In 2001, Robert Litan and Lori Kletzer estimated that about 20% of displaced workers reemployed full-time would have had at least 2 years' tenure on their previous job and suffered a wage loss in the new one. The program would cost from $2 to $5 billion per year. This cost is estimated with a national unemployment rate between 4.2% and 4.9%. In 2012, the average national unemployment rate was 8.9%. Consequently, the projected cost would be higher if the program would be implemented today.
