Graduate Student Angela Cools' and Professor Eleonora Patacchini's recent working paper examines the impact of sibling gender composition on women’s adult earnings. .
The Independent recently highlighted their work in a piece detailing gender pay disparities in the UK and an upcoming push for companies to publish gender pay gap figures on their websites.
Using data collected from US-based Add Health, Cools and Patachhini "found that having a brother lowered earnings by approximately 10 percent for a woman in her late 20s or early 30s. If no women had brothers, the overall gender pay gap would likely be around 5 percent smaller, their research claims.
The gap can largely be attributed to the fact that – generally – women with brothers tend to focus more on family and tend to prioritise being in a committed relationship over those who only have a sister or have no siblings at all. Those with brothers, the researchers say, also tend to display a greater intention to have children." Cools and Patacchini also "found no evidence that differences in parental investment, cognitive abilities, parental expectations, or personality traits drive the earnings power."
