This paper by Bryan O’Keefe and Richard Vedder raises a provocative question. Does the increase in college enrollment over the past 30 years partly reflect the changing pressures on employers based on a 1971 Supreme Court decision? And if so, could these pressures also explain the much-touted increase in earnings that comes from a college education?

O’Keefe and Vedder explore the impact of the Griggs v. Duke Power decision on today’s college enrollment. In Griggs, the plaintiffs argued that Duke Power’s reliance on two aptitude tests discriminated against minority groups. Subsequent cases and statutory law have changed the environment for employer testing. This may have changed the pressure to attend college.
