This study seeks to better understand the historical
origins of cross-cultural differences in beliefs about the appropriate
role of women in society. We test the hypothesis that traditional
agricultural practices influenced the historical gender division of labor
and the evolution and persistence of gender norms. We find that,
consistent with existing hypotheses, the descendants of societies that
traditionally practiced plough agriculture, today have less equal gender
norms, measured using reported gender-role attitudes and female
participation in the workplace, politics and entrepreneurial activities.
To test for the importance of culture, we examine second-generation
immigrants living within Europe and the United States. We find that
even among individuals born and raised in the same country, those
with a heritage of traditional plough use exhibit less equal beliefs
about gender roles today.
