Health worker migration is an issue of first order concern in global health policy circles and continues to be the subject of much policy debate. In this paper, we contribute to the discussion by studying the impact of economic conditions on the migration of physicians from developing countries. To our knowledge, this is one of the first papers to do so. A major contribution of this paper is the introduction of a new panel dataset on migration to the US and the UK from 31 sub-Saharan Africa countries. The data spans the period 1975-2004. Using this data, we estimate the impact of changes in economic conditions on physician migration. In our preferred specification that allows for country-specific time trends, we find that a temporary one percentage point decline in GDP per capita increases physician migration in the next period by approximately. 3 percent. In our IV models a one percentage point decline in GDP per capita increases physician migration in the next period by between 3.4 and 3.6 percent. Overall, our results suggest a significant effect of developing country economic conditions on physician migration.
卫生工作者迁移是全球卫生政策界首要关注的问题,也是政策辩论的主题。在本文中,我们通过研究经济条件对发展中国家医生迁移的影响,为这一讨论做出了贡献。据我们所知,这是第一篇这样做的论文之一。本文的一个主要贡献是引入了一个关于从 31 个撒哈拉以南非洲国家向美国和英国移民的新面板数据集。该数据涵盖了 1975-2004 年期间。使用这些数据,我们估计了经济条件变化对医生迁移的影响。在允许国家特定时间趋势的首选规格中,我们发现人均 GDP 临时下降一个百分点会使下一个时期的医生迁移增加约 0.3%。在我们的 IV 模型中,人均 GDP 下降一个百分点会使下一个时期的医生迁移增加 3.4%至 3.6%之间。总体而言,我们的结果表明,发展中国家的经济状况对医生迁移有重大影响。
