Economists and social scientists have debated the relative importance of nature (one’s genes) and nurture (one’s environment) for decades, if not centuries. This debate can now be informed by the ready availability of genetic data in a growing number of social science datasets. This paper explores the potential uses of genetic data in economics, with … Read more

Stop Meta-Analyzing, Start Instrumenting: Maximizing the Predictive Power of Polygenic Scores
Polygenic scores have become the workhorse for empirical analyses in social-science genetics. Because a polygenic score is constructed using the results of finite-sample Genome-Wide Association Studies (GWASs), it is a noisy approximation of the true latent genetic predisposition to a certain trait. The conventional way of boosting the predictive power of polygenic scores is to … Read more
Dynamic complementarity in skill production: Evidence from genetic endowments and birth order
This study looks at how nature and nurture interact in influencing individuals academic attainment, and finds support for the theory that early life parental inputs increase later gains – especially in those children who have genetic advantages. The researchers used data on a sample of 15,000 siblings, whose genetic and demographic information is stored in … Read more
