Racial diversity in higher education is associated with higher student salaries

Area of Science:

• Higher education policy
• Economics
• Sociology

Background:

• The US Supreme Court's 2023 decision on affirmative action highlights the ongoing relevance of racial diversity in higher education admissions.
• Existing theories present conflicting predictions regarding the economic impact of racial diversity in educational cohorts.
• There is a lack of empirical data on the relationship between racial diversity and graduate salaries.

Purpose of the Study:

• To investigate the association between racial diversity in higher education cohorts and subsequent graduate salaries.
• To provide empirical evidence to inform discussions on diversity in higher education and its economic implications.

Main Methods:

• Compilation of two large datasets: 2,964 Master of Business Administration (MBA) cohorts from 141 business schools (29 years) and 3,386 Juris Doctor (JD) cohorts from 200 law schools (21 years).
• Statistical analysis controlling for student quality, university, and year to assess the impact of racial diversity on cohort median salaries at graduation.

Main Results:

• A positive association was found between higher cohort racial diversity and higher median salaries at graduation for both MBA and JD cohorts.
• This association remained consistent across various model specifications and after controlling for key confounding variables.

Conclusions:

• Policies aimed at increasing or utilizing racial diversity in higher education are associated with enhanced human capital.
• The findings suggest that diversity initiatives can yield significant economic benefits for graduates and society.
