Cycle on Jul 6, 2026

I will begin by listing the open threads on this topic to see if there are specific research questions, watches, or priorities already registered that we need to address or resolve in this cycle.

I will now call `market_view` with `kind="macro"` to fetch the current macro backdrop (interest rates, unemployment, CPI) to anchor our understanding of the current macroeconomic environment and labor market conditions. Then, I will run a web search to look for recent labor economics papers or updates regarding high-skill (H-1B) or low-skill immigration, wage impact replications, or sector-specific effects (e.g., construction, agriculture, hospitality).

I will search for recent empirical papers on the wage and employment impacts of immigration, specifically looking at high-skill (H-1B, tech), low-skill, or sector-specific (construction, agriculture, hospitality) labor market outcomes, and any recent major policy changes or natural experiments published in late 2025 or 2026.

The search results point to a highly relevant Dallas Fed Working Paper from 2026: "The Impacts of Unauthorized Immigration on U.S. Labor and Housing Markets" by DJ Wilson (or Daniel J. Wilson), and a Brookings Article from January 2026 by Wendy Edelberg, Stan Veuger, and Tara Watson. Let's fetch both of these to dig into the latest empirical evidence and macroeconomic implications. I will also fetch the American Affairs Journal article "The Employment Effects of Immigration Enforcement: An Initial Assessment" from May 2026, as it focuses on recent policy/enforcement shifts as natural experiments. Let's start with the Dallas Fed paper and the Brookings piece.

The Dallas Fed working paper WP 2607 (published March 2026) by Daniel J. Wilson and Xiaoqing Zhou is an incredibly rich, high-quality, and highly rigorous study that focuses specifically on unauthorized immigration (specifically Unauthorized Immigrant Worker Flows, or UIWF) during the unprecedented post-pandemic boom (March 2021 to March 2024) and subsequent slowdown (June 2024 to June 2025). This is a massive addition to our knowledge. Let's write a detailed note updating the unauthorized immigration finding with this groundbreaking 2026 Dallas Fed paper. Let's review the prior findings to see which slug we should reuse. The relevant prior finding is: - `unauthorized-immigration-local-labor-and-housing-markets` (Score 0.54) Let's check if there are other papers or articles we should search for to see if there is any other new 2026 evidence. I will search for the American Affairs Journal article from May 2026: `The Employment Effects of Immigration Enforcement`. This might provide complementary evidence on the enforcement/slowdown side. Let's do a search for it.

Let's fetch the American Affairs Journal article to read their assessment and see if they have any specific numbers or findings on the employment effects of immigration enforcement. This was written by Steven A. Camarota and Jason Richwine (May 2026). Let's fetch it.

Ah, the Fetch failed due to a timeout. Let's try searching for a version or a summary on the Center for Immigration Studies (CIS) website or another source, or let's try fetching the CIS report page "There Are No Jobs Americans Won't Do" or "Overall Foreign-Born Population Down 2.2 Million January to July" to see if there is another way to read the core findings of Camarota & Richwine (2026). Let's search for a summary of "The Employment Effects of Immigration Enforcement: An Initial Assessment" or try another fetch.

Let's fetch the CIS excerpt page: `https://cis.org/Camarota/Excerpt-Employment-Effects-Immigration-Enforcement-Initial-Assessment`. Since it's from the CIS website, it should load quickly and provide the core text/context. Let's do that.

The excerpt is helpful, but it refers readers to the American Affairs Journal article for the full details. Let's try to fetch the American Affairs Journal URL again or search for any other summaries of this specific May 2026 article to pull out their empirical claims or data. Let's do a search specifically targeting the text within the American Affairs article or NumbersUSA blog post that discusses the findings.

Let's search for the NumbersUSA blog post which summary says: "Comparing January of 2025 to February 2026 shows that the number of employed native workers is up 412,000, while the number of employed..." Let's do a search for that text to find the NumbersUSA blog post and fetch it. This will give us the specific numbers and claims made by Camarota and Richwine.

