Labor Market Impacts of Trump 2.0 Immigration Enforcement

 The provided paper, "Labor Market Impacts of ICE Activity in Trump 2.0," by Elizabeth Cox and Chloe N. East, offers the first national, causal empirical analysis of how heightened immigration enforcement during the second Trump administration has affected the U.S. labor market. The study evaluates both the direct impact on undocumented immigrants and the spillover effects on U.S.-born workers, testing the common policy justification that removing immigrants expands job opportunities for native-born citizens.

Methodological Approach

The researchers utilized a natural experiment framework to isolate the effects of enforcement surges.

• Identification Strategy: While enforcement increased nationwide, it did so unevenly across different regions. The authors classified "treated" areas as those experiencing a sudden, large increase in ICE arrests (roughly a doubling) between January and October 2025, while "control" areas did not see such surges.
• Data Sources: The study combined administrative arrest data from the Deportation Data Project with worker-level labor market data from the Current Population Survey (CPS).
• Target Population: The analysis focused on "likely undocumented immigrants" (foreign-born, aged 20-64, with a high school degree or less) and U.S.-born workers in sectors where undocumented labor is over-represented, such as agriculture, construction, manufacturing, and wholesale.

Impacts on Likely Undocumented Immigrants

The study identifies a significant "chilling effect" among immigrants who remain in the U.S..

• Reduction in Work: Even if not physically removed, immigrants in treated areas reduced their work activity out of fear that being at a workplace could lead to ICE interactions. This led to a 4% reduction in employment among the likely undocumented sample.
• Gender Concentration: These effects were primarily driven by males, who accounted for over 85-90% of ICE arrests. Male employment in these sectors dropped by 4.6 percentage points (5%), and their weekly hours worked also fell by 5%.
• Comparison to Past Eras: The chilling effect in Trump 2.0 is notably larger than in previous administrations. The authors calculate that for every one ICE arrest, six male likely undocumented workers stop working. This is more than double the chilling effect observed during the Obama administration, which the authors attribute to the more indiscriminate nature of enforcement in Trump 2.0.

Impacts on U.S.-Born Workers

A central finding of the research is the lack of evidence that U.S.-born workers benefit from these enforcement surges.

• No Substitution: The authors rule out any increase in the U.S.-born employment rate in impacted sectors of more than 0.1 percentage points.
• Complementarity and Harm: Instead of taking the jobs left behind, certain U.S.-born groups were actually harmed. Less-educated U.S.-born men in likely affected sectors saw a 1.3% reduction in employment.
• Economic Mechanism: This suggests that undocumented and U.S.-born workers are complements rather than substitutes. When the supply of undocumented labor is disrupted, it appears to contract overall labor demand in those sectors rather than reallocate it to native workers. Furthermore, there was no evidence that employers raised wages to attract U.S.-born workers to fill vacancies.

Broader Context and Contribution

The study contributes to a growing body of literature on Trump 2.0 by linking national enforcement intensity directly to worker-level outcomes. It concludes that the policy of mass deportation and heightened interior enforcement may have the unintended consequence of harming the very U.S.-born workers it is intended to help by shrinking the labor market in key industrial sectors.

The sources describe the impact on likely undocumented immigrants during the second Trump administration as a significant "chilling effect" that reduces labor supply even among those who are not physically deported. This research provides the first national, causal empirical analysis of these labor market shifts, utilizing a natural experiment framework that compares geographic areas with sudden surges in ICE arrests to those without.

The "Chilling Effect" Mechanism

The study distinguishes between two channels of impact: physical removals and chilling effects. The latter occurs when heightened ICE activity causes individuals to remain in the U.S. but reduce their participation in regular activities—including going to work—out of fear that the workplace could be a site for ICE interactions.

Quantitative Impacts on Employment

The sources highlight several key findings regarding the scale of this impact:

• Overall Employment Reduction: Among likely undocumented immigrants remaining in the U.S. who work in affected sectors, there was a 4% reduction in employment.
• Gender Concentration: These effects are almost entirely driven by males, who represent over 85-90% of those arrested by ICE during the study period. For likely undocumented men, employment dropped by 5% (4.6 percentage points), and their weekly hours worked also fell by 5% (2 hours per week).
• Sector-Specific Impact: The strongest negative effects were observed in the construction sector, which has a high concentration of undocumented labor (over 15%).
• Impact on Wages: The study found no evidence of a consistent effect on pay (hourly wages or weekly earnings) for likely undocumented immigrants in high-impact sectors.

