This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual’s labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of...

Dramatic fertility swings over the last 100 years have been the subject of large literatures in demography and economics. Recent research has claimed that the post-1960 fertility decline is exceptional enough to constitute a "Second Demographic Transition." The empirical case for a Second...

Fueled by new evidence, there has been renewed interest about the effects of birth order on human capital accumulation. The underlying causal mechanisms for such effects remain unsettled. We consider a model in which parents impose more stringent disciplinary environments in response to their...

This paper assembles new evidence on some of the longer-term consequences of U.S. family planning policies, defined in this paper as those increasing legal or financial access to modern contraceptives. The analysis leverages two large policy changes that occurred during the 1960s and 1970s:...

We estimate the effect of fertility on female labor force participation in a cross-country panel data set using abortion legislation as an instrument for fertility. We find a large negative effect of the fertility rate on female labor force participation. The direct effect is concentrated among...

The 1960s ushered in a new era in U.S. demographic history characterized by significantly lower fertility rates and smaller family sizes. What catalyzed these changes remains a matter of considerable debate. This paper exploits idiosyncratic variation in the language of "Comstock" statutes,...

All nations that can be characterized as developed have undergone the demographic transition from high to low levels of fertility and mortality. Most presently developed nations began their fertility transitions in the late nineteenth or early twentieth centuries. The United States was an...

Medical practitioners typically utilize the following protocol when advising pregnant women about testing for the possibility of genetic disorders: Pregnant women over the age of 35 should be tested for Down syndrome and other genetic disorders; for younger women, such tests are discouraged...

Almost 50 years after domestic U.S. family planning programs began, their effects on childbearing remain controversial. Using the county-level roll-out of these programs from 1964 to 1973, this paper reevaluates their shorter- and longer-term effects on U.S. fertility rates. I find that the...

This paper examines how marital and fertility patterns have changed along racial and educational lines for men and women. Historically, women with more education have been the least likely to marry and have children, but this marriage gap has eroded as the returns to marriage have changed....
