The U.S. economy's slow and jobless recovery from the Great Recession has prompted a variety of explanations for the labor market's weak performance. One common argument suggests that a mismatch exists between the sectors with job openings and the sectors where unemployed workers search. As a result, vacancies go unfilled, and the unemployed do not re-enter the workforce. If sectoral mismatch is the source of the jobless recovery, then the challenge is to equip workers with skills that can help them transition to jobs in growing sectors.