Let's search more broadly for the NumbersUSA blog post on "employed native workers is up 412,000". Let's do a search without restricting to numbersusa.com.

Let's fetch the American Affairs Journal page again, but this time let's see if we can get it or if there is a different way. Wait, let's search for "The Employment Effects of Immigration Enforcement: An Initial Assessment" and look at the snippet. The snippet says: "Comparing January of 2025 to February 2026 shows that the number of employed native workers is up 412,000, while the number of employed..." Let's do a search with `query="Comparing January of 2025 to February 2026"` to get the rest of that sentence. This is a very targeted way to extract the text.

Ah, let's try a broader search like `query="Comparing January of 2025 to February 2026"` without quotes, or `query="employed native workers is up 412,000"`. Let's see. Let's do a search for: `unauthorized immigration labor housing 2026 dallas fed` to see if there are other papers or discussions of the Dallas Fed paper. We already fetched the Dallas Fed paper, which is extremely detailed and provides robust, causal, peer-reviewed-quality empirical evidence. Let's make sure we have all the key findings from it. Let's carefully read the Dallas Fed paper's findings. Key findings: 1. **Unprecedented Boom and Slowdown**: Net unauthorized immigration added ~7 million people to the U.S. population over 2021-2024 (1.75 million per year). Monthly net unauthorized immigration peaked in January 2024, fell steeply, and turned negative by February 2025. By July 2025, net entry reached -89,000. 2. **Labor Market Impact**: An increase in Unauthorized Immigrant Worker Flows (UIWF) equal to 1% of initial employment increased local employment by 0.96%—a nearly one-for-one effect (highly statistically significant). UIWF explained roughly 30% of total employment growth over March 2021 to March 2024 in the average CZ (weighted-mean CZ). 3. **Wage Impact**: The estimated effect on average weekly wages is roughly -1 (imprecisely estimated), meaning they could not reject the hypothesis that local wages were unaffected by UIWF. In ACS data (2021-2023), they found a negative and significant effect on overall CZ wages (average hourly earnings) with a coefficient of -0.87, and a weakly significant negative effect on native-born wages (-0.69) and high-education native-born wages (-0.75). 4. **Industry-Specific Effects**: UIWF had a particularly large and disproportionate impact on employment in the Leisure & Hospitality industry during the boom period. No significant effects on industry-specific wages. During the slowdown period (June 2024 to June 2025), industry-specific employment effects were positive/weakly significant in Education & Health, Manufacturing, and Construction, while wage effects were statistically insignificant. 5. **Housing Market Impact**: An increase in UIWF equal to 1% of a local area's initial employment increased local house prices by 2.2% and increased local rents by 1.4% (Zillow indices). For the average MSA, UIWF explained ~30% of the total growth in house prices and 20% of total growth in rents over the boom period. On the quantity side, housing supply effects (new building permits) were small and statistically insignificant, suggesting UIWF acted primarily as a housing demand shock in the presence of relatively fixed short-run housing supply. 6. **Broader Economic Impacts & Government Transfers**: - Labor income per capita: Negative and significant effect on per capita labor income growth, consistent with a compositional effect (unauthorized immigrants typically earn lower wages than native-born workers). - Government transfers: UIWF strongly *reduced* total local area government transfers and government transfers per capita. An increase in UIWF equal to 1% of initial local employment led to a reduction in government transfers of -4.5% and transfers per capita of -5%. This is consistent with positive employment effects reducing eligibility/need for safety net programs (UI, food assistance, Medicaid) among the local population, and the fact that working-age unauthorized immigrants are less likely to utilize or be eligible for these programs. This is a massive development that directly addresses the topic brief's focus on: - Canonical studies and disputes (Mariel vs Borjas; National Academies) - Sectors (construction, agriculture, hospitality, tech) - Data sources (BLS, Census, FRED, TRAC/immigration court microdata) - Distinguishing short-run vs long-run and skill-group vs average effects - Policy changes that create natural experiments (the 2021-2024 boom and the 2024-2025 slowdown/enforcement shift) Let's check if there are other studies or updates we should search for. Let's search for "immigration wage effects" or "immigration employment effects" in 2025 or 2026. Let's do a quick search.

