好邻居：童年邻居影响职业选择

Occupation choice is a key determinant of economic mobility. This paper studies how childhood neighbors influence occupational choices and later-life earnings. Using linked historical U.S. census records for over six million boys and four million girls, we reconstruct neighborhood microgeography to identify childhood neighbors and their occupations. We find that living next door to someone in a given occupation increases the probability of working in that same occupation 30 years later by about 10 percent relative to other children on the same street. The transmission effect is higher with more intense exposure, in more connected neighborhoods, and when neighboring families are more similar. Exposure to high-income or highly educated neighbors has lasting economic effects, leading to significant gains in adult income and education even compared to other children from the same street. These findings suggest that neighborhood networks play an important role in shaping intergenerational economic mobility.
