中文摘要

我们研究冲突引致的流离失所对人力资本与职业转换的影响,重点关注莫桑比克内战(1977—1992 年),其间数百万平民被迫逃往农村、城市和邻国。通过重建幸存人口的战时流动史,我们在一个统一框架下考察多种流离失所轨迹的后果。第一,我们刻画了全体流离失所者与非流离失所者的教育与部门就业状况。第二,我们利用扩展亲属成员在其求学期间迁移轨迹的差异。流离失所与教育的显著提升相关。第三,采用迁移者设计(movers design),我们发现,较早迁移到更好地区的未成年人获得了更高的教育成就。当聚焦于战争加剧期间的迁移、并在同一家庭内部成员之间进行比较时,地区性童年暴露效应依然很强,而空间排序效应变得可以忽略。第四,我们联合估计基于地域的效应、空间排序效应与背井离乡效应,结果表明所有作用力都在发挥作用。第五,在莫桑比克北部最大城市开展的一项小规模调查揭示了长期效应:国内流离失所者报告的教育水平高于留守原地的兄弟姐妹,但相对于当地人,其社会资本更低、心理健康状况更差。我们的研究结果表明,即使在极低收入环境下,流离失所冲击也能促进人力资本积累,尽管其代价是持久的社会与心理创伤。

Abstract

Abstract We study the effect of conflict-induced displacement on human capital and occupational shifts, focusing on the Mozambican civil war (1977–1992), during which millions of civilians were forced to flee to the countryside, cities, and neighboring countries. Reconstructing the wartime mobility histories of the surviving population, we examine the consequences of multiple displacement trajectories in a unified framework. First, we characterize the education and sectoral employment of the universe of (non-)displaced. Second, we exploit differences in relocation trajectories among extended kin members during their schooling years. Displacement is associated with significant gains in education. Third, using a movers design, we show that minors displaced earlier to better districts experienced an increase in educational attainment. Focusing on moves during the intensification of the war and when comparing members of the same household, regional childhood exposure effects remain strong, whereas spatial sorting becomes negligible. Fourth, we jointly estimate place-based, spatial sorting, and uprootedness effects, showing that all forces are at play. Fifth, a small survey in Mozambique’s largest northern city reveals long-term effects: internally displaced people report higher education than their siblings who stayed behind but lower social capital and worse mental health relative to locals. Our findings demonstrate that displacement shocks can foster human capital accumulation, even in very low-income settings, albeit at the cost of enduring social and psychological traumas.