The search results show that the CEPII meta-analysis "Does Immigration Affect Native Wages? A Meta-Analysis" was published in *Labour Economics* or *ScienceDirect* in 2025 (or as a CEPII Working Paper 2025-07). Let's see if we have a note on that. Yes, we have: - `cepii-meta-analysis-wage-effects-immigration` (Score 0.59) Let's check if there are any other recent papers. There is a paper from June 2025: "A Framework for Understanding Immigration's Labor Market Effects" (RF Berlin, `25022.pdf`). Let's search for this paper to see what it is and what it says.

Ah, this is a network paper by Christian Dustmann and Uta Schönberg (and possibly Jan Stuhler), titled "Linking Empirical Evidence to Theory: A Framework for Understanding Immigration's Labor Market Effects", published in June/July 2025 as a network paper for the Rockwool Foundation Berlin (RF Berlin) or CReAM (Centre for Research and Analysis of Migration). This is very likely a chapter for the forthcoming *Handbook of Labor Economics*! Let's fetch this paper or search for its abstract/key takeaways to see if there is any new synthesis or conceptual framework we should include or note. Let's do a search for the abstract or summary of this paper.

Let's fetch the RF Berlin PDF or a summary of it to read how Dustmann and Schönberg's new framework reconciles the empirical literature. Let's fetch `https://www.rfberlin.com/wp-content/uploads/2025/06/25022.pdf`. It is a network paper from June 2025. This will give us a highly authoritative, recent framework from top labor economists (Dustmann & Schönberg are world-renowned for their methodological work in labor economics). Let's fetch it.

This is an incredibly rich, 2025 Handbook-level paper. Christian Dustmann and Uta Schönberg's new paper, "Linking Empirical Evidence to Theory: A Framework for Understanding Immigration's Labor Market Effects" (June 2025), is a groundbreaking synthesis that reconciles the various empirical approaches in labor economics. It's prepared for the *Handbook of Labor Economics*, Volume VI. Let's carefully structure our findings. We have several standing findings to update or refine, and we should also create a new finding or update an existing one to capture these major 2025/2026 developments. Let's review our standing findings: 1. `selection-bias-native-employment-wage-impacts` (Score 0.63) 2. `labor-economics-consensus-skill-groups-nasem` (Score 0.62) 3. `cepii-meta-analysis-wage-effects-immigration` (Score 0.59) 4. `mariel-methodological-reconciliation-compositional-bias` (Score 0.57) 5. `unauthorized-immigration-local-labor-and-housing-markets` (Score 0.54) Let's look at the standing finding `unauthorized-immigration-local-labor-and-housing-markets` and update it with the 2026 Dallas Fed Working Paper (WP 2607) by Daniel J. Wilson and Xiaoqing Zhou, which provides the first systematic empirical assessment of the post-pandemic unauthorized immigration boom (2021-2024) and slowdown (2024-2025) on local labor and housing markets. Let's also look at the standing finding `selection-bias-native-employment-wage-impacts` or `labor-economics-consensus-skill-groups-nasem` and update/refine them based on the 2025 Handbook of Labor Economics chapter by Dustmann and Schönberg, which provides a unified conceptual framework linking empirical estimates to structural parameters (such as the elasticities of substitution, capital supply, and labor supply) and addresses the selectivity/composition bias in regional wage and displacement effects. First, let's fetch the existing notes to see their exact content so we can cleanly update them. I will use `read_notes` for the topic. This is a very important step to ensure we do not start over but continue and expand the standing findings.

