In this chapter we revisit the relationship between income and fertility. There is overwhelming empirical evidence that … fertility is negatively related to income in most countries at most times. Several theories have been proposed in the literature …

In its original formulation, however, it has … not been very successful at reproducing the changes in fertility choice in response to decreased mortality and increased … intertemporal elasticity of substitution (IES) typically assumed in the fertility literature.

It is shown that under reasonable parameter values …, fertility is pro-cyclical and that, following a shock, fertility continues to cycle endogenously as subsequent cohorts enter …
