intervention policy of the boj a unified approach intervening in the fx market implies a complex decision process for central banks monetary authorities have to decide whether to intervene or not and if so when and how since the successive steps of this procedure are likely to be highly interdependent we adopt a nested logit approach to capture their relationships and to characterize the prominent features of the various steps of the intervention decision process our estimations based on japanese data from 1991 to 2004 indicate that the bank of japan i mainly reacted to deviations of the exchange rate with respect to fundamentals and ii tended to favour secrecy when its credibility was low we also provide new insights on the so called secrecy puzzle by modeling explicitly the risk for a secret intervention to be detected our results have important implications in terms of exchange rate policy such as the emergence of a trade off between intervention size communication policy and secrecy our results tend to provide some explanation for the observed persistence of ineffective intervention policy during some sub periods c 2008 elsevier b v all rights reserved

central bank intervention and risk in the forward market abstract a two country inter temporal asset pricing model is developed which implies that central bank foreign exchange intervention affects the forward exchange risk premium the model is estimated from daily foreign exchange intervention data for the us german and japanese central banks considerable empirical support is found for the theoretical model with intervention influencing the risk premium in the forward market purchases of dollars by the federal reserve bank are found to be associated with excess denominated returns there is evidence that intervention has increased rather than reduced exchange rate volatility

official intervention in the foreign exchange market in an article in this journal dean taylor 1982 proposes a simple statistical test of the significance of central bank losses in the exchange market would random intervention be likely to result in as large a loss this comment shows that as it stands his test statistic does not allow properly for the effect of the mean level of intervention there is in fact an element of ambiguity in the question taylor poses and this is illustrated with examples taken from his empirical work the connection between the taylor test and regression analysis is noted and explored

fiscal policy outcomes and electoral accountability in american states clear fiscal policy effects appear in american state gubernatorial and legislative elections between 1968 and 1992 independent of the effects of incumbency coattails term limits and macroeconomic conditions the results show that accountability is generally stronger following a period of unified party control than under divided government voter reactions to taxes and spending relative to the state economy are conditional on expectations which differ for each party net of these expectations republican gubernatorial candidates lose votes if their party is responsible for unanticipated increases in the size of the state budget democrats do not and indeed may be rewarded for small increases independent of this the incumbent governor s party is punished in legislative elections for failing to maintain fiscal balance taken together these results show how electoral accountability for fiscal policy outcomes is strong but highly contingent on a complex configuration of party labels partisan control expectations and institutions

the great intervention and massive money injection the japanese experience 2003 2004 abstract from the beginning of 2003 to the spring of 2004 japan s monetary authorities conducted large scale yen selling dollar buying operations in what taylor 2006 has labeled the great intervention this paper examines the relationship between this great intervention and the quantitative easing policy the bank of japan was pursuing at that time first we find that about 40 percent of the yen funds supplied to the market by yen selling interventions were not offset by the boj s monetary operations and remained in the market for a while this is in contrast with the preceding period when almost 100 percent were immediately offset second comparing interventions and other government payments the extent to which the funds were offset was much smaller in the case of interventions suggesting that the boj differentiated between and responded differently to interventions and other government payments these two findings indicate that it is likely that the boj intentionally did not sterilize yen selling interventions to achieve its policy target of maintaining the current account balances of commercial banks at the boj at a high level finally we find that an unsterilized intervention had a greater impact on the yen dollar rate than a sterilized one suggesting that it matters whether an intervention is sterilized or not even when the economy is in a liquidity trap

guns and butter and government popularity in britain britain under the government of prime minister thatcher provides a unique opportunity to probe the effects of both war and macroeconomic performance on government popularity monthly ratings for thatcher and conservative party support june 1979 to july 1985 are examined by way of box tiao intervention models the model that best captures the impact of the falklands war of 1982 is of the gradual temporary variety popularity gains accrued through the three month war shrink in a geometric fashion nevertheless they prove to be worth over five percentage points for the conservative party a year later in the 1983 election macroeconomic performance meanwhile is found to have an asymmetric effect on government popularity with unemployment strongly significant but inflation not significant at all apparently the british public is punishing failure on employment while letting success on inflation go unrewarded qualifications of the positive effect of war and the negative effect of macroeconomic performance are suggested

relationships among exchange rates intervention and interest rates an empirical investigation abstract this study uses herefore unavailable daily data on official intervention to test the joint hypotheses of perfect asset substitutability and exchange market efficiency this joint hypothesis is generally soundly rejected for six exchange rates over various sample periods in contrast to evidence elsewhere from weekly or monthly data lagged intervention is a significant determinant of realized profits in about half the cases this evidence is consistent with existence of a portfolio balance channel at least in the short run other evidence indicates that coordinated intervention sometimes may have an impact significantly different from intervention by one central bank alone

