Individualism is associated with an emphasis on personal liberty and self-determination, values that reduce support for patriarchal values and increase gender equality. Here, we investigate whether individualism affects women’s economics rights, a key institutional determinant of the economic opportunities available to women. We provide evidence of an economically and statistically significant association between individualism and the de facto level of women’s economic rights. This result is robust to controls for a variety of measures, including per capita income, women’s educational attainment, oil production, historical determinants of patriarchal culture, and the quality of legal and political institutions. In addition, we present evidence that this association is causal, drawing on instruments motivated by roles of climate and disease in cultural evolution. Finally, we show that individualism’s influence on women’s economic rights is magnified in democratic and common law countries, suggesting that democracies and common law systems channel cultural preferences into legal outcomes.
