Advance Layoff Notices and Labor Market Forecasting


We collect rich establishment-level data about advance layoff notices filed under the Worker Adjustment and Retraining Notification (WARN) Act since January 1990. We present in-sample evidence that the number of workers affected by WARN notices leads state-level initial unemployment insurance claims, changes in the unemployment rate, and changes in private employment. The effects are strongest at the one and two-month horizons. After aggregating state-level information to a national-level “WARN factor” using a dynamic factor model, we find that the factor substantially improves out-of-sample forecasts of changes of manufacturing employment in real time.
