Professor Ross was invited to write a commentary on measuring trends in discrimination. Specifically, Professor Ross carefully lays out the potential, but also the challenges, of exploiting multiple field studies of discrimination combined with meta-analysis techniques in order to measure changes over time in the level of discrimination. Professor Ross notes recent research in the same journal that shows very stable levels of employment discrimination against African-Americans over several decades in the U.S. On the other hand, his own research has documented substantial declines in the level of housing discrimination, especially among real estate agents for owner-occupied housing. Below is a link to the commentary.
