Inroducion How do markes arrive a prices? There is perhaps no quesion more cenral o economics. This paper focuses on price formaion in financial markes, where he quesion looms large: How, if a all, is news abou macroeconomic fundamenals incorporaed in pricing socks, bonds and foreign exchange? Unforunaely, he process of price discovery in financial markes remains poorly undersood. Tradiional efficien markes hinking suggess ha asse prices should compleely and insananeously reflec movemens in underlying fundamenals. Conversely, ohers feel ha asse prices and fundamenals may be largely and rouinely disconneced. Experiences such as he lae 1990s U.S. marke bubble would seem o suppor ha view, ye simulaneously i seems clear ha financial marke paricipans pay a grea deal of aenion o daa on underlying economic fundamenals. The noable difficuly of empirically mapping he links beween economic fundamenals and asse prices is indeed sriking. The cenral price-discovery quesion has many dimensions and nuances. How quickly, and wih wha paerns, do adjusmens o news occur? Does announcemen iming maer? Are he magniudes of effecs similar for good news and bad news, or, for example, do markes reac more vigorously o bad news han o good news? Quie apar from he direc effec of news on asses prices, wha is is effec on financial marke volailiy? Do he effecs of news on prices and volailiy vary across asses and counries, and wha are he links? Are here readily idenifiable herd behavior and/or conagion effecs? Do news effecs vary over he business cycle? Jus as he cenral quesion of price discovery has many dimensions and nuances, so oo does a full answer. Appropriaely hen, dozens perhaps hundreds of empirical papers chip away a he price discovery quesion, bu mos fall shor of our goals in one way or anoher. Some examine he connecion beween macroeconomic news announcemens and subsequen movemens in asse prices, bu only for a single asse class and counry (e.g., Balduzzi e al., 2001, who sudy he U.S. bond marke). Ohers examine muliple asse classes bu only a single counry (e.g., Boyd e al., 2005, who sudy U.S. sock and bond markes). Sill ohers examine muliple counries bu only a single asse class (e.g., Andersen e al., 2003b, who sudy several major U.S. dollar exchange raes). Now, however, professional aenion is urning oward muliple counries and asse classes. 1 Our paper is firmly in ha radiion. We progress by sudying a broad se of counries and asse classes, characerizing he join response of foreign exchange markes as well as he domesic and foreign sock and bond markes o real-ime U.S. macroeconomic news. We simulaneously 1 Noably, for example, in conemporaneous and independen work, Faus, Rogers, Wang, and Wrigh (2007) use he lens of uncovered ineres rae pariy o examine he news responses of bond yield curves (in he U.S., Germany and he U.K.) and he corresponding dollar exchange raes.

High-frequency reurns around macroeconomic news announcemens Table 2 repors summary saisics for he five-minue reurn series around he announcemen imes. Since our news announcemen regressions are based on he period ranging from en minues before o one-and-a-half hours afer an announcemen, we le he sample cover his se of reurns only. Moreover, o provide a meaningful benchmark for he subsequen resuls based on simulaneous esimaion across all he markes, we furher resric he sample for all conracs o July 1, 1998 o December 31, 2002, he period available for he shores series, namely he European markes. The average five-minue reurn for each of he nine markes is, as expeced, exremely close o zero. However, he (absolue) size of he larges five-minue reurns is noeworhy, wih he exreme reurn even being abou en sandard deviaions or more removed from he sample mean for all markes. For he S&P500 and he DJE hese exreme moves exceed wo percen. This immediaely suggess ha macroeconomic news does move he markes. 5 The summary saisics confirm he usual rank ordering in erms of volailiy, wih sock markes being he mos volaile, followed by foreign exchange raes, and hen fixed income. The only excepion o his rule is he U.S. T-Bond marke, for which he uncondiional reurn sandard deviaion acually exceeds he sandard deviaions for he hree exchange raes. This is likely a consequence of he fac ha he T-Bond marke, as discussed furher below, reacs mos srongly o macroeconomic news. To provide a sense of he comovemens among he asse markes during news announcemen imes, Table 3 repors uncondiional sample correlaions. All correlaions wihin each of he hree asse classes are posiive. For insance, he sock marke correlaions range from a low of 0.42 beween he S&P500 and he FTSE 100, o a high of 0.54 for he FTSE 100 and he DJE. Similarly, he correlaion beween he reurns for he U.S. T-Bond and he Briish Long Gil is 0.53, while he Gil and German Euro Bobl correlaion is 0.61. The posiive bond marke crosscorrelaions during U.S. macroeconomic news announcemen imes mach sandard heoreical predicions, such as hose of Lucas (1982). 