In this paper, we quantify hateful content in online civic discussions of politics and estimate the causal link between hateful content and writer anonymity. To measure hate, we first develop a supervised machine-learning model that predicts hate against foreign residents and hate against women...

In a laboratory experiment, we show that subjects incorporate irrelevant group information into their evaluations of individuals. Individuals from on average worse performing groups receive lower evaluations, even if they are known to perform equally well as individuals from better performing...

This study shows that transient anonymity affects buyer discrimination based on seller’s gender and foreignness in online auctions. Sellers’ names are categorized by gender and foreignness. Half of the sellers’ disclose their names in the usernames and the other half employ anonymous...

This paper analyzes a two-person, two-stage model of sequential exploration, where both information and payoff externalities exist, and tests the derived hypotheses in the laboratory. We theoretically show that even when agents are self-interested and perfectly rational, the information...

In this laboratory experiment, we show that people incorporate irrelevant group information when evaluating others. Individuals from groups that perform badly on average receive low evaluations, even when it is known that the individuals themselves perform well. This group-bias occurs both in a...

We study the stability of voluntary cooperation in response to varying rates at which a group grows. Using a laboratory public-good game with voluntary contributions and economies of scale, we construct a situation in which expanding a group’s size yields potential efficiency gains, but only...

A recent literature emphasizes the importance of the gender gap in willingness to compete as a partial explanation for gender differences in labor market outcomes. However, whereas experiments investigating willingness to compete typically do so in anonymous environments, real world competitions...
