The Evolution of Health Investment: Historical Motivations and Fertility Implications

In this working paper, I developed a suite of macroeconomic models that shed light on the intricate relationship between economic development, health, and fertility. These innovative models conceptualize health as an intermediate good, paving the way for new interpretations of dynamic socio-economic phenomena, particularly the non-monotonic effects of health on economic and population growth. The evolving dynamic interactions among economic growth, population, and health during the early stages of human development have been well interpreted in this research.
