  1. Population Aging, Intergenerational Transfers, and the Economy: Introducing Age into National Accounts Andrew Mason University of Hawaii – Manoa East-West Center National Transfer Accounts

  2. Motivation • Three features of the economy • Economic lifecycle • Population age structure • Systems for shifting resources across age • Saving • Public transfer programs • Familial Support systems • Interaction influences economic performance and generational equity • Implications for economic and population policy National Transfer Accounts

  3. Organization • Fundamental Ideas • Brief Review of Recent Research • Current Effort: National Transfer Accounts • Basic Concepts • Three Important Issues National Transfer Accounts

  4. FundamentalsThe Economic Lifecycle Labor Income Consumption Note: Based on estimates for Costa Rica, Indonesia, Taiwan, and Thailand. National Transfer Accounts

  5. A Simple Model • Consumption-Loan Economy (Samuelson 1958) • Labor income only • All output is immediately consumed • Age reallocation system: Transfers only; no saving • Per capita age profiles of consumption and production are fixed (preceding slide) • Population age structure varies • Young: US 1850 • Middle-aged: India 2040 • Old: Japan 2050 National Transfer Accounts

  6. Aggregate C and YLVery Young Population (US 1850) National Transfer Accounts

  7. Aggregate C and YLVery Young Population (US 1850) National Transfer Accounts

  8. Aggregate C and YLLarge Working-age Pop (India 2040) National Transfer Accounts

  9. Aggregate C and YLOld Population (Japan 2080) National Transfer Accounts

  10. First Demographic DividendEconomic Support Ratio Ratio of effective workers to effective consumers National Transfer Accounts Source: Mason 2007.

  11. Summary of Implications • Changes in the relative numbers of workers and consumers over the demographic transition leads to a demographic dividend. • Bloom and Williamson • Bloom, Canning, and Sevilla • Lee and Mason • The effect erodes as populations age. National Transfer Accounts

  12. Introduce Capital to the Economic Model • Economy with capital • Workers save during their working years • Rely on asset income and dis-saving during retirement. • For solving the old-age lifecycle problem, capital and transfers are close substitutes. • However, capital also has favorable effects on economic growth. National Transfer Accounts

  13. What determines the lifecycle demand for capital? • Features of the economic lifecycle • Consumption by the elderly (now & future) • Labor income of the elderly (now & future) • Relative number of elderly: More elderly implies greater demand for lifecycle capital. National Transfer Accounts

  14. Demand for WealthOld versus Young Population Young Population Old Population Yl Yl C C LC demand for wealth is negligible LC demand for wealth is large Note: Uses per capita consumption profiles shown above. National Transfer Accounts

  15. What determines the lifecycle demand for capital (continued)? • Support system for the elderly • Public transfers • Familial transfers • Lifecycle saving • Public and familial transfers may crowd out lifecycle saving National Transfer Accounts

  16. II. Summary of Recent Research • Population, Saving, and Wealth • Changes in age structure are partially responsible for high saving rates in Asia (LMM various; KM 2007). • Longer life expectancy led to behavioral change that reinforced age structure effects (LMM various; KM 2007). • A decline in familial support for the elderly may have played an important role (LMM 2003). • Longer life expectancy and aging are leading to a permanent increase in wealth (LMM various; KM 2007) National Transfer Accounts

  17. II. Summary of Recent Research • Demographic Dividends • Changes in age structure produce two demographic dividends • First dividend • Concentration of population in working ages leads to more rapid economic growth; • Effect unwinds as populations age. • Second dividend: changes in age structure and increase in life expectancy lead to • More investment and more rapid economic growth • Permanently higher standards of living. Sources: Mason and Lee, various; Mason, various. National Transfer Accounts

  18. Important Issues to be Explored • How does the economic lifecycle vary and why? • What systems do societies use to shift resources from surplus to deficit ages? • Why do the systems vary across countries and evolve over time? • What are the implications for economic performance? For generational equity? • What are the implications for economic policy? For population policy? National Transfer Accounts

