Earnings and Mobility of Legal and Illegal Immigrant Workers in Agriculture
通过理论和实证证据表明，无证移民更可能从事低工资、低技能的农场工作，且在高技能农场工作中收入显著低于合法工人，合法化可能不会提高收入甚至导致部分岗位工资下降。
Abstract This paper presents theoretical and empirical evidence that unauthorized immigrants are more likely to be selected into low‐wage, low‐skill farm jobs than are otherwise similar legal workers. Controlling for this selection process, the earnings of unauthorized workers are significantly lower than the earnings of legal workers in high‐skill farm jobs. These findings are shown to be consistent with expected profit maximization by farm employers. Legalization of farmworkers under the Special Agricultural Worker (SAW) program is not likely to increase farmworker earnings and may result in wage decreases in some farm jobs.
