中文摘要
在许多发展中经济体中，同等教育水平的城市劳动者收入远高于农村劳动者。为什么没有更多农村劳动者迁移到城市？我利用肯尼亚的两项实地实验表明，低迁移率部分归因于对城市收入的低估，而这种低估因迁移者的收入隐藏而得以维持。原籍地的父母对其迁移子女收入的低估幅度接近一半，且当迁移者的汇款义务较高时，低估程度更大。提供关于城市收入的信息使两年内迁往首都的人数增加了约40%。（JEL C93, J31, J61, J82, O15, O18, R23）
Abstract
In many developing economies, urban workers earn substantially more than rural workers with the same level of education. Why don't more rural workers migrate to cities? I use two field experiments in Kenya to show that low migration is partly due to underestimation of urban incomes, which is sustained by income hiding by migrants. Parents at the origin underestimate their migrant children's incomes by nearly half, and underestimation is greater when a migrant's remittance obligations are high. Providing information about urban earnings increases migration to the capital city by about 40 percent over two years. (JEL C93, J31, J61, J82, O15, O18, R23)
