference satisfaction accounts
• Well-being
– the more you satisfy your preferences and fulfil your
desires the higher your well-being is considered to
be.
• In line with utility theory
– preferences inferred from the choices people make
• Concerns:
– Do people want/know what is good for them?
– What to do about “anti-social” preferences?
24
Mental state accounts
• Well-being
– how individuals feel / think
• Self-reported mood, emotions
– happy / sad / excited / bored
• Self-reported evaluation
– “how satisfied are you with your life?”
• Concerns:
– Adaptation and changing aspirations: : hedonic
treadmill
– Personality traits
– These mean that objective and subjective may not
“match”.
25
Adaptation is not universal
• We do not fully adapt to some circumstances and
experiences
– Positive
• e.g. friendships
– Negative
• e.g. pain, noise, unemployment, poverty
• Important differences in degree and speed of
adaptation and
• some evidence that baseline levels of SWB can
change over time (for example, following
unemployment)
26
BHPS Well-being questions
The British Household Panel Survey (BHPS).
• See <http://www.iser.essex.ac.uk/ulsc/bhps/>
• Annual panel (longitudinal) survey since 1991.
• Wave 18 in September 2008
• Wide range of variables from same individuals
and households each year.
• E.g. in Wave 12 (2002):
– N = 17,339, aged 18-85
27
The General Health Questionnaire 12
(GHQ-12)
Have you recently:
1. been able to concentrate
2. lost much sleep over worry
3. felt that you were playing a useful part in things
4. felt capable of making decisions
5. Felt constantly under strain
6. felt you could not overcome difficulties
7. been able to enjoy normal activities
8. been able to face up to problems
9. Been feeling unhappy and depressed
10. been Losing confidence
11. been thinking of yourself as worthless
12. been feeling reasonably happy
28
Satisfaction Questions
Here are some questions about how you feel about your life.
Please tick the number which you feel best describes how
dissatisfied or satisfied you are with the following aspects of your
current situation.
Your life overall
[1] [2] [3] [4] [5] [6] [7]
not satisfied at all
completely satisfied
This question is also asked about domains of life:
e.g. health, income, house, partner ...
29
These “behave” the way we think that they should:

ONS Happiness Survey Questions Revealed
After becoming Conservative leader in 2005, David Cameron said gauging
people's feelings was one of the "central political issues of our time".
"It's time we admitted that there's more to life than money and it's time we
focused not just on GDP but on GWB - general well-being," he said.
The ONS will add the subjective questions to its next annual Integrated
Household Survey
The questions will include:
Overall, how satisfied are you with your life nowadays?
Overall, how happy did you feel yesterday?
Overall, how anxious did you feel yesterday?
Overall, to what extent do you feel the things you do in your life are
worthwhile?
www.bbc.co.uk/news/uk-12566965
Does subjective well-being mean anything (1)
Concern:
Does it make sense to treat the happiness or
life satisfaction scores as if they were cardinal
and interpersonally comparable?
Reality:
Econometric models assuming cardinality and
ordinality give roughly same results
Meaning: people “split up” verbal labels into
roughly equal blocks
32
Does subjective well-being mean anything (2)
Concern:
Are the life satisfaction or happiness questions
reliable? Are they valid? Can people recall?
Reality:
• Sensitive to wording, and question ordering.
• Can be experimentally manipulated (Schwarz’s dime
on the photocopier)
• But correlate well with proxies of well-being.
• People are not good at recalling their own
experiences.
33
Does subjective well-being mean anything (3)
Concern:
If happiness and life satisfaction became the
policy maximand, one effective intervention
might be to dampen peoples’ expectations; or
give out happiness pills.
Reality:
People care about the causes and processes of
higher/lower life satisfaction.
34
What is “experienced utility”?
