<Li> "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 71⁄2 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 ." </Li> <Li> "Of the roughly 2 percentage - point net increase in the rate of unemployment between the end of 2007 and the end of 2013, about 1 percentage point was the result of cyclical weakness in the demand for goods and services, and about 1 percentage point arose from structural factors; those factors are chiefly the stigma workers face and the erosion of skills that can stem from long - term unemployment (together worth about one - half of a percentage point of increase in the unemployment rate) and a decrease in the efficiency with which employers are filling vacancies (probably at least in part as a result of mismatches in skills and locations, and also worth about one - half of a percentage point of the increase in the unemployment rate)." </Li> <Li> "Of the roughly 3 percentage - point net decline in the labor force participation rate between the end of 2007 and the end of 2013, about 11⁄2 percentage points was the result of long - term trends (primarily the aging of the population), about 1 percentage point was the result of temporary weakness in employment prospects and wages, and about one - half of a percentage point was attributable to unusual aspects of the slow recovery that led workers to become discouraged and permanently drop out of the labor force ." </Li> <Li> "Employment at the end of 2013 was about 6 million jobs short of where it would be if the unemployment rate had returned to its prerecession level and if the participation rate had risen to the level it would have attained without the current cyclical weakness . Those factors account roughly equally for the shortfall ." </Li>
