Americans are becoming more apt to quit their jobs, a government report showed on Tuesday, a sign that a stronger labor market and falling unemployment rate could result in healthier wage growth and inflation. Both wages and inflation tend to follow a rise in the quit rate by a couple of quarters, research from the Chicago Federal Reserve Bank shows. “Once the quit rate gets back to its pre-recession level, we could expect wage growth to be back to pre-recession levels within 6-12 months,” said Jason Faberman, a Chicago Fed researcher who co-authored the study.
