Mortality Reductions, Educational Attainment, and Fertility Choice

Area of Science:

• Economic History
• Demography
• Development Economics

Background:

• Historically, economic development and demographic changes are intertwined.
• Understanding the causal relationship between mortality, fertility, and economic growth is crucial for policy.
• The Malthusian trap describes a state of economic stagnation due to population growth outstripping resources.

Purpose of the Study:

• To model the impact of mortality reductions on economic development.
• To analyze the sequence of changes mirroring the demographic transition.
• To identify the critical threshold for economic transformation.

Main Methods:

• Development of an economic model incorporating mortality, fertility, and human capital.
• Simulation of demographic and economic transitions within the model.
• Analysis of equilibrium shifts from Malthusian to human capital-driven growth.

Main Results:

• The model demonstrates that declining mortality precedes reductions in fertility and increases in human capital accumulation.
• A critical level of life expectancy at birth is identified as the trigger for this transition.
• The model supports a shift from a Malthusian equilibrium to one characterized by sustained economic growth.

Conclusions:

• Reductions in mortality are a primary driver of economic development.
• The demographic transition is a key mechanism linking health improvements to economic progress.
• Achieving a critical life expectancy threshold unlocks sustained economic growth through human capital investment.