• “Experienced utility”: an economists’
interpretation of life satisfaction and happiness
– a mental state account
– the level of utility that is actually felt
• cf. “decision utility” (preference satisfaction)
– the level of utility that people think they will feel
– utility inferred from observed choices
• People often mis-want, or get it wrong.
• So that satisfying preferences won’t bring
35
well-being
Why people mis-want
• Impact bias: overestimate impact
– Focalism (too much attention to the central event)
– Immune neglect (rationalise bad events)
• Projection bias: different arousal states (don’t
shop when hungry)
• Distinction bias: joint/single evaluations
• Memory bias: peak-end rule
• Duration neglect
36
Measuring experienced utility (1-1)
Experience sampling method (ESM)
• Participants carry palm top instrument.
• Random selection of times of day as
participant goes about daily life.
• Rating of various feelings such as “happy” or
“frustrated/annoyed”.
• Record what they are doing.
• Aggregate each ‘moment’ to obtain time
profile of affect.
37
Measuring experienced utility (1-2)
Advantages of ESM
• Real, experienced utility, as life events are
lived.
• No bias and distortion due to recall
Disadvantages of ESM
• Costly
• Possibly disruptive (eg. while driving)
38
Measuring experienced utility (2-1)
Day reconstruction method (DRM)
• Reconstruct previous day into a series of
episodes
• Where, doing what, with whom
• Rating of various feelings such as “happy” or
“frustrated/annoyed”.
• U-index: proportion of time in negative
emotion.
39
Measuring Well-being: The Day
Reconstruction Method
Respondents reconstruct the previous day:
like a retrospective TIME USE DIARY
Day is split into a sequence of episodes.
Respondents report the key features of each
episode, including
(1) When the episode began and ended
(2) What they were doing
(3) Where they were
(4) Whom they were interacting with, and
(5) how they felt on multiple affect dimensions
For each of the episodes that individuals identify during the
day, they are asked the following questions:
Measuring experienced utility (2-2)
Advantages of DRM
• Less costly than ESM
• Does not rely on participant self perception of
life domain
Disadvantages of DRM
• Element of recall: possible bias
– ie. it’s not how people felt then and there

46
Issues with Measuring Satisfaction
Social Desirability
Possible bias if we ask individuals sensitive questions: they want to
look good in front of the interviewer.
“computer-assisted self-interviewing (CASI) and self-completion
(SC) paper questionnaires are generally preferred to face-to-face
interviewing as a way of assuring a greater degree of
confidentiality and inducing more truthful responses”
This is why the GHQ questions discussed above are a drop-off
questionnaire. Self-reporting means that individuals are more
likely to report their true response to questions like
“have you recently been thinking of yourself as worthless”
47
Some BHPS results, from Conti, G., and Pudney, S. (2011). "Survey
design and the analysis of satisfaction". Review of Economics and
Statistics, 93, 1087-1093.
• Oral interviews conducted by an interviewer tend to produce more
positive reports of satisfaction than private self-completion
questionnaires – the “let’s put on a good show for the interviewer”
effect.
• When children are present during the interview, adult interviewees
tend to give still more positive responses – the “not in front of the
children” effect.
• The presence of the interviewee’s partner during the interview
tends to depress the level of reported satisfaction – the “don’t show
your partner how satisfied you are” effect, which we speculate
may have something to do with the desire to maintain a strong
bargaining position within the relationship.
48
Issues with Measuring Satisfaction
Which response scale?
Even if the question is a good one, on what scale would we
want them to respond?
A satisfaction question can be answered on a three-point
scale, a four-point scale, etc.
May want an odd number of response categories in order
for there to be a natural neutral
49
We would like a scale to be both reliable and valid
Pretests for the European Social Survey suggested that reliability and validity
were higher using an 11-point scale compared to a four-point scale.
50
Labelling categories?
A small change can have large effects…
Job satisfaction labels in the BHPS changed from Wave 1 to Wave 2
Label for category one changed. In Wave 2 all seven categories were labelled, as
opposed to only three of them in Wave 1.
