Technological progress and the global decline in the manufacturing labour share
利用86个国家1963-2020年制造业数据，研究发现国内外技术进步自1990年以来降低了高收入国家的劳动份额，但提高了中低收入国家的劳动份额，且低收入国家的正向效应由高研发密集型企业驱动。
Using manufacturing data for a panel of 86 low- , middle-, and high-income countries over the period 1963–2020, this study investigates the effects of domestic and foreign technological progress on the labour share dynamics in low- and high-tech manufacturing. We find that the increase in domestic and, in particular, foreign technological progress since approximately 1990, has reduced the labour share in high-income countries and contributed to an increase in the labour share in middle- and low-income countries. The positive effects in the low-income countries have been driven by high R&D-intensity firms. Overall, we find that estimates for the US and other high-income countries cannot be used to project the underlying drivers of labour shares in the middle- and low-income countries.
