According to a report released by The Conference Board, the global business membership and research organization, productivity growth weakened substantially across the globe in 2011, with the drop-off most dramatic in advanced economies. The 2012 Productivity Brief, based on data from The Conference Board Total Economy Database™, shows productivity - typically measured as output per person employed or hour worked - increased at a much slower rate in 2011 than most economists had predicted, with the trend likely to continue into 2012.
