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.

Trends in the Labor Share Post-2000
The labor share of income declined sharply in the United States from 2000 to 2010 but seems to have stabilized since 2010. We examine aggregate trends in the labor share and show that the 2000?10 decline was driven by declines in the fraction of income paid to workers in all industries. The stabilization in the labor share after 2010 mostly reflects an increased share of services industries income paid to workers.

Under-investment in state capacity: the role of inequality and political instability
Existing studies have shown that the state's ability to tax, also known as fiscal capacity, is positively related to economic development. In this paper, we analyze the determinants of the government's decision to invest in state capacity, which involves a trade-off between present consumption and the ability to collect more taxes in the future. Using a model, we highlight some political and economic dimensions of this decision and conclude that political stability, democracy, income inequality, as well as the valuation of public goods relative to private goods, are important variables to ...

The Uneven Recovery in Prime-Age Labor Force Participation
The labor force participation rate of prime-age individuals (age 25 to 54) in the United States declined dramatically during and after the Great Recession. Although the prime-age labor force participation rate has been increasing since mid-2015, it remains below its pre-recession level. Understanding the reasons for this decline requires detailed analysis; aggregate statistics on labor force participation may mask potential differences in labor market outcomes by sex or educational attainment. Didem Tzemen and Thao Tran identify these differences, finding that prime-age men and women without ...

The Cyclical Behavior of Labor Force Participation
We document that labor force participation declines in the short run following a positive technology shock. The countercyclical response of labor force participation to a technology shock contrasts with the well documented mild procyclical behavior of labor force participation in the business cycle. In a search model of the labor market that incorporates a participation choice, we show that a positive technology shock reduces labor force participation in the short run under a reasonable calibration. In the calibrated model, discount factor shocks induce a procyclical response of labor force ...

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.

A Strong Labor Market Has Narrowed Gaps in Participation and Employment between Black and White Non-College Men
Black and Hispanic workers faced disproportionately larger declines in labor force participation than white workers during the pandemic-led recession. This gap appears consistent with previous recessions: the labor market outcomes of racial and ethnic minorities tend to deteriorate more than those of white workers during recessions, widening gaps in participation, employment, and wages during downturns. However, the labor market has since recovered, with employment rising above pre-pandemic levels. Have gaps in labor market outcomes between Black and white workers narrowed?Didem Tüzemen and ...
