We also find that stronger group identification leads people to put more weight on positive signals, and less weight on negative signals, about their group's relative performance on the test. Our r...

We report data from a laboratory experiment where a powerful buyer can trade with one of two sellers—an environment that can lead to very low prices for the sellers. We find that low procurement prices trigger significantly less punishment by sellers if the buyer uses a competitive auction ...