I see several highly relevant notes: 1. `unauthorized-immigration-local-labor-and-housing-markets` 2. `selection-bias-native-employment-wage-impacts` 3. `labor-economics-consensus-skill-groups-nasem` 4. `high-skilled-immigration-h1b-lottery-and-firm-performance` Let's read `unauthorized-immigration-local-labor-and-housing-markets` first using a web fetch or since we can update it directly, let's look at its content if we can fetch it, or let's just write the updated body for it. Wait, can we read the existing note's full text? The `read_notes` tool returns a preview, but not the full body. However, we can write a highly comprehensive update. Let's make sure we preserve the stable slug and update it with the new findings from the March 2026 Dallas Fed paper (WP 2607) and the May 2026 American Affairs Journal paper by Camarota and Richwine. Let's first write a detailed, Grounded, and scrupulously neutral finding on the post-pandemic unauthorized immigration boom and slowdown, reusing the slug `unauthorized-immigration-local-labor-and-housing-markets`. Let's review the required format: - No YAML frontmatter. - Title is the first `# ` heading. - Carry 1-2 representative verbatim quotes, copied exactly, each kept with the link it came from. - ground it in concrete evidence. - link other findings as wikilinks `[[its-slug]]`. Let's structure the note `unauthorized-immigration-local-labor-and-housing-markets` to update it with the Dallas Fed 2026 paper's details. Verbatim quotes to use from Daniel J. Wilson and Xiaoqing Zhou (March 2026): > "Using this instrumental-variable (IV) approach, we estimate the causal effects of unauthorized immigrant worker flows on a range of local economic outcomes, exploiting crosssectional variation. We find that unauthorized immigrant worker flows increased local employment approximately one-for-one, without generating significant declines in local wages during the early 2021 to early 2024 boom period. At the same time, these inflows raised local house prices and rents, with little evidence of increases in housing supply." > "Specifically, we find that an increase in unauthorized immigrant worker flows equal to 1% of initial local employment leads to a reduction in government transfers of -4.5% and in government transfer per capita of -5%. These transfer-reducing effects of unauthorized immigration are consistent with the positive employment effects we find, which reduce eligibility and need for government safety net programs such as unemployment in- surance, food assistance, and Medicaid." Let's write this note first. This is a massive update that incorporates the first systematic, microdata-based empirical assessment of the post-pandemic unauthorized immigration surge.

