Abstract
This study examines whether receiving an associate's degree from a community college harms a graduate's labor market prospect, conditional on the graduate also having received a bachelor's degree. Furthermore, if we detect any such effect on labor market outcomes, this study examines whether the effect is due to statistical discrimination or due to pure stigma against community college graduates.

Primary Outcomes
Primary Outcomes (end points)
Call back rate.
Primary Outcomes (explanation)
Call back is defined as a personal email or voicemail from an employer indicating an interest to invite the job applicant for an interview or an interest in knowing more information about the applicant.
Secondary Outcomes
Secondary Outcomes (end points)
Employer's quality.
Secondary Outcomes (explanation)
Employer's quality is defined by a unified scale that would be further disclosed once the trial ends.
Experimental Design
Experimental Design
The study team send out artificial resumes through an online job search platform.
Experimental Design Details
The study send out artificial resumes through one of the largest online job search platform in the US. We use a total of 600+ artificial application resumes, and apply to jobs across the entire country in two occupations: accounting and sales. We subdivide the resumes into 8 groups defined by the occupation the resumes are designed for and the geographic location of the job applicants (West Coast, South, Midwest, and Northeast). Within each occupation-geography group, there are eight different types of resumes: selective 4-year 3.2 gpa, non-selective 4-year 3.2 gpa, community college + selective 4-year 3.2 gpa, community college + selective 4-year 3.4 gpa, community college + selective 4-year 3.6 gpa, community college + non-selective 4-year 3.2 gpa, community college + non-selective 4-year 3.4 gpa, community college + non-selective 4-year 3.6 gpa. The rest of the resumes, including relevant courses, employment experiences, and skills were randomized across the eight resumes. The names of the applicants were deliberately selected to indicate a Caucasian individual, and gender was evenly split.
Randomization Method
Randomization was done in office with random number generator.
Randomization Unit
Randomization unit is each of the 600+ individual resumes.
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
600+ resumes.
Sample size: planned number of observations
3000~5000 job applications.
Sample size (or number of clusters) by treatment arms
Each of the eight treatment arms (sel 4yr 3.2, no-sel 4yr 3.2, cc-sel 4yr 3.2, etc.) will have equal numbers of job applications.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
