The Selection of High-Skilled Emigrants
利用预测收入衡量德国高技能移民的选择性，发现移民到更不平等国家的是正向选择，到更平等国家的是负向选择，且正向选择与大学质量和成绩相关，负向选择与学科和性别相关。
Abstract We measure selection among high-skilled emigrants from Germany using predicted earnings. Migrants to less equal countries are positively selected relative to nonmigrants, while migrants to more equal countries are negatively selected, consistent with the prediction in Borjas (1987). Positive selection to less equal countries reflects university quality and grades, and negative selection to more equal countries reflects university subject and gender. Migrants to the United States are highly positively selected and concentrated in STEM fields. Our results highlight the relevance of the Borjas model for high-skilled individuals when credit constraints and other migration barriers are unlikely to be binding.