Magnitude and Historical Comparison

The sources quantify the intensity of the Trump 2.0 enforcement regime by comparing it to previous eras:

• The 6:1 Ratio: The authors calculate that for every one ICE arrest, six male likely undocumented workers stop working.
• Trump 2.0 vs. Obama Era: This chilling effect is more than double what was observed during the Obama administration, where roughly 2.3 workers stopped working per detention. The authors attribute this increase to the more indiscriminate nature of enforcement in Trump 2.0 compared to previous administrations.

Broader Labor Market Context

In the larger context of "Trump 2.0," these impacts do not lead to the intended policy goal of creating opportunities for native workers. Instead of U.S.-born workers substituting for the lost immigrant labor, the sources find that undocumented and U.S.-born workers are complements. When the supply of undocumented labor is disrupted, it leads to a contraction of overall labor demand in affected sectors, which ultimately harms less-educated U.S.-born male workers as well.

The study finds no evidence that heightened immigration enforcement in the "Trump 2.0" era expands job opportunities for U.S.-born workers. While a central policy justification for mass deportation is that it creates vacancies for native-born citizens, the researchers found a null effect on the full sample of U.S.-born individuals. Specifically, they were able to rule out any increase in the U.S.-born employment rate of more than 0.1 percentage points in sectors where undocumented labor is prevalent.

Negative Spillovers for Vulnerable Workers

Instead of benefiting from enforcement surges, certain groups of native workers were actually harmed. The sources highlight several key impacts:

• Impact on Less-Educated Men: The most significant negative effect was observed among U.S.-born male workers with a high school degree or less who work in immigrant-heavy sectors. This group saw a 1.3% reduction in their employment rate.
• Sector-Level Correlation: A clear relationship exists across industries: sectors that experienced the largest reductions in undocumented male employment (such as construction) also saw the most significant negative spillover effects for U.S.-born male workers.
• Quantified Loss: The authors calculate that for every six male likely undocumented workers who stop working, one male U.S.-born worker also loses their job.

The Mechanism of "Complementarity"

The researchers explain these negative outcomes through the economic concept of complementarity.

• Jobs are Linked: Rather than competing for the same roles, undocumented and U.S.-born workers often perform different, mutually dependent tasks within the same sector. For example, in construction, while both groups may work as laborers, the overall composition and concentration of their roles differ.
• Contraction of Demand: When the supply of undocumented labor is disrupted by ICE activity, it appears to contract overall labor demand in affected industries rather than reallocating existing jobs to native workers.
• No Wage Growth: The study found no evidence that employers responded to the loss of immigrant labor by increasing wages to attract U.S.-born workers to fill vacancies.

Broader Policy Implications

The findings suggest that the immigration enforcement regime in Trump 2.0 is more indiscriminate than in previous administrations, which amplifies these negative labor market consequences. By documenting these harmful spillovers, the sources conclude that heightened enforcement may ultimately undermine the economic prospects of the very U.S.-born workers it is intended to help.

In the context of the second Trump administration ("Trump 2.0"), the sources characterize the magnitude of immigration enforcement as a historic surge that is significantly larger and more indiscriminate than in recent decades. This intensified activity is measured through sudden, localized spikes in ICE arrests, which the authors use to quantify both the scale of the enforcement itself and its disproportionate impact on the labor supply.

Quantifying the Enforcement Surge

The research identifies a massive national increase in enforcement activity, though the intensity varied geographically.

• Arrest Volume: Following the second inauguration, total daily arrests surged from a baseline of approximately 300 to peaks exceeding 1,100 per day by late 2025.
• Treated Area Growth: Areas classified as "treated" experienced a sudden increase of roughly 200 daily arrests per month relative to control areas. This represented a 114% increase in arrests compared to the pre-period mean.
• Normalized Intensity: Adjusted for population, treated areas saw an increase of 94 arrests per 100,000 non-citizens.
• Gender Concentration: The magnitude of this surge was heavily concentrated among men, with 85% of the increase in total ICE arrests being driven by the arrest of males.

