Abstract
We study employers’ perceptions of the value of postsecondary degrees using a field experiment. We randomly assign the sector and selectivity of institutions to fictitious resumes and apply to real vacancy postings for business and health jobs on a large online job board. We find that a business bachelor’s degree from a for-profit “online” institution is 22 percent less likely to receive a callback than one from a non-selective public institution. In applications to health jobs, we find that for-profit credentials receive fewer callbacks unless the job requires an external quality indicator such as an occupational license.

Interventions

Intervention(s)
Despite growing demand, the supply of highly skilled college graduates in the U.S. has not kept pace. In contrast to sluggish growth in the public sector, enrollment in for-profit institutions has grown rapidly over the last fifteen years. Yet little is known about the labor market return to a for-profit education. Do employers value credentials from some institutions more than others? We address these questions using a large-scale resume audit field experiment. We construct fictitious resumes, randomly vary the institution from which the job applicant received a degree or certificate, and apply to job vacancies that are posted on a large, national job search website. While our primary research question concerns employers’ valuations of a for-profit versus public credential, we also test the impact of having any credential for job vacancies that do not require it. Additionally, our planned sample size allows us to examine heterogeneity by occupation, degree, and labor market. In this pre-analysis plan, we describe the structure of the experiment, and we present early results from a pilot version of our study. The full version of the study went into the field on Monday, March 31st and will conclude by the end of November 2014.

Yes

Experiment Characteristics

Sample size: planned number of clusters
2,621 job vacancies.
Sample size: planned number of observations
10,484 resumes.
Sample size (or number of clusters) by treatment arms
2,621 in each of 4 treatment arms.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Our power calculations suggest that we will be able to detect a 1 percentage point difference at a significance level of 5 percent and at 80 percent power for the overall treatment, and 1.5 percentage points for key subgroups.