international spillovers of large scale asset purchases this paper evaluates the international spillover eects of large scale asset purchases lsaps using a two country dynamic stochastic general equilibrium model with nominal and real rigidities and portfolio balance eects portfolio balance eects arise from imperfect substitution between short and long term bond portfolios in each country as well as between domestic and foreign bonds within these portfolios we show that lsaps lower both domestic and foreign long term yields and stimulate economic activity in both countries international spillover eects

in search of the exchange risk premium a six currency test assuming mean variance optimization abstract a number of authors examining deviations of actual rates of currency depreciation from forward discounts have claimed to find evidence of risk premiums if these deviations are indeed partly due to risk premiums rather than being entirely due to expectational errors then they should be systematically related to those variables on which risk premiums are thought to depend finance theory tells us that if investors optimize with respect to mean and variance the risk premium depends in a specific way on 1 the supplies of assets denominated in the various currencies 2 the variance covariance matrix of the rates of return and 3 the coefficient of risk aversion the null hypothesis of this paper is that the coefficient of risk aversion is zero countries assets are perfect substitutes and risk premiums are nonexistent the alternative hypothesis is that rates of return are systematically related to asset supplies by a macroeconomic portfolio balance function the maximum likelihood technique used dominates previous attempts to find such a relationship in that the parameters of the portfolio balance function are constrained to depend on the variance covariance matrix as the finance theory says they should on the other hand the technique also dominates previous applications of the finance theory in that the expected returns are allowed to vary over time as the macroeconomic portfolio balance theory says they should the paper s finding is a statistical inability to reject the null hypothesis for a portfolio of six currencies although this could be due to low power in the test

a portfolio balance rational expectations model of the dollar mark exchange rate abstract a model is developed in which current account imbalances can be financed through transfers of bonds denominated in either currency the reduced form links the current spot rate to the expected future spot rate via a risk premium which depends on the global currency mix of outside assets that governments impose on private portfolios through budget deficits and interventions and on the global distribution of private wealth among regions with different portfolio preferences an iterative procedure generates rational expectations forecasts of the dollar mark rate which perform somewhat better than forward rates in predicting monthly changes in the spot rate

accounting for reserves abstract views on the effectiveness of sterilized reserve intervention vary sterilized intervention is generally seen as ineffective in advanced countries while persistent intervention by some emerging markets is often cited as contributing to undervalued exchange rates and current account surpluses this paper argues that capital controls reconcile these views we find strong and highly robust evidence that sterilized intervention is fully offset by outflows of private money in countries without controls while controls partially block this offset for a country with extensive capital controls every dollar in additional reserves increases the current account by some 50 100 cents this is mainly offset by an opposite adjustment in the current account of the united states the dominant reserve currency issuer with the deepest and most liquid bond markets with a smaller diversion to emerging markets

identifying the efficacy of central bank interventions evidence from australia and japan abstract using a model incorporating the endogenous relationship between exchange rates and intervention we show how a change in central bank policy can be used as an identification assumption estimating this model with simulated gmm for daily data from australia and japan we find that a us 100 million purchase appreciates the australian dollar by 1 3 1 8 but the yen by just 0 2 almost all of the impact of an intervention occurs during the day it is conducted and we confirm that central banks typically lean against the wind

capital controls on inflows exchange rate volatility and external vulnerability abstract we use high frequency data and a new econometric approach to evaluate the effectiveness of controls on capital inflows we focus on chile s experience during the 1990s and investigate whether controls on capital inflows reduced chile s vulnerability to external shocks we recognize that changes in the controls will affect the way in which different macro variables relate to each other in particular we consider the case where controls co exist with an exchange rate band aimed at managing the nominal exchange rate we develop a methodology to deal explicitly with the interaction between these two policies the main findings may be summarized as follows a a tightening of capital controls on inflows depreciates the exchange rate and b we find that a tightening of capital controls increases the unconditional volatility of the exchange rate but makes it less sensitive to external shocks

the determinants of foreign exchange intervention by central banks evidence from australia abstract intervention by the reserve bank of australia on foreign exchange markets from 1983 to 1997 is conjectured to have been determined by exchange rate trend correction exchange rate volatility smoothing the us and australian overnight interest rate differentials profitability and foreign currency reserve inventory considerations using probit and friction models we show that these factors were significant influences on intervention behavior consistent with the constraint of intervening only when a clear trend is apparent we find that above average measures of deviations from trend and of volatility muted the response of the reserve bank

