The Long-Run Effects of Peer Gender on Occupational Sorting and the Wage Gap
研究小学阶段同伴性别比例对女性未来职业选择和工资的影响，发现女生比例增加10%可使性别工资差距缩小2.7%，机制是女性更少选择性别刻板印象的职业路径。
We study the impact of the early gender environment on inequality in the labor market. To this end, we link primary school data to occupations and earnings. We find that women exposed to more girls at critical ages earn more later on: A 10 percent increase in the share of girls leads to a gender wage gap reduction of 2.7 percent. We explore mechanisms and find a strong selection of women into less gender-stereotypical educational tracks and occupations, leading to higher earnings. The gender environment at an early age, therefore, leads to persistent changes in career trajectories and earnings.
