Immigrant earnings growth: selection bias or real progress?
利用加拿大移民登陆记录与纵向税收数据，研究发现移民与本地人的收入差距在纵向和横截面数据中缩小速度相同，低收入移民和本地人都会随时间退出样本，表明移民劳动力参与动态与本地人相似。
Abstract We use longitudinal tax data linked to immigrant landing records to study the effect of selective attrition on the estimated earnings assimilation of immigrants to Canada. Contrary to findings in the existing international literature, we show that the immigrant‐native earnings gap closes at the same pace in longitudinal and cross‐sectional data. Low‐earning immigrants are likely to leave the cross‐sectional samples over time, but the same is true for the native born. Our study suggests that immigrants to Canada have labour market participation dynamics similar to those of the native born.
