"New data compel a new view of events in the labor market during a recession. Unemployment rises almost entirely because jobs become harder to find. Recessions involve little increase in the flow of workers out of jobs. Another important finding from new data is that a large fraction of workers departing jobs move to new jobs without intervening unemployment. I develop estimates of separation rates and job-finding rates for the past 50 years, using historical data informed by detailed recent data. The separation rate is nearly constant while the job-finding rate shows high volatility at business-cycle and lower frequencies. I review modern theories of fluctuations in the job-finding rate. The challenge to these theories is to identify mechanisms in the labor market that amplify small changes in driving forces into fluctuations in the job-finding rate of the high magnitude...
