Abstract
In this correspondence study, we test for labor market discrimination in Malaysia by ethnicity and gender. In addition, we evaluate whether soft skill signals (leadership, teamwork, or none) are valued in the labor market, and their interaction with discriminatory behavior.

Primary Outcomes

Primary Outcomes (end points)
request for interview
Primary Outcomes (explanation)
request for interview is a dummy variable that takes the value of 1 if the company (employer) offered an interview to the candidate (contact).

Secondary Outcomes

Secondary Outcomes (end points)
profile viewed, and number of profile views, days to interview, days to determination of unsuitable
Secondary Outcomes (explanation)
Profile views is a dummy variable that takes the value of 1 if the employer viewed the profile of the candidate, or number of times employer viewed the profile of the candidate. For contacted profiles, we can compare the average number of days between application submission and interview offer by ethnicity and gender. We can perform a similar analysis for profiles that were declared not suitable.

Experimental Design

Experimental Design
To assess labor market discrimination in Malaysia, we will utilize a correspondence study. Using this method, fictitious job applications are sent to employers that have advertised a job opening. Each job ad is randomly assigned a specific applicant profile. In this way, the applicant profile is the randomly assigned "treatment." The only meaningful differences between applicant profiles is the name (and contact information) of the applicant, which signals ethnicity and/or gender, and a signal of soft skills. By randomly assigning an applicant profile, these characteristics are randomly assigned. Using this method, the study will causally identify the degree of discrimination in hiring in two ways: by calculating the difference in the interview request rate between the various groups and by calculating the difference in the average number of profile views after applying to a job. We perform this analysis for five different degree specializations: Accounting, Business Administration, Computer Science, Electrical Engineering and Mechanical Engineering.
Experimental Design Details
We use an online platform which creates some unique advantages relative to other studies. Specifically, we observe several characteristics of the firm and job that are not typically observable to researchers. In addition, we observe how many times employers view the application profiles and characteristics of the applicant pool. That is, how many applicants in the pool are more or less educated, and how many applicants have higher or lower expected salary.
Randomization Method
application profiles are randomly assigned to job ads in using a computer algorithm
Randomization Unit
individual job advertisement
