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...

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:...

Lower birth weight babies have worse outcomes, both short-run in terms of one-year mortality rates and longer run in terms of educational attainment and earnings. However, recent research has called into question whether birth weight itself is important or whether it simply reflects other...

We describe changes over time in inequality in postsecondary education using nearly seventy years of data from the U.S. Census and the 1979 and 1997 National Longitudinal Surveys of Youth. We find growing gaps between children from high- and low-income families in college entry, persistence, and...

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...

More than a half century after its peak, the baby boom's causes remain a puzzle. A new argument posits that rapid advancements in household technology from 1940 to 1960 account for this large increase in fertility. We present new empirical evidence that is inconsistent with this claim. Rapid...

More able parents tend to have more able children. While few would question the validity of this statement, there is little large-scale evidence on the intergenerational transmission of IQ scores. Using a larger and more comprehensive dataset than previous work, we are able to estimate the...

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,...

Does it matter when a child starts school? While the popular press seems to suggest it does, there is limited evidence of a long-run effect of school starting age on student outcomes. This paper uses data on the population of Norway to examine the role of school starting age on longer-run...

Among the perceived inputs in the production' of child quality is family size; there is an extensive theoretical literature that postulates a tradeoff between child quantity and quality within a family. However, there is little causal evidence that speaks to this theory. Our analysis is able to...
