@paninid @billseitz I guess it's right out of that same passage of Keynes. ("Thus the remedy for the boom is not a higher rate of interest but a lower rate of interest! For that may enable the so-called boom to last.")

But in my own view, interest rate policy is a bad lever to modulate demand, we'd be better off keeping short rates between 5% ± 2% and use other tools when that degree of "fine-tuning" isn't enough.
