We examine whether there is return to the ability of analyzing data in the labor market in China for undergraduate students majoring in economics. We are conducting a large-scale audit study and submitted resumes of fictitious candidates to job advertisements positions posted on a popular job search platform. To manipulate perceived data analysis ability, resumes are randomly assigned different levels of data analysis skills.

Experimental Design

Experimental Design
We submitted resumes from fictitious candidates to job openings in major Chinese cities on a large job search website. While we keep the content of the resume largely the same, we randomly vary the ability of data analysis skills in the resume. The control resume includes seniors majoring in economics who do not indicate that they have any data analysis skills. The treatment one resume includes seniors majoring in economics who indicate that they knows stata programming skills. The treatment two resume includes seniors majoring in economics who indicate that they knows python programming skills. In both treatment group and control group, they conducted internships but differed in their capacity of analyzing data. Otherwise the resume are identical in three groups.
