How to make sense of the productivity slowdown in OECD countries?

The OECD is characterised by a significant slowdown in productivity gains and technological progress. And yet: Companies are becoming more automated; Corporate investment in new technologies is growing; R&D spending is growing; The education level of the labour force continues to rise. The productivity slowdown cannot be understood if one does not see that the net corporate investment rate has fallen considerably (which is not the case with the gross investment rate) due to the increase in consumption of fixed capital (capital depreciation). Companies have not invested sufficiently to offset the acceleration in capital obsolescence, hence the slowdown in productivity gains.