6 The posiive equiy marke cross-correlaions are 4 Five-minue reurns srike a reasonable balance beween confounding marke microsrucure effecs by sampling oo frequenly and blurring specific price reacions when sampling oo infrequenly; see e.g., he relaed discussions in Andersen e al. (2003b), Bandi and Russell (2004), Hansen and Lunde (2006) and Aï-Sahalia, Mykland and Zhang (2005), among ohers. 5 This is consisen wih Fair (2002), who finds mos large moves in high-frequency S&P500 reurns o be readily idenified wih U.S. macroeconomic news announcemens. Similar resuls for he DM/$ foreign exchange and U.S. T- Bond markes are repored in Andersen and Bollerslev (1998) and Bollerslev, Cai and Song (2000). 6 Alernaively, he posiive bond marke correlaion is also consisen wih he U.S. ineres rae effecively serving as he world ineres rae, as assumed in numerous heoreical models; see also Blanchard and Summers (1984) and he more recen discussion in Chinn and Frankel (2004).

Sock marke prices around he world would end o be posiively correlaed if he discoun rae is he dominan effec or if he domesic and foreign real oupu and/or moneary shocks are posiively correlaed. 7 The cross correlaions beween he differen asse ypes are generally much smaller han he cross correlaions wihin he same asse caegory across counries. Given our American exchange rae quoaion convenion ($/Euro, $/Pound, $/Yen), he negaive correlaions beween he S&P500 and he exchange raes imply ha U.S. macroeconomic news affecs he Dollar and he equiy marke in he same direcion. Ineresingly, a Dollar appreciaion also is associaed wih sock marke increases abroad, even hough one may expec he Dollar o depreciae agains he Pound (Euro) when he FTSE 100 (DJE) prices are rising. This again suggess ha he U.S. macroeconomic fundamenals exer a dominan effec during he news announcemen period. I also serves as a warning ha i may be imporan o conrol explicily for macroeconomic fundamenals when inerpreing asse marke correlaions. Subsequenly we aemp o do so in a simulaneous equaions seing. 2.3. Correlaions in expansions vs. conracions I is ineresing o ask wheher he ineracions among asse reurns and heir responses o macroeconomic fundamenals vary sysemaically across he business cycle. For a preliminary look a his issue, he boom panels in Table 3 repor he uncondiional correlaions separaely for he expansion period from July 1998 hrough February 2001 and he conracion period from March 2001 hrough December 2002. 8 During he expansion, he sock-bond correlaions are posiive albei small, whereas during he conracion hey are negaive and large. We canno claim his as a general paern, as we only have daa for one expansion and one conracion. Sill, one possible explanaion is ha he cash flow effec dominaes during conracions while he discoun effec dominaes in expansions (due o cenral bank policy), producing posiive sock-bond reurn correlaions during expansions and negaive in conracions, in confirmaion of he seminal conribuion of Boyd, Jagannahan, and Hu (2005). In wha follows, we explore ha possibiliy in deph. 3. Asse reurns and macroeconomic surprises: basic resuls Here we characerize he dynamic effecs of U.S. macroeconomic news announcemens for each of our nine asse markes. We begin by describing our measuremen of macroeconomic 7 Alhough he high posiive conemporaneous correlaion across counries may be explained by he common bond marke response o U.S. macroeconomic news, a number of oher influences, including marke microsrucure, conagion, and cross-marke hedging effecs, as discussed for example in Fleming, Kirby and Osdiek (1998), could also accoun for he high-frequency correlaions. In he empirical analysis below we aemp o idenify he impac of news direcly. 8 We define conracions as beginning when here are hree consecuive monhly declines in nonfarm payroll employmen, and ending when here are hree consecuive monhly increases in nonfarm payroll employmen. Conracions so-deermined mach closely hose designaed by he NBER over he poswar period. The conracion daes in our sample, moreover, remain unchanged if we adop an alernaive crierion of hree consecuive monhly declines in indusrial producion.

