Life expectancy does not affect all countries the Life expectancy does not affect all countries the same way.
Its impact depends on whether a country is before or after the demographic transition.
The demographic transition is the historical shift from:
High mortality & high fertility → Low mortality & low fertility
This shift completely changes how population, education, and income respond to improved life expectancy.
🧠 CORE IDEA (The Big Discovery)
Life expectancy can both increase and decrease economic growth — depending on the stage of development.
⭐ Before the demographic transition (pre-transitional countries):
Lower mortality → population grows faster
Fertility remains high
Little investment in education
Result: Population growth reduces per-capita income
📉 Life expectancy hurts economic growth in early-stage countries
Life Expectancy and Economic Gr…
⭐ After the demographic transition (post-transitional countries):
Lower mortality → population growth slows down
Families invest more in education (human capital rises)
Economic productivity increases
Result: Per-capita income grows faster
📈 Life expectancy boosts economic growth in advanced-stage countries
Life Expectancy and Economic Gr…
🔥 Ultimate Insight
Improving life expectancy is actually a trigger for the demographic transition itself.
This means:
When life expectancy becomes high enough, a country begins shifting from high fertility to low fertility.
This shift is what unlocks sustained long-run economic growth.
📌 The paper finds strong evidence:
Higher life expectancy significantly increases the probability of undergoing the demographic transition.

📊 How It Works – Mechanism Explained
1. Pre-Transition Phase (Low Development)
Mortality falls, people live longer
But fertility stays high → population explodes
More people sharing limited land/capital → income per capita drops
Education gains are small

2. Transition Phase (Around 1970 for many countries)
Fertility begins to fall
Population growth slows
Human capital investment begins to rise
Life Expectancy and Economic Gr…
3. Post-Transition Phase (High Development)
Longer lives → people invest more in education
Human capital grows
Smaller families → more resources per child
Income per capita increases strongly

🔍 Evidence From the Paper
Based on data from 47 countries (1940–2000):
✔ In pre-transitional countries:
Life expectancy increase → higher population, lower income per capita
Life Expectancy and Economic Gr…
✔ In post-transitional countries:
Life expectancy increase → lower population growth, higher income per capita, higher education levels
Life Expectancy and Economic Gr…
✔ By 2000:
Life expectancy had strong positive effects on schooling in all countries

🧩 Why Earlier Research Was Conflicting
Previous studies found:
Sometimes life expectancy increases GDP
Sometimes it decreases it
This paper explains why:
👉 The effect depends on whether the country has undergone the demographic transition.
If you mix pre- and post-transition countries, the results get confused.

🏁 Perfect One-Sentence Summary
Improvements in life expectancy can slow economic growth in early-stage countries by accelerating population growth but strongly boost growth in advanced countries by reducing fertility, raising education, and triggering the demographic transition.... |
