The user's brief asks us to:
- Adjudicate what credible evidence says about how immigration affects native wages and employment.
- Track new empirical research and replications, with close attention to method, sector- and skill-specific findings rather than aggregates.
- Look at sectors where the effect is most studied (construction, agriculture, hospitality, tech/H-1B).
- Look at major policy changes that create natural experiments.
- Distinguish short-run from long-run and skill-group from average effects.
Let's do some searches. Specifically, I want to see if there are any new papers, particularly in 2025 or 2026, or classic papers focusing on sector-specific impacts (construction, agriculture, hospitality, tech/H-1B) and policy changes/natural experiments.
Let's search for recent papers on "immigration wage effects sector construction agriculture" or "H-1B native wages tech" or other natural experiments.
Let's start by searching for papers on H-1B visa effects on native wages and employment, or agriculture/construction immigration wage effects. Let's do a general search first.

This is absolutely fantastic! It provides recent empirical evidence from 2024 and 2025 regarding high-skilled immigration (H-1B visa program), specifically studying the causal effects of hiring high-skilled immigrants on firm performance, native displacement, and offshoring using the H-1B lottery as a natural experiment.
Let's look at the key papers cited here:
1. **Morales et al. (2024 Working Paper / Census Working Paper 2024)**: "The Impact of Immigration on Firms and Workers: Insights From the H-1B Lottery" (co-authored by Agostina Brinatti, Mingyu Chen, Parag Mahajan, Kevin Shih, and Nicolas Morales).
- *Design*: Utilizes the random variation of the H-1B lottery.
- *Findings*: Winning firms expand employment and revenues, and are more likely to survive. No evidence that hiring H-1Bs displaces native college-educated workers. Small, high-productivity firms are the biggest winners, hiring *more* native graduates once they bring in immigrant talent (complementarity).
2. **Morales (2025 RESTUD / REStat paper)**: "High-Skill Migration, Multinational Companies and the Location of Economic Activity" (published in *Review of Economics and Statistics*).
- *Findings*: A permanent 10% reduction in college-educated immigrants lowers annual welfare for U.S. natives by $2.9B. Native college graduates compete more directly and face some wage pressure, but these are outweighed by broader benefits (complementarity, lower consumer prices).
3. **Glennon (2023 Management Science / paper)**: "How Do Restrictions on High-Skilled Immigration Affect Offshoring? Evidence From the H-1B Program".
- *Findings*: Under H-1B restrictions, firms increasingly shift operations offshore, especially to India and Canada.
4. **Brinatti & Guo (2023 Bank of Canada working paper)**: "Third-Country Effects of U.S. Immigration Policy".
- *Findings*: Skilled workers failing to secure H-1Bs relocate to Canada, bolstering its IT sector.
Let's also search for other new papers on low-skilled immigration, agriculture, or construction, and check if there are any other recent meta-analyses or natural experiments.
Wait, let's search for "immigration wage effects agriculture construction 2025 2026" or "immigration employment effects construction native" to see if there are other relevant studies.

This is an incredibly rich, 2026-fresh finding!
Let's analyze what we have:
Daniel Wilson (SF Fed) and Xiaoqing Zhou (Dallas Fed) published a Federal Reserve Bank of San Francisco Economic Letter (2026-05) on February 17, 2026, titled "Unauthorized Immigration Effects on Local Labor Markets."
They use a brand-new data set on "unauthorized immigrant worker flows" (UIWF) constructed from individual-level immigration court data from TRAC linked with state-level unemployment insurance administrative records (the Bureau of Labor Statistics' Census of Employment and Wages - CEW).
Let's summarize their key methodological innovations and empirical findings:
1. **Methodology**:
- They construct "unauthorized immigrant worker flows" (UIWF) at the county and commuting zone level, adapting the classic Card (2001) "shift-share" (or enclave) instrument to isolate *supply-driven* immigrant inflows from local *demand-driven* pull factors.
- They define the "rapid rise" period as March 2021 to March 2024 and the "slowdown" period as March 2024 to March 2025.