Andersen e al. / Journal of Inernaional Economics 73 (2007) 251 277 news, and hen we esimae responses of asse reurns o news, boh over he full sample and separaely for expansions and conracions. 3.1. Macroeconomic news We use he Inernaional Money Marke Services (MMS) real-ime daa on expeced and realized U.S. macroeconomic fundamenals, defining news as he difference beween he survey expecaions and he subsequenly announced realizaions. The MMS sample covers he period from January 1, 1992 hrough December 31, 2002. Table 4 provides a basic descripion of he announcemen releases, including he number of observaions, he agency reporing he news, and he ime of he release. 9 The unis of measuremen obviously differ across he macroeconomic indicaors. Hence, o allow for meaningful comparisons of he esimaed news response coefficiens across indicaors and asse classes, we follow Balduzzi, Elon, and Green (2001) and Andersen e al. (2003b) (2003) in he use of sandardized news. Specifically, we divide he surprise by is sample sandard deviaion, defining he sandardized news associaed wih indicaor k a ime as S k = (A k E k )/σˆ k, where A k denoes he announced value of indicaor k, E k refers o he marke's expecaion of indicaor k as disilled in he MMS median forecas, and σˆ k is equal o he sample sandard deviaion of he surprise componen, A k E k. Because σˆ k is consan for any indicaor k, his sandardizaion affecs neiher he saisical significance of he esimaed response coefficiens nor he fi of he regressions compared o he resuls based on he raw surprises. 3.2. Dynamic news effecs In order o analyze dynamic news effecs, we esimae response equaions using he wo fiveminue reurns direcly preceding and he eigheen five-minue reurns following each announcemen. 10 To allow explicily for cross-marke linkages and dynamic responses o news, we model he condiional mean of he five-minue reurn for asse h, R h, as a linear funcion of I lags of all reurns, ogeher wih J lags of each of he K news announcemens. (There are H = 9 differen asses.) Specifically, R h ¼ b h 0 þ XH i þ XK X J b h kj S k; j þ e h ; ¼ 1; N ; T; ð3:1þ where R h =log(p h /p h 1 ) denoes he five-minue fuures reurn corresponding o asse h (h=$/bp, $/Yen, $/Euro, S&P500, T-Bond, Gil, Bobl, FTSE, and DJE) from ime o ime +1, S k refers o he sandardized news for indicaor k (k=1,, 25) a ime, and he esimaes are based on only hose observaions (R h, S k ) where an announcemen was made a ime. Because he consumer credi, governmen budge, and federal funds rae figures are released inheafernoon,whenliffeandeurexareclosed,wehaveaoalofk =22 indicaors. 9 Wih he excepion of he money supply figures, which are released a 16:30 EST afer he fuures markes have closed, he indicaors lised in Table 4 include all regularly-scheduled major U.S. macroeconomic news announcemens. For a deailed descripion, including a discussion of he properies of he median expecaions, see Andersen e al. (2003b). 10 Hence he pos-announcemen window is one and one-half hours. Some preliminary experimenaion revealed ha our chosen pre- and pos-even windows were more han adequae o capure he sysemaic news responses.

Auhor's personal copy T.G. Andersen e al. / Journal of Inernaional Economics 73 (2007) 251 277 259 Guided by he Schwarz and Akaike informaion crieria, we uniformly fix he wo lag lenghs a I =2 and J =3, resuling in a oal of 107 regression coefficiens o be esimaed for each of he nine asses. We perform boh full-sample regressions and spli-sample regressions (expansion/ conracion, wih he full sample July 1, 1998 hrough December 31, 2002, and he expansion and conracion periods based on he observaions before and afer February 28, 2001, respecively. This leaves us wih a full sample of T = 15,764= 544 20 + 40 29 + 98 38 fiveminue reurn observaions, reflecing 544 days wih only one macroeconomic announcemen released on ha day (20 observaions per day), 40 days wih wo announcemens, one a 8:30 EST and he oher one a 9:15 EST (29 observaions per day), and 98 days wih wo announcemens, one a 8:30 EST and he oher a 10:00 EST (38 observaions per day). The expansion sample is comprised of he firs 9301 observaions, while he las 6463 observaions consiue he conracion sample. Alhough ordinary leas squares (OLS) would be consisen for he parameers in Eq. (3.1), he disurbance erms for he five-minue reurn regressions are clearly heeroskedasic. Thus, o enhance he efficiency of he coefficien esimaes, we use a wo-sep weighed leas squares (WLS) procedure. We firs esimae he condiional mean model by OLS. We hen use he absolue value of he regression residuals, εˆ h, o esimae a ime-varying volailiy funcion, which we hen subsequenly use o perform weighed leas squares esimaion of Eq. (3.1).