Comparative Magnitudes: Trump 2.0 vs. Prior Eras

The sources emphasize that the current enforcement regime is "much larger and more indiscriminate" than those of the 1930s or the 2010s.

• The Chilling Effect Multiplier: The magnitude of the "chilling effect"—where workers stop working due to fear of ICE interactions—is significantly higher in Trump 2.0 than during the Obama administration.
• Efficiency of Disruption: During the first Obama term, researchers found that for every person detained, roughly 2.3 likely undocumented workers stopped working. In Trump 2.0, this ratio has more than doubled: for every one ICE arrest, six male likely undocumented workers stop working.

Magnitude of Labor Market Disruption

The sheer scale of enforcement has led to substantial shifts in the workforce within treated regions.

• Total Worker Loss: The authors calculate that in the average treated area, there are approximately 7,574 fewer male likely undocumented workers in high-impact sectors like construction and agriculture.
• Impact on U.S.-Born Workers: The magnitude of the enforcement surge also creates a negative spillover for native-born citizens. For every six undocumented male workers who leave the labor force due to enforcement activity, one less-educated U.S.-born male worker also loses their job.
• Underestimation: The authors note that these figures likely underestimate the total economic impact, as their study focuses only on the "chilling effect" among those who remain in the U.S. and does not include the direct labor loss from physical removals and deportations.

The research presented in the paper "Labor Market Impacts of ICE Activity in Trump 2.0" leads to several key conclusions that challenge common political justifications for heightened immigration enforcement. Broadly, the authors conclude that the intensified ICE activity under the second Trump administration has contracted the labor market rather than reallocating jobs to native-born citizens.

1. Heightened Enforcement Creates a Massive "Chilling Effect"

A primary conclusion is that enforcement impacts the labor market far beyond physical removals. The study identifies a meaningful chilling effect where likely undocumented immigrants who remain in the U.S. reduce their work participation out of fear.

• Scale of the Effect: Among the likely undocumented sample in affected sectors, there was a significant 4% reduction in employment.
• The 6:1 Multiplier: The authors conclude that for every one ICE arrest, six male likely undocumented workers stop working.
• Comparison to Past Eras: This chilling effect is more than double what was observed during the Obama administration, which the authors attribute to the indiscriminate nature of enforcement in Trump 2.0.

2. No Evidence of Benefits for U.S.-Born Workers

The study directly addresses the policy justification that removing immigrants creates jobs for native-born workers and finds no evidence to support this claim.

• Null Overall Effect: For the full sample of U.S.-born individuals, the researchers found a null effect, ruling out any employment increase of more than 0.1 percentage points.
• No Wage Growth: There is no evidence that employers responded to labor shortages by increasing wages to attract U.S.-born workers.

3. Negative Spillovers and Harm to Vulnerable Native Workers

The authors conclude that instead of helping, the enforcement surge actually harmed certain segments of the U.S.-born population.

• Impact on Less-Educated Men: U.S.-born male workers with a high school degree or less in affected sectors saw a 1.3% reduction in their employment rate.
• Linked Job Loss: The data suggests a correlation where for every six lost male likely undocumented workers, one male U.S.-born worker also loses their job.

4. Economic Mechanism: Complementarity over Substitution

A central conclusion regarding the "why" of these results is that undocumented and U.S.-born workers are complements rather than substitutes.

• Production Interdependence: Because these workers often perform different but mutually dependent tasks, the loss of undocumented labor contracts overall labor demand in a sector.
• Sector-Level Correlation: The harm to U.S.-born workers was most pronounced in sectors like construction, which saw the largest drops in undocumented labor supply, further supporting the complementarity model.

Summary of the Broader Context

In the larger context of Trump 2.0, the authors conclude that the current enforcement regime is uniquely disruptive due to its scale and indiscriminate nature. They argue that the policy is undermining the economic prospects of the very workers it was intended to protect by shrinking the industrial sectors—such as agriculture and construction—that rely on a stable, multi-tiered workforce.