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

central bank authorities beliefs about foreign exchange intervention abstract this paper presents the results of a survey of monetary authorities with respect to foreign exchange intervention the survey offers evidence on new issues that would otherwise be difficult to investigate such as response times non foreign exchange factors in intervention and profitability the survey also reveals new evidence on previously studied issues such as channels of effectiveness respondents disagreed with predominant views on intervention and volatility and common arguments against intervention exchange rate regimes explain central bank beliefs about important aspects of intervention including factors that lead to detection of secret interventions and the potential profitability of intervention

what prompts japan to intervene in the forex market a new approach to a reaction function abstract this paper estimates and analyzes the reaction function of japanese intervention in the foreign exchange forex markets using daily japanese intervention data from april 1 1991 to december 31 2002 a theoretical friction model is adopted to describe the intervention as cost minimizing behavior an ordered probit model consistent with the theoretical model is employed to estimate authorities reaction function a noise to signal ratio is applied in selecting the optimal cutoff point in estimated ordered probit function major findings are as follows 1 a regime change in june 1995 from small scale frequent interventions to large scale infrequent interventions is detected 2 the optimum cutoff is higher in the first half than the second half

foreign exchange market intervention in two small open economies the canadian and australian experience abstract we examine intervention by the bank of canada and the reserve bank of australia for daily data from 1989 to 1998 both central banks intervene in response to excessive exchange rate volatility and uncertainty volatility is the implied volatility of foreign currency futures options uncertainty is the kurtosis of the implied risk neutral probability density functions we also examine the impact of inflation targets unlike other studies we also consider commodity futures prices these turn out to help explain the effectiveness of intervention central bank intervention was largely unsuccessful in both countries though volatility and kurtosis were modestly affected

a new method for identifying the effects of foreign exchange interventions central banks react even to intraday changes in the exchange rate however in most cases intervention data is available only at a daily frequency this temporal aggregation makes it difficult to identify the effects of interventions on the exchange rate we apply the bayesian mcmc approach to this endogeneity problem we use data augmentation to obtain intraday intervention amounts and estimate the efficacy of interventions using the augmented data applying this new method to japanese data we find that an intervention of one trillion yen moves the yen dollar rate by 1 7 percent which is more than twice as much as the magnitude reported in previous studies applying ols to daily observations this shows the quantitative importance of the endogeneity problem due to temporal aggregation

the vp function a survey of the literature on vote and popularity functions after 25 years vp functions explain the support for the government at votes and polls by economic and political variables most studies analyze macro time series we also cover studies of individual voters socio economic groups and regional cross sections the theory starts from the responsibil ity hypothesis voters hold the government responsible for economic conditions it works in two party block systems but not else voters in most countries are found to be sociotropic egotropic voting also occurs voters myopia is well established voting is retrospective as expectations are static it costs the average government almost 2 of the vote to rule

real time effects of central bank interventions in the euro market abstract this paper investigates the real time effects of sterilized foreign exchange intervention using official intraday intervention data provided by the danish central bank our analysis employs a two step weighted least squares estimation procedure we control for macro surprises address the issue of endogeneity and carry out an array of robustness tests only when the direction of intervention is consistent with the monetary policy stance do we find that intervention exerts a significant influence on exchange rate returns

the time variation of risk and return in the foreign exchange and stock markets this paper attempts to determine whether the fluctuations of conditional first and second moments which are observed for many assets are consistent with the sharpelintner mossin capital asset pricing model we test the mean variance model under several different assumptions about the time variation of conditional second moments of returns using weekly data from july 1974 to december 1986 that include returns on a portfolio composed of dollar deutsche mark sterling and swiss franc assets together with the u s stock market the results indicate that estimated conditional variances cannot explain the observed time variation of risk premia rates of return on international financial assets are characterized by statistical properties that are quite common to all financial markets they are highly volatile and largely unpredictable these properties make it very difficult to extract statistically reliable estimates of systematic exchange rate and assetprice movements and are at the root of the generally poor empirical performance of international asset pricing models nevertheless two important results have been uncovered by empirical researchers and can be considered a fair characterization of the data a expected returns on foreign assets vary over time cumby and obstfeld 1981 and the numerous articles that followed recently surveyed by frankel and meese 1987 b the volatility of returns of foreign assets also changes over time cumby and obstfeld 1984 hodrick and srivastava 1984 and hsieh 1988 among others as giovannini and jorion 1987 suggest the