2. **Empirical Findings on Employment**:
- They find a nearly **one-for-one** causal effect of UIWF on local employment growth in both periods.
- Specifically, an increase in UIWF equal to 1% of local employment raises local employment by **0.92%** (SE 0.17) in the rapid rise period and **1.16%** (SE 0.49) in the slowdown period.
- This suggests that any positive local multiplier effects (from increased consumption/demand for services) and negative crowd-out/displacement effects on native workers roughly offset each other, resulting in a net aggregate employment effect of ~1.0.
3. **Sector-Specific Effects**:
- **Rapid Rise (March 2021 – March 2024)**: The influx of unauthorized immigrant workers had particularly large, disproportionate positive employment effects in **leisure and hospitality, professional services, and other services**.
- **Slowdown (March 2024 – March 2025)**: The subsequent slowdown in unauthorized immigration had particularly large, disproportionate negative employment effects in **construction, manufacturing, and other services**.
- The authors note that the slowdown in the **construction sector** is especially important because it could be slowing residential construction and thus restricting the growth of housing supply.
Let's also pull the Dallas Fed Working Paper 2607 to see if there is more details about wage effects. The abstract of Dallas Fed Working Paper 2607 says "We find no significant effects on industry-specific wages. We also extend the labor market analysis..."
Let's search for "The Impacts of Unauthorized Immigration on U.S. Labor and Housing Markets: New Evidence from Administrative Microdata" to find its exact text or details of its wage findings. Let's do a search.

This is a spectacular paper. It provides a complete, 2026-fresh, scrupulously neutral, and empirical analysis of the post-pandemic unauthorized immigration surge and its subsequent decline.
Let's look at the sectors we need to report on:
1. **Construction**:
- The paper notes that during the slowdown (March 2024–March 2025), the decline in unauthorized immigration had a disproportionately large negative impact on local employment growth in **construction**, manufacturing, and other services.
- The authors point out: "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."
- On the quantity side of housing, the paper finds that during the boom period, UIWF acted primarily as a housing demand shock rather than a supply shock, with small and statistically insignificant effects on new housing permits.
2. **Agriculture**:
- Let's search if there is any other recent paper or if we should check our existing notes or other web sources for agriculture-specific findings.
3. **Hospitality/Leisure**:
- The paper shows that during the boom period (March 2021–March 2024), unauthorized immigrant worker flows had a particularly large, disproportionately positive employment effect on **leisure and hospitality, professional services, and other services**.
4. **Tech / H-1B**:
- We got the Richmond Fed Economic Brief 2025-39 "Understanding the Potential Impact of H-1B Visa Program Changes" by Nicolas Morales (October 2025) and Morales et al. (2024) working paper "The Impact of Immigration on Firms and Workers: Insights from the H-1B Lottery".
- This paper uses the H-1B lottery as a natural experiment.
- Key findings: Firms that win the H-1B lottery expand employment and revenues, and are more likely to survive. Crucially, there is no evidence of native college-educated worker displacement. Instead, small, high-productivity firms are the biggest winners, hiring *more* native-born college graduates once they bring in immigrant talent.
- Also, high-skill immigration restrictions push production abroad (offshoring to India, Canada) and lead to third-country effects (with failed H-1B applicants relocating to Canada). A permanent 10% reduction in college-educated immigrants would lower annual welfare for U.S. natives by $2.9 billion.
Let's also pull public market data for sectors like Construction and Agriculture, as requested by the public markets guidelines.
Guidelines say: "This topic has the public-markets datasource. When it concerns a company, sector, or the macro backdrop, your FIRST research step is to call `market_view` to pull the cited figures, then write findings grounded in them... sectors: agriculture (Agriculture), chemicals (Chemicals), construction (Construction), energy (Energy), food-beverage (Food & Beverage), metals-mining (Metals & Mining), real-estate (Real Estate)".
Let's call `market_view` for Construction, Agriculture, and also macro backdrop. Let's do that! This is a great way to anchor the analysis with current market realities.

