The research aims at revealing the perception of young women (and men) about the role of (religious) headscarf for female integration in the public sphere. In particular, it attempts to understand the rationale behind the use of head scarf among young female women in the context of contemporary Muslim society. The hypothesis tested here is that the headscarf is used by young female population to smoothen their transition into the labor market. The particular mechanism we are interested in is to see whether young female women (and men) perceived that wearing this religious garb could help these young females to avoid/compensate the stigma from taking jobs that require them to venture beyond their domestic compound.

Experimental Design

Experimental Design
Respondents will be randomly allocated to receive different profiles and different job advertisements. They will then be asked to choose a job that is suitable for the subject.
Experimental Design Details
This is a survey experiment using a survey mobile app. The respondents will be shown hypothetical profiles and job advertisements in two rounds. In each round, the respondents in different groups will be shown a vignette with a profile of the same female subject (actress) with a photograph where the subject is not veiled in control condition, but is veiled in the treatment condition. The respondents will then be asked to choose a job that they think is suitable for the subject described in the vignette. The choice of jobs are between an online job--which does not formally require the subject to leave their home--and a public facing job. In the second round, the respondents will be shown different female subject than the first round (but similar subject across groups, with different veil treatment across treatment groups) and then will be asked to choose a job (online vs. public facing) that they think is suitable for the subject in the vignette. After the two rounds of job compatibility perception, the respondents will then be asked about their perception on different traits related the subject featured in the vignettes. In particular, these traits are related to subject's moral values and subject's desirability in the marriage market. These treatments will be expanded to include different level of wage for public facing job, while wage for online job is kept constant. Hence, we have different wage differential (gap) between online and public facing job. I plan to have six different wage level of public facing job.
