Demographic transition and fertility rebound in economic development

Recent evidence on the ‘fertility rebound’ offers credence to the idea that, from the onset of early industrialisation to the present day, the dynamics of fertility can be represented by an N-shaped curve. An overlapping generations model with parental investment in human capital can account for these observed movements in fertility rates during the different stages of demographic change. A demographic transition with declining fertility emerges at the intermediate stage, when parents engage on a child quantity quality trade-off. At later stages however, the process of economic growth generates sufficient resources so that households can rear more children while still providing the desirable amount of education investment per child.
