The causal effects of fertility are a central focus in the social sciences, but the analysis is challenged by the endogeneity of fertility choices. Earlier work has proposed several "natural experiments" from twin births or gender composition of earlier births to assess whether having more...

We describe how the COVID-19 pandemic affected reproductive choices in New York City, the most acutely impacted area of the United States. We contrast changes in New York City with reproductive outcomes in the rest of the US. We find that births to New York City residents fell 8.4% more between...

We use a unique data set of linked birth records from Florida to analyze the intergenerational transmission of health at birth by parental gender. We show that both paternal and maternal birth weights significantly predict the child's birth weight, even after accounting for all genetic and...

This paper introduces four new intergenerational and multigenerational datasets which follow both sons and daughters and which can be used to study the persistence of longevity, socioeconomic status, family structure, and geographic mobility across generations. The data follow the children of...

Using newly digitized U.S. city-level data on hospitals, we explore how pandemics alter preferences for healthcare. We find that cities with higher levels of mortality during the Great Influenza of 1918-1919 subsequently expanded hospital capacity by more than cities experiencing less influenza...

Access to safe and stable housing is important for child and adult wellbeing. Yet many low-income households face severe challenges in maintaining stable housing. In this paper we examine the impact of the 2021 temporary expansion to the Child Tax Credit (CTC) on the living arrangements and...

A growing literature explores the impact of home-based versus office-based work. Differences in productivity may arise due to a treatment effect of the office or from workers with different abilities sorting into office or home work. We conduct an RCT in the data entry sector in India that...

Does the intellectual endowment of children affect parents' fertility choices? The quantity-quality model of fertility predicts that a positive (negative) shock to child endowment increases (decreases) parental demand for children. We test these predictions using Israeli data on intellectually...

Programs that engage young children in movement and song to help them learn are popular but experimental evidence on their impact is sparse. We use an RCT to evaluate the effectiveness of Big Word Club (BWC), a classroom program that uses music and dance videos for 3-5 minutes per day to...

Due to population aging, GDP growth per capita and GDP growth per working-age adult have become quite different among many advanced economies over the last several decades. Countries whose GDP growth per capita performance has been lackluster, like Japan, have done surprisingly well in terms of...
