Three Essays On Fertility Rates In China, Lichun Cai

Dissertations

China is currently facing the issue of low fertility rates. In three chapters, I discuss the reasons for the low fertility rate in China from three different microeconomics perspectives, by using econometric methods including machine learning tools.

Chapter One considers the effects of income on fertility rate. There is a widely accepted view that the improvement of the education level has led to a decline in fertility. I critique this view and propose a new perspective: the childbirth choice of a family member is not only related to the education level, but also to the differences in education level between …
