Workforce Reorganization

Research on how firms reorganize work in response to technology, trade, changing skills, geography, and new business models. Coverage includes automation, occupational change, team design, outsourcing, remote work, and shifts between industries.

AI Summary. The authors find AI-native U.S. startups are 25% smaller than non-AI startups in the same industry and cohort, with 13% higher engineer shares, roughly 15% lower shares of entry-level workers and managers, flatter hierarchies, and comparable valuations. They argue embedding AI into products lets firms scale knowledge work without large teams.

“AI native” firms – firms organized around AI founded btw 2020 and 2024 – had headcounts ~25% lower than their industry peers. These firms’ share of engineers is ~13% higher, while their share of entry-level workers and managers is ~15% lower.

How do AI-native startups differ from other startups in workforce structure?

Core argument: AI-native startups are 25% smaller than non-AI startups in the same industry-cohort, yet their valuations are comparable, which the authors say suggests higher value created per employee.

Drawing on Y Combinator batches W20–F24 and U.S. venture-backed startups whose first financing closed between 2020 and 2024, we classify each firm’s AI-native status and link it to workforce microdata on team size, function, seniority, and hierarchy. Relative to non-AI startups in the same industry-cohort, AI-native firms are 25% smaller. Their share of engineers is 13% greater, and the shares of entry-level workers and managers are each roughly 15% lower. Their hierarchies are half a seniority level flatter—yet valuations are comparable, suggesting higher value created per employee. We argue these patterns reflect two channels: a process channel, in which AI changes how people work inside the firm, and a product channel, in which AI capabilities are built into what the firm sells. Using text from product descriptions and job postings, we find that embedding AI into the product, beyond layering on AI tools into existing workflows, is a primary way startups are scaling “knowledge work” without large teams of knowledge workers.

AI Summary. A survey of firms finds 18% use AI in at least one business function (32% employment-weighted), with adoption concentrated in large firms and knowledge-intensive sectors such as information, professional services, and finance. Scope remains narrow: 57% of adopters use AI in three or fewer functions, 66% use it to augment tasks, and only 2% report employment reductions.

Census data show that 18% of US firms used AI in at least one function (32% employment-weighted). 66% say it augments work; only 2% report job cuts, but the deeper firms embed AI into operations, the more employment falls.

How widely are firms adopting AI, and does it reduce employment?

Core argument: AI use concentrates in large firms and knowledge-intensive sectors, reaching 50%–60% (60%–70% employment-weighted) among very large firms in Information, Professional Services, and Finance.

During Nov 2025–Jan 2026, 18% of firms used AI in at least one function (32%, employment-weighted), with adoption expected to reach 22% within six months. Use is concentrated in large firms and knowledge-intensive sectors, reaching 50%–60% (60%–70%, employment-weighted) among very large firms in Information, Professional Services, and Finance. Among adopters, scope remains limited: 57% use AI in three or fewer functions, most often Sales and Marketing (52%), Strategy (45%), and IT (41%). Worker-level use appears in 23% (41%, employment-weighted) of firms, primarily for writing, document analysis, and information search; 65% restrict use to three or fewer tasks. Evidence suggests both top-down and bottom-up diffusion: worker use can occur without firm adoption, and vice versa. Most firms (66%) use AI for task augmentation, while employment reductions are rare (2%).

AI Summary. The US population is split evenly among urban, suburban, and rural areas, but 64% of those living at suburban densities reside in prosperous or comfortable ZIP codes, versus 36% in rural and 38% in urban ones. County distress scores correlate strongly with life expectancy, with prosperous counties averaging 5.3 years longer.

An analysis of census data finds residents of the mean “prosperous” (top-quintile) county live 5.3 years longer than those in the mean “distressed” (bottom-quintile) one, with the discrepancy between the top and bottom percentiles widening to 8 years.

Do suburban areas concentrate America's prosperity and longer life expectancy?

Core argument: 64% of the U.S. population living at semi-urban (suburban) densities resides in prosperous or comfortable ZIP codes, far above the 36% in rural areas and 38% in urban ones.

