Labour-market discrimination is both unjust and inefficient. It hurts people, it heightens inequality and it hampers economic growth. If we want to combat discrimination, we need to understand how it works. This is particularly important for the future of our increasingly diverse European societies. The study of discrimination poses, however, major methodological challenges for social and behavioural scientists.

Directed by Javier Polavieja, the D-Lab at UC3M is aimed at advancing the scientific study of discrimination and social inequality by promoting rigorous empirical research and methodological innovation. The lab provides a unique infrastructure to carry out cutting-edge field-experimental research on labour-market discrimination in Spain.


The lab currently runs two large competitive projects: the GEMM project, financed by the EU, and the newAir project, financed by the Spanish Ministry of Economy and Competitiveness. As part of the GEMM project, the D-Lab participates in a unique comparative field-experiment on ethnic discrimination in employment, which we are carrying out simultaneously in five European countries: Germany, the Netherlands, Norway, United Kingdom and Spain.

The D-Lab includes a core team plus associate fellows. The core team is currently formed by two post-doctoral research fellows, one ICT fellow, one doctoral fellow, four research assistants, plus the PI. Associate fellows of the lab are academics from institutions both within UC3M and further afield who are collaborating with lab researchers on specific research projects. We have currently seven associate fellows. 

The lab offers on-the-project training for both undergraduate and postgraduate students and it is a springboard for young scholars’ early career development. 

The D-Lab's advisory board includes world-leading experts in the fields of migration, social inequality and experimental research.

Launched in 2018, the D-Lab is expected to soon become a centre of reference in the study of discrimination both in Europe and beyond.
