While economists know a lot about the socio-economic effects of international migration on the destination countries, the long-term impact of migration on source countries remains unclear and difficult to measure due to data limitation and selection issues. Because only the most able and entrepreneurial migrate, there are economic losses to countries of origin. On the other hand, migrants may send remittances and may return to their home countries with new skills that boosts economic development. This research project will use a unique archival data on international migration merged with data on contemporary economic conditions in source countries and innovative methodology to study the effects of international migration on source countries. The unique historical data, combined with the innovative research methods will allow the researchers to overcome the selection problems in the studies of migration. The results of this research project provide a better understanding of the benefits of international migration to both source and destination countries. The results will also inform migration policies in both source and destination countries.This DDRIE uses a combination of local level historical and contemporary data to study the effects of international emigration on source regions. To construct the independent variable, the researchers will collect and digitize individual conscripted soldier files containing detailed information such as their place of birth, year of birth, station of deployment and regiment of assignment, for each soldier who ever served in the army from archival sources. The research measures economic development at the local level using census data, satellite data and the Demographic and Health Surveys (DHS). Preliminary results suggest that conditional on the total number of soldiers enlisted in the army, the number of soldiers who were conscripted is strongly positively correlated with the several measures of current economic development and high emigration rates from source regions. The results of this research project will provide a better understanding of the mechanisms through which international migration occur as well as the benefits of such migration to both source and destination countries. The results will also inform migration policies in both source and destination countries.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

尽管经济学家对国际移民对目的地国家的社会经济影响非常了解，但由于数据限制和选择问题，移民对来源国家的长期影响仍然不清楚和难以衡量。因为只有最有能力和最企业家的迁移，因此对原籍国造成了经济损失。 另一方面，移民可能会发送汇款，并以新技能促进经济发展的新技能返回其本国。 该研究项目将使用有关国际迁移的独特档案数据与来源国家的当代经济状况和创新方法合并的数据，以研究国际移民对来源国家的影响。 独特的历史数据，结合创新的研究方法将使研究人员能够克服迁移研究中的选择问题。 该研究项目的结果可以更好地了解国际移民到来源和目的地国家的好处。 结果还将为来源和目的地国家 /地区的移民政策提供信息。该DDRIE结合了地方一级的历史和当代数据来研究国际移民对来源地区的影响。为了构建独立变量，研究人员将为每位曾经从档案资料中服役的士兵，收集和数字化各个被征召入伍的士兵文件，其中包含详细信息，例如出生地点，出生年份，部署和任务团。 该研究使用普查数据，卫星数据以及人口统计和健康调查（DHS）来衡量地方一级的经济发展。 初步的结果表明，符合军队中士兵的总数，被宪法的士兵人数与当前经济发展的多种措施和来自来源地区的高移民率密切相关。 该研究项目的结果将更好地了解国际移民发生的机制，以及这种迁移到来源和目的地国家的好处。 结果还将为来源和目的地国家 /地区的移民政策提供依据。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来评估值得支持的。
