Missing Studies on Discrimination

When we published our meta-analysis on ethnic discrimination in hiring, we were puzzled about the tests indicating missing (unpublished) studies. The same can also be found for discrimination in the housing market. A while ago, I looked at the Neumark test as a possible explanation. After more reflection (and a discussion with Anthony Heath), I now suggest there might indeed missing studies in the sense of unpublished. Some of the correspondence and audit studies are sponsored by agencies with a clear agenda of showing the existence of discrimination. While for academics a study not finding much discrimination may still be worth purusing as a publication, these agencies who fight racism and discrimination may not. We might be looking at small-scale studies, but still. Let’s be clear though, the ‘true’ level of discrimination we can enumerate in a meta-analysis is not what matters: it’s the fact of consistent and systematic discrimination — and a few ‘missing’ studies cannot change this.
