" the central bank has very little direct traction when safe short-term rates are at the zero lower bound; maybe it can achieve something by buying lots of unconventional assets (“quantitative easing”), but its main hope of achieving anything is through “expectations management” — convincing both financial markets and players in the real economy that it will hold off much longer on tightening once the economy improves than they currently expect, which will lead to higher expected inflation and demand, and hence higher spending now."
any sort of nominal level target gets you that eh ?
