Release Date: May 26, 2025

Introduction

In this episode of Tangle, host Isaac Saul engages in an insightful conversation with Emily Oster, a renowned author, economist, and expert on pregnancy and parenthood. The discussion delves into the declining birth rates, the factors influencing this trend, and the potential policy solutions to address it. Oster shares her expertise on the subject, providing data-driven perspectives and personal insights as a parent of two.

Understanding the Declining Birth Rates

Isaac Saul begins the conversation by addressing a pressing societal issue: the apparent decline in birth rates. He seeks Oster's expertise to understand whether this trend is accurate and explores the underlying reasons.

Emily Oster (06:23):
"Globally, fertility rates are on the decline everywhere. Every rich country now has a fertility rate below replacement, which is about 2.1 children per woman."

Oster explains that this decline isn't isolated to the United States but is a global phenomenon. She highlights that even in less developed countries, fertility rates have significantly decreased over the past few decades.

Impact of Financial Incentives on Birth Rates

Isaac brings up the idea of financial incentives, such as the proposed $5,000 payout or tax breaks, as potential solutions to boost birth rates. He references previous measures like the Child Tax Credit and compares them to initiatives in countries like Israel and South Korea.

Emily Oster (09:24):
"The evidence on financial payments for kids is mixed and not super encouraging as a game-changing solution. Larger incentives can prompt some increase in births, but the effects are not enormous."

Oster emphasizes that while substantial financial incentives can lead to a slight uptick in birth rates, they are unlikely to reverse the overall declining trend. She notes that these incentives may encourage earlier childbearing rather than increasing the total number of children.

Beyond Financial Factors: Cultural and Societal Shifts

The conversation shifts to exploring non-financial factors contributing to the declining birth rates. Isaac references feedback from listeners who argue that lower birth rates might be beneficial for environmental and resource management reasons.

Emily Oster (25:34):
"From an economic growth standpoint, dropping fertility rates are a potential issue. The structure of society will be very different with fewer kids and more elderly people."

Oster acknowledges the complexity of this issue, balancing the economic implications of a shrinking younger population against arguments that fewer births could positively impact environmental sustainability. She underscores the importance of supporting individual choice while recognizing broader societal challenges.

The Role of Family Support Policies

Isaac challenges Oster on the effectiveness of family support policies, seeking her perspective on why such measures might not be sufficient to address the decline in birth rates.

Emily Oster (17:44):
"In the US, we lack federal paid parental leave, which impacts women's ability to balance work and family. Providing better parental leave and childcare support can have practical benefits, including reduced healthcare costs and increased labor force participation among women."

Oster advocates for enhanced family support policies, such as paid parental leave and affordable childcare, arguing that these measures not only support families but also have economic benefits by enabling more women to remain active in the workforce.

Personal Reflections and Changing Parental Concerns

Isaac shares his personal experience as a new parent and how it has shaped his views on parental leave and family support.

Isaac Saul (20:20):
"After witnessing the challenges of parenting firsthand, I see the immense value in policies that support parents. It's not just about economics; it's about the wellbeing of families."

Oster concurs, highlighting the ethical and practical reasons for investing in family support systems. She points out that such policies can lead to healthier children and more stable families, ultimately benefiting society as a whole.

Responding to Public Perception and Debate

Towards the end of the conversation, Isaac discusses the varied public opinions on declining birth rates and how Oster addresses criticism from those who view lower fertility as advantageous.

Emily Oster (25:34):
"There's a philosophical and ethical debate around whether fewer people are better for society and the environment. Personally, I believe in encouraging choice and supporting those who decide to have children, recognizing that societal structures need to adapt to these changes."

Oster emphasizes the importance of respecting individual decisions regarding parenthood while advocating for policies that make it easier for those who choose to have children.

Conclusion

The episode provides a comprehensive analysis of the declining birth rates, combining economic data with personal insights. Emily Oster articulates the multifaceted nature of this issue, addressing both the challenges and the potential policy responses. Listeners gain a deeper understanding of the societal shifts affecting family planning and the importance of supportive measures to empower individuals in their parenting choices.