  19. III. National Transfer Accounts • Objective: • Develop and apply a comprehensive system of accounts that measures economic flows across age groups in a manner consistent with the System of National Accounts. • Conceptual foundation: • Lee (1994) but also Samuelson (1958), Diamond (1965), and Willis (1988). • Organization: • Collaboration between EWC/UH and UC-Berkeley. Core funding from NIA. Sub-projects supported by UNFPA, IDRC, MacArthur Foundation and others. • Website: www.ntaccounts.org National Transfer Accounts

  20. Participating Countries National Transfer Accounts

  21. Labor Income Consumption Source: Ogawa et al. 2007. National Transfer Accounts

  22. National Transfer Accounts

  23. Governments Families Charitable Organizations National Transfer Accounts

  24. Accumulation and dis-accumulation of debt Accumulation and dis-accumulation of assets National Transfer Accounts

  25. Inflows Labor Income Asset Income Transfer Inflows Outflows Consumption Saving Transfer Outflows The Flow Account Identity National Transfer Accounts

  26. Flow Account Details • Consumption: public and private for health, education, housing, and other. • Public transfers: in-kind (health, education, other) and cash (pensions and other). • Private transfers: intra-household for health, education, housing, and all other; inter-household for other. • Asset-based reallocations: Public and private investment; public and private credit/debt. • Flows to ROW: remittances, foreign investment, foreign aid. National Transfer Accounts

  27. Approach to Estimation • National Income Accounts and other aggregate statistics are used as aggregate controls • Age profiles are estimated using nationally representative surveys, e.g., income and expenditure surveys, labor force surveys, health expenditure surveys, etc. • Common methodology documented on www.ntaccounts.org National Transfer Accounts

  28. Issue 1: Lifecycle Deficit, Children • Does the lifecycle deficit per child increase as the number of children declines? • Becker quality-quantity tradeoff • If so, the decline in fertility will have a smaller effect on capital accumulation. • However, if consumption is higher because parents are spending more on education, then human capital will increase as the number of children declines.

  35. Issue 3. Support Systems for the Elderly. • How do they differ across countries? • Do Asian countries rely more on familial transfers and Western and Latin American countries more on public transfers? • Does the expansion of public systems crowd saving as hypothesized by Feldstein? • Or familial transfers? National Transfer Accounts

  36. Old-Age Reallocation Systems Saving Capital-based transformation Social welfare transformation Traditional society? Familial Transfers Public Transfers National Transfer Accounts

  37. Old-Age Reallocation Systems Saving Public transfers and familial transfers are substitutes (Barro). Familial Transfers Public Transfers National Transfer Accounts

  38. Old-Age Reallocation Systems Saving Public transfers to the elderly crowd out saving (Feldstein). Familial Transfers Public Transfers National Transfer Accounts

  39. Reallocations as a share of lifecycle deficit of the elderly. National Transfer Accounts

  40. Net public transfers downward Reallocations as a share of lifecycle deficit of the elderly. National Transfer Accounts

  41. Net family transfers downward Net public transfers downward Reallocations as a share of lifecycle deficit of the elderly. National Transfer Accounts

  43. Combined net transfer downward Reallocations as a share of lifecycle deficit of the elderly. National Transfer Accounts

  44. Familial transfers equally important in Thailand, Korea, and Taiwan (36-40%). Net familial transfers near zero in US, CR, and J. Large public transfers in CR and J. More reliance on assets in CR & US. Net public transfers to elderly are zero in Thailand; about 25% in Taiwan and Korea. National Transfer Accounts

  45. Reliance on assets in old-age National Transfer Accounts

  46. 65-year-olds 67% assets, 2% public, 32% private 85-year-olds 23% assets, 39% public, 38% private National Transfer Accounts

  49. From ages 65 to 80, familial share varies little. Public rising and asset-based declining. After 80 familial share is rising and asset-based declining. National Transfer Accounts

  50. Asset-based reallocations and public transfers have increased over time; familial transfers have declined precipitously. NHI began in 1995; net public transfers increased. National Transfer Accounts
