This paper uses a natural experiment to identify the effects of immigration on the man-ufacturing industry and the Great Black Migration in the US between 1920 and 1930.The immigration quota system established in 1921 and 1924 severely restricted immigrants from southern and eastern Europe while imposing modest restrictions on western and northern Europe.Hence US regions that were historically major destinations of eastern and southern European immigrants experienced a greater exogenous decline in immigrant supply.I use the estimated number of excluded immigrants from each US region by the quotas as the instrumental variable for the change in the regional foreign-born share.I find that the negative immigrant supply shock to a US region significantly increased the regional manufacturing wage level and induced a greater inflow of native black migrants.I also find that manufacturers facing a greater decline in immigrant supply had a slower growth in production scale and electrification.
