ISSUE
• Widespread concern that low fertility and rapid population aging will lead to:– Severely strained public budgets– Reduced standards of living
• Governments of more than 50 countries reported to the UN that their birth rates were too low.
• Many governments are adopting programs to encourage couples to have more children.

Findings
• Moderately low birth rates, below replacement fertility, are actually ideal for achieving a high material standard of living.
• Fiscal problems can be addressed by: – Investing more, and more effectively, in human capital – Adjusting retirement ages and eligibility for public support
in response to the improved health of older adults – Adjusting public spending and tax systems as needed
• Only if birth rates are very low, should governments actively pursue pro-natalist policies.

• Determined the fertility rate the would produce an age structure allowing the highest age-specific benefits per tax dollar spent.

SRG summarizes the adjustments to taxes and/or spending required to maintain current balance between inflows and outflows.
Given age profiles of public transfer inflows and outflows and 2009 mortality schedule.
Best possible outcome • TFR of 2.7 and mean age
in the mid-30s• Spending cut of 16% or• Tax increase of 19%
Status quo outcome • TFR of 1.34 and mean age
in the mid-50s• Spending cut of 30% or• Tax increase of 45%
Current balance of taxes and spending is unsustainable

Moderately Low Fertility Is Best for Standards of Living
![Page 10: Is Low Fertility and Rapid Population Aging Really a Problem? 10 th Global Meeting of the National Transfer Accounts Network Beijing, November 14, 2014](https://reader035.vdocuments.us/reader035/viewer/2022062422/56649f1b5503460f94c30bb0/html5/thumbnails/10.jpg)

Evidence: Standards of Living
• Detailed estimates of public benefits received and taxes paid at every age in 29 economies.
• Detailed estimates of private costs and benefits at every age in 40 economies.
• Capital costs of a larger labor force.• Determined the fertility rate that would produce
an age structure allowing the highest level of consumption at every age.

Effect of TFR on Consumption(K/Y = 3, own mortality schedule)
Note: Average values for NTA economies using their current survival schedule and consumption and labor income profiles.
Very low birthrate of 1.3 births per
woman will reduce consumption by
about 7%.

Summary• Changes in age structure in recent decades have led
to a very favorable but transitory demographic dividend.
• Going forward, for any demographic scenario, major adjustments to the public sector will be required.
• In most countries, encouraging higher fertility is the wrong answer. It will lead to lower standards of living.
• In a few countries with VERY low fertility, pro-natalist policies should be explored.
