On Population Structure and Marriage Dynamics
Abstract
I develop an equilibrium, a two-sided search model of marriage with endogenous population
growth, to study the interaction between fertility, the age structure of the population
and the age of men and women at first marriage. Within a simple two-period overlapping
generation model, I show that given an increase of the desired number of children
age at marriage is affected through two different channels. First, as population growth
increases, the age structure of the population produces a thicker market for young
people, inducing early marriages. The second channel comes from differential fecundity:
if the desired number of children is not feasible for older women, women tend to marry
younger and men older, with single men outnumbering single women in equilibrium. Using
an extended version of the model to a finite number of periods and fertility data,
I show that two mechanisms described above may have acted as persistence mechanisms
after the U. S. Baby Boom. Specifically, I find that the demographic transitional
dynamics after the Baby Boom may account for approximately 23 percent of the increase
in men's age of marriage between 1985 and 2009, although the impact on women's age
is small.
