I think it's the most serious problem that confronts not only the United States but the world at large and more exactly the developed world especially. American productivity is not significantly different from zero growth in the last 6 or 8 quarters. And the cause of that, if you work backwards through the causative chain is capital investment has been inadequate to fund the amount of assets that you need.The interviewer, Tom Keene responded with “There was a moment when we were bewildered by why nation's productivity was so good and America running on all cylinders. It is a distant memory.”
Why has productivity fallen and what does it mean? The answer lies in Hayek’s Ricardo Effect. Profits in consumer goods sectors will peak near the end of the expansion phase of a business cycle. Profits rise because investment in capital goods sectors has increased employment, and therefore demand for consumer goods before new consumer goods arrive on the market. Prices and profits rise in step.