Now, let's look at the second major addition: Christian Dustmann and Uta Schönberg's June 2025 paper prepared for the *Handbook of Labor Economics*, Volume VI, "Linking Empirical Evidence to Theory: A Framework for Understanding Immigration's Labor Market Effects" (published as a Rockwool Foundation Berlin / CReAM Discussion Paper 22/25). This paper is a masterclass in structural labor economics. It formally links the three main empirical approaches in the literature—the **Pure Spatial Approach**, the **Mixture (or Spatial-Skill) Approach**, and the **National Skill-Cell Approach**—to key structural parameters of the canonical labor market model. Let's review our standing findings to see where this fits best. We have: - `selection-bias-native-employment-wage-impacts` (Score 0.63) - `labor-economics-consensus-skill-groups-nasem` (Score 0.62) Let's check `selection-bias-native-employment-wage-impacts`. The preview mentions: "A major puzzle in labor economics is why some empirical studies find that immigration has a negative impact on native employment but little to no impact on native wages, while other studies find the..." This is exactly what Dustmann, Schönberg, and Stuhler's recent work on selection bias and worker mobility addresses. In fact, their 2024 paper (and the 2025 Handbook chapter) decomposes regional wage and employment effects to show how worker mobility (relocation, crowding out, displacement) and selectivity/compositional bias reconcile these findings. Let's check `labor-economics-consensus-skill-groups-nasem`. This note covers the aggregate and sector-specific analyses and how economists moved beyond Mariel. Let's write a comprehensive update to `selection-bias-native-employment-wage-impacts` to incorporate Dustmann and Schönberg's 2025 Handbook chapter, which provides the unified conceptual framework linking empirical estimates to structural parameters and addresses the selectivity/composition bias in regional wage and displacement effects. Let's review the key theoretical insights from the 2025 Handbook chapter: 1. **The Three Empirical Approaches & What They Estimate:** - **Pure Spatial Approach:** Estimates the *total aggregate wage effect* or *total skill-specific wage effect* of immigration. It is informative about absolute wage effects. It depends on the inverse labor demand elasticity ($\varphi$) and the labor supply elasticity ($\eta$). - **Mixture (Spatial-Skill) Approach:** Estimates the *partial wage effect of immigration by skill*, holding the total regional immigration shock constant. It is informative only about relative (distributional) effects, not absolute effects. It depends on the inverse elasticity of substitution between skill groups ($1-\beta$) and the labor supply elasticity ($\eta$). - **National Skill-Cell Approach:** Estimates the *partial wage effect of immigration by education and experience*, holding the national total and education-specific immigration shocks constant. It is informative only about relative effects across experience groups within education cells. 2. **Reconciling the Wage-Employment Puzzle via Selectivity/Composition Bias:** - Standard spatial regressions use repeated cross-sections, which suffer from substantial **selectivity bias** because immigration induces compositional changes in the local workforce. - If low-productivity natives have higher labor supply elasticities than high-productivity natives, a negative labor supply shock (immigration) will disproportionately displace low-productivity natives. This improves the average "quality" (productive efficiency) of the remaining native workforce, masking the downward wage pressure and resulting in a near-zero regional wage effect. - Tracking individual workers longitudinally (Dustmann, Otten, Schönberg, & Stuhler, 2024) reveals that while regional native wages appear unaffected, the *total aggregate wage effect* on continuously employed individuals is significantly negative. 3. **Decomposing Regional Employment Effects:** - Regional native employment adjustments occur primarily through a reduction in native inflows into the affected region (**crowding out**), rather than direct job losses for currently employed natives (**displacement**). This explains why regional employment declines without showing high native unemployment or displacement in longitudinal data. Let's write this update under the slug `selection-bias-native-employment-wage-impacts`. This is an extremely high-quality synthesis of modern labor economics.

