When IT technology increased productivity significantly, there are more goods and services needed to be consume for the economy not slipping into recession.
Are you serious? You think productivity gain leads to recession?Greenspan gave his famous speech of "irrational exuberance" in 1997. But some people argued that it was not bubble but properly reflected the fundamental increases in assets' potential future incomes. What should Greenspan have done at that time? Increasing the interest rate preemptively enough without clear signs of inflation?
I think Greenspan should have done nothing, at that time, before that time, and after that time. Just let the market determine price of money (interest rate).
Right. Let's stop open market operations, close the discount window, or just shut down the entire Fed Reserve. Go back to the Gold Standard, or allow private banks issue their own monies, like what happened during the civil war. Perhaps even Milton Friedman would turn in his grave...
As the ultimate supplier of money, central bank doing nothing is doing something.