Excellent! Now let's review our findings and see how we can write or update findings to match the new empirical evidence.
First, let's look at the existing notes:
1. `labor-economics-consensus-skill-groups-nasem` (Labor Economics Consensus: Skill-Group Effects and the NASEM Report)
2. `cepii-meta-analysis-wage-effects-immigration` (CEPII Meta-Analysis (2025): The Comprehensive Wage Effects of Immigration)
3. `mariel-methodological-reconciliation-compositional-bias` (Methodological Reconciliation of Mariel: Compositional Bias and the Role of Race)
4. `immigrant-induced-demand-shocks-norwegian-evidence` (The Labor Supply Curve is Upward Sloping: The Effects of Immigrant-Induced Demand Shocks)
5. `mariel-boatlift-debate-card-borjas` (The Mariel Boatlift Debate: Card's No-Effect Finding vs. Borjas's Reanalysis)
Wait! The user's brief asks us to:
"Weigh studies on their designs, distinguish short-run from long-run and skill-group from average effects, and say what's genuinely established versus contested... I want to track new empirical research and replications with close attention to method, sector- and skill-specific findings rather than aggregates, and major policy changes that create natural experiments."
Let's look at what we can update or add:
1. We have a major new empirical break-through on **unauthorized immigration** from the Dallas Fed and SF Fed (Wilson & Zhou, March 2026/February 2026).
- The paper specifically studies the post-pandemic unauthorized immigration surge (March 2021–March 2024) and the subsequent slowdown (June 2024–June 2025).
- They find a **one-for-one** effect of unauthorized immigrant worker flows (UIWF) on local employment growth, both in the boom and the slowdown.
- They find **no significant impact on local wages** in the aggregate.
- However, they find a **significant negative effect on per capita labor income** due to downward wage composition (unauthorized workers earn less on average).
- They find that UIWF acted as a **housing demand shock**, increasing house prices by 2.2% and rents by 1.4% for each 1% of initial employment in UIWF, with no significant effect on housing supply (permits).
- They find a **significant negative effect on government transfers**, showing that immigration actually reduced transfer payments per capita (by ~5% for a 1% UIWF increase), likely because of higher employment and lower eligibility/utilization of welfare among work-age unauthorized immigrants.
- Industry-specific findings: The boom disproportionately increased employment in **leisure and hospitality**. The slowdown disproportionately reduced employment in **construction and manufacturing**.
Let's write a new finding or update an existing one. Wait, is there an existing note on unauthorized immigration or post-pandemic immigration?
Let's check the list of notes again:
- `labor-economics-consensus-skill-groups-nasem`
- `cepii-meta-analysis-wage-effects-immigration`
- `mariel-methodological-reconciliation-compositional-bias`
- `immigrant-induced-demand-shocks-norwegian-evidence`
- `mariel-boatlift-debate-card-borjas`
There is no note specifically tracking **unauthorized immigration** or the **post-pandemic immigration surge**.
This is a massive, highly relevant, and durably named subject! A perfect stable slug for this would be `unauthorized-immigration-local-labor-and-housing-markets` or `post-pandemic-unauthorized-immigration-surges`. Let's name it `unauthorized-immigration-local-labor-and-housing-markets`.
Wait, let's also look at high-skilled immigration/H-1B visa program changes, since there is a major new policy proposal (the $100,000 fee proposed in late 2025) and new research (Morales et al., 2024; Morales, 2025; Glennon, 2023; Brinatti & Guo, 2023). This is another massive subject: high-skilled immigration, firm-level effects, and H-1B lottery natural experiments. Let's create a finding for this with a stable slug like `high-skilled-immigration-h1b-lottery-and-firm-performance`.
Let's write these two notes!
Wait, let's double check if there are other papers we should search for first, or if we have enough material.
For `unauthorized-immigration-local-labor-and-housing-markets`, we have the 2026 Dallas Fed Working Paper 2607 and the 2026 SF Fed Economic Letter 2026-05 by Daniel Wilson and Xiaoqing Zhou. This is incredibly rich, detailed, and contains direct quotes and links.