This is, of course, consisen wih basic heoreical predicions. I is noeworhy ha, almos invariably, only he simulaneous effec is significan, reflecing a very quick price discovery process.

This episode is well known o have increased credi spreads on risky securiies worldwide. The burs of uncerainy regarding he financial and economic healh of he inernaional economy is clearly refleced in our correlaion measures as hey ake on a paern oherwise only observed during he conracion. Our European series are somewha conaminaed by his even as hey only are observed from July, 1998 onward. Ignoring he immediae afermah of he financial crisis in lae 1998, he swich in he sign of he correlaions maches almos perfecly he previously exogenously imposed U.S. business cycle regime. Our analysis is, of course, limied o he relaively shor calendar ime span and single U.S. expansion conracion period covered by he high-frequency daa. 15 Noneheless, i is noeworhy ha even hough he German and Briish's business cycles do no necessarily coincide wih he U.S. business cycle, i appears as hough he relevan sae variable for deermining he ime-varying impac of he news announcemens is he sae of he U.S. economy raher han he foreign counry. 16 Indeed, he paerns in he ime-varying correlaions are enirely consisen wih our previous asserion ha he discoun rae effec dominaes in each of he hree sock markes during U.S. economic expansions, coupled wih he U.S. ineres rae playing he role of he world ineres rae and hence dicaing he move of he foreign bond markes. 17 4. A generalized specificaion We have argued ha he movemens in asse reurns across markes and counries documened above are driven by he common exposure o exogenous U.S. macroeconomic shocks and he U.S. business cycle. This conrass wih previous sudies ha also documen imporan spillover effecs and marke linkages, bu lile (if any) role for macroeconomic fundamenals in explaining he comovemens beween markes. Our posiive resuls can be aribued o our focus on synchronous high-frequency daa around he ime of he announcemen all asses are acively raded during announcemen imes, so we observe he immediae news reacion of all asses which miigaes oher influences and poenially imporan omied variables biases. To furher invesigae he exen of he cross-marke and cross-counry links in he highfrequency daa, beyond he direc influence of he macroeconomic news announcemen effecs, i is informaive o consider he simulaneous equaions model, R h ¼ b h 0 þ X h Vph ¼ 1; N ; T: h0 Rh V þ XH i þ XK X J b h kj S k; j þ g h ; ð4:1þ Excep for he inclusion of he conemporaneous asse reurns on he righ-hand side, he model is idenical o our basic model (3.1). As in Eq. (3.1), he β h k0 coefficiens direcly capure he U.S. h macroeconomic announcemen effecs, while he β h0 accoun for any conemporaneous crossasse linkages and/or spillover effecs ha are no explained by he news announcemens. This 15 Using daily dae over a much longer ime span, Connolly, Sivers and Sun (2005) find ha U.S. sock-bond reurn correlaions are inversely relaed o he level of aggregae sock marke volailiy as measured by he VIX index. The VIX may in urn be inerpreed as a sae variable relaed o he level of economic uncerainy and he sage of he business cycle in he sense of David and Veronesi (2004) and Ribeiro and Veronesi (2002). See also he recen relaed empirical resuls in Guidolin and Timmermann (2005, 2006). 16 The U.K. did no experience a conracion from March 2001 o December 2002. 17 The dominance of he U.S. ineress rae is consisen wih he recen empirical evidence repored in Chinn and Frankel (2004).

