2. New Estimates of the Index of Economic Well- Being for Canada Lars Osberg - Dalhousie University Andrew Sharpe - Center for the Study of Living Standards Canadian Economics Association May 27, 2006

3. "Are you better off today than you were four years ago?" 1980 Ronald Reagan 1976-80 actual increase in per capita disposable income in USA = 8.8% Audiences answered “NO!” – WHY ? Widespread dissatisfaction with GDP as a measure of Economic Well-Being BUT: Alternative measures also aggregate to a single index, burying value judgments

4. Is the nation “better off” ? As voters or bureaucrats, individuals do make decisions re: collectivity Vote index I = α 1 (own utility) + α 2 (society’s well-being) Economic Well-Being is multi-dimensional Index should respect heterogeneity Values / Preferences of Analysts Life Circumstances of Population Objective of Index construction: to assist democratic discourse & summative subjective judgments

5. Outline of Paper Index of Economic Well Being Consumption flows Sustainability / Accumulation of Productive Resources Distribution: inequality & poverty Economic Security Present new estimates of trends in the index for Canada and provinces Compare to GDP per capita trends Discuss methodological changes Linear Scaling Economic Security from Risk of Unemployment

6. Dimensions of Economic Well Being ConceptPresent Representative Agent / “Typical Citizen” Average Flow of Current Income Per Capita GDP or “Adjusted” Average Income Flow Issues: Market transactions only, heterogeneity, stocks

7. Dimensions of Economic Well Being ConceptPresent Representative Agent / “Typical Citizen” Average Flow of Current Income Diversity of Population Experiences Distribution of Current Income - Poverty and Inequality Social Welfare Function literature SWF = f ( µ, σ )

8. Dimensions of Economic Well Being ConceptPresentFuture Representative Agent / “Typical Citizen” Average Flow of Effective Current Consumption Aggregate Accumulation of Productive Stocks (broadly defined) Issues:Average Income does not reveal savings rate - assets include environment, Human Capital, R&D, etc. Aggregate Savings – not automatically optimal, sustainable –preferences for social saving differ among individuals

9. Dimensions of Economic Well Being ConceptPresentFuture Representative Agent Average Flow of Effective Current Consumption Aggregate Accumulation of Productive Stocks Diversity of Population Experiences Distribution of Current Income: - Poverty and Inequality Insecurity of Future Income

10. Values matter – and differ ECONOMIC WELL-BEING= α 1 [ CONSUMPTION ] + α 2 [ STOCKS OF WEALTH ] + α 3 [ EQUALITY ] + α 4 [ ECONOMIC SECURITY ] DIFFERENT VALUES WILL IMPLY DIFFERENT WEIGHTS Useful to know whether (& how much) aggregate trend depends on weighting α = 0 is a (strong) value choice

12. Why an Additively Separable Social Welfare Function ? Key theoretical assumptions: Constant relative risk/inequality aversion Imperfect Insurance & Capital Markets Additively Separable Lifetime Utility Risk Averse Representative Agent choosing from behind Veil of Ignorance ? Communication is key to actual usage Sensitivity to alternative weightings easy

13. Methodology Variables now scaled linearly Consistent with other indices (e.g. HDI) Solves “Directionality Problem” (Max – value)/(Max – Min) OR (Value – Min)/(Max-Min) Problems: Reporting trends as % change or % points Scaling removes base – sensitive to comparison group “Base Case” assigns equal weight to all dimensions Excel data sheet available for experimentation

15. Average Consumption Flows $ Marketed real consumption per capita from SNA Adjustments value of increased longevity of life / consumption reduced economies of scale in household consumption Unpaid work – @ generalist replacement wage Government services @ cost “Regrettable Necessities” Commuting, costs of crime & divorce, household pollution abatement spending

18. Accumulation, Sustainability and Intergenerational Bequest $ Physical capital stock Plant & Equipment + Residential Research and Development – as capital stock Value of natural resource stocks price + quantity change Stocks of human capital (@ cost education) Net change in foreign indebtedness Net Change in state of environment & national heritage (cost of CO 2 emissions ) NOTE: Real productive assets only

20. Distribution Same average income if all get $500 or if ½ get $999 & ½ get $1 – but well-being differs How to summarize “Distribution”? Simplicity desirable if index to be used Poverty & Inequality differ, but both matter Inequality - Gini coefficient After-tax & transfer household income Equivalence scale = Poverty - Sen-Shorrocks-Thon measure Rate (Poverty Line = ½ Median) Average poverty gap ratio Intensity = rate x gap

23. Economic Security. [25] “Everyone has the right to a standard of living adequate for the health and well being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.” Universal Declaration of Human Rights - United Nations: 1948 “Named Risks” – conditional probability of financial loss approach

24. “Economic Security” Risk of loss due to unemployment Risk of Unemployment + E(financial loss|unemployment) Financial Risk of Illness Unreimbursed private medical expenses as share of disposable income Risk of single parent poverty Divorce rate x poverty rate x poverty gap of single parents Risk of poverty in old age chance x depth of elderly (>65) poverty Security risks weighted by relevant population size

25. Security from Unemployment Original method – financial loss implied by compound probability =P(U)*P(B|U)*(E(B/W) Assumes components matter equally Decline UI/EI coverage has big impact on trends New literature on self-reported happiness Di Tella, MacCulloch, Oswald (2003) “The Macro Economics of Happiness” RESTAT Ordered Probit life satisfaction – n= 271,224 Recover Implicit weights on Unemployment Rate and Unemployment Benefits This paper: Unemployment rate = 4x UIBen =.8*(scaled Unemp) +.2*(scaled P(B|U)*(E(B/W))

31. Conclusion growth rate 1981 – 2005 GDP per capita = 1.68 % Index of Economic Well-being = 1.30 % Average Consumption flows & Wealth Stocks grew Equality & Security declined Equality & Security Focus of Welfare State Crucial to personal well-being