the effectiveness of central bank intervention in the ems the post 1993 experience abstract we analyze the effectiveness of intervention in the european monetary system by using data on the dem intervention activity of six european central banks covering the period from august 1993 to april 1998 to allow for regime specific intervention effects we estimate markov switching autoregressive conditional heteroscedasticity models we find that interventions have only limited effects on the conditional means and variances

tests of international capm with time varying covariances we perform maximum likelihood estimation of a model of international asset pricing based on capm we test the restrictions imposed by capm against a more general asset pricing model the betas in our capm vary over time as the supplies of assets change and as the conditional covariances or returns on those assets change we let the covariances change over time as a function of macroeconomic data and an alternative model allows the covariances to follow a multivariate arch process we also can identify a modified capm model with measurement error we find that the estimated capm performs much better when variances are not constant over time nonetheless capm is rejected in favour of the lessrestricted model of asset pricing

a friction model of daily bundesbank and federal reserve intervention abstract this paper takes a novel approach to derive a central bank intervention reaction function a garch model for exchange rates is amended to allow interventions to have an effect on both the mean and the variance of exchange rate returns an intervention reaction function is obtained by combining the model with a loss function for the central bank estimation results for the implied friction model reproduce the familiar leaning against the wind policy by the bundesbank and the federal reserve furthermore the central banks appear to have reacted to increases in the conditional variance of daily dm returns

on the long term effectiveness of exchange rate communication and interventions abstract exchange rate communication has come to play an increasingly important role as a policy tool for monetary authorities over the past decade the paper assesses the strategies and the long term effectiveness of communication as well as actual interventions the empirical results for the g3 economies indicate that communication has not only exhibited a significant contemporaneous effect on exchange rates but also has moved forward exchange rates up to a horizon of 6 months in the desired direction moreover communication is found to reduce exchange rate volatility and uncertainty whereas actual interventions tend to raise it overall this underlines a key difference between these two policy tools and suggests that communication tends to be a fairly effective policy tool over the medium term

central bank communication and monetary policy a survey of theory and evidence over the last two decades communication has become an increasingly important aspect of monetary policy these real world developments have spawned a huge new scholarly literature on central bank communication mostly empirical and almost all of it written in this decade we survey this ever growing literature the evidence suggests that communication can be an important and powerful part of the central bank s toolkit since it has the ability to move financial markets to enhance the predictability of monetary policy decisions and potentially to help achieve central banks macroeconomic objectives however the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy

intraday effects of foreign exchange intervention by the bank of japan abstract we examine the effects of intervention by the bank of japan using intraday data from oct 1 1992 to sept 30 1993 news related to the bank of japan s intervention in the jpy market was retrieved from reuters headlines we find that jpy volatility varies significantly differently across periods from 1 h before to 1 h after reuters intervention reports results from arch models show that intervention by the bank of japan has a positive and significant impact on jpy volatility particularly at high frequencies 5 and 10 min intervals we also find that our intervention proxy has the largest effect upon high frequency volatility 30 to 45 min prior to reuters reports

the advantage to hiding one s hand speculation and central bank intervention in the foreign exchange market abstract we analyze an asymmetric information model of sterilized intervention in the foreign exchange market we characterize an equilibrium in which a central bank with inside information about its exchange rate target trades with risk averse speculators who have private information about future spot rates the model identifies circumstances in which perverse responses to intervention will be observed i e the domestic currency depreciates when the central bank purchases it and it provides conditions under which the exchange rate will be highly sensitive to intervention the model also provides an explanation for two forms of policy secrecy i secrecy about the scale of an intervention operation is always desirable ii secrecy about the target is sometimes desirable

why do central banks intervene abstract intervention by central banks in terms of buying and selling foreign currency has been a major activity in recent years this paper investigates the motivations for such policy and the evidence for its effectiveness we use high quality daily data on the dollar amounts of intervention by the central banks of the us and germany we also use information on agreed g7 target levels for the dm and yen nominal exchange rates daily nominal dollar exchange rate returns are well described as a martingale garch process and we find little evidence that the different types of intervention have had much effect on the conditional mean of exchange rate returns there is some evidence that intervention is associated with slight increases in the volatility of exchange rate returns while little evidence is found for the effectiveness of intervention the motivations are more clear in particular from the application of probit analysis we find that the probability of intervention is determined by the magnitude of the deviation of the nominal exchange rate from the agreed target level and to a lesser extent by the current volatility of exchange rates

