Right here we examine the financial results of a large-scale experiment in america: the pure, nationwide, firm-level randomization of restrictions on the employment of immigrants for low-skilled jobs. America has a major work visa for low-skilled labor within the nonfarm economic system: the H-2B visa. Entry to this visa for US employers is restricted by a quota and awarded partly by way of a random lottery performed by the federal authorities. This exogenous variation in immigrant employment restrictions permits for unusually clear and policy-relevant estimates of how American corporations and employees are adjusting. After publicly participating in our speculation testing and predicting remedy results with a pre-analysis design, we collected knowledge from 2021 H-2B visa lottery winners and losers in a brand new survey of firms. This permits predefined checks of primary theoretical predictions concerning the magnitude and heterogeneity of the impact of restrictions on the immigration of low-skilled folks. It additionally permits estimation of the “mixed” immigrant-native elasticity of substitution on the agency stage (Hicks 1936).
We discover that exogenous permission to make use of immigrants for low-skilled labor causes the marginal agency to extend its output. In different phrases, the exogenous restrictions on the employment of the variety of immigrants maximizing the revenue for low-skilled labor result in the contraction of the marginal agency. These restrictions result in a big and statistically important drop in revenue and funding. The restrictions result in no improve, or lower, within the employment of low-skilled indigenous employees and the speed of revenue. Dropping the lottery reduces the employment of low-skilled immigrants in firms by 56%. This decline causes companies to contract, shrinking operations with an elasticity of +0.164 for income and +1.03 for funding (statistically distinguishable from zero at standard ranges), and with an elasticity of +0.102 for low-skilled American employment, and +0.100 for the speed of revenue (statistically indistinguishable from zero at standard ranges).
That is by Michael A. Clemens & Ethan G. Lewis,”The Impact of Low-Expert Immigration Restrictions on American Corporations and Employees: Proof from a Random Lottery“, NBER Working Paper No. 30589, October 22, 2022.
The methodology is sort of intelligent. As a result of fortunate employers are chosen by lottery, there isn’t a choice bias. Which means that Clemens and Lewis can look at job adjustments for employers who received the lottery and job adjustments for employers who misplaced.
The authors put it extra succinctly of their summary:
Corporations exogenously allowed to make use of extra immigrants considerably improve output (elasticity +0.16) with no lower or improve in US employment (elasticity +0.10, statistically imprecise) in a number of subsamples pre-recorded. The outcomes suggest very low substitutability of home labor with international labor in policy-relevant occupations.
In brief, low-skilled Individuals are usually not shedding their jobs to low-skilled immigrants.
