Wage earners, homemakers & gender identity

Using an experiment to understand division of labour choices in couples: Why do only few couples choose the female spouse as main provider of labour income? To understand gender imbalances among family breadwinners, I present a collective household production model with identity concerns that illuminates different channels through which gender norms can affect household specialisation decisions. To test the predictions of the model regarding identity, I develop a novel experimental paradigm to study the specialisation choices of real heterosexual couples in the lab. Women are less likely to become breadwinners than men are, but this is mainly due to gender differences in productivity. While I find little evidence that concerns for gender identity affect specialisation choices, the results suggest they amplify gender differences in labour supply at the intensive margin. The design further allows me to shed light on two additional factors that contribute to the gender imbalance among breadwinners: men’s overconfidence and women’s reluctance to assume sole responsibility for household income.
