Conclusion: How Low Will the Unemployment Rate Go?
A major theme of the posts in our labor market series has been that the outflows from unemployment, either into employment or out of the labor force, have been the primary determinant of unemployment rate dynamics in long expansions. The key to the importance of outflows is that within long expansions there have not been adverse shocks that lead to a burst of job losses. To illustrate the power of this mechanism, we presented simulations in a previous post that were based on the movements in the outflow and inflow rates in the previous three expansions. These simulated paths show the ...

Search Frictions, Labor Supply, and the Asymmetric Business Cycle
We develop a business cycle model with search frictions in the labor market and a labor supply decision along the extensive margin that yields cyclical asymmetry between peaks and troughs of the unemployment rate and symmetric fluctuations of the labor force participation rate as in the U.S. data. We calibrate the model and find that cyclical changes in the extent of search frictions are solely responsible for the peak-trough asymmetry. Participation decisions do not generate asymmetry but contribute to the fluctuations in search frictions by changing the size and composition of the pool of ...

The Role of News about TFP in U.S. Recessions and Booms
We develop a general equilibrium model to study the historical contribution of TFP news to the U.S. business cycle. Hiring frictions provide incentives for firms to start hiring ahead of an anticipated improvement in technology. For plausibly calibrated hiring costs, employment gradually rises in response to positive TFP news shocks even under standard preferences. TFP news shocks are identified mainly by current and expected unemployment rates since periods in which average unemployment is relatively high (low) are also periods in which average TFP growth is slow (fast). We work out the ...

How Large were the Effects of Emergency and Extended Benefits on Unemployment during the Great Recession and its Aftermath?
This paper presents estimates of the effect of unemployment benefit extensions during the Great Recession on unemployment and labor force participation. Unlike many recent studies of this subject, our estimates, following the work of Hagedorn, Karahan, Manovskii, and Mitman (2016), are inclusive of the effects of benefit extensions on employer, as well as, worker behavior. To identify the effect of benefit extensions, we use plausibly exogenous changes in the rules governing benefit extensions and their differential effects on the maximum duration of benefits across states. We find that the ...

Declining Labor Force Attachment and Downward Trends in Unemployment and Participation
The U.S. labor market witnessed two apparently unrelated secular movements in the last 30 years: a decline in unemployment between the early 1980s and the early 2000s, and a decline in participation since the early 2000s. Using CPS micro data and a stock-flow accounting framework, we show that a substantial, and hitherto unnoticed, factor behind both trends is a decline in the share of nonparticipants who are at the margin of participation. A lower share of marginal nonparticipants implies a lower unemployment rate, because marginal nonparticipants enter the labor force mostly through ...
