Demographic origins of the startup deficit
We propose a simple explanation for the long-run decline in the U.S. startup rate. It originates from a slowdown in labor supply growth since the late 1970s, largely pre-determined by demographics. This channel can explain roughly 60 percent of the decline and why incumbent firm survival and average growth over the lifecycle have changed little. We show these results in a standard model of firm dynamics and test the mechanism using cross-state variation in labor supply growth. Finally, we show that a longer entry rate series imputed using historical establishment tabulations rises over the ...

Labor Market Policies During an Epidemic
We study the positive and normative implications of labor market policies that counteract the economic fallout from containment measures during an epidemic. We incorporate a standard epidemiological model into an equilibrium search model of the labor market to compare unemployment insurance (UI) expansions and payroll subsidies. In isolation, payroll subsidies that preserve match capital and enable a swift economic recovery are preferred over a cost-equivalent UI expansion. When considered jointly, however, a cost-equivalent optimal mix allocates 20 percent of the budget to payroll subsidies ...

Geographical reallocation and unemployment during the Great Recession: the role of the housing bust
This paper quantitatively evaluates the hypothesis that the housing bust in 2007 decreased geographical reallocation and increased the dispersion and level of unemployment during the Great Recession. We construct an equilibrium model of multiple locations with frictional housing and labor markets. When house prices fall, the amount of home equity declines, making it harder for homeowners to afford the down payment on a new house after moving. Consequently, the decline in house prices reduces migration and causes unemployment to rise differently in different locations. The model accounts for ...

The Long-Term Unemployed and the Wages of New Hires
This is the third in a series of blog posts on the topic of measuring labor market slack. In this post, we assess the relationships between short- and long-term unemployment and wages by comparing the differences in states’ experiences over the business cycle. While all states felt the impact of the Great Recession, some fared better than others. Consequently, it is possible to use differences in the composition and shifts of short- and long-term unemployment to determine whether short-term unemployment exerts a greater influence on wage determination. The results suggest that there is ...

The role of start-ups in structural transformation
The U.S. economy has been going through a striking structural transformation?the secular reallocation of employment across sectors?over the past several decades. We propose a decomposition framework to assess the contributions of various margins of firm dynamics to this shift. Using firm-level data, we find that at least 50 percent of the adjustment has been taking place along the entry margin, owing to sectors receiving shares of start-up employment that differ from their overall employment shares. The rest is mostly the result of life cycle differences across sectors. Declining overall ...

Understanding Permanent and Temporary Income Shocks
The earnings of 200 million U.S. workers change each year for various reasons. Some of these changes are anticipated while others are more unexpected. Although many of these changes may be due to pleasant surprises?such as receiving salary raises and promotions?others involve disappointments?such as falling into unemployment. Arguably, some of these factors have rather short-lived effects on an individual?s earnings, whereas others may have permanent effects. Many labor economists have been interested in these various shocks to earnings. How big are the more permanent shocks to earnings? How ...

Labor Market Shocks and Monetary Policy
We develop a heterogeneous agent New Keynesian model featuring a frictional labor market with on-the-job search to quantitatively study the positive and normative implications of employer-to-employer (EE) transitions for macroeconomic outcomes and monetary policy. We find that EE dynamics played an important role in shaping inflation dynamics during the Great Recession and COVID-19 recoveries, with the former exhibiting subdued EE transitions and inflation despite both episodes sharing similar unemployment dynamics. Optimal monetary policy prescribes a strong positive response to EE ...

Anatomy of Lifetime Earnings Inequality: Heterogeneity in Job Ladder Risk vs. Human Capital
We study the determinants of lifetime earnings (LE) inequality in the U.S. by focusing on job ladder dynamics and on-the-job learning as sources of wage growth. Using administrative data, we document that i) lower LE workers change jobs more often, which is mainly driven by nonemployment; ii) average annual earnings growth for job stayers is similar, around 2% in the bottom two-thirds of the LE distribution, whereas for job switchers it rises with LE; iii) top LE workers enjoy around 10% average earnings growth regardless of job switching. By targeting these facts, we estimate a structural ...

How Attached to the Labor Market Are the Long-Term Unemployed?
In this second post in our series on measuring labor market slack, we analyze the labor market outcomes of long-term unemployed workers to assess their employability and labor force attachment. If long-term unemployed workers are essentially nonparticipants, their job-finding prospects and attachment to the labor force should resemble those of nonparticipants who are not looking for a job and should differ considerably from those of short-term unemployed workers. Using data that allow us to follow workers over longer time periods, we find that differences in labor market outcomes between ...
How Should the Government Spend the Fiscal Budget during the COVID-19 Pandemic?
A mix of expanded unemployment insurance benefits and payroll subsidies to employers may be more effective in speeding up the recovery than implementing just one of those policies.
