Monitoring hiring discrimination through online recruitment platforms

15.11.2021

Women (compared to men) and individuals from minority ethnic groups (compared to the majority group) face unfavourable labour market outcomes in many economies but the extent to which discrimination is responsible for these effects, and the channels through which they occur, remain unclear. Although correspondence tests — in which researchers send fictitious CVs that are identical except for the randomized minority trait to be tested (for example, names that are deemed to sound `Black versus those deemed to sound `white`)—are an increasingly popular method to quantify discrimination in hiring practices, they can usually consider only a few applicant characteristics in select occupations at a particular point in time.

To overcome these limitations, Dominik and his colleagues Daniel Kopp and Michael Siegenthaler developed an approach to investigate hiring discrimination that combines tracking of the search behaviour of recruiters on employment websites and supervised machine learning to control for all relevant jobseeker characteristics that are visible to recruiters. The researchers applied this methodology to the online recruitment platform of the Swiss public employment service and found that rates of contact by recruiters are 4–19% lower for individuals from immigrant and minority ethnic groups, depending on their country of origin, than for citizens from the majority group. Women experience a penalty of 7% in professions that are dominated by men, and the opposite pattern emerges for men in professions that are dominated by women. Furthermore, minority ethnic groups faced larger penalty just before lunch or towards the end of the workday, when recruiters spent less time on each CV. This methodology provides a widely applicable, non-intrusive and cost-efficient tool that researchers and policy-makers can use to continuously monitor hiring discrimination, to identify some of the drivers of discrimination and to inform approaches to counter it.

Dr. Niklas Harder is co-head of the integration department at the DeZIM Institute and a research affiliate with the Immigration Policy Lab at Stanford University. His main research interests are in the areas of integration and political participation. He also works on the evaluation of integration policy measures in Europe and North America. To do this, he applies current methods of causal inference to survey data as well as process-generated and administrative data.
