Brain Drain in Developing Countries
利用1990年和2000年按教育程度划分的国际移民数据，分析了发展中国家脑力流失的决定因素，发现小国、靠近OECD地区、有殖民联系及移民目的地有质量筛选计划的国家脑力流失更严重。
An original data set on international migration by educational attainment for 1990 and 2000 is used to analyze the determinants of brain drain from developing countries. The analysis starts with a simple decomposition of the brain drain in two multiplicative components, the degree of openness of sending countries (measured by the average emigration rate) and the schooling gap (measured by the education level of emigrants compared with natives). Regression models are used to identify the determinants of these components and explain cross-country differences in the migration of skilled workers. Unsurprisingly, the brain drain is strong in small countries that are close to major Organisation for Economic Co-operation and Development (OECD) regions, that share colonial links with OECD countries, and that send most of their migrants to countries with quality-selective immigration programs. Interestingly, the brain drain increases with political instability and the degree of fractionalization at origin and decreases with natives' human capital.
