The girls, an expert in behavioral economics, learned how the family budget works and discovered something interesting. When a husband earns more than his wife, then of course, the wife takes care of daily life and raising children in the family. When partners earn the same, then in the vast majority of couples the woman is still more involved in everyday life. But when a wife starts earning obscenely more than her husband, you know what happens? It's true, the husband stops worrying about the day-to-day life and the children. No matter how the income is divided in a married couple, everyday life remains mostly with the women. Now guess if it affects demographics, and how exactly. Today, in the Saturday section, behavioral economist Elena Fikolina will talk in more detail about this and other counterintuitive phenomena of the distribution of income and expenses within the family.
