"Negotiation really has to do with ego and timing," Corcoran tells CNBC Make It.
Roughly three decades ago, Corcoran was approached with an offer to sell her real estate business The Corcoran Group, and she was interested in cashing out, she says.
So, when real estate company NRT offered her $22 million for The Corcoran Group roughly 10 years later, in 2001, she quickly submitted her counteroffer — asking for $66 million instead.
"As a real estate broker running 1,000 sales agents, I had to teach them negotiating skills," Corcoran says.
But the trend dissipates as women gain negotiating experience, noted a 2015 moderator analysis published in The Psychological Bulletin.
