Working Paper
Minimum Wage Increases and Vacancies
We estimate the impact of minimum-wage increases on the quantity of labor demanded as measured by firms’ vacancy postings. We use propriety, county-level vacancy data from the Conference Board’s Help Wanted Online database. Our identification relies on the disproportionate effects of minimum-wage hikes on different occupations, as the wage distribution around the binding minimum wage differs by occupation. We find that minimum-wage increases during the 2005-2018 period have led to substantial declines in vacancy postings in at-risk occupations, occupations with a larger share of ...

A New Estimate of the Natural Rate of Unemployment
The author presented a new estimate of the natural (or trend) rate of unemployment that accounts for changes in the age, sex, and skill composition of the labor force. Based on this new estimate, the natural rate of unemployment has declined by 0.4 percentage point since 1994 and is currently 4.6 percent. Ongoing demographic and technological changes could lower the trend rate further to 4.4 percent by the end of 2022.

Health-care reform or labor market reform? a quantitative analysis of the Affordable Care Act
An equilibrium model with ?rm and worker heterogeneity is constructed to analyze labor market and welfare implications of the Patient Protection and Affordable Care Act (ACA). Our model implies a signi?cant reduction in the uninsured rate from 22.6 percent to 5.6 percent. {{p}} The model predicts a moderate positive welfare gain from the ACA, due to redistribution of income through Health Insurance Subsidies at the Exchange as well as Medicaid expansion. About 2.1 million more part-time jobs are created under the ACA, in expense of 1.6 million full-time jobs, mainly because the link between ...

Minimum Wage Increases and Vacancies
Using a unique data set and a novel identification strategy, we estimate the effect of minimum wage increases on job vacancy postings. Utilizing occupation-specific county-level vacancy data from the Conference Board’s Help Wanted Online for 2005-2018, we find that state-level minimum wage increases lead to substantial declines in existing and new vacancy postings in occupations with a larger share of workers who earn close to the prevailing minimum wage. We estimate that a 10 percent increase in the state-level effective minimum wage reduces vacancies by 2.4 percent in the same quarter, ...

Labor market dynamics with endogenous labor force participation and on-the-job search
Empirical evidence shows that worker flows in the U.S. labor market are very large. Previous studies have mainly focused on documenting and modeling worker flows between employment and unemployment only. However, these studies ignore other important labor flows including movements in and out of the labor force, and worker flows from one job directly to another job. Improving our understanding of this broader set of labor market flows is critical for assessing the merits of labor market policies such as unemployment insurance and minimum wage. ; This paper focuses on the broader set of worker ...

Disappearing Routine Occupations and Declining Prime-Age Labor Force Participation
I study the effect of disappearing routine occupations on the decline in the labor force participation rate of prime-age individuals since the 1990s. I use multiple data sources and empirical models to study this relationship. First, I exploit state-level variation and show that the long-term trends of declining routine employment and prime-age labor force participation are highly correlated. Second, I narrow the geographic unit to local labor markets and quantify the causal effect of declining routine employment on the labor market outcomes of prime-age individuals. My results imply that the ...

What is Behind the Recent Increase in Labor Force Participation?
Didem Tzemen and Jonathan L. Willis find that the recent increase in labor force participation is due not to more workers entering the labor force, but to fewer workers exiting it.

Job Polarization and the Natural Rate of Unemployment in the United States
I present a new estimate of the natural rate of unemployment in the United States that accounts for changes in the age, sex, and skill composition of the labor force. Using micro-level data from the Current Population Survey for the period 1994-2017, I find that the natural rate of unemployment declined by 0.5 percentage point since 1994 and currently stands at 4.5 percent. My projections show that ongoing demographic and technological changes could lower the trend rate further to 4.4 percent by the end of 2022.

How Many Workers Are Truly “Missing” from the Labor Force?
As of March 2022, the U.S. labor force participation rate remained one percentage point below its pre-pandemic level. After accounting for the effects of slower population growth and the aging of thepopulation in the past two years, I estimate that around 2 million workers are missing from the laborforce. Individuals age 65 and older, whose participation rates remain persistently below pre-pandemiclevels, constitute most of the missing labor force.

Were Teleworkable Jobs Pandemic-Proof?
While the majority of pandemic-related job losses have been in occupations where working from home was not possible, work-from-home or “teleworkable” jobs were not pandemic-proof. In addition, the number of teleworkable jobs lost and recovered differed by workers’ sex and education status. Both college-educated and non-college-educated women experienced larger employment losses and slower recoveries in teleworkable jobs than their male counterparts.
