Wharton study: Men are more aggressive toward women since Trump election

Since President Donald Trump was elected, men have become more aggressive when negotiating with women, a University of Pennsylvania study concluded.

Men have become more aggressive in negotiating with women since the 2016 election, according to study from the Wharton School of the University of Pennsylvania.

Corinne Low, Wharton Business Economics and Public Policy professor, and doctoral student Jennie Huang didn't intend to test the effect Donald Trump's election had on the difference in men's and women's negotiating patterns when they conducted the test last fall. But that is what the data showed, the Washington Post reported.

"Not only was the communication more aggressive, it was also less effective," Low told the Post.

In a Battle of the Sexes game, 232 mostly University of Pennsylvania students were paired up, given $20 and asked to divide the money in a $15 to $5 split. If they couldn't work it out, neither would get a share, The Daily Pennsylvanian reported.

In sessions before the election, men were generally more chivalrous and less likely to use tougher strategies against their female partners. After the election, results suggested the "Trump election may have fractured community norms of civility and chiralry," the authors wrote.

"Our results are consistent with literature showing that broader political or world events can impact behavior such as generosity, fairness and reciprocity, cooperation, group bias and health insurance uptake," the authors wrote in the study paper.

The study is to be published in the May edition of the American Economic Review. 

President Trump is a Wharton graduate as is his daughter Ivanka.