Nationally, the country’s population is evenly divided between urban, semi-urban (which we’ll call suburban), and rural areas. Fully 55% of the population in top-tier ZIP codes live at suburban densities, compared to only 20% in the bottom (distressed) tier. Put differently, fully 64% of the U.S. population living at semi-urban densities reside in prosperous or comfortable zip codes (Figure 2). That is far and above the 36% in rural areas or 38% in urban ones. County distress scores are strongly correlated with life expectancy. Residents of the average prosperous county live over five years longer (5.3 years to be exact) than those in the average distressed one, widening to 8 years in the top and bottom percentiles.

AI Summary. Government transfers rose from 8.2% of Americans' total personal income in 1970 to 17.6% in 2022, making them the third largest income source after work and investments. The share of U.S. counties drawing a quarter or more of personal income from transfers rose from under 1% in 1970 to 53% in 2022.

Transfer payments made up 18% of all US personal income in 2022, up from 8% in 1970. Social Security/Medicare made up 56% of the increase from 1970 to 2022, and income maintenance programs/Medicaid accounted for 35%. @kenanfikri @BenGlasner

How much have government transfers grown as a share of personal income?

Core argument: Government transfers rose from 8.2% of Americans' total personal income in 1970 to 17.6% in 2022, ranking third as an income source after work and investments.

Transfers’ share of Americans’ total personal income has more than doubled over the past 50 years, from 8.2% in 1970 to 17.6% in 2022. They are the third largest source of Americans’ personal income, after income from work and investments. The average American received $11,500 in income from government transfers in 2022, compared to $40,500 in income derived from work and $12,900 from investments. Today, most U.S. counties depend on a level of government transfer income that was once reserved only for the most distressed places. In 1970, not even 1% of counties derived a quarter or more of their total personal income from transfers. In 2000, just 10.4% did. But by 2022, 53% of counties were receiving a quarter or more of their income from transfers. Increasing participation (as populations age) and rising underlying costs (driving up the expense of health-related programs, in particular) are the most significant factors at play. Income maintenance programs only account for 11.4% of the real increase in transfers from 1970 to 2022. In stark contrast to the rising elderly share of the population, the poor share has been stable.

AI Summary. The authors find China's tariff cuts after joining the World Trade Organization exceeded the norm of reciprocity, which raised aggregate real incomes in the United States and the rest of the world through better terms of trade while amplifying the China Shock. They estimate this shifted employment from tradable to non-tradable sectors abroad.

.@ChadBown and team find that China’s tariff reductions in its WTO accession exceeded reciprocity norms, increasing real incomes but driving an incremental 4% decline in labor demand for tradable goods in the rest of the world.

Did one-sided tariff cuts raise incomes while amplifying trade shocks?

Core argument: China's tariff reductions after its WTO accession exceeded the norm of reciprocity, under which exchanged tariff cuts leave relative world prices between countries unchanged.

When countries exchange tariff cuts that abide by reciprocity, relative world prices (the terms of trade between them) do not change. We find the tariff reductions China implemented after its WTO accession exceeded the norm of reciprocity. This deviation from reciprocity increased aggregate real incomes in the United States and in the rest of the world through improvements in their terms of trade, but it also amplified the magnitude of the China Shock. Figure 2 presents the percentage change in employment in the tradable sector and in the non-tradable sector in the rest of the world due to the movement in the terms of trade resulting from the actual changes in tariff between China and the rest of the world from 1990-2007. We find that China exceeding reciprocity resulted in employment shifting from the tradable sector to the nontradable sector in the rest of the world.

AI Summary. Administrative tax data show that entrants to the taxi and limousine services industry after online ridesharing platforms appeared were more likely to be young, female, White, and U.S.-born, and to combine driving income with wage and salary jobs. Average net earnings of entrants fell to $2,110, consistent with driving being used to supplement income.

Date Posted:

From 2013-2019, drivers in the taxi/rideshare industry grew six-fold to 1.3mm. The mean entrant in 2016 had net earnings of just $2,110, as the share of drivers supplementing other wage and salary earnings rose from <20% in 2011 to over 70% in 2015.

How did ridesharing platforms change who drives and what they earn?

Core argument: Average net earnings of entrants to the Taxi and Limousine Services industry (NAICS 4853) fell to $2,110 by 2016, while 2011 nonemployer incumbents averaged $12,290 in net earnings (in 2015 dollars), according to administrative tax data.

