Life Earnings and Rural‐Urban Migration
从理论上研究战后低收入经济体中常见的城乡迁移（城市化）现象，将其视为劳动力从传统土地密集型技术向具有无限增长潜力的人力资本密集型技术的转移，强调城市作为新移民积累现代生产所需技能场所的作用。
This paper is a theoretical study of rural‐urban migration—urbanization—as it has occurred in many low‐income economies in the postwar period. This process is viewed as a transfer of labor from a traditional, land‐intensive technology to a human capital–intensive technology with an unending potential for growth. The model emphasizes the role of cities as places in which new immigrants can accumulate the skills required by modern production technologies.
