Americans Do IT Better: US Multinationals and the Productivity Miracle
研究发现，1995年后美国生产率加速增长，在欧美国跨国公司也实现了“生产率奇迹”，其IT生产率高于非美跨国公司，这主要归因于更严格的“人员管理”实践。
US productivity growth accelerated after 1995 (unlike Europe's), particularly in sectors that intensively use information technologies (IT). Using two new micro panel datasets we show that US multinationals operating in Europe also experienced a “productivity miracle.” US multinationals obtained higher productivity from IT than non-US multinationals, particularly in the same sectors responsible for the US productivity acceleration. Furthermore, establishments taken over by US multinationals (but not by non-US multinationals) increased the productivity of their IT. Combining pan-European firm-level IT data with our management practices survey, we find that the US IT related productivity advantage is primarily due to its tougher “people management” practices.
