"Labor productivity has increased only 1/2 percent per year since 2010--the smallest five-year rate of increase since World War II and about one-fourth of the average postwar rate (figure 11). The slowdown in productivity has been worldwide and is evident even in countries that were little affected by the crisis (figure 12). Given the global nature of the phenomenon, it is unlikely that U.S.-specific factors are mainly responsible."

Hmmm
