TL;DR
The debate over how immigration affects domestic labor markets is undergoing a major empirical shift as researchers correct long-standing statistical biases and analyze a real-time contraction in immigration. Newly corrected economic models reveal that native workforce exits have historically masked downward wage pressures, while the current policy-driven slowdown in immigrant flows is simultaneously boosting low-skilled native employment and choking off expansion in key sectors like construction.
Methodological corrections expose the hidden wage costs of immigration
The long-held economic consensus that immigration does not depress native wages is unraveling as researchers correct for the self-selection of workers who exit the labor market in response to supply shocks.
"Adjusting for the selection bias results in a similar wage elasticity for both French men and women (between -0.8 and -1.0)." — selection-bias-native-employment-wage-impacts
In a study published in the Journal of Labor Economics, George J. Borjas and Anthony Edo argue that standard regional wage regressions are heavily contaminated by selection bias (hks.harvard.edu). When low-wage native workers drop out of the labor force in response to an immigrant influx, their exit artificially inflates the average wages of those who remain, masking the true downward pressure. By correcting for this compositional shift using a Heckman selection model, the authors reveal that the actual wage elasticity is negative and significant, and they estimate a female crowd-out parameter of approximately 0.55 selection-bias-native-employment-wage-impacts.
This methodological correction suggests that the apparent resilience of native wages in previous studies was a mathematical illusion rather than an economic reality. Reconciling the employment and wage impacts of immigration requires tracking not just continuously employed "survivors," but also the vulnerable workers who are pushed out of the labor force entirely.
What to watch: Watch for whether other major labor studies adopt Heckman selection models to re-evaluate wage elasticities in highly affected U.S. metropolitan areas.
The enforcement-led supply contraction creates a stark trade-off between native job gains and industrial bottlenecks
The sudden reversal of immigration flows is forcing a real-time choice between drawing marginalized domestic workers back into the labor force and starving key capital-heavy industries of essential labor.
"The sudden decline represents an opportunity for U.S. workers, who now face less competition from immigrant labor... Based on our view of the data, the theorized benefits of reduced immigration, such as drawing more low-skill natives back into the labor force, may be beginning to emerge." — immigration-enforcement-native-employment-impacts
"The effect for the construction sector is particularly notable, because it suggests that falling UIWF in recent months could be slowing residential construction and hence slowing down the growth of housing supply." — unauthorized-immigration-local-labor-and-housing-markets
In American Affairs, Steven A. Camarota and Jason Richwine document that the post-2025 enforcement push coincided with a rise of 412,000 employed native-born workers (americanaffairsjournal.org). However, research by Daniel Wilson and Xiaoqing Zhou in the FRBSF Economic Letter cautions that this contraction has triggered a nearly one-for-one drop in local employment within key sectors, with a 1% flow reduction leading to a 1.16% employment drop in affected areas (frbsf.org).
These divergent findings highlight the tension between the "substitution hypothesis" and the "complementarity trap." While restrictionist policies successfully coaxed some non-college native workers back into employment, they did not trigger a simple one-for-one replacement in heavy industries, instead bottlenecking construction and manufacturing.
What to watch: Watch for whether the growth rates of residential-exposed construction firms continue to slow as the labor supply constraint tightens.
What surprised us
- The compositional illusion of female wages: In France, the rapid "feminization" of the immigrant workforce—accounting for 75.6% of immigrant growth—appeared to have zero effect on native female wages, but this was entirely a statistical illusion caused by low-wage women dropping out of the workforce selection-bias-native-employment-wage-impacts

- The symmetry of local employment impacts: Despite intense debate over whether immigrants displace native workers or create new demand, Federal Reserve Bank of San Francisco researchers found a nearly one-for-one causal relationship between unauthorized immigrant flows and local employment unauthorized-immigration-local-labor-and-housing-markets
