Abstract This paper proposes an empirical method for estimating a long-run trend for the unemployment rate that is grounded in the modern theory of unemployment. I write down an unobserved components model and identify the cyclical and trend components of the underlying unemployment ‡ows, which in turn imply a time varying estimate of the unemployment trend, the natural rate. I identify a sharp decline in the out ‡ow rate -job …nding rate-since 2000, which was partly o¤set by the secular decline in the in ‡ow rate -separation rate -since 1980s, implying a relatively stable natural rate, currently at 6 percent. Numerical examples show that slower labor reallocation along with the weak output growth explains most of the persistence in unemployment since the Great Recession. Contrary to the business-cycle movements of the unemployment rate, a signi…cant fraction of the low-frequency variation can be accounted for by changes in the trend of the in ‡ows, especially prior to 1985. Finally, I highlight several desirable features of this natural rate concept that makes it a better measure than traditional counterparts. These include statistical precision, the signi…cance of required revisions to past estimates with subsequent data additions, policy relevance and its tight link with the theory.

Okun’s law is a statistical relationship between unemployment and GDP that is widely used as a rule of thumb for assessing the unemployment rate—why it might be at a certain level or where it might be headed, for example. Unfortunately, the Okun’s law relationship is not stable over time, which makes it potentially misleading as a rule of thumb.

This paper studies amplification of productivity shocks in labor markets through on-thejob-search. There is incomplete information about the quality of the employee-firm match which provides persistence in employment relationships and the rationale for on-the-job search. Amplification arises because productivity changes not only affect firms' probability of contacting unemployed workers but also of contacting already employed workers. Since higher productivity raises the value of all matches, even low quality matches become productive enough to survive in expansions. Therefore the measure of workers in low quality matches is greater when productivity is high, implying a higher probability of switching to another match. In other words, firms are more likely to meet employed workers in expansions and those they meet are more likely to accept firm's job offer because they are more likely to be employed in a low quality match. This introduces strongly procyclical labor market reallocation through procyclical job-to-job transitions. Simulations with a productivity process that is consistent with average labor productivity in the U.S. show that standard deviations for unemployment, vacancies and market tightness (vacancy-unemployment ratio) match the U.S. data. The model also reconciles the presence of endogenous separation with the negative correlation of unemployment and vacancies over business cycle frequencies (i.e. it is consistent with the Beveridge curve).

We use flows into and out of unemployment to estimate the unemployment rate over the next year. This approach produces less stark projections for the unemployment rate over the course of the next year than some of the more alarming projections that have been reported. Using our approach and assuming that the severest social-distancing measures will be lifted in June, we estimate that the unemployment rate will peak in May at about 16 percent but gradually decline thereafter and end the year at 7.5 percent.
