ABSTRACT
Considering that progressive gender attitudes prioritise the needs of females, and traditional gender attitudes prioritise the needs of males, it is puzzling that I find female and male gender attitudes hardly differ according to the 2017-2022 World Values Survey. Using a concept from biological anthropology, Gendered Fitness Interest, I hypothesise that some may prioritise gender attitudes that do not favour their own needs, but favour the needs of their descendants. In terms of revealed preferences, I find that females with more female (male) descendants rather than male (female) descendants of reproductive age perform less (more) non-paid work and have greater (lesser) labour supply. Conversely, males with more female (male) descendants rather than male (female) descendants of reproductive age perform more (less) non-paid work and have lesser (greater) labour supply. Additionally, I identify that individuals with progressive gender attitudes have female children preferences and those with traditional gender attitudes have male children preferences. I demonstrate how not taking into account this `stopping-rule' behaviour provides endogenous estimates of the effect of descendant kin on time use.