foreign exchange market interventions and the exchange rate in the long run this article examines whether foreign exchange market interventions conducted by the bank of japan are important for the dollar yen exchange rate in the long run we rely on a re examination of the empirical performance of a monetary exchange rate model this is basically not a new topic however we focus on two new questions first does the consideration of periods of massive interventions in the foreign exchange market uncover a potential long run relationship between the exchange rate and its fundamentals second do forex interventions support the adjustment towards a long run equilibrium value our results suggest that taking periods of interventions into account within a monetary model does improve the goodness of fit of an identified long run relationship to a significant degree furthermore forex interventions increase the speed of adjustment towards long run equilibrium in some periods particularly in periods of coordinated forex interventions our results indicate that only coordinated inter

information sharing and central bank intervention in the foreign exchange market abstract this paper develops a model of information sharing among heterogeneously informed agents and it uses the model to examine a rationale for intervention in the foreign exchange market the model shows that in a partially revealing rational expectations equilibrium some agents can gain by sharing among themselves private information about transitory exchange rate disturbances in this setting a central bank can affect the exchange rate by aggregating and disseminating agents information the paper also illustrates the usefulness of intervention as a way to transmit that information

large versus small foreign exchange interventions abstract we use non temporal threshold analysis to investigate the exchange rate effects of large versus small interventions more than two decades of official daily data on intervention in the jpy usd market facilitate our analysis we find no evidence that small interventions exert a discernible influence on the exchange rate while large interventions significantly influence the exchange rate in the theoretically consistent manner we conclude that small interventions may not be considered a determinant of the exchange rate while large interventions constitute an important element in our understanding and modeling of the exchange rate

exchange rate manipulation and constructive ambiguity i consider dynamic models in which investors are heterogeneously informed about both foreign exchange interventions and exchange rate fundamentals and show that transparency sometimes exacerbates misalignment between the exchange rate and fundamentals although transparency reveals information about fundamentals it also increases the precision of the exchange rate as a signal of those fundamentals that remain unknown the signal precision effect of transparency if a central bank announcement reveals little information about fundamentals then this effect dominates and transparency magnifies misalignment one implication is that ambiguity can increase the effectiveness of intervention to support a declining currency during times of crisis

central banks and macroeconomic policy choices relaxing the trilemma abstract macroeconomic policy choices in open economies are constrained by the trilemma according to which the objectives of exchange rate stability monetary independence and capital mobility cannot be attained jointly this paper shows that foreign exchange interventions provide an effective instrument to relax the trilemma an active reserve policy allows central banks to pursue independent monetary and exchange rate policies when the capital account is liberalised we use the framework of the portfolio balance model to show that exchange market interventions may substitute for capital controls both allow a country to achieve the other two objectives of the trilemma our empirical analysis of a large country panel data set covering the period 1970 2010 confirms this theoretical insight the weighted sum of the three trilemma objectives increases in the degree of foreign exchange market intervention the capacity to relax the trilemma constraint has increased over time and has been most effective in emerging markets

budgetary and producer welfare effects of revenue insurance legislation passed in 1996 changed the way the u s federal government acts to reduce risks faced by u s crop products the authors compare the new alternative forms of revenue insurance to the 1990 deficiency payment program and to a no program alternative they estimate the effects of the alternative polices on the acreage allocations of a representative farm on the expected government cost and on producer welfare simulation results indicate that a revenue insurance scheme that guarantees 75 percent of expected revenue to risk averse produced could provide approximately the same level of benefits as the 1990 program at as little as one fourth the cost

peasants or bankers the american electorate and the u s economy t he usual model of electoral reaction to economic conditions assumes the retrospective economic voter who bases expectations solely on recent economic performance or personal economic experience voter as peasant a second model assumes a sophisticated economic voter who incorporates new information about the future into personal economic expectations voter as banker using the components both retrospective and prospective of the index of consumer sentiment ics as intervening variables between economic conditions and approval we find that the prospective component fully accounts for the presidential approval time series with aggregate consumer expectations about long term business conditions in the approval equation neither the usual economic indicators not the other ics components matter moreover short term changes in consumer expectations respond more to current forecasts than to the current economy the qualitative result is a rational expectations outcome the electorate anticipates the economic future and rewards or punishes the president for economic events before they happen economics moves political behavior with hard times administrations lose support with good times they gain it we know this to be true but when we ask how by what processes the political translation of economic experience occurs the an

