2 . INTRODUCTION Through he lenses of a wo-counry dynamc sochasc general equlbrum (dsge) model hs chaper analyzes mulple underlyng condons ha yeld an equlbrum n whch usa normalzes s moneary polcy by ncreasng he Federal Reserve funds rae. The queson ha I address s: Wha hose condons mply for emergng markes and n parcular for Mexco? I buld on he real busness cycle model developed by Hernandez and Leblebcoğlu (26) o add moneary feaures. The model feaures several channels for he nernaonal ransmsson of shocks among hem: he exchange rae channel nernaonal bank lendng capal flows usa and eme polcy raes and nernaonal rade. As shown frs n Hernandez and Leblebcoğlu (26) hose channels are crucal o capurng he nernaonal ransmsson of shocks. In sharp conras Jusnano and Preson (2) show ha an esmaed sandard small open economy model fals o capure he nernaonal ransmsson of shocks from usa o a small open economy Canada n ha case. In order o dscplne he mulple channels modeled I use 2 me seres from 2Q o 25Q2 for usa and Mexco o esmae he model. The model n-sample predcons are n lne wh he daa. In parcular he model addresses very successfully he Jusnano and Preson (2) crcsm of esmaed dsge models n ha hs model predcs cross-counry correlaons conssen wh he daa. Wh he purpose of produce polcy normalzaon scenaros I use he esmaed model o smulae mllons of pahs for he full economy for he las wo quarers of 25 whch are ou of sample. Then from he smulaed pahs I only consder hose n whch usa neres rae ncreases n one or boh quarers. In he average polcy normalzaon scenaro he model predcs condons n usa ha lead o a polcy rae ncrease of 25 bass pons only wh an average growh of 2.4% n 25. For Mexco hose condons mply a growh of 2.8%. The ncrease n us rae calls for an ncrease n Mexco s polcy rae. Mexco s polcy rae hke conans he ongong deprecaon of he real exchange rae and sablzes nflaon. The res of he chaper s organzed as follows: Secon 2 presens he wo-counry moneary dsge model Secon 3 shows he scenaro analyss and Secon 4 concludes. 6 K. Hernández

3 2. THE MODEL In hs secon I show he man ngredens of he wo-counry dsge moneary model. The economy feaures domesc (eme) and foregn (us) households wo secors of fnal goods producers (radable and nonradable) n each economy. Followng Chrsano e al. (24) also feaures a capal owner enrepreneurs and a fnancal nermedary addonally has a fscal and a moneary auhores. 2. Households Boh he domesc and foregn households supply labor o he radable and non-radable secors and rade bonds wh he res of he world. The preferences are of he ghh Greenwood e al. (988) ype: U = = ξ β ς + η C ϑ C ϕc L + η ς where C s consumpon L s labor ξ C s a preference shock φ ( ) s a hab parameer η deermnes he Frsch elascy and ϑ s a preference parameer. The compose labor L s a ces baske wh labor n he radable secor L T and labor n he nonradable secor L NT wh he elascy of subsuon χ. The consumpon baske C s defned by a ces aggregaor for he radable consumpon baske C T and he nonradable consumpon baske C NT wh he elascy of subsuon θ. In urn he ces radable consumpon baske s formed by consumpon of he foregn good C F he domesc good C H and a consumpon good ha comes from he res of he world C O.

They can be ndexed by z [ ]. Frms are monopolsc compeve and se prces subec o a Calvo prcng scheme.e. frms can change prces only when hey receve a random sgnal ha arrves wh probably ( C) n every perod. In he perods when he producer does no receve he random sgnal aduss he nomnal prce accordng o he ndexaon rule: ι 3 P () z π P () z T NT = ( ) { } where P (z) s he nomnal prce of he varey z n secor π denoes aggregae nflaon and ι [ ] s he ndexaon parameer. The frm z faces a demand of he form P z () 4 Y () z = Y P where λ follows an AR() process specfed below P s he aggregae prce ndex n secor and Y denoes oal demand Technology Frms n he radable secor have he echnology 5 Y ξ u K L λ α α T AT H = ( ) where u s he capal ulzaon rae α ( ) and ξ AT denoes he producvy shock. In he non-radable secor frms face he echnology 6 Y = ξ L NT AN NT where ξ AN denoes he producvy process. I allow for he secoral echnology shocks o be correlaed 8 K. Hernández

Frms face a workng capal consran as n Neumeyer and Perr (25) and Urbe and Yue (26).

6 2.3 Capal Producer Enrepreneurs and he Fnancal Inermedary Followng Chrsano e al. (24) he capals bulds new raw capal wh he echnology 8 K = δ K ξii 2 ( ) + φi I 2 I and sells o he enrepreneurs where I s nvesmen ξ I s an nvesmen shock and φ I deermnes he convex adusmen cos of nvesmen. The new capal s sold o he enrepreneur a he prce Q k. The enrepreneur receves a producvy shock ω wh ln ( ω) ( σ ω ) ha ransforms he raw capal n effecve capal ωk. The effecve capal s rened o he fnal good producer and afer s used n producon s sold back o he capals. The ( ) k k reurn on capal s ωr k k ur a( u )+ Q δ where R = k and Q k au ( ):= r exp ( σa ( u )) σ gves he ulzaon adusmen cos a ( σ a > ) and δ s he deprecaon rae. The opmal conrac maxmzes he expeced value of he enrepreneur subec o a zero prof condon for he nermedary. The opmaly condons mply: 9 Γ = + [ ] { Γ µ G } Γ R k k R { Γ+ µ G+ } R+ N N R+ ( L )= L { Γ µ G} R where ω s a hreshold n he producvy shock ha separaes hose ω ha can repay he loan and hose ha defaul F( ω ) df ( ω ) and ω G( ω ) ωdf ( ω ) Γ( ω )= F( ω ) ω + G( ω ) and Γ and G are he correspondng dervaves wh respec oω. 2.4 Fscal and Moneary Polces The governmen purchases goods only from he domesc raded and nonraded secors whch are combned n a compose good smlar o he consumer s consumpon baske. The governmen spendng follows he rule k 2 K. Hernández

