Subjective Well-Being, Income, Economic Development and Growth

Subjective Well-being
Sacks, Stevenson & Wolfers, Income and Happiness 3
“Subjective well-being refers to all of the various types of evaluations, both positive and negative, that people make of their lives. It includes reflective cognitive evaluations, such as life satisfaction and work satisfaction, interest and engagement, and affective reactions to life events, such as joy and sadness.” (Diener, 2005)
Typical questions: Happiness
“Taking all things together, would you say you are: very happy; quite happy; not very happy; not at all happy.”
Life satisfaction“All things considered, how satisfied are you with your life as a whole these days?” [1=Dissatisfied – 10=Satisfied]
Satisfaction ladder: “Here is a ladder representing the ‘ladder of life’. Let's suppose the top of the ladder represents the best possible life for you, and the bottom, the worse possible life for you. On which step of the ladder do you feel you personally stand at the present time? [0-10 steps].”
Research Question: What is the Relationship Between Subjective Well-being and Income?
Sacks, Stevenson & Wolfers, Income and Happiness 4
Types of comparisons 1970s view“Easterlin Paradox”
1990s view“Satiation”
New view: Stevenson-Wolfers findings
Within country:Rich v. poor people in a country
Big effects Big effects for income <$15k
- But not for the rich
Strong effects: βwithin≈0.35
Between country:Rich v. poor countries
Statistically insignificant effects
interpreted to be zero
GDP<$15k:Strong effects
GDP>$15k: No effects
Strong effectsβbetween=0.35
National time series:Country when rich v. poor
No effects(Japan, USA, Europe)
No effects(Available data are for
rich countries)
Strong effectsβtime series=0.35
International panel:Countries with fast v. slow growth
Largely unexamined Largely unexamined Strong effectsβpanel=0.35
Implications Relative income determines well-
being
Relative income determines well-
being… once “basic needs” are met”
There’s no paradox(and never was)
Policy conclusions De-emphasize growth
Rich countries should de-emphasize growth and tax labor supply
“My results, along with mounting evidence from other time series studies of subjective well-being, do on balance undermine the view that a focus on economic growth is in the best interests of society.” – Richard Easterlin (2005)

Why revisit the stylized facts?
1. Theoretical implications: Reference-dependent preferences
2. Yielding important policy implications (and big policy claims)
What explains our new findings?1. New data:
Longer time series (1946-2010); More countries (n=140)
2. Statistical inference: Absence of evidence v. evidence of absence
3. What are “big” versus small effects? Focus on the magnitudes
What we won’t do Assess causality: Happiness = β log(Income) Revisit what subjective well-being data “mean”

“Taken all together, how would you say things are these days?”
“When we plot average happiness versus income for clusters of people in a given country at a given time, we see that rich people are in fact much happier than poor people. It’s actually an astonishingly large difference. There’s no one single change you can imagine that would make your life improve on the happiness scale as much as to move from the bottom 5 percent on the income scale to the top 5 percent.”
- Robert Frank (2005)

Notes: The table reports the coefficient on the log of household income, obtained from regressing standardized life satisfaction against the log of household income and country fixed effects using the indicated data set. Additional controls include a quartic in age, interacted with sex, plus indicators for age and sex missing. Our permanent income adjustment is to scale up our estimates by 1/0.55; see text for explanation. We instrument for income using full set of country×education fixed effects. We report robust standard errors, clustered at the country level, in parentheses. For further details on the standardization of satisfaction and the exact wording of satisfaction question, see the text. ***, ** and * denote statistically significant at 1%, 5% and 10%, respectively.

“the happiness differences between rich and poor countries that one might expect on the basis of the within country differences by economic status are not borne out by the international data.” – Easterlin, (1974)

“income growth in a society does not increase happiness”. - Easterlin (1995)
Happiness & Economic Growth: Time Series Evidence Japan
Old view: Life satisfaction flat, despite robust post-war growth New view: Robust growth in life satisfaction
…apparent only when taking account of breaks in the data US
Old view: No increase in happiness since 1972 despite GDP growth New view: True.
…but few sample participants experienced income growth Europe
Old view: No clear evidence of growing life satisfaction (1973-89) New view: Extending data through 2007 yields clearly rising satisfaction
Around the World Old view: No clear evidence of growing life satisfaction New view: Clear positive relationship between income and growth
… when comparing comparable samples

Is there any evidence of satiation?
Sacks, Stevenson and Wolfers, Subjective Well-Being 34
Rich countries (GDP>$15,000) Satisfaction=1.08*log(GDP) [se=0.21]
Poor countries (GDP<$15,000) Satisfaction=0.35*log(GDP) [se=0.04]
A 1% rise in GDP: Has three times larger effects in rich countries than poor
countries A $100 rise in GDP
3x larger effect in Jamaica than US 20x larger effect in Burundi than US
“if we compare countries, there is no evidence that richer countries are happier than poorer ones – so long as we confine ourselves to countries with incomes over $15,000 per head.” - Layard (2005)

Research Question
Does inequality undermine average levels of subjective well-being?
Surprisingly mixed findings: “The presumed link between equality and happiness fails to appear, at least where
income inequality is concerned. Average happiness is as high in countries with great income inequality as in nations where income differences are small” –Veenhoven (2000)
Including inequality in our regressions using the available data, we find that is has a negative effect, although its’ size and significance levels are both low. –Di Tella and MacCulloch (2008)
“In the whole World Values Survey sample, the Gini coefficient has a positive (albeit not always significant) effect on life satisfaction.”—Guriev and Zhuravskaya (JEP 2008, p.157)
“Adding a World Bank estimate of the Gini coefficient for each national economy added no explanatory power to the well-being equation.”—Helliwell (2003)
