“…men are more likely than women to make the opening offer and men fight harder when left out from a coalition. As such, we contribute to the vast experimental economics literature on gender differences which has found that men are more inclined to enter competitions (Niederle and Vesterlund, 2007), contribute ideas (Coffman, 2014), lead a team (Born et al, 2020), or give advice on how to play strategically (Cooper and Kagel, 2016). Importantly, by now, it is also a robust finding that women's decision-making is influenced by gender stereotypes, as well as by gender composition, when the domain is stereo-typically perceived as disadvantageous for women (Coffman, 2014;Bordalo et al, 2019;Geraldes, 2020).…”
