This paper provides an empirical examination of the factors that influ
ence graduate admissions decisions. It exploits a unique, large data s
et on applications and admissions to 48 leading graduate schools in fi
ve disciplines, including economics, The analysis shows that these gra
duate schools in the aggregate gave substantial preference in four out
of five fields to U.S. citizens over foreign applicants, modest prefe
rence in three fields to women over men, and substantial preference in
all fields to underrepresented minorities over other U.S. citizens, T
he findings suggest that higher standards are applied to overrepresent
ed groups to achieve more diverse enrollments.
