移民与最高收入的1%群体

中文摘要

摘要：利用涵盖英国全体纳税人的行政数据，我们研究了移民对英国最高收入群体收入份额上升的贡献。研究表明，移民在收入分布顶端的占比过高：移民在收入最高的0.01%纳税人中的占比，是其在收入最低97%纳税人中任一部分占比的两倍。这些高收入主要来自劳动而非资本，且移民集中于少数几个行业，其中以金融业为主。过去20年英国最高收入1%群体收入份额中观察到的全部增长，均归于移民。

Abstract

Abstract Using administrative data on the universe of U.K. taxpayers, we study the contribution of migrants to the rise in U.K. top incomes. We show that migrants are over-represented at the top of the income distribution, with migrants twice as prevalent in the top 0.01% as anywhere in the bottom 97% of taxpayers. These high incomes are predominantly from labor, rather than capital, and migrants are concentrated in only a handful of industries, predominantly finance. All of the observed growth in the U.K. top 1% income share over the past 20 years has accrued to migrants.
