World Productivity: 1996–2014
用新增长核算方法量化1996–2014年世界全要素生产率增长的驱动因素，发现全球生产率波动主要源于劳动力在国家和行业间的重新配置，新兴经济体的崛起抵消了发达经济体的生产率放缓，但2008年后这种抵消效应消失，全球生产率下降。
We use a new growth accounting method to quantify the drivers of world total factor productivity (TFP) growth during 1996–2014 and uncover four main results. World productivity growth is volatile from year to year. This mainly reflects reallocation of labor across country-industries. The contribution of country-industry level productivity growth to world productivity is relatively constant over time. This constancy masks that the increased importance of emerging economies offsets a productivity slowdown in advanced economies. After 2008, this offsetting effect dissipated and world TFP growth declined. These conclusions are robust to the inclusion of markups in the analysis.