Using administrative tax data, we explore the effects of the introduction of online ridesharing platforms on entry, employment, and earnings in the Taxi and Limousine Services industry [NAICS 4853]. New entrants were more likely to be young, female, White, and U.S. born, and to combine earnings from ridesharing with wage and salary earnings. The first two panels of Figure 4 display the gross receipts and net earnings of the 2011 NAICS 4853 nonemployer incumbents and of entrants to the industry. Incumbents had net earnings that averaged just $12,290 (in 2015 dollars) in 2011. Beginning in 2013, the net earnings of NAICS 4853 entrants began to fall off sharply. By 2016, the average NAICS 4853 entrant had net earnings of just $2,110. The decline in average nonemployer earnings and increased propensity to combine nonemployer self-employment with a wage and salary job among NAICS 4853 entrants are consistent with earlier findings that many app-based drivers use driving to supplement or smooth their earnings rather than as a primary source of income

AI Summary. Survey data show 6.30% of US workers who switched to remote work after the pandemic moved states, compared with 3.58% of those who kept commuting, and plausibly exogenous changes in employer remote-work policies predict both higher remote work and higher interstate migration. Remote workers staying with the same employer are more likely to move states.

The rise in the work-from-home share accounts for more than half of the rise in overall interstate migration since 2019, and states with greater WFH opportunities experienced more out-migration.

Does remote work increase interstate migration?

Core argument: In the Real-Time Population Survey, 6.30% of workers who switched to work from home after Covid moved states since February 2020, compared with 3.58% of workers who commuted both before and after Covid.

In the American Community Survey (ACS), annual interstate migration [AIM] among adults ages 18-64 fell from 2.75% in 2005 to 2.23% in 2010. AIM rose from 2.40% in 2019 to 2.66% in 2022. Data from the Real-Time Population Survey (RPS) provide micro evidence that access to WFH increases interstate migration. [Fig. 4 shows] that 6.30% of workers who switched to WFH post-Covid moved states since February 2020, [compared to] 3.58% of workers who commuted both pre- and post-Covid. A potential concern [is]that the pandemic increased the desire to move across states and a large share of these moves involve WFH, but WFH itself was not necessary for those moves to happen [and thus not causal]. Using novel questions in the RPS - whether workers who commuted prior to the pandemic did so due to job characteristics, personal preferences, or employer requirements, and whether employer WFH policies had changed since 2020 - we find that plausibly exogenous changes in employer WFH policies predict higher rates of WFH and higher rates of interstate migration. Finally, consistent with the interpretation that WFH reduces the benefit of living near a workplace, we find that (i) among workers who remain with their pre-pandemic employer, WFH workers are more likely to move states, and (ii) among workers who move states WFH workers are less likely to change employers.

  3. Plausibly exogenous changes in employer work-from-home policies predict higher rates of work from home and higher rates of interstate migration; among workers staying with pre-pandemic employers, those working from home are more likely to move states.

AI Summary. Cultural individualism accounts for about one-third of cross-country differences in working from home, with the shift from the lowest-individualism country (Taiwan) to the highest (the US) associated with 0.7 more fully paid work-from-home days per week, and 1.1 more among college graduates. The authors find individualism explains more of this variation than industry mix, population density, or lockdown stringency.

A measure of individualism accounts for about 1/3 of the cross-country variation in work-from-home rates, with WFH most prevalent in the Anglosphere and least in Asia. @PabloZarate98 @I_Am_NickBloom @Jose_MariaRD @cevatgirayaksoy

Does culture explain why working from home varies across countries?

Core argument: Cultural factors, specifically Individualism, account for about one-third of cross-country differences in work from home, with the move from Taiwan's lowest Individualism score to the highest in the US associated with 0.7 more full paid WFH days per week.

We examine how work from home varies across countries and across US workers. Our key finding is that cultural factors – specifically Individualism – account for about one-third of the differences across countries. Figure 3 shows the bivariate relationship between individualism and WFH. Moving from the country with the lowest Individualism score (Taiwan) to the one with the highest (the US) is associated with 0.7 more full paid WFH days per week (1.1 among college graduates). Individualism explains far more of the variation than industrial composition, population-weighted density, or lockdown stringency. Across US workers, industry and population density are the two most important determinants. But cultural factors are still statistically significant. Respondents who reside in counties that voted for Joe Biden in 2020 by a larger margin WFH at higher rates even after accounting for industry, state-level wages, population density, and a battery of demographics.