For `high-skilled-immigration-h1b-lottery-and-firm-performance`, we have the Richmond Fed Economic Brief 2025-39 by Nicolas Morales (October 2025) which cites Morales et al. (2024), Morales (2025), Glennon (2023), and Brinatti & Guo (2023).

Let's outline our two findings:
1. **Finding 1: Post-Pandemic Unauthorized Immigration Surge and its Labor and Housing Market Impacts**
- **Slug**: `unauthorized-immigration-local-labor-and-housing-markets`
- **Content**:
- Introduce the unprecedented post-pandemic unauthorized immigration boom (March 2021–March 2024) and the subsequent rapid slowdown (June 2024–June 2025).
- Methodology: Daniel Wilson (SF Fed) and Xiaoqing Zhou (Dallas Fed) construct a novel dataset of "unauthorized immigrant worker flows" (UIWF) from individual-level immigration court data (TRAC) and state unemployment insurance filings (QCEW). They use a two-way leave-out shift-share instrument to establish causal effects.
- Labor Market Impacts: UIWF increased local employment approximately **one-for-one** (0.96% increase in employment for 1% UIWF increase), without significant declines in local average weekly wages.
- Income and Fiscal Effects: It reduced *per capita* labor income (compositional effect because unauthorized workers earn lower wages on average) and **strongly reduced government transfers** (both in total and per capita), indicating that the work-age influx boosted employment and reduced reliance on social safety nets (unemployment insurance, SNAP, Medicaid).
- Sector-Specific Impacts: During the boom, employment grew disproportionately in **leisure and hospitality**. During the slowdown, employment slowed disproportionately in **construction and manufacturing**. In construction, this is particularly critical because it slows residential construction and housing supply growth.
- Housing Market Impacts: UIWF acted as a housing demand shock, raising house prices by 2.2% and market rents by 1.4% for each 1% of initial employment in UIWF, with no significant effect on housing supply (permits).
- Connect with public markets: The Construction sector `/markets/sector/construction/2026/06/15` (e.g., Martin Marietta Materials [MLM] and Vulcan Materials [VMC], which supply aggregates) and the macro backdrop `/markets/macro/2026/06/15` (with the unemployment rate at 4.3% and the CPI index at 333.979) are directly linked to these dynamics.

- **Content**:
- Analyze the impact of high-skilled immigration using the H-1B lottery as a natural experiment, drawing on Nicolas Morales's October 2025 Richmond Fed Economic Brief and Morales et al. (2024) working paper.
- Firm-Level Growth: Winning the H-1B lottery allows firms to expand employment and revenues, and increases their survival rates.
- Native Complementarity vs. Displacement: Crucially, hiring H-1B workers does not displace native college-educated workers. Instead, small, high-productivity firms are the primary beneficiaries, hiring *more* native-born graduates once they secure immigrant talent (complementarity).
- Offshoring and Relocation: Restricting high-skilled immigration doesn't protect native jobs; instead, it pushes firms to offshore operations to countries like Canada and India (Glennon, 2023) or causes skilled workers who fail to secure visas to relocate to Canada, boosting its IT sector (Brinatti & Guo, 2023).
- Policy Impact: A late 2025 proposal to impose a $100,000 fee for H-1B visas would severely impact lower-wage tech workers, IT services, and nonprofits/universities, while shifting the remaining pool toward higher-wage, higher-skill roles.
- Source citations and verbatim quotes.

This is excellent. We have written two extremely robust, detailed, and scrupulously neutral notes grounded in the latest 2025 and 2026 empirical evidence.
Let's review if there are any other open threads or watches we need to record.
Let's register a watch for the H-1B visa fee proposal or further data on unauthorized immigration flows.
Wait, let's see: the H-1B $100,000 visa fee proposal was announced in late 2025 by the White House. It's a major policy change that would create a massive natural experiment. We should register a watch to monitor whether this $100,000 H-1B visa fee policy is implemented or legally challenged in 2026. This is a perfect dated catalyst or live process watch.
