The Effect of Workplace Gender Composition on Investment Interest in Hypothetical Companies.

The current study extends previous work on gendered workplace attitudes by manipulating the workplace gender composition (CEO gender, employee gender) of traditional male and female employment sectors. Participants reported general financial investment interest in purported male-role congruent (science laboratory) and female-role congruent (daycare) start-up companies, where CEO gender and employee gender were orthogonally manipulated. Participants had more favorable investment attitudes toward daycares when the CEO was a woman, and especially favorable investment attitudes when both the CEO and employees were women.

The current study sought to investigate how disease responses in the US population have been modulated by the COVID-19 pandemic, given its origins in China, an outgroup population.
