THE IMPACT OF IMMIGRATION ON THE STRUCTURE OF WAGES: THEORY AND EVIDENCE FROM BRITAIN
研究了英国过去30年移民增加对工资的影响，发现移民主要降低了移民自身（尤其是高学历移民）的工资，而对本土工人工资影响很小，原因是本土与外国工人不完全替代。
Immigration to the UK, particularly among more educated workers, has risen appreciably over the past 30 years and as such has raised labor supply. However studies of the impact of immigration have failed to find any significant effect on the wages of native-born workers in the UK. This is potentially puzzling since there is evidence that changes in the supply of educated natives have had significant effects on their wages. Using a pooled time series of British cross-sectional micro data on male wages and employment from the mid-1970s to the mid-2000s, this paper offers one possible resolution to this puzzle, namely that in the UK natives and foreign born workers are imperfect substitutes. We show that immigration has primarily reduced the wages of immigrants- and in particular of university educated immigrants- with little discernable effect on the wages of the native-born.
