"A methodology is devised for the empirical analysis of the determinants of outmigration of immigrants in a population. Empirical studies in this area have been hindered by a lack of longitudinal data on the characteristics of the immigrants. This problem is tackled by making use of cross-sectional data at two points in time. It is applied to the study of male immigrants in the United States. It is found that education is positively related to the rate of outmigration for immigrants from Canada, Asia and the pooled sample of immigrants. This finding suggests that the cross-sectional estimates of the growth in earnings of immigrants in the United States are underestimated for these groups of immigrants."
设计了一种方法,用于对人口中移民的迁出决定因素进行实证分析。该领域的实证研究因缺乏关于移民特征的纵向数据而受阻。通过利用两个时间点的横截面数据来解决这个问题。它被应用于对美国男性移民的研究。研究发现,教育与来自加拿大、亚洲的移民以及移民汇总样本的迁出率呈正相关。这一发现表明,对于这些移民群体,美国移民收入增长的横截面估计被低估了。
