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 ...

Self-employment and health care reform: evidence from Massachusetts
We study the e ect of the Massachusetts health care reform on the uninsured rate and the self-employment rate in the state. The reform required all individuals to obtain health insurance, required most employers to o er health insurance to their employees, formed a private marketplace that o ered subsidized health insurance options and ex- panded public insurance. We examine data from the Current Population Survey (CPS)for 1994-2012 and its Annual Social and Economic (ASEC) Supplement for 1996-2013. We show that the reform led to a dramatic reduction in the state's uninsured rate due to ...

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.

Commodity dependence and fiscal capacity
This paper shows that higher commodity dependence reduces the government's incentive to invest in fiscal capacity. After developing a model that makes this prediction, evidence is provided supporting the view that countries more dependent on commodities (whose rents can be easily appropriated by the government, such as oil) have weaker fiscal capacity. Also, fiscal capacity is found to improve less over time in commodity dependent countries relative to countries where commodity exports play a less relevant role. These empirical results are obtained in a panel dataset with estimators that ...

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 ...

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 ...

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 ...

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 ...

Health-care reform or labor market reform? A quantitative analysis of the affordable care act
An equilibrium model with firm and worker heterogeneity is constructed to analyze labor market and welfare implications of the Patient Protection and Affordable Care Act, commonly called the Affordable Care Act (ACA). The authors? model implies a significant reduction in the uninsured rate from 22.6 percent to 5.6 percent. The model predicts a moderate positive welfare gain from the ACA because of the redistribution of income through health insurance subsidies at the exchange as well as the Medicaid expansion. About 2.1 million more part-time jobs are created under the ACA at the expense of ...

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 ...