The problem from an economeric perspecive is ha, wihou any addiional resricions or modeling assumpions, he conemporaneous coefficiens in β h h0 are no idenified. To overcome his problem, we follow he approach of a recen series of papers by Rigobon (2003), Rigobon and Sack (2003a,b, 2004), and Senana and Fiorenini (2001), who use he condiional heeroskedasiciy in he high-frequency daa o idenify he conemporaneous response coefficiens. The idea is sraighforward. Assuming ha he innovaions in Eq. (4.1) are condiionally uncorrelaed bu heeroskedasic as indicaed by our previous esimaion resuls for Eq. (3.2) he condiional covariances of he implied (3.1) innovaions will hen move in proporion o he condiional heeroskedasiciy in he (4.1) innovaions, wih he facors of proporionaliy deermined by β h h0 This proporionaliy in urn, allows for he idenificaion and esimaion of he conemporaneous response coefficiens. 18 Our approach follows Rigobon and Sack (2003b), in esimaing he elemens of β h h0 by applying Gaussian quasi-maximum likelihood esimaion (QMLE) echniques o he mulivariae GARCH model implied by univariae GARCH models for each of he individual equaions in (4.1). 19 To faciliae he implemenaion of he mulivariae GARCH model, we rea he residuals from he firs-sage esimaion of (3.1) as direcly observable. Also, for racabiliy, we esimae he model for hree markes a a ime, bu he same idea could in principle be applied o any number of asses. Focusing firs on he rivariae domesic sysem consising of U.S. T-Bond, S&P500, and $/ Euro reurns, we obain he following esimaes for he conemporaneous linkages among he hree markes based on he 9301 five-minue announcemen period reurns spanning he July 1, 1998 hrough February 28, 2001 expansion ime period: R TBond R S&P R $=Euro ¼ 0:026R S&P ð 9:41Þ þ XK X J ¼ 0:204R TBond ð25:33þ þ XK X J ¼ 0:030R TBond ð12:53þ þ XK X J þ 0:020R $=Euro ð3:34þ b h kj S k; j þ g h þ 0:120R $=Euro ð14:88þ b h kj S k; j þ g h 0:002R S&P ð 2:39Þ b h kj S k; j þ g h ; þb h 0 þ XH þb h 0 þxh þb h 0 þ XH i i i ð4:2þ ð4:3þ ð4:4þ 18 Formally, consider he marix represenaion of (4.1), ΨR =ΦX 1 +η, where he η h are heeroskedasic bu serially and conemporaneously uncorrelaed. The corresponding (3.1) represenaion, R =Ψ 1 ΦX 1 +Ψ 1 η, hen uniquely deermines he disribuional properies of R. Imporanly, he non-zero off-diagonal elemens of he ime-varying condiional covariance marix for he (3.1) shocks, ε Ψ 1 η, depend direcly on Ψ 1, hus enabling idenificaion of Ψ. 19 To economize on he number of parameers, we include only hose macroeconomic news announcemen dummies ha were saisically significan a he five-percen level in he esimaion of Eq. (4.1). We also employ a more parsimonious GARCH(1,1) specificaion, E 1 ½ðg h Þ2 Šuðr h Þ2 ¼ x h þ b h ðr h 1 Þ2 þ k h ðg h 1 Þ2 þ P K g h;kd k;, as opposed o he ARCH (9) model implici in Eq. (4.1).

