|December 2018||Multigenerational Effects of Early Life Health Shocks|
with Jason M. Fletcher, Angela Forgues: w25377
A large literature has documented links between harmful early life exposures and later life health and socioeconomic deficits. These studies, however, are typically unable to examine the possibility that these shocks are transmitted to the next generation. Our study traces the impacts of in utero exposure to the 1918 influenza pandemic on the outcomes of the children and grandchildren of those affected using representative survey data from the US. We find evidence of multigenerational effects on educational, economic, and health outcomes.
|June 2017||High School Genetic Diversity and Later-life Student Outcomes: Micro-level Evidence from the Wisconsin Longitudinal Study|
with Jason M. Fletcher: w23520
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 hypotheses by aggregating representative data to the high school level from a single state (Wisconsin) in 1957, when the population was composed nearly entirely of individuals of European ancestry. Using this sample of high school aggregations, we too find a strong effect of genetic diversity on socioeconomic outcomes. Additionally, we check an existing mechanism and propose a new potential mechanism of the results for innovation: personality traits associated with creativity and divergent thinking.

|January 2015||Understanding Heterogeneity in the Effects of Birth Weight on Adult Cognition and Wages|
with Jason M. Fletcher: w20895
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 literatures. We use a sample of siblings combined with an “orchids and dandelions hypothesis”, where the IQ of genetic dandelions is not affected by in utero nutrition variation but genetic orchids thrive under advantageous conditions and wilt in poor conditions. Indeed, using variation in three candidate genes related to neuroplasticity (APOE, BDNF, and COMT), we find substantial heterogeneity in the associations between birth weight and adult outcomes, where part of the population (i.e., “dandelion...
