The study looked at the difference in wages between men and women in Switzerland. Instead of using traditional methods, the researchers used a new technique called matching to break down the wage gap. They found that differences in the support system for men and women play a big role in explaining why women earn less. This suggests that women face barriers that prevent them from accessing certain opportunities that men have, leading to discrimination in wages. Taking these differences into account could help create policies to promote more equality between men and women.