the impact of fx central bank intervention in a noise trading framework abstract in this paper we analyse the effectiveness of the direct central bank interventions using a new effectiveness criterion to this aim we investigate the effects of central bank interventions cbi in a noise trading model with chartists and fundamentalists we first estimate a model in which chartists extrapolate past returns and fundamentalists forecast a mean reverting dynamics of the exchange rate towards a fundamental value then we investigate the role of central bank interventions for explaining the switching properties between the two types of agents we find evidence that in the medium run interventions increase the proportion of fundamentalists and therefore exert some stabilizing influence on the exchange rate

the dynamics of public support for coalition governments this article investigates the relationship between economic conditions and party support for coalition parties in denmark and the netherlands the article argues that the simple reward punishment model cannot fully account for changes in citizens support for parties given variable economic performance using aggregate public support data for political parties the article shows that citizens differentiate between coalition partners depending on the parties issue priorities instead of blaming or rewarding all coalition parties in a uniform fashion citizens shift support from one coalition party to another depending on the perceived competence of a party to deal with particular economic problems the article finds that the structure of responsibility in parliamentary democracies ruled by coalition governments is more complex than is often assumed therefore it is argued that students of economics and public opinion should pay particular attention to the institutional context in which citizens make ch

the effects of party competition on budget outcomes empirical evidence from local governments in spain this paper investigates the link between local budget outcomes and the intensity of party competition measured as the margin of victory obtained by the incumbent in the previous local election i e the difference between the vote share and 50 two competing hypotheses are tested in the paper on the one hand the leviathan government hypothesis suggests that the lower the intensity of party competition is the greater is the increase in the size of the local public sector irrespective of the ideology of the party in power on the other hand the partisan government hypothesis suggests that the incumbent will find it easier to advance its platform when intensity of competition is low i e parties on the left right will increase decrease the size of the local public sector when the intensity of the challenge from the opposition is low these hypotheses are tested with information on spending own revenues and deficit for more than 500 spanish local governments over 8 years 1992 1999 and information on the results of two local electoral contests 1991 and 1995 the evidence favors the partisan hypothesis over the leviathan one we found that for left wing governments spending taxes and deficits increased as the electoral margin increases whereas for right wing governments a greater margin of victory led to reductions in all these variables

occasional interventions to target rates this paper develops a model of central bank intervention based upon a policy characteristic of foreign exchange interventions by the united states germany and japan in the late 1980 s and evaluates it empirically central bankers intervene with greater intensity as rates deviate from target levels but they also try to stabilize rates around current levels the model is estimated using exchange rates and data based upon observed central bank interventions interestingly the estimates of the model are consistent with the predictions of the theoretical model for both the deutsche mark dollar rate and less strongly for the yen dollar rate jel f41 g15 f31

are foreign exchange forecasts rational new evidence from survey data abstract tests of rationality in foreign exchange markets have been inconclusive because of disagreement over the relevant asset pricing model this paper uses a newly available set of data on foreign exchange expectations to directly test the rationality of four foreign currency markets overall the results reject the rational expectations hypothesis

oral interventions versus actual interventions in fx markets an event study approach the article assesses whether exchange rate communication or oral intervention has been an effective policy tool for monetary authorities to influence exchange rates it employs an event study methodology that identifies intervention clusters or events for the euro dollar and the dollar yen exchange rates the article finds that both oral intervention events and actual intervention events have been highly successful over the short to medium run the article shows that the success of intervention events is related to market conditions and to the coordination among policy makers it also finds that the success of communication and actual interventions is largely unrelated to monetary policy thus suggesting that interventions primarily function through a coordination channel

central bank forex internvention assessed in continous time abstract this paper looks at some of the principal characteristics of foreign exchange intervention by central banks the approach is novel in that virtually continous time data have been exploited using reuters screen information jel f31

a test of perfect substitutability in the foreign exchange market i motivations for the test the question of whether or not domestic bonds are perfect substitutes for foreign bonds in investors portfolios implying that the expected rates of returns must be equalized across currencies is an important one for two reasons the question is crucial first for choosing among various asset market models of exchange rate determination and second for evaluating tests of efficiency in the forward exchange market to illuminate the first motivation a brief discussion of models of exchange rate determination is necessary all asset market models share the assumption that there are no significant transactions costs capital controls or other impediments to the international flow of capital thus actual portfolios adjust instantaneously to equal desired portfolios this implies for example covered interest parity the domestic interest rate should differ from the foreign interest rate by an amount exactly equal to the forward discount rate perfect substitutability between domestic and foreign bonds is the stronger assumption that market participants are indifferent as to the currency composition of their portfolio it implies uncovered interest parity the domestic interest rate must differ from the foreign interest rate by an amount exactly equal to the expected rate of depreciation the perfect substitutability assumption is far from standard in fact exchange rate models within the asset market view can be classified into those that belong to the monetary approach defined by the assumption of perfect substitutability and those that belong to the portfolio balance approach defined by the assumption of imperfect substitutability in the portfolio balance approach investors hold well defined proportions of their wealth in the form of each country s assets with the proportions depending on the expected rates of return as in equation 1

