INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION INTELLECTUALLY UNPREPARED Volcker’smonetaristexperimentwontheearly1980sbattle againstinflation. 1980smonetarytheoryreferredalwaystomoney.

Kydland,Prescott,Lucas:allowtheeconomytooptimallyreactto shocks.Don’tworrytoomuchaboutbusinesscycles.Monetary policy‘over-emphasized.’ Rotemberg,Woodford,Taylor:totheextentwecanusemonetary stabilizationpolicyeffectively,interestraterulesareasensibletool. Result: WithZIRP... ...stabilizationpolicyrunsagroundintellectually. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION QUANTITATIVE EASING Near-zeropolicyrateshaveledtomuchdiscussionof “quantitativeeasing.” Goalsforthisaddress: Trytooffersomeclarityandperspectiveontheseissues. Prepareforthecomingeraofnear-zeropolicyratesglobally. Themes: 1 Littleintrinisicdifferencebetweennominalinterestratetargeting andmonetarytargeting. 2 Avoidingdeflationarytrapdynamicsmaydependonfiscal policy. 3 Globalaspectsofpolicycoordination: whattothink? 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 MONETARY IMPLEMENTATION WithintheNKmodel,anydesiredstabilizationpolicycouldbe implementedviaeitherinterestratemovementsormovements inthestockofmoney. Atsomelevel,thishastobetrue. Meaning: Wedonothavetoimplementviamoney... ...orevenrefertomoney... ...butwecanimplementviamoneyifdesired. Thisisanimportantconceptinthecurrentenvironment. Whydesirednow? Consider: Christiano,MottoandRostagno(2004)–“TheGreatDepression andtheFriedmanSchwartzhypothesis”:amonetarybaserule wouldhaveavoidedthedepression. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION “M” AND MONETARY POLICY IN THE NK MODEL ManyhavelookedforaroleformoneyintheNKframework. InthebasicNKmodel,itisnotnecessarytomakereferenceto money. Manyargumentsaboutthis. ButeveninthebasicNKmodel,youcanpursuestabilization policyviamovementsinthemoneystock.

DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION A CONCEPTUAL QUESTION TheNKmodelconsistsoffourequations. Afourthequationdescribesthedemandformoneyasafunction ofthenominalinterestrate. Itisadecoupledequation: Itisnotneededtofindthe equilibriumallocationsintheeconomy. Aquestionsometimesasked: isitnotpossibletoinvertthe moneydemandequation,expressingthesystemintermsofa monetaryruleinstead,withoutreferencetointerestratesatall? Answer: Itispossible,butthemonetaryruleisnotliketheones normallystudiedintheearlierliterature. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION PRELIMINARIES Assumetheinflationtargetiszero. AdoptWoodford’smoney-in-the-utilityfunctionspecification. Assumethatmoneydoesnotpayinterest. Allvariablesareexpressedasdeviationsfromtheirsteadystate equilibriumortargetvalues. Thereisnoassumptionconcerningthezerobound: Thisisa localanalysisforpositivenominalinterestrates. Thinkofnominalinterestratesasbeinglowbutpositive. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION FOUR EQUATIONS Considerfourequations: x t = E t x t+1 σ[r t E t π t+1 ]+e x,t (1) (cid:0) (cid:0) π t = κx t +βE t π t+1 +e π,t (2) r = ϕ π +ϕ x (3) t π t x t m = η x η r (4) t x t (cid:0) r t Equations(1)and(2)arestandard. Equation(3)isanadhocTaylorrulewithpolicyparameters ϕ π and ϕ . x Equation(4)isthemoneydemandrelationcomingfromthe money-in-the-utilityfunctionspecification. Normally,themoneydemandequation(4)isviewedas decoupled,andsoignored. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION DETERMINACY Substitutingequation(3)intoequation(1)createsa two-dimensionalsystemwithdeterminacycondition 1 β ϕ + (cid:0) ϕ >1.

Wecanchooseoptimalvaluesfor ϕ and ϕ subjecttothe π x determinacycondition. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION AN ALTERNATIVE ThrowouttheTaylorrule,equation(3). Invertthemoneydemandrelation: η x m r = x t (cid:0) t (6) t η r Substitute(6)into(1). SpecifyamoneysupplyruletoreplacetheTaylorrule: m = µ π +µ x (7) t π t x t withnewpolicyparametersµ andµ . π x Substitute(7)into(1). Thiscreatesatwo-dimensionalsystem,as before.

INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION RECENT DATA Deflationisarealpossibilityinthecurrentenvironment.

DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION DEFLATIONARY TRAPS TheJapaneseexperiencespawnedaliterature. Benhabib,Schmitt-Grohe,andUribe(2001,JET):“Theperilsof Taylorrules.” Theycombinedthefollowingfeatures: ATaylor-typepolicyrulewhichis‘active.’ Azeroboundonnominalinterestrates. AFisherrelation:rt =ρ+Etπ t+1 . Thesefeaturescombinetoproducea‘second’steadystateaway fromthetargetedsteadystate. Thisnewsteadystatehasinflationsubstantiallybelowtarget andverylownominalinterestrates. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION THE RISK OF A DEFLATIONARY TRAP TheBenhabibetal. storyseemsparticularlyrelevantinthe currentenvironment. Policyratesaremovinglowerworldwide. Alarge,globalshock. Whyworryaboutdeflation? Nominalcontracting. INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION A COMFORTING RESULT Onequestiontoaskwhentherearemultiplesteadystatesis whichsteadystateisstableunderlearningdynamics. Evans,Guse,andHonkapohja(2008,EER)didthisanalysisina NKmodel. Theyshowthatthetargetedsteadystateislocallystable,butnot globallystable,inthelearningdynamics. Thisiscomforting. Still,alargeshockcouldsendtheeconomyintowhattheycalla deflationaryspiral. Howtopreventthis? INTRODUCTION THEENDOFINTERESTRATERULES?

DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION AVOIDING DEFLATIONARY TRAPS: EGH FIG. 4 INTRODUCTION THEENDOFINTERESTRATERULES? DEFLATIONARYTRAPS GLOBALPOLICYCOORDINATION CONCLUSION GLOBAL POLICY Internationalpolicycoordinationisofcoursedifficult. Formonetarypolicy,modelsareonlyrecentlyavailable. Someliteraturesuggeststhatgainsfromcoordinationmaynot bethatlarge. Implication: don’tworryaboutalackofcoordination. INTRODUCTION THEENDOFINTERESTRATERULES?
