TL;DR
The structural debate over immigration's economic footprint is being reshaped by new empirical evidence on selection bias, post-pandemic housing demand, and long-term task complementarity. While recent localized surges have expanded payrolls without depressing average wages, they have driven up shelter costs and triggered silent labor force exits among vulnerable native cohorts. Correcting for these compositional shifts reveals that immigration exerts real short-run wage pressures that are only gradually offset by occupational upgrading and capital adjustments over time.
Selection Bias and the Illusion of Wage Stability
Methodological blind spots in labor economics have historically masked the true downward pressure of immigration on native wages by ignoring how vulnerable workers exit the labor force.
"Adjusting for selection bias results in a wage elasticity that becomes negative for women and similar to men." — selection-bias-native-employment-wage-impacts
In a study published in the Journal of Labor Economics, researchers George J. Borjas and Anthony Edo demonstrate that when an immigrant supply shock occurs, competing native workers with elastic labor supply—such as women—frequently exit the labor force selection-bias-native-employment-wage-impacts. Because the workers who leave are disproportionately low-wage earners, their exit mechanically inflates the average wage of those who remain, hiding the negative wage impact in standard cross-sections selection-bias-native-employment-wage-impacts
. For native women, this crowd-out parameter is -0.51, meaning that five employed native women left the labor force for every ten new working immigrants, but correcting for this selection bias reveals a true wage elasticity between -0.7 and -0.9 (https://gborjas.scholars.harvard.edu/resource/jole2026).
This reveals that seemingly benign wage effects in raw data can actually hide significant labor market displacement. Policymakers who rely on uncorrected wage data are missing the silent retreat of low-wage native workers from the workforce.
What to watch: Watch whether future empirical literature adopts selectivity-corrected models to re-evaluate historical immigration shocks.
The Post-Pandemic Shock as a Dual Labor-Supply and Housing-Demand Event
The post-pandemic surge in unauthorized immigration acted as a highly efficient labor supply shock that expanded employment, but it simultaneously triggered severe inflationary pressures in localized housing markets.
"We find that unauthorized immigrant worker flows (UIWF) increased local employment approximately one-for-one, without significant declines in local wages." — unauthorized-immigration-local-labor-and-housing-markets
An empirical assessment by Daniel J. Wilson and Xiaoqing Zhou in Dallas Fed Working Paper 2607 reveals that during the 2021–2024 boom, unauthorized immigrant worker flows expanded total local employment by 0.96% for every proportional increase in local labor supply (https://www.dallasfed.org/~/media/documents/research/papers/2026/wp2607.pdf). However, because housing supply is highly inelastic in the short run, this influx drove up local house prices by 2.2% without prompting new construction unauthorized-immigration-local-labor-and-housing-markets. On the fiscal front, a Congressional Budget Office report estimates that while these immigrants contributed billions in taxes, they imposed a direct net cost of $9.2 billion on state and local budgets in 2023 (https://www.cbo.gov/publication/61464).
This dual-nature shock shows that the primary economic pressure of sudden immigration surges is felt in municipal infrastructure and housing markets rather than through direct job displacement. The rapid labor absorption prevents wage collapse but exacerbates localized cost-of-living crises.
What to watch: Watch how local rental and housing markets respond to the steep decline and negative net migration that began in early 2025.
The Long-Run Structural Case for Complementarity and Upgrading
When analyzed over decades, the direct competition between native and immigrant labor is largely neutralized by capital adjustments and occupational upgrading.
"We find a significant elasticity of complementarity between US natives and immigrants, which boosts natives' relative wages, as well as a positive employment response of natives to immigrants." — labor-economics-consensus-skill-groups-nasem
In NBER Working Paper 32389, economists Alessandro Caiumi and Giovanni Peri refine national factor-supply models to show that native and immigrant workers are not perfect substitutes within education-experience groups (https://www.nber.org/papers/w32389). Instead, native workers respond to immigrant inflows by specializing in communication-intensive and supervisory roles, which upgraded their occupational status and increased the wages of non-college-educated native workers by 2.6% to 3.4% labor-economics-consensus-skill-groups-nasem. On average, immigration boosted the wages of all native workers by 0.6% over the analyzed multi-decade period labor-economics-consensus-skill-groups-nasem
.
This structural perspective reconciles the tension between short-run localized shocks and long-run national trends. It demonstrates that the economy dynamically adapts to labor inflows through capital expansion and task specialization, protecting native-born earnings over time.
What to watch: Watch whether future policy proposals leverage these task-complementarity findings to design skill-selective immigration pathways.
What surprised us
- The Fiscal Paradox of Unauthorized Labor: While the CBO reported a net cost of $9.2 billion to state and local governments for services like education and emergency shelters, the Dallas Fed study discovered that unauthorized inflows actually reduced per capita local government transfer payments by 5.0% unauthorized-immigration-local-labor-and-housing-markets
. This reduction occurs because the positive employment shock lowers local eligibility for safety net programs, and unauthorized workers are largely ineligible for these transfers.
- Hidden Workforce Flight: Standard wage correlations for female native workers showed a positive relationship (+0.19) with immigration, suggesting no harm, but this was entirely a mirage caused by selection bias selection-bias-native-employment-wage-impacts
. Once Borjas and Edo corrected for the fact that low-wage women were pushed out of the workforce entirely, the true wage impact emerged as deeply negative selection-bias-native-employment-wage-impacts
- The Housing Premium: Unauthorized immigration accounted for a massive 30% of the total growth in house prices and 20% of rent growth in the average metropolitan area during the post-pandemic surge unauthorized-immigration-local-labor-and-housing-markets
