Understanding determinants of gender differences in economic and social domains has been of interest, both in academic and public debates. Previous research has shown that gender differences in fundamental economic preferences are important in explaining gender differences in economic outcomes, such as for occupational choice, financial investment, or educational decisions, among many others. However, gaps remain in understanding the sources of gender differences in preferences and their variation.

RATIONALE

We contrasted and tested two hypotheses that make opposite predictions concerning the cross-country association of gender differences in preferences with economic development and gender equality. On one hand, the attenuation of gender-specific social roles that arises in more developed and gender-egalitarian countries may alleviate differences in preferences between women and men. As a consequence, one would expect gender differences in preferences to be negatively associated with higher levels of economic development and gender equality (social role hypothesis). On the other hand, greater availability of material and social resources removes the gender-neutral goal of subsistence, which creates the scope for gender-specific ambitions and desires. In addition, more gender-equal access to those resources may allow women and men to express preferences independently from each other. As a consequence, one would expect gender differences in preferences to be positively associated with higher levels of economic development and gender equality (resource hypothesis).

We tested these competing predictions using data on experimentally validated measures of willingness to take risks, patience, altruism, positive and negative reciprocity, and trust for 80,000 individuals in 76 representative country samples. So that the data would be geographically representative, the dataset was chosen so as to include all continents and a broad range of cultures and economic development levels. In total, the data represent about 90% of both the world population and global income.