7 Gov Gov Y Y = ( ) ψgy ξ G where ξ G s an exogenous shock and ψ GY s a reacon coeffcen. The moneary auhory follows he Taylor rule: p p R = ρ R + ρ π + ρ Y + r π y mp where ρ r s he smoohng coeffcen and mp s.. d. monearypolcy shock. 3. ESTIMATION AND MONETARY POLICY SCENARIO DESIGN As a general rule I esmae all he parameers ha govern shocks and frcons n he model. I use he Random Walk Meropols-Hasng (rwmh) algorhm as descrbed n An and Schorfhede (27) n parcular o solve he model I use he algorhm dscussed n Hernandez (23) only wh he soluon mehod of Klen (2). I use quarerly daa for Mexco and usa from 2Q o 25Q2. The me seres used are: p Morgan emb + Spread Mexco spread beween baa and -year Treasury for usa shadow federal funds rae for usa he 9-day cees rae for Mexco gdp-deflaor nflaon for Mexco and he usa gdp growh for Mexco and he usa consumpon growh for Mexco and usa nvesmen growh for Mexco and usa blaeral mpors growh for Mexco blaeral expors growh for Mexco gdp-deflaor-based blaeral real exchange rae deprecaon governmen spendng growh for Mexco and usa non-blaeral rade over gdp for Mexco and usa and growh n per capa work hours for usa. 3. The Transmsson Mechansm of us Shocks Fgure shows he mpulse responses of key Mexco s varables o us shocks. Tha s shows he ransmsson mechansms of usa shocks no he Mexcan economy. Frs an expansonary us preference shock ncreases Mexco s gdp nflaon neres raes and deprecaes he peso. The preference shock n usa acs as a usa demand The Transmsson of us Moneary Polcy Normalzaon 2

8 shock ha ncreases gdp n usa generaes nflaon n usa and as a resul he us moneary polcy has o ncrease he polcy rae. Gven he us rae hke he peso deprecaes whch ogeher wh he larger us demand for Mexcan goods smulaes ne expors n Mexco and hus gdp n Mexco ges smulaed. Tha s he rade channel s of key mporance for he nernaonal ransmsson of hese ypes of shocks. In urn he deprecaon pass-hrough o domesc prces and s nflaonary for Mexco; wh hgher gdp a more deprecaed peso and hgher nflaon he moneary polcy response n Mexco s o ncrease polcy raes o resore he long-erm equlbrum. Second a us echnology shock ncreases us gdp lowers us nflaon and drops he real us neres rae as n any sandard dsge model. In urn he fnancal channel n Mexco akes more relevance for he nernaonal ransmsson of hese ype of shocks because lower nernaonal raes make he us echnology shock o ac as a Mexco echnology shock. Tha s lowers he margnal cos of producon n Mexco as producon fnancng coss are lower. In urn lower margnal coss n Mexco lower nflaon and smulae gdp wh hgher ne expors and as a resul he peso ges apprecaed o help resore he long-erm equlbrum. Fnally a moneary polcy shock n usa s conraconary for usa and lowers us nflaon. An neres rae hke n usa deprecaes he peso whch s passed-hrough o domesc prces n Mexco and nflaon hkes; as a resul he moneary polcy ncreases he polcy rae. The lower us demand for Mexcan goods despe he deprecaed peso drops domesc gdp. Of course hese mpulse responses are ceers parbus exercses amed o undersand he ransmsson mechansms of he model. The acual condons under whch one should expec a hke of us neres raes mus be he end resul of realzaons of varous shocks ha deermne a sae of he us economy ha calls for a less accommodave moneary polcy. The nex subsecon addresses ha ssue. 3.2 Scenaro Analyss The scenaro analyss s conduced as follows.

12 4. CONCLUSIONS Ths chaper presens a dsge model for he Mexcan economy ha conans mporan channels for he nernaonal ransmsson of us shocks o Mexco. Among he ransmsson channels are: he exchange rae channel nernaonal bank lendng capal flows moneary polcy raes and nernaonal blaeral rade. Based on a Bayesan esmaon of he deep parameers of he model I smulae mllons of scenaros under whch he us moneary polcy rae would ncrease n he las wo (ou of sample) quarers of 25. Those scenaros are bul by drawng sochasc macroeconomc shocks for he whole economy ha s usa Mexco and oher nernaonal shocks are smulaneously consdered. Ou of hose sochasc draws I only consder hose ha yeld an equlbrum n whch he us moneary polcy rae ncreases as a resul. In average hose equlbra are characerzed by favorable gdp growh n boh counres a modes ncrease n he Federal Reserve funds rae and a more han one-oone response n Mexco s polcy rae. The general concluson s ha hose condons ha are needed for he normalzaon of us moneary polcy are good condons for boh usa and Mexco.
