The impact of immigration enforcement on the U.S. farming sector

We examine the effects of local immigration enforcement efforts on U.S. agriculture in dozens of U.S. counties from 2002-2010 by using variations in the timing of adoption of 287(g) programs, which permit local police to enforce immigration law. Difference-in-differences models using microdata from the American Community Survey (2005-2010 waves) and county tabulations from the Census of Agriculture (1997, 2002, and 2007) yield robust evidence that county enforcement efforts have reduced immigrant presence in adopting jurisdictions. We also find evidence that wages of farm workers, patterns of farm labor use, output choices, and farm profitability may have been affected in a manner consistent with farm labor shortages.
