CBO report, February 4, 2014: “The deep recession that began in December 2007, when the economy began to contract, and ended in June 2009, when the economy began to expand again, has had a lasting effect on the labor market. More than four and a half years after the end of the recession, employment has risen sluggishly—much more slowly than it grew, on average, during the four previous recoveries that lasted more than one year. At the same time, the unemployment rate has fallen only partway back to its prerecession level, and a significant part of that improvement is attributable to a decline in labor force participation that has occurred as an unusually large number of people have stopped looking for work. To a large degree, the slow recovery of the labor market reflects the slow growth in the demand for goods and services, and hence gross domestic product (GDP). CBO estimates that GDP was 7½ percent smaller than potential (maximum sustainable) GDP at the end of the recession; by the end of 2013, less than one-half of that gap had been closed. With output growing so slowly, payrolls have increased slowly as well—and the slack in the labor market that can be seen in the elevated unemployment rate and part of the reduction in the rate of labor force participation mirrors the gap between actual and potential GDP. To a smaller degree, the slow recovery of the labor market is the result of structural factors that stem from the recession and the slow recovery of output but that are not directly related to the economy’s current cyclical weakness. For example, an exceptionally large number of people have been unemployed for long periods, and the stigma attached to their long-term unemployment, along with a possible erosion of their job skills, has made it difficult for them to find new work.”