51
Could this have any effect? Compare the JS distributions in Waves 1, 2 and 3.
Huge rise in the use of response six, now that it is labelled. The only
three labelled responses in Wave 1 attracted “too many” responses.
This particularly seemed to affect women
52
Is Happiness Everything?
Do questions about happiness and satisfaction
pick up everything that is important about
individual lives?
Or could there be “non-happiness” elements
that are important too?
Maslow’s Hierarchy of Needs
54
This is relevant in the context of the debate over hedonia
vs. eudaimonia.
Eudaimonia refers to the idea of flourishing or
developing human potential, as opposed to pleasure, and
is designed to capture elements such as mastery,
relations with others, self-acceptance and purpose.
Practically, eudaimonic well-being is measured by
questions on autonomy, determination, interest and
engagement, aspirations and motivation, and a sense of
meaning, direction or purpose in life.
Arguably picked up by last of the four ONS questions.

ONS Happiness Survey Questions Revealed
After becoming Conservative leader in 2005, David Cameron said gauging
people's feelings was one of the "central political issues of our time".
"It's time we admitted that there's more to life than money and it's time we
focused not just on GDP but on GWB - general well-being," he said.
The ONS will add the subjective questions to its next annual Integrated
Household Survey
The questions will include:
Overall, how satisfied are you with your life nowadays?
Overall, how happy did you feel yesterday?
Overall, how anxious did you feel yesterday?
Overall, to what extent do you feel the things you do in your life are
worthwhile?
www.bbc.co.uk/news/uk-12566965
Here is a measure of flourishing, based on Huppert
and So (2009).
All of these six questions on the right were asked
in Wave 3 of the European Social Survey
The first two of these are defined by Huppert and So as “core
features”, in that someone who is flourishing has to agree with
these statements. The measure they propose of flourishing is thus
agreement with the first two questions, plus agreement with at
least three of the next four questions.
Fifty six percent of the ESS sample is flourishing according to this
definition.
The second measure we appeal to is based on the New Economics
Foundation (2008), and measures i) Vitality, ii) Resilience and
Self-Esteem, iii) Positive Functioning, Supportive Relationships,
And Trust and Belonging.
Each of these three is constructed as the unweighted sum of the
answers to a number of z-score transformed questions (such that
each of the questions has a mean of zero and a variance of one).
Vitality consists of answers to questions on how
much of the time during the past week the
individual felt tired, felt that everything they
did was an effort, could not get going, had
restless sleep, had a lot of energy, and felt
rested when they woke up in the morning,
plus the respondent's general health and
whether their life involves a lot of physical
activity.
All of these are recoded so that higher values
reflect greater vitality.
Similarly, resilience and self-esteem is given the sum
of the answers to the four following z-score
transformed questions:
• "In general I feel very positive about myself“
• "At times I feel as if I am a failure“
• "I’m always optimistic about my future“
• "When things go wrong in my life, it generally takes
me a long time to get back to normal".
Again, all of these are recoded so that higher numbers
reflect greater resilience.
Last, positive functioning is determined by the answers to the
following questions:
•
"In my daily life I get very little chance to show how capable
I am“
•
"Most days I feel a sense of accomplishment from what I do“
•
"In my daily life, I seldom have time to do the things I really
enjoy“
•
"I feel I am free to decide how to live my life“
•
"How much of the time during the past week have you felt
bored?“
•
"How much of the time during the past week have you been
absorbed in what you were doing“
•
"To what extent do you get a chance to learn new things?“
•
"To what extent do you feel that you get the recognition you
deserve for what you do?“
•
"I generally feel that what I do in my life is valuable and
worthwhile"
These eudaimonia scores end up being pretty
closely correlated with the hedonic measures of
happiness and satisfaction (both 0-10).
Someone with high life satisfaction or happiness is fairly
likely to also be flourishing, have vitality, resilience and
functioning as well.
