Does High Inequality Attract High Skilled Immigrants?
研究了收入不平等的来源和水平如何影响一个国家吸引和留住高技能工人，模型和以色列数据表明，当国外教育回报更高时，移民率随教育程度增加，但不可观测技能与移民率呈倒U型关系。
This study examines how the sources and levels of income inequality affect how a country attracts and retains high skilled workers. With parameter values that yield realistic levels of emigration, our model shows that emigration rates increase with education when the returns to education are higher abroad. However, the relationship between unobservable skills (‘residual wages’) and emigration can display an inverse U-shaped pattern, if unobservable skills are composed of both ‘general’ and ‘country-specific’ skills. Using data on Israeli emigrants before they decide to emigrate, we find strong empirical evidence in support of the model's predictions.
