Advance Notice, Job Search, and Postdisplacement Earnings
研究发现，被裁员时收到法定提前通知的工人，3至5年后收入比未收到者高约10%，但这一差异可能源于雇主同时提供的其他就业援助，而非通知本身。
Three to 5 years after job displacements, workers receiving the advance notice mandated by current law earn approximately 10% more than their nonnotified counterparts. This differential is not the result of firms systematically notifying persons with favorable reemployment prospects—early warnings are disproportionately obtained by individuals expected to earn relatively low wages in subsequent employment. It is not clear, however, whether prenotification has a causal effect. The notification differential may occur because the advance notice is frequently provided by employers offering other kinds of adjustment assistance such as job counseling, skill retraining, supple¬mental unemployment benefits, or outplacement assistance.
