Experimental Design

Experimental Design
To access the attitude towards certain groups on the labor market, we send fictitious resumes in respond to real job openings, varying the characteristics of CVs.
Experimental Design Details
We provide the correspondence experiment in Russia to understand the job prospects of native and ethnic self-employed applicants.
Within the framework of the experiment we send 12.000 CV's in response to 3.000 vacancies. We cross randomize if (1) a person was self-employed or worked for a company and (2)a person has a Slavic or ethnic minorities sounding name.
We apply for the similar occupations with different skill-levels: High (Skill level 4) or low(skill level 2) skill level job according to International Standard Classi cation of Occupations (2008). Namely, we send resume on the next vacancies in Skill level 4: Finance Managers (1211), Advertising and Public Relations Managers (1222), Information and Communications Technology Services Managers (1330). In skill level 2: Accounting Associate Professionals (3313); Conference and Event Planners (3332); Information and Communications Technology Operations Technicians (3511).