a new approach to the effect of intervention frequency on the foreign exchange market evidence from japan this article estimates and analyses the effect of intervention frequency on the yen dollar market using daily intervention data we examine using a nonlinear methodology with the frequency of intervention from april 1991 to december 2005 as a focal explanatory variable in this article we also introduce a flexible target zone model that is capable of characterizing the dynamic behaviour of an exchange rate implied by the original target zone model of krugman and its modifications the empirical results show the importance of considering the threshold effect when analysing the effect of intervention due to the presence of asymmetry in the foreign exchange market moreover we show that a high frequency intervention stabilizes the exchange rate by reducing exchange rate volatility especially when the yen appreciates

the market microstructure of central bank intervention abstract how quickly do central bank intervention operations impact the foreign exchange market and do intra daily market conditions influence the effectiveness of central bank interventions this paper uses high frequency intra daily data to examine the relationship between the efficacy of intervention operations and the state of the market at the moment that the operation is made public the results indicate that some traders typically know that the fed is intervening at least 1 h prior to the public release of the information in newswire reports also the evidence suggests that the timing of intervention operations matters interventions that occur during heavy trading volume that are closely timed to scheduled macro announcements and that are coordinated with another central bank are the most likely to have large effects

central bank intervention and exchange rate volatility abstract this paper explores the effects of foreign exchange intervention by central banks on the behavior of exchange rates the g 3 central banks have undertaken an unprecedented number of both coordinated and unilateral intervention operations in the last 10 years existing empirical evidence on the effectiveness of intervention is mixed studies using data from the 1970s suggest that intervention operations that do not affect the monetary base have at most a short lived influence on exchange rates but more recent studies indicate that the intervention operations that followed the plaza agreement influenced both the level and variance of exchange rates this paper examines the effects of us german and japanese monetary and intervention policies on dollar mark and dollar yen exchange rate volatility over the 1977 1994 period the results indicate that intervention operations generally increase exchange rate volatility this is particularly true of secret interventions which are those undertaken by central banks without notification of the public overt interventions in the mid 1980s appear to have reduced exchange rate volatility but in other periods and for the 1977 1994 period as a whole central bank intervention is associated with greater exchange rate volatility

designing optimal crop revenue insurance when the indemnity schedule is contingent on the farmer s price and individual yield an optimal crop revenue insurance contract depends only on the farmer s gross revenue however this design is not efficient if as is the case with available contracts the coverage function is based on imperfect estimators of individual yield and or price the producer s degree of prudence and the extent of basis risks have important influences on the optimal indemnity schedule in this broader context optimal protection is not provided by available u s crop insurance contracts and may include combinations of revenue insurance yield insurance futures and options contracts

on the effects of sterilized intervention an analysis of weekly data abstract as the recent empirical studies surveyed here illustrate it is very difficult to demonstrate that the exchange rate risk premium depends through a portfolio balance channel on the currency composition of outside assets the existence of a portfolio balance effect is a necessary condition for sterilized intervention to be a genuinely independent tool of monetary policy this paper studies u s canadian data and attempts to improve on earlier studies by using higher frequency weekly data and by implementing an appropriate instrumental variables technique 2s2sls however we still fail to detect evidence of a portfolio balance effect

