This paper examines the impact of youth friendship links on student's own academic performance (grade point average) using the Add Health. We estimate a reduced form, high dimensional fixed effects model of within cohort or grade friendship links, and use this model to predict each student's...

The multi-decade growth and spatial dispersion of immigrant families in the United States has shifted the composition of US schools, reshaping the group of peers with whom students age through adolescence. US-born students are more likely to have foreign-born peers and foreign-born students are...

Nascent research suggests intergenerational health mobility may be relatively high and non-genetic factors may make room for policy intervention. This project broadens this direction by considering heterogeneous intergenerational health mobility in spatial and contextual patterns. With 14,797...

In this paper, we estimate the impacts of abortion clinic closures on access to clinics in terms of distance and congestion, abortion rates, and birth rates. Legislation regulating abortion providers enacted in Wisconsin in 2011-2013 ultimately led to the closure of two of five abortion clinics...

Despite increasing calls for value-based payments, existing methodologies for determining physicians' "value added" to patient health outcomes have important limitations. We incorporate methods from the value added literature in education research into a health care setting to present the first...

Little is known about the relationship between family income and children's non-cognitive (or socio-emotional) skill formation. This is an important gap, as these skills have been hypothesized to be a critical link between early outcomes and adult socioeconomic status. This paper presents new...

A large economics literature has shown long term impacts of birth weight on adult outcomes, including IQ and earnings that are often robust to sibling or twin fixed effects. We examine potential mechanisms underlying these effects by incorporating findings from the genetics and neuroscience...

Although the measurement of intergenerational income mobility has seen a rapid increase in attention and policy discussions, similar examinations of educational mobility in the U.S. are lacking. This paper begins to fill this gap by documenting differences in educational mobility across time...

A novel hypothesis posits that levels of genetic diversity in a population may partially explain variation in the development and success of countries. Our paper extends evidence on this novel question by subjecting the hypothesis to an alternative context that eliminates many alternative...

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...
