Research highlights
-
In our meta-analysis (published in European Economic Review), we synthesise a quasi-exhaustive register of correspondence audit experiments in hiring published between 2005 to 2020. We show that hiring discrimination is similarly severe for candidates with disabilities, older age, and less physical attractiveness as for those with distinct racial or ethnic characteristics, with older candidates facing more discrimination in Europe and no clear evidence of decreasing discrimination over time.
-
In an experimental study (published in Computers in Human Behavior: Artificial Humans), I explore whether OpenAI’s GPT-3.5 displays ethnic or gender bias in job applicant screening using an audit approach. I show that GPT’s evaluations are influenced by ethnic cues, with some evidence for a gender–ethnicity interaction, highlighting the need for caution in using such models for selection decisions.
-
In our contextual study of hiring discrimination (published in Labour Economics), we empirically test theoretically-linked moderators of discrimination. We observe a distinct role of the organisation in shaping hiring discrimination, revealing that ethnic minorities face less discrimination when applying to non-profits or large organisations, alongside some evidence that hiring discrimination rises in jobs with more colleague interaction or lower tightness.
