Using restricted-access "Survey of Earned Doctorates" data, we investigate which attributes of a doctoral institution predict the share of its undergraduate BAs that will earn a PhD. We use truncation-correction to account for PhD receipt post-sample. Across the fields of humanities, physical, natural, and social sciences, PhD production is positively related to the number of an institution's highly-ranked PhD programs, suggesting such departments may play a role in both producing PhDs and encouraging undergraduates to earn PhDs themselves. It is negatively related to total students and the share of BAs received in the field, and positively related to test scores.