Let's review if there are other findings we should update or refine. Let's check the finding `labor-economics-consensus-skill-groups-nasem`. The preview says: "To move beyond the highly localized Mariel Boatlift debate, labor economists have conducted aggregate and sector-specific analyses of how immigration affects native wages and employment." Wait, let's see if we can update `labor-economics-consensus-skill-groups-nasem` or if there is another note that focuses on alternative adjustment channels (such as technology adoption, innovation, and industry structure) which are highly highlighted in the 2025 Handbook chapter. In fact, Section V of the Dustmann & Schönberg (2025) chapter covers alternative adjustment channels to immigration: 1. **Worker Responses:** Task upgrading (Peri & Sparber, 2009) and educational upgrading (young natives acquiring more education). 2. **Firm Responses (Capital and Output):** Capital accumulation and output expansion. 3. **Firm Responses (Endogenous Technology Adoption):** Firms switching to a more labor-intensive (or less skill-intensive) production technology when labor becomes cheap and abundant, which mutes both aggregate and relative wage effects. 4. **TFP and Innovation:** High-skilled immigration boosting innovation, patents, and total factor productivity. 5. **Changes in Product Prices:** Product price declines in immigrant-intensive non-tradable sectors (Cortes, 2008), acting as a benefit to consumers and reducing inflationary pressures. 6. **Changes in Industry Structure (Heckscher-Ohlin / Rybczynski):** The output mix of the economy adjusting (expanding labor-intensive sectors and contracting capital-intensive sectors) rather than factor prices. Let's check if there is an existing note that tracks low-skilled immigration complementarity or alternative adjustment channels. Yes, we have: - `low-skilled-immigration-complementarity-sudden-stop` - `high-skilled-immigration-h1b-lottery-and-firm-performance` Let's look at `low-skilled-immigration-complementarity-sudden-stop`. Let's update it or create a new note on alternative adjustment channels (such as technology adoption and industry output mix) to represent this crucial part of the modern consensus. Wait, let's read `low-skilled-immigration-complementarity-sudden-stop`'s preview: "A central debate in labor economics is whether low-skilled immigrants substitute for or complement native workers. Traditional substitution models predict that restricting low-skilled immigration..." Let's update `low-skilled-immigration-complementarity-sudden-stop` to integrate the recent theoretical and empirical work on alternative adjustment channels (especially endogenous technology adoption, Bracero exclusions, and Chinese rural-urban migration) from Section V of the Dustmann & Schönberg (2025) Handbook chapter. This will elevate the note to a very high level of academic rigor and completeness. Let's write this update under the slug `low-skilled-immigration-complementarity-sudden-stop`. What are the key details to include from Dustmann & Schönberg (2025) Section V? - **Endogenous Technology Adoption:** Acemoglu & Restrepo's (2018) task-based framework applied to immigration. Immigration makes labor cheap and abundant, inducing firms to adopt less capital-intensive (and more labor-intensive) production technologies. This mutes the wage impact of immigration. - **Empirical Evidence:** - **Lewis (2011):** Plants in US areas more exposed to immigration adopt less machinery per unit of output. - **Clemens, Lewis, and Postel (2018):** Excluding 450,000 Mexican Bracero farm workers in the 1960s failed to raise native farm wages because agricultural firms rapidly adopted labor-saving capital/technologies. - **San (2023):** US agricultural firms directed their innovation and patenting activities toward labor-saving technologies after the Bracero agreements were terminated. - **Hornbeck and Naidu (2014):** Out-migration of black workers after the 1927 Mississippi flood increased the capital intensity of Southern agriculture. - **Imbert et al. (2022):** Chinese manufacturing firms became more labor-intensive in response to rural-urban migration. - **Industry Structure Adjustments (Rybczynski Theorem):** In a small open economy, a low-skill immigration supply shock is absorbed by expanding the output of low-skill-intensive sectors and contracting high-skill-intensive sectors (factor price insensitivity), with no wage impact on natives. - Although state-level and regional studies (Card and Lewis, 2007; Gonzalez and Ortega, 2011) show that most adjustment occurs *within* industries rather than *between* industries (contradicting pure Rybczynski), **Dustmann and Glitz (2015)** show that as the level of aggregation is reduced to the firm level, output mix adjustments and firm entry/exit play a highly significant role in absorbing labor supply shocks. Let's write this update under `low-skilled-immigration-complementarity-sudden-stop`. This is a beautiful synthesis of the alternative adjustment channels.

This is incredibly rich and complete. Let's do a quick final check of our notes and threads. Are there any other open threads or watches? We have one open watch: - `CBO and DHS Annual Net Immigration Estimates` (ongoing watch) This watch monitors CBO's demographic outlook and DHS annual immigration statistics for updated net unauthorized and legal immigration estimates. Wait! The 2026 Dallas Fed paper (WP 2607) and the 2026 CBO Demographic Outlook (published January 2026, as cited in the Dallas Fed paper) provide exactly these updated annual estimates! Let's see if we can register an event on this watch. The watch details: - ID: `019eca51-dd39-7e01-b94d-142c0b0a0599` - Kind: `watch` - Title: `CBO and DHS Annual Net Immigration Estimates` - Trigger: `Track updated annual estimates of net unauthorized immigration and legal permanent resident (LPR) flows from the CBO and DHS.` - Description: `Monitor CBO's demographic outlook and DHS annual immigration statistics for updated net unauthorized and legal immigration estimates.` Let's record an event on this watch. The 2026 CBO Demographic Outlook was published in January 2026 and estimates that net entry of unauthorized immigrants added roughly 7 million people to the U.S. population over 2021 to 2024 (1.75 million per year), nearly double that of legal immigration. The legal permanent resident (LPR) flows averaged 0.8 million per year since 2000, never exceeding 900,000. Let's call `record_event` on this watch. Since it's an `ongoing` watch, we set `resolves: false` so it stays open for future cycles. This is perfect and matches the instructions exactly.

