I examine whether the cyclical behavior of unemployment has changed over the post WWII period. Specifically, I test whether cyclical movements in unemployment have become more persistent. Finding that they have, indeed, become more persistent, I then take some initial steps in explaining why. I find that the increase in persistence has affected private nonfarm payroll employment as well as unemployment and that increased persistence appears to be widespread across industries. At the same time, increased persistence owes primarily to greater persistence in job finding rates and greater persistence in unemployment among permanent job losers. This combination suggests that the welfare loss from cyclical increases in unemployment is becoming increasingly concentrated among permanent job losers who become unemployed for extended durations during cyclical downturns.
