A November 2011 report by the Congressional Budget Office found that even if unemployment benefits convince some unemployed to ignore job openings, these openings were quickly filled by new entrants into the labor market. A survey of studies on unemployment insurance's effect on employment by the Political Economy Research Institute found that unemployed who collected benefits did not find themselves out of work longer than those who "didn't" have unemployment benefits; and that unemployed workers did not search for work more or reduce their wage expectations once their benefits ran out.
