While sexism in the workplace is an issue that impacts women on a daily basis, it can be hard to gather data that supports its existence. This research paper might have proven it.

Yellin’ at Yellen: Gender Bias in the Federal Reserve Congressional Hearings investigates the sexism that congressmen exhibit when interacting with their coworkers who are women, particularly through Janet Yellen, who was the first female chair of the Federal Reserve from 2014 to 2018.

To measure the discrimination female politicians face, the paper compared how congressmen behaved towards Yellen as opposed to their treatment of her male predecessors.

"We find that legislators who interacted with both Yellen and at least one other male Fed chair over this period interrupt Yellen more, and interact with her using more aggressive tones," the paper reads.

In 2014, the same congressmen were 14 percent more likely to interrupt Yellen than they were to interrupt Ben Bernanke in 2013. They were 18 percent less likely to interrupt her successor, Jay Powell, in 2018.

Another noteworthy statistics the study reports is that congressmen with daughters were less likely to interrupt Yellen, aligning with the theory that that men with daughters are less likely to engage in sexist behavior.

While studying Yellen alone provided a limited pool of data, researchers said that the harm done is still provably present.

"Even if we limit our contribution to documenting sexism experienced by Janet Yellen, we argue that this is a non-trivial finding as sexism undermines the purpose of these hearings," the report reads. "These hearings are a crucial mechanism of democratic accountability on the performance of the chair of the Federal Reserve."

It continues: "Our contribution is an urgent call to recognize and remove the subtle layers of a political glass ceiling on women and create a more equitable policy environment benefiting the greater public good."