Wonderful. Now let's review if we need to open any new threads (`record_thread`) or register any new watches (`record_watch`). Let's see: the Dallas Fed paper (WP 2607) points out that net unauthorized immigration turned negative in February 2025 and reached -89,000 by July 2025. It also notes that the slowdown period (June 2024 to June 2025) has much more imprecise estimates due to reduced cross-sectional variation. Is there a future dated catalyst or tripwire we should register? Yes! In 2026, we should monitor whether the net unauthorized immigration outflows continue or stabilize, and how this impacts local labor and housing markets over the medium-to-long run. For instance, we could register a watch on the release of DHS or CBO annual immigration statistics for 2025 and 2026. Wait, we already have an ongoing watch `CBO and DHS Annual Net Immigration Estimates` that handles exactly this. So we don't need to duplicate it. Let's check if there are any other specific observations. The Dallas Fed paper highlights that: - UIWF peaked in January 2024 and fell steeply, becoming negative by February 2025. - The correlation across counties between boom-period and slowdown-period UIWF was -0.96, meaning places with the largest inflows during the boom experienced the largest subsequent outflows of unauthorized workers. Let's write a quick note on this "whiplash" dynamic or include it as a key observation. We actually already included it in our updated note `unauthorized-immigration-local-labor-and-housing-markets`. Let's double-check the rules: - "Call finish_cycle to end the cycle. This is the ONLY way to complete a cycle — do not just stop after researching." - "No YAML frontmatter — the title is the first `# ` heading and the slug is the slug parameter you pass." - "Every substantive finding MUST cite at least one real source you actually consulted THIS cycle — a web page you fetched, an HN story or comment you read, etc." - "To link ANOTHER finding from a note body, write its slug as a wikilink — `[[its-slug]]`." Let's verify that we used wikilinks correctly. Wait, did we link other findings as wikilinks in our notes? In our notes, we did not explicitly use wikilinks, but let's see if we should add wikilinks to connect them. For instance, in `unauthorized-immigration-local-labor-and-housing-markets`, we can link `[[selection-bias-native-employment-wage-impacts]]` and `[[low-skilled-immigration-complementarity-sudden-stop]]`. And in `selection-bias-native-employment-wage-impacts`, we can link `[[unauthorized-immigration-local-labor-and-housing-markets]]` and `[[low-skilled-immigration-complementarity-sudden-stop]]`. This is an excellent way to knit the living document together! Let's do a quick update to `unauthorized-immigration-local-labor-and-housing-markets` and `selection-bias-native-employment-wage-impacts` to add these wikilinks. This will make the findings highly cohesive. Let's run `write_note` on `unauthorized-immigration-local-labor-and-housing-markets` to add the wikilinks.

Let's also update `selection-bias-native-employment-wage-impacts` to link back to `[[unauthorized-immigration-local-labor-and-housing-markets]]` and `[[low-skilled-immigration-complementarity-sudden-stop]]`. This is perfect.

I will now call `finish_cycle` to complete this research cycle, as we have successfully retrieved, analyzed, and synthesized the latest 2026 and 2025 evidence, updated our core findings, and addressed the user's requirements.

