INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION
A BENCHMARK MODEL
BecauseofZIRP,thereiscurrentlyalotofdiscussionabout
quantitatively-basedmonetarypolicy.
ButsinceTaylor(1993),thediscussionhasmovedtheotherway,
towardinterestraterules.
“Rationalizingwhatcentralbanksalreadydo.”
Thrustofthatdiscussion: onedoesnothavetorefertomoney
whenimplementingmonetarypolicy.
Tothinkaboutthis:
ConsiderthebasicmodelfromWoodford(2003,InterestandPrices,
PrincetonUniversityPress).
Thinkofshort-termnominalinterestratesasbeinglow,butnot
zero.
INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION
