The former president of the Federal Reserve Alan Greenspan has earlier said that the US economy is facing a global problem of failure in productivity growth.

The research team at ANBOUND Consulting has noticed that in three months' time, Greenspan has warned on the productivity problems for the third time, grasping the key problem to the current global economic downturn.

We have earlier analyzed that productivity depends on both inputs and outputs but excess global capital have also resulted in the reduction in productivity.

Besides, the aging global population is another important factor causing the continuous reduction in global production; this will not only bury the economic and social developments in various countries but also continue to bring down the efforts in improving the global productivity.
