  1. Economic Growth and Subjective Well-Being:Reassessing the Easterlin Paradox Betsey Stevenson and Justin Wolfers Wharton School, University of Pennsylvania and NBER The 2008 World Congress on NAEP Measures for Nations, May 14 2008.

  2. Research Question: What is the relationship between income & happiness? Why revisit the stylized facts? • Theoretical implications: Reference-dependent preferences • Yielding important policy implications (and big policy claims) • New data: Longer time series (1946-2008); More countries (n=132) • Statistical inference: Absence of evidence v. evidence of absence • 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” Stevenson & Wolfers, Economic Growth and Happiness

  3. Measuring Subjective Well-Being • Subjective well-being 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].” • Creating a cardinal measure • Macro data: Two steps • Estimate “Gross national happinessc,t”Ordered probit: Happinessi,c,t = μc,t * I(country)*I(year) + ε ε~N(0,1) • Regress GNH on GDP: μc,t = β log(Incomec,t ) + ν • Micro data: • Ordered probit: Happinessi,c,t = β log(Incomeindividual country or period )+ ε ε~N(0,1) Stevenson & Wolfers, Economic Growth and Happiness

  4. Outline: Assessing the Happiness-Income link • Within-country comparisons • USA • All countries • Between countries: • Through time • Multiple datasets • For both happiness and life satisfaction • No evidence of satiation • National Time Series • Japan • Europe • USA Stevenson & Wolfers, Economic Growth and Happiness

  5. Within-Country Comparisons “Taken all together, how would you say things are these days?” Source: U.S. General Social Survey, 2006 “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) Stevenson & Wolfers, Economic Growth and Happiness

Outline: Assessing the Happiness-Income link • Within-country comparisons • USA • All countries • Between countries: • Through time • Multiple datasets • Both happiness and life satisfaction • No evidence of satiation • National Time Series • Japan • Europe • USA βwithin ≈ 0.2 – 0.4 “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) Stevenson & Wolfers, Economic Growth and Happiness

  26. Recalled feelings and GDP Stevenson & Wolfers, Economic Growth and Happiness

  27. Bradburn: Recent Feelings and GDP Stevenson & Wolfers, Economic Growth and Happiness

  28. Within-Country: Rich are Happier than Poor • Similar relationship holds in other countries and eras • “As far as I am aware, in every representative national survey ever done a significant bivariate relationship between happiness and income has been found.” – Easterlin (2001) Question: “In general, how happy would you say that you are?” %Very happy rising with income %unhappy falling with income Stevenson & Wolfers, Economic Growth and Happiness

  29. Between-Country Estimates: Happiness & GNP Stevenson & Wolfers, Economic Growth and Happiness

  30. Time Series: No rise in happiness, despite growth Stevenson & Wolfers, Economic Growth and Happiness

  31. Implications of the Easterlin Paradox • “Why do national comparisons among countries and over time show an association between income and happiness which is so much weaker than, if not inconsistent with, that shown by within-country comparisons?” –Easterlin (1974) • Reference-dependent preferences • Relative income matters [Other people’s consumption matters] • Habit formation = hedonic treadmill [Other period’s consumption] • Policy implications: • Growth: “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.”–Easterlin (2005) • Public finance: If preferences are interdependent Pigouvian rationale for taxing labor supply / conspicuous consumption Stevenson & Wolfers, Economic Growth and Happiness

  32. Subjective Well-being • “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].” Stevenson & Wolfers, Economic Growth and Happiness

  33. Alternative measures of average happiness Stevenson & Wolfers, Economic Growth and Happiness

  34. Income-Happiness Relationship in GSS Stevenson & Wolfers, Economic Growth and Happiness

  35. Within-Country: Rich are happier than poor Notes: ***, ** and * denote statistically significant at 1%, 5% and 10%, respectively. (Robust standard errors in parentheses, clustered by country.) Column 1: An ordered probit regression of well-being on log household income, and country fixed-effects Column 2: Adds gender, a quartic in age, and their interaction as controls Column 3: Instruments for log household income using indicator variables for levels of education. Second stage is an ordered probit regression of well-being on the predicted values, the residuals, and country fixed-effects. Column 4: The instrument set now includes indicator variables for levels of education, interacted with country dummies. Stevenson & Wolfers, Economic Growth and Happiness

  36. Within-Country Variation: Gallup World Poll Stevenson & Wolfers, Economic Growth and Happiness

  37. Between-Country GDP-Wellbeing Gradient Stevenson & Wolfers, Economic Growth and Happiness

  38. Is there any evidence of satiation? • “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) • Rich countries (GDP>$15,000) • Happiness=1.08*log(GDP) [se=0.19] • Poor countries (GDP<$15,000) • Happiness=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 Stevenson & Wolfers, Economic Growth and Happiness
