Hours Worked and Lifetime Earnings Inequality
We document large differences in lifetime hours of work using data from the NLSY79 and argue that these differences are an important source of inequality in lifetime earnings. To establish this we develop and calibrate a rich heterogeneous agent model of labor supply and human capital accumulation that allows for heterogeneity in preferences for work, initial human capital and learning ability, as well as idiosyncratic shocks to human capital throughout the life-cycle. Our calibrated model implies that almost 20 percent of the variance in lifetime earnings is accounted for by differences in ...

Mind the Gap: AI Adoption in Europe and the US
This paper combines international evidence from worker and firm surveys conducted in 2025 and 2026 to document large gaps in AI adoption, both between the US and Europe and across European countries. Cross-country differences in worker demographics and firm composition account for an important share of these gaps. AI adoption, within and across countries, is also closely linked to firm personnel management practices and whether firms actively encourage AI use by workers. Micro-level evidence suggests that AI generates meaningful time savings for many workers. At the macro level, in recent ...

The Rapid Adoption of Generative AI
Generative artificial intelligence (AI) is a potentially important new technology, but its impact on the economy depends on the speed and intensity of adoption. This paper reports results from a series of nationally representative U.S. surveys of generative AI use at work and at home. As of late 2024, nearly 40 percent of the U.S. population age 18-64 uses generative AI. 23 percent of employed respondents had used generative AI for work at least once in the previous week, and 9 percent used it every work day. Relative to each technology’s first mass-market product launch, work adoption of ...
Real-Time Survey to Provide Timelier Labor Market Data in Era of COVID-19
An effective economic policy response to the rapidly evolving coronavirus (COVID-19) crisis requires timely and accurate information on its impact. To help reduce the information gap, we introduce the Real-Time Population Survey.
The Recent Surge in Immigration and Its Impact on Measured Productivity Growth
The number of recent immigrants to the U.S. varies greatly among data sources. What might an undercount of this population mean for U.S. productivity growth?
What’s Behind the Sharp Drop in Labor Force Participation?
In the first half of 2026, the falling labor force participation rate was mostly due to a statistical correction and an aging population. But a sharp drop in prime-age workers also occurred.
Real-Time Population Survey Suggests U.S. Job Losses Slowed in Early May
Survey results for the week of May 10 suggest further declines in employment and an increase in unemployment relative to the week of April 26 – May 2, though both changes are within the survey’s margin of error.
Breakeven Employment Growth: Estimate Range Widens in 2026
Volatile immigration projections create uncertainty in the 2026 breakeven employment growth estimate, which now ranges from 15,000 to 87,000 jobs per month.
What Is Affecting the CPS Data on Shifts in Immigrant and Native-Born Populations?
This analysis suggests that CPS estimates of a sharp drop in the U.S. immigrant population and a surge in the native-born population in 2025 are overstated because of survey limitations.

Measuring Trends in Work From Home: Evidence from Six U.S. Datasets
This paper documents the prevalence of work from home (WFH) in six U.S. data sets. These surveys measure WFH using different questions, reference periods, samples, and survey collection methods. Once we construct samples and WFH measures that are comparable across surveys, all surveys broadly agree about the trajectory of aggregate WFH since the Covid-19 outbreak. The most important source of disagreement in the level of WFH across surveys is in WFH by self-employed workers; by contrast, surveys closely agree on rates of WFH among employees. All surveys agree that in 2024 WFH remains ...
