Labor Income
Consumption
• Based on per capita profile for developing countries weighted by UN estimates of 2005 age structure.
• Two features are of interest
• Overall dependency: Total difference between labor income and consumption.
• Direction of IG flows: Do flows to children or the elderly dominate?
Research Questions about the Economic Lifecycle Will change in age structure lead to demographic
dividend? Are the dividends sustainable? What policies are needed?
Will fertility decline lead to a decline in spending on children and, in particular, their human capital? Quantity-quality tradeoff: Becker Political economy arguments: Preston
Can the finance of health care and long term care be improved?
Can policies raise the labor production by the elderly? Age at retirement: Gruber and Wise Productivity of older workers:

Other Sources of Funding Consumption (Reallocation System) Familial Transfers Asset-based Reallocations
Interest, dividends, rent from personal assets Home and other consumer durables Dis-saving
Public Transfers Social Security System
7
Research Questions about the Reallocation Systems How do reallocation systems vary across
countries and over time? What is the impact of policies that expand or
contract public transfers to the elderly? Crowd out private transfers? If so, does this effect
fertility? Crowd out saving and thereby reduce economic
growth? Can we “stress test” reallocation systems?

The NTA Projects…
Develop a system of economic accounts that can be used to study the macroeconomic implications of change in age structure.
Estimate the accounts with historical depth for economies with different cultures, levels of development, economic systems and policies.
Analyze and explain variation in the economic lifecycle and the reallocation
systems, macroeconomic effects of population aging, economic implications of pension, health care, education,
child subsidies, and other policy. Led by Ron Lee and Andrew Mason.
Currently 24 country teams are participating.

Important Features of the NTA Comprehensive approach:
All mechanisms for shifting resources from one age group to another are incorporated into the accounts.
Both public and private institutions are incorporated. The role of the family is emphasized.
NTA is consistent with and complementary to National Income and Product Accounts.

22
The Second Demographic Dividend Population aging can lead to an accumulation of
wealth to meet pension needs for retirement.
If workers save more (relying on asset-based reallocations) in anticipation of aging, higher income is possible even after the first dividend period has come to an end.
Alternatively, workers can rely on transfer wealth (PAYGO pension programs, familial transfer), which has little effect on growth (in our model, we assume that the % of transfer wealth is fixed).

2nd dividend
2nd dividend weak in simulation because of low consumption
among elderly.
24
Some Remarks
The gains from relying heavily on asset-based reallocations are realized in the form of higher assets with small gains in consumption.
Later in the simulation (not shown), gains in consumption are substantially higher with smaller reliance on transfer programs to support the elderly. For example, using the medium scenario per capita
consumption is higher in 2100 by 14% for tau=0.35 than tau=0.6.
25
Policy Implications
Good policies that are consistent with poverty reduction goals that do NOT undermine work and saving incentives, and
promote growth and that are financially sustainable.
One set of policy implications are economic policy that can best accommodate population
policy Influencing population change and age structure, per se.
26
Conclusions Population matters
Population size and age structure Policy matters
Implication for growth; but underdeveloped financial markets may limit investment opportunities.
Early policy response is essential to realize the demographic dividend.