Let's record a watch for this:
- Title: `Implementation or legal ruling on the proposed $100,000 H-1B visa fee`
- Cardinality: `one_shot`
- Watch Type: `live_process`
- Note: `Watch for final implementation rules, court challenges, or administrative blocks on the proposed $100,000 H-1B processing fee.`

I have completed the research cycle for topic `019e89d0-1359-70a2-95cf-80adebbdd875`. Here is a summary of the findings and updates established in this cycle:
### 1. New Findings on Unauthorized Immigration and Local Labor and Housing Markets
I have documented cutting-edge empirical research from a March 2026 Dallas Fed Working Paper and a February 2026 San Francisco Fed Economic Letter by economists Daniel J. Wilson and Xiaoqing Zhou. This research provides the first systematic cross-sectional assessment of the post-pandemic unauthorized immigration surge (March 2021–March 2024) and subsequent decline (June 2024–June 2025):
* **One-for-One Employment Growth:** Inflows of unauthorized immigrant workers (UIWF) increased local nonfarm employment roughly **one-for-one** (a 1% increase in UIWF relative to initial employment raised local employment by **0.96%**).
* **Muted Wage Impacts:** There is **no evidence** that the surge depressed aggregate local weekly wages. However, it significantly reduced **per capita labor income** due to downward wage composition (unauthorized workers earn lower wages on average).
* **Housing Demand Shock:** Because housing supply is highly inelastic in the short run, the surge acted as a demand shock, raising local **house prices by 2.2%** and **market rents by 1.4%** for each 1% increase in UIWF relative to initial employment, with no significant impact on new building permits.
* **Fiscal Benefits:** UIWF **strongly reduced government transfers** (by **4.5%** in total and **5.0%** per capita), as higher employment reduced eligibility and reliance on local safety net programs (unemployment insurance, SNAP, Medicaid).
* **Sector-Specific Slowdowns:** While the boom disproportionately boosted **leisure and hospitality** employment, the subsequent 2024–2025 slowdown disproportionately hurt **construction and manufacturing** employment. The slowdown in construction is particularly critical as it restricts residential building capacity and housing supply growth.
This is tracked under the new stable slug: `[[unauthorized-immigration-local-labor-and-housing-markets]]`.
### 2. New Findings on High-Skilled Immigration and Firm-Level Complementarity
I have captured recent research utilizing the H-1B lottery as a natural experiment, including a prominent 2024 Census/IZA study and a 2025 Richmond Fed Economic Brief by Nicolas Morales:
* **Firm-Level Expansion:** Winning the H-1B lottery allows firms to expand employment and revenues, and increases their survival rates.
* **Native Complementarity:** Sponsoring H-1B workers does **not** displace native college-educated workers. Instead, small, high-productivity firms hire **more native-born graduates** once they secure specialized immigrant talent.
* **Offshoring Acceleration:** Restricting high-skilled immigration pushes multinational firms to **offshore operations** to subsidiaries in Canada and India (Glennon, 2023) or causes failed applicants to relocate to Canada, boosting its IT sector (Brinatti & Guo, 2023).
* **Impact of the Proposed $100,000 H-1B Fee:** A late 2025 White House proposal to impose a $100,000 processing fee on H-1B visas would severely impact lower-wage IT roles and nonprofits/universities (where median wages are only $64,610), while shifting the remaining pool toward ultra-high-wage roles and increasing offshoring incentives.
This is tracked under the new stable slug: `[[high-skilled-immigration-h1b-lottery-and-firm-performance]]`.
### 3. Forward-Looking Watches
To monitor these developments in future cycles, I have registered:
* A **live process watch** (`one_shot`) to track final implementation rules, administrative delays, or court challenges regarding the proposed **$100,000 H-1B visa processing fee**.
* A **scheduled release watch** (`ongoing`) to monitor updated annual net immigration estimates from the **CBO and DHS** for 2026.
