Are you planning to run a field experiment, perhaps even on discrimination in hiring decisions? As a complement to our meta-analysis of existing field experiments on ethnic discrimination in hiring, you could do worse than reading two recent working papers by my co-author Eva Zschirnt: In one, she outlines the history of field experiments in much more detail than a journal article can do, in the other she collects ethical considerations in a single place.
