Accents, Race and Discrimination: Evidence from a Trust Game

We investigate discrimination according to accent and race on trust behaviour. Proposers were randomly paired with responders of the same/different race, and asked to play the trust game after looking at a photograph and hearing a 10 second audio clip of the responders reading a standardised script in English. This allows us to check for within and across-group favouritism in both race and accentedness. We find that accentedness is a statistically significant predictor of trust and is strongly non-linear in the race of the paired subjects for males but not for females. In the case of males, offers decrease by 11.3% if the responder has a mother-tongue English accent and does not share the same race as the proposer, but increases by about 6.6% if there is racial similarity. This effect is especially pronounced for Black males who are paired with other Black males: offers are 19.5% higher if responders have a mother-tongue English accent. By contrast, females in general seem less sensitive to the signal package. These large gender differences are not because men behave any more strategically than women.
