Academic origins in economics departments, defined as the universities at which tenure-track faculty completed their doctoral studies, may have implications for how the department’s undergraduate and PhD students are trained and placed, as well as the type of research produced. In this project, we use roster data on the academic origins of the tenure-track faculty at 96 U.S. economics departments with graduate degrees. We use these data to document patterns in academic origins across several dimensions, including department ranking, gender, rank (Assistant, Associate, Full Professor), and geography. We find that 1) over half of the faculty of each of eight top departments received their PhD from one of these same universities; 2) at least half of faculty from all top-25 departments come from top-15 universities; 3) over half of Harvard and MIT faculty received their PhD at either Harvard or MIT; and 4) over half of all faculty in the study come from top-15 universities, with Harvard, MIT, and the rest of the top six disproportionately represented. The first and third findings are more pronounced for female faculty.
