Replication data for: Trumping Norms: Lab Evidence on Aggressive Communication before and after the 2016 US Presidential Election

This paper provides evidence from a negotiation experiment that the 2016 US presidential election of Donald Trump had a profound impact on individual behavior in the lab. Using a Battle of the Sexes game with unstructured communication, we find that post-election individuals are less cooperative in general, more likely to use adversarial negotiation strategies, and less likely to reach an agreement. Furthermore, this is particularly driven by men acting more aggressively toward women. Our results are robust to controlling for sample selection. These results suggest that Trump's election may have disrupted community norms around civility and chivalry.