Andersen e al. / Journal of Inernaional Economics 73 (2007) 251 277 where he numbers in parenheses refer o robus -saisics. 20 A number of he coefficiens are highly significan and hey all have a naural inerpreaion. For example, an increase in sock prices may be seen as a signal of a posiive real aciviy or inflaionary shock and he poin esimae for he S&P500 reurn coefficien in Eq. (4.2) is enirely consisen wih he implicaions of he sylized moneary model. The impac of he exchange rae reurns is clearly less imporan, bu he sign is compaible wih exchange rae changes on balance reflecing real economic shocks. Eq. (4.3) is also direcly in line wih our aforemenioned discussion of he dominance of he discoun facor componen in he evaluaion of sock prices during economic expansions, whereby higher bond prices (lower discoun raes) are good for he sock marke in good imes. Similarly, dollar depreciaion (inerpreed as a negaive real aciviy or deflaionary shock) resuls in higher sock prices. Noice also ha while he uncondiional correlaion beween bond and sock prices for he expansion period repored in Table 3 is posiive, he esimaion mehod underlying Eqs. (4.2) (4.4) allows us o disenangle wo opposing effecs: bond prices affec sock prices posiively, bu sock prices affec bond prices negaively. 21 Finally, inerpreing negaive bond reurns and posiive sock reurns as indicaors of real economic srengh he associaed appreciaion of he Dollar implied by Eq. (4.4) is as expeced. Esimaing he same se of equaions for he 6463 five-minue announcemen period reurns over he March 1, 2001 hrough December 31, 2002 conracion ime period produces he following resuls: R TBond R S&P R $=Euro ¼ 0:033R S&P ð 6:26Þ þ XK X J ¼ 0:192R TBond ð 3:88Þ þ XK X J ¼ 0:033R TBond ð2:70þ þ XK X J þ 0:010R $=Euro ð0:47þ b h kj S k; j þ g h 0:090R $=Euro ð 1:97Þ b h kj S k; j þ g h 0:011R S&P ð 4:28Þ b h kj S k; j þ g h : þb h 0 þ XH þb h 0 þ XH þb h 0 þ XH i i i ð4:5þ ð4:6þ ð4:7þ The esimaes for Eqs. (4.5) and (4.7) are qualiaively as before, alhough he linkages among he ineres rae and he oher variables appear o have declined. This is consisen wih he ineres raes being less sensiive o economic shocks during he conracion. In conras, he difference in he esimaes for he S&P500 reurns in Eqs. (4.3) and (4.6) is sriking. The conemporaneous linkages beween he sock marke and he oher markes flips sign beween he wo periods. As 20 The repored -saisics do no formally accoun for he firs-sage condiional mean parameer esimaion error, bu his effec is almos surely negligible in he presen conex. 21 Our resuls for he high-frequency daa in Eqs. (4.2) and (4.3) agree wih he findings repored in Rigobon and Sack (2003b) based on daily sock and bond marke reurns from November 1985 o March 2001. Of course, his is predominanly an expansionary period, so i is no surprising ha he direcional effecs coincide.

Auhor's personal copy T.G. Andersen e al. / Journal of Inernaional Economics 73 (2007) 251 277 275 before, good news during expansions is bad news for socks, bu good news during conracions is good for he sock marke. In summary, he dominan finding is ha posiive sock reurns (posiive real or inflaionary shocks), ceeris paribus, always raise ineres raes, while posiive innovaions o ineres raes (real or inflaionary shocks) have a srongly regimedependen impac on sock reurns, once again confirming he differenial impacs of he cashflow and he discoun rae effecs over he business cycle. Finally, we use he same approach o esimae he inerdependence among he naional sock markes beyond he linkages explained by he U.S. macroeconomic announcemens. As before, dividing he sample in wo, we find for he expansion sample: R S&P R FTSE R DJE ¼ 0:028R FTSE ð5:83þ þ XK X J ¼ 0:014R S&P ð2:73þ þ XK X J ¼ 0:089R S&P ð13:26þ þ XK X J þ 0:007R DJE ð2:00þ b h kj S k; j þ g h þ 0:015R DJE ð9:57þ b h kj S k; j þ g h þ 0:001R FTSE ð0:23þ b h kj S k; j þ g h : þb h 0 þ XH þb h 0 þ XH þb h 0 þ XH i i i ð4:8þ ð4:9þ ð4:10þ No surprisingly, all esimaed coefficiens are posiive, indicaing imporan cross-counry linkages over-and-above hose explained by he U.S. macroeconomic news releases. I is unclear wheher hese high-frequency inernaional marke linkages are due o common reacions o worldwide fundamenal news or reflec cross-marke hedging or oher non-fundamenal conagion effecs. Esimaing he same relaions over he more recen conracion period suggess even sronger conemporaneous cross-counry linkages: R S&P R FTSE R DJE ¼ 0:447R FTSE ð17:80þ þ XK X J ¼ 0:074R S&P ð11:44þ þ XK X J ¼ 0:073R S&P ð10:49þ þ XK X J þ 0:210R DJE ð14:98þ b h kj S k; j þ g h þ 0:085R DJE ð9:88þ b h kj S k; j þ g h þ 0:115R FTSE ð8:74þ b h kj S k; j þ g h : þb h 0 þ XH þb h 0 þ XH þb h 0 þ XH i i i ð4:11þ ð4:12þ ð4:13þ