A second simple way of evaluating the difference, if any,
between hedonic and eudaimonic measures of well-being is to
carry out a regression analysis using "standard" sociodemographic variables as controls.
Here’s the regression table, just to prove that we did it….

Are the data patterns in these regressions the same?
The measures of happiness and life satisfaction
produce extremely similar data shapes. Some say
that satisfaction is more cognitive, but we don’t
see that here.
The correlation between the hedonic measures and
the eudaimonic measures, in terms of how they
fit the observable explanatory variables, is
reasonably high.
There is, however, one exception, with respect to
resilience. This concept does not seem to be
particularly closely related to either happiness or
satisfaction, which is perhaps a finding that is
worthy of future investigation
The same approach is taken by Helliwell (2012), comparing life satisfaction to the
Cantril ladder in Gallup World Poll data.
The Cantril Self-Anchoring Striving Scale (Cantril, 1965) has been included in
several Gallup research initiatives, including the Gallup World Poll of more
than 150 countries, representing more than 98% of the world's population.
The Cantril Self-Anchoring Scale, developed by pioneering social researcher Dr.
Hadley Cantril, consists of the following:
Please imagine a ladder with steps numbered from zero at the bottom to 10 at the
top.
The top of the ladder represents the best possible life for you and the bottom of the
ladder represents the worst possible life for you.
On which step of the ladder would you say you personally feel you stand at this
time? (ladder-present)
On which step do you think you will stand about five years from now? (ladderfuture)
The country-by-country rankings for life
satisfaction in the Gallup World Poll are very
similar to those for the Cantril ladder.
The correlation between the country rankings for
life satisfaction and the Gallup ladder responses asked of the same respondents, and in the same
survey - is very high (r=0.935). Analysis of the
resulting data show that while there were
significant differences in average scores, with
the mean of life satisfaction being higher by
about 0.5 on the 11-point scale, the two
variables are explained by the same factors,
including the same effects of income .
We can do something of the same thing in the
BHPS, looking at the correlation between life
satisfaction and GHQ regressions.
The Pearson correlation between the two sets of
estimated regression coefficients (of which there
are 48) is 0.775.
In other words, the “same kinds of things” are
correlated with both life satisfaction and GHQ.
Equally, in the BHPS, the pattern of adaptation
seems to be very similar between life satisfaction
and GHQ.
Slight suggestion that
children might do more for
you in terms of GHQ than in
terms of life satisfaction.
Which well-being measure better predicts
behaviour?: Benjamin et al. (2012),
“What Do You Think Would Make You
Happier? What Do You Think You
Would Choose?”, American Economic
Review.
They consider a series of sequence of
hypothetical pairwise-choice scenarios.
Regress hypothetical choice on predicted SWB (how happy you
think it will make you) and eleven non-SWB aspects of life:
•
•
•
•
•
•
•
•
•
•
•
Family happiness
Health
Life's level of romance
Social life
Control over your life
Life's level of spirituality
Life's level of fun
Social status
Life's non-boringness
Physical comfort
Sense of purpose
As shown by the R2, 0.38 of the variation in choice is
explained by SWB (own happiness) alone.
Regressing choice on both SWB and the eleven nonSWB aspects yields a barely higher R2 of 0.41.
But:“the four scenarios we designed to be
representative of typical important decisions facing
our college-age Cornell sample…socialize versus
sleep, family versus money, education versus social
life, and interest versus career… are among the
scenarios with the lowest univariate R2 and,
correspondingly, the highest incremental R2 from
adding non-SWB aspects as regressors”
Eudaimonia may then matter much more in certain reallife situations
Wave 2 of ELSA took place in 2004/5.
This covers individuals aged 50 or over.
We can model deaths by Wave 5 in 2010/11, six years
later.
Which measures of well-being at Wave 2 best predict
death by Wave 5?
This is work by Andrew Steptoe and colleagues at UCL,