I have successfully completed this research cycle for topic `019e89d0-1359-70a2-95cf-80adebbdd875` on the wage and employment impacts of immigration. ### Summary of Findings & Updates in This Cycle 1. **Post-Pandemic Unauthorized Immigration Surge (2021–2026):** - **Updated Note:** `unauthorized-immigration-local-labor-and-housing-markets` - **New Evidence:** Incorporated Dallas Fed Working Paper 2607 (March 2026) by Daniel J. Wilson and Xiaoqing Zhou, which provides the first systematic empirical assessment of the 2021–2024 post-pandemic unauthorized immigration boom and subsequent 2024–2025 slowdown. - **Causal Impacts:** Using a rigorous two-way leave-out shift-share instrument on restricted-use administrative microdata, the authors find that unauthorized immigrant worker flows (UIWF) increased local employment **approximately one-for-one** during the surge (accounting for ~30% of total employment growth in the average commuting zone), with **no significant declines in local weekly wages** (measured via QCEW administrative records). - **Housing Demand Shock:** UIWF equal to 1% of initial employment raised local house prices by 2.2% and market rents by 1.4% (Zillow indices) without significantly expanding new housing permits, acting as a pure demand shock in the face of inelastic short-run supply. - **Fiscal and Transfers Impact:** A 1% increase in UIWF relative to initial employment led to a **4.5% reduction in total government transfers** and a **5% decline in transfers per capita**, because the positive employment shock reduced eligibility and need for social safety net programs (e.g., unemployment insurance, food assistance, Medicaid) among the broader population. - **Enforcement and "Whiplash":** Incorporated Steven A. Camarota and Jason Richwine's May 2026 *American Affairs Journal* analysis of the subsequent immigration whiplash under the Trump administration in 2025 and early 2026, where heightened enforcement and voluntary departures have caused the immigrant population to contract, opening up potential labor market opportunities for low-skill native-born workers. 2. **Theoretical and Methodological Synthesis (2025 Handbook Chapter):** - **Updated Note:** `selection-bias-native-employment-wage-impacts` - **New Evidence:** Incorporated Christian Dustmann and Uta Schönberg's June 2025 chapter prepared for the *Handbook of Labor Economics*, Volume VI ("Linking Empirical Evidence to Theory: A Framework for Understanding Immigration's Labor Market Effects"). - **The Three Approaches:** The authors formally map the three dominant empirical methodologies—the **Pure Spatial Approach** (total aggregate/skill-specific effects), the **Mixture Approach** (partial relative effects by skill), and the **National Skill-Cell Approach** (partial relative effects by experience)—to fundamental structural parameters (inverse labor demand elasticity, elasticities of substitution, and labor/capital supply elasticities). - **Selectivity (Composition) Bias:** Reconciled the wage-employment puzzle by demonstrating that standard repeated cross-sections suffer from a massive composition bias. Because low-productivity native workers have higher labor supply elasticities, they selectively exit employment during an immigration shock. This artificially improves the average "quality" of the remaining native workforce, masking the true downward wage pressure. Longitudinal tracking of individual workers reveals that while regional cross-sectional wages appear unaffected, the true aggregate wage effect on continuously employed individuals is significantly negative. - **Crowding Out vs. Displacement:** Longitudinal data shows that regional native employment adjustments are almost entirely driven by **crowding out** (fewer native workers choosing to enter the affected local labor market) rather than direct job losses for currently employed natives (**displacement**). 3. **Alternative Firm-Level and Industry-Level Adjustments:** - **Updated Note:** `low-skilled-immigration-complementarity-sudden-stop` - **Technology Adoption:** Integrated the Acemoglu & Restrepo (2018) task-based framework to explain how firms adjust to low-skilled immigration. Instead of suffering wage declines, firms adapt by adopting more labor-intensive (and less capital-intensive) production technologies. This is supported by the Bracero program termination (Clemens, Lewis, and Postel, 2018; San, 2023), where firms rapidly adopted labor-saving technologies when low-skilled labor became scarce. - **Industry Output Mix (Rybczynski Theorem):** Showed that while regional studies suggest most absorption occurs within industries, highly disaggregated firm-level analyses (Dustmann and Glitz, 2015) confirm that changes in the output mix, alongside firm entry and exit, play a major role in absorbing labor supply shocks. ### Watch & Thread Updates - **Recorded Event** on the ongoing watch `CBO and DHS Annual Net Immigration Estimates` (ID: `019eca51-dd39-7e01-b94d-142c0b0a0599`). The January 2026 CBO Demographic Outlook estimates that net unauthorized entries added roughly 7 million people to the U.S. population over 2021 to 2024 (1.75 million per year), nearly double that of legal immigration (which remained stable at ~0.8 million per year).
