This paper investigates the relationship between changing community context and out-migration in one of today's poor countries, seeking to document the various mechanisms by which infrastructure affects the migratory behavior. We focus on the expansion of social and physical facilities and services near to rural people's homes, including transportation, new markets, employment, schools, health clinics, and mass media outlets such as movie halls. We draw upon detailed data from Nepal to estimate the hypothesized effects. The direct effects of expanding economic and human capital infrastructure are clearly negative, reducing out-migration. However, increased economic infrastructure is associated with a greater accumulation of human and social capital among respondents and their parents. Through these intervening mechanisms, economic and social infrastructure increased the odds of migrating out. These results reveal the often countervailing nature of short- and long-term effects of economic and social change and the complex pathways influencing migration outcomes.
本文研究了当今一个贫穷国家社区环境变化与外出移民之间的关系,旨在记录基础设施影响移民行为的各种机制。我们关注农村居民家庭附近社会和物质设施及服务的扩张,包括交通、新市场、就业、学校、健康诊所,以及诸如电影院等大众媒体场所。我们利用来自尼泊尔的详细数据来估计假设的影响。经济和人力资本基础设施扩张的直接影响显然是负面的,即减少了外出移民。然而,经济基础设施的增加与受访者及其父母的人力和社会资本的更多积累相关。通过这些中间机制,经济和社会基础设施增加了外出移民的可能性。这些结果揭示了经济和社会变化的短期和长期影响通常相互抵消的性质,以及影响移民结果的复杂途径。
