The authors investigated the causal relationship between within-group gender preference and gender imbalance in the labour market. First, they looked at gender discrepancies in the selection phase of the hiring process using a meta-analysis. Then, using data from a large correspondence study of fictitious CVs sent in response to job advertisements, they examined recall rates. The meta-analysis of previous correspondence studies shows that women are more likely to be invited for an interview. Consistent with this finding, the authors were able to demonstrate in a correspondence experiment that female applicants receive preferential treatment at the recall stage. In the pooled sample for all occupations, women had a higher probability than men of being invited to an interview.
