Public Daycare Outperforms Cash in Boosting Japan's Birth Rates—But Both Are Essential
New research reveals public childcare + cash benefits can increases births, keeps mothers employed, and reduce the need for social security taxes—why policymakers can't afford to just pick one
New research in The Japanese Economic Review (Macroeconomic and welfare effects of family policy: cash transfers vs in-kind benefits by Reona Hagiwara from Waseda University) finds that while both public daycare and cash allowances boost birth rates and women's employment in Japan, in-kind benefits like daycare show stronger overall economic benefits when combined with targeted cash support.
Think of it like this: Japan needs immediate support for parents (through cash benefits) and long-term infrastructure (through childcare support) to address its demographic challenges. The research examines how these approaches perform when funded by a 1% consumption tax increase, showing their mechanics so we can figure out the best way to use the two policies together.
Quick take: The public daycare approach wins by:
Getting slightly more babies (2.17 vs 2.16 children per family)
Keeping way more moms working (3.8% vs 0.7% increase)
Cutting social security taxes more (2.0 vs 1.8 percentage points)
By the numbers
Birth rate impact:
Starting point: 2.03 children per family
With cash: Up to 2.16
With daycare: Up to 2.17
Economic ripple effects:
Social security taxes could drop from 29.4% to:
27.6% with cash benefits
27.4% with public daycare
Here's why: While each policy alone shows promise - cash benefits increase births by 6.2% and public daycare by 6.5% - they tackle different challenges facing potential parents. Both approaches help grow the working-age population by 0.9% and reduce the proportion of retirees (by 2.0-2.1%). Where they differ is their impact on current workforce participation. While both policies encourage men to work 1.7% more, public daycare drives a 3.8% jump in female employment compared to cash benefits' 0.7% increase. This suggests an optimal strategy: use public daycare to maximize workforce participation while maintaining targeted cash benefits to help families with direct costs. Together, they create a stronger effect - more workers contributing today and more babies becoming tomorrow's workforce - allowing the social security system to maintain benefits with lower tax rates. The key isn't choosing between policies but combining them strategically to support families across different income levels and life situations.
The tax burden drops most effectively when both policies work together!
Welfare improvements:
Single folks: ~2.2% better off with daycare vs ~1.8% with cash
Married couples: 4.8% improvement with daycare vs 4.1% with cash
The catch!: Parents invest about 2.4% less in each child's education when they have more kids - regardless of which policy is used.
Between the lines
Think of it as two different solutions for two different problems:
College-educated parents:
The main obstacle: Time management
Better solution: Public daycare
Why: They can afford kids but need help juggling work and family
Lower-income families:
The main obstacle: Basic expenses
Better solution: Cash benefits
Why: They need help with everyday costs
While both approaches help, public daycare creates a positive feedback loop:
Parents (especially moms) can keep working
More workers mean more tax revenue
More tax revenue means lower social security burden
Lower burden makes having kids more affordable
Repeat
The bottom line
While public daycare shows stronger economic returns, Hagiwara's research suggests Japan's optimal strategy combines both approaches: expanding public daycare to support workforce participation while maintaining cash benefits based on family needs. This dual approach addresses both immediate financial needs and long-term economic growth.