does foreign exchange intervention matter the portfolio effect until recently there was an unusual degree of consensus among economists that intervention by central banks in the foreign exchange market did not offer an effective or lasting instrument for affecting the exchange rate at least not independently of monetary policy this consensus was largely shared among policymakers and participants in the financial markets as well the 1982 g 7 economic summit at versailles commissioned a study of intervention known as the jurgenson report which found that the effects were small and transitory at most we think that the time is ripe for new statistical testing of the question many policymakers and foreign exchange traders believe that the intervention operations that have taken place since the plaza agreement of september 1985 have had an effect especially when operations are coordinated moreover the theoretical case against the effectiveness of intervention is not as clear as a reading of the economics literature might suggest the academic literature is predicated on the distinction between intervention operations that are sterilized and those that are allowed to affect the money supply we study the intervention operations that actually took place between 1982 and 1988 regardless of whether they were sterilized however we do begin in section i with a review of the issues involved 2 there are two possible channels through which intervention whether sterilized or not can influence the foreign exchange rate the portfolio and the expectations channels intervention can even if sterilized influence exchange rates through the portfolio channel provided foreign and domestic bonds are considered imperfect substitutes in investors portfolios intervention operations that for example increase the current relative supply of mark to dollar assets which private investors are obliged to accept into their portfolios will force a decrease in the relative price of mark assets 3 intervention can also influence exchange rates regardless of whether foreign and domestic bonds are imperfect substitutes through the expectations channel the public information that central banks are intervening in support of a currency or are planning to intervene in the future may under certain conditions cause speculators to expect an increase in the price of that currency in the future speculators react to this information by buying the currency today bringing about the change in the exchange rate today in sections ii and iii we describe the econometric problems that arise in the standard portfolio balance estimation equation we derive an alternative portfolio balance dominguez kennedy school of government harvard university 79 j f kennedy street cambridge ma 02138 frankel department of economics university of california 787 evans hall berkeley ca 94720 we thank three anonymous referees for valuable comments and suggestions julia marsh and julia lowell for research assistance and franz scholl at the bundesbank jean pierre roth at the swiss national bank and officials at the u s treasury and the board of governors of the federal reserve system for making the daily intervention data available 1many of the econometric results finding little or no effect were reported in kenneth s rogoff 1984 and dale w henderson and stephanie sampson 1983 2for authoritative statements see henderson 1984 or maurice obstfeld 1990 3the exchange rate reaction to an increase in the relative supply of outside foreign assets may be reduced if there is an increase in their expected rate of return that induces a corresponding increase in demand

channels of us monetary policy spillovers to international bond markets abstract we show significant us monetary policy mp spillovers to international bond markets our methodology identifies us mp shocks as the change in short term treasury yields around federal open market committee meetings and traces their effects on international bond yields using panel regressions we emphasize three main results first us mp spillovers to long term yields have increased substantially after the 2007 2009 global financial crisis second spillovers are large compared with the effects of other events and at least as large as the effects of domestic mp after 2008 third spillovers work through different channels concentrated in risk neutral rates expectations of future mp rates for developed countries but predominantly on term premia in emerging markets in interpreting these findings we provide evidence consistent with an exchange rate channel according to which foreign central banks face a trade off between narrowing mp rate differentials or experiencing currency movements against the us dollar developed countries adjust in a manner consistent with freely floating regimes responding partially with risk neutral rates and partially through currency adjustments instead emerging countries display patterns consistent with foreign exchange interventions which cushion the response of exchange rates but reinforce capital flows and their effects in bond yields through movements in term premia our results suggest that the endogenous effects of currency interventions on long term yields should be added into the standard cost benefit analysis of such policies

the pricing of revenue assurance a theoretical model to value gross revenue assurance under one of the popular proposals facing u s policy makers is developed the approach makes use of a fundamental paradigm of asset valuation and stochastic calculus because farm level gross revenue is not a traded asset equilibrium arguments must be made to specify the partial differential equation characterizing the value of the assurance an example solution is presented under the assumption of lognormally distributed gross revenue county level data for a variety of crops are used to examine empirically the pricing ability of the model

fed intervention dollar appreciation and systematic risk abstract in a four factor asset pricing model estimated on daily data fed intervention significantly affects betas of surprises in the market return expected inflation rate yield curve and corporate bond risk premium fed foreign currency sales cause economically and statistically significant increases in the systematic risk premium in appreciation and thus in the dollar s expected appreciation rate the direction the fed desires and consistent with the signaling but not the portfolio balance channel intervention s effects on actual appreciation are less reliable they depend on unpredictable risk factor realizations even successful intervention to strengthen the dollar may be costly by increasing the dollar s systematic risk intervention reduces the attractiveness of u s relative to foreign investments further uncertainty about future fed interventions may induce resource misallocation ceteris paribus investors find it harder to estimate risk adjusted discount rates and forecast the home currency value of cash flows

a class of quadratic options for exchange rate stabilization abstract we propose the use of a new option which we call quadratic and that central banks could use to smooth exchange rate volatility through the hedging strategies of the issuers we derive analytic pricing and hedging formulas we suggest a criterion to derive the optimal for the central bank option parameters finally we perform several simulation exercises which show the effectiveness of using this option with or without conventional spot interventions

evaluating foreign exchange market intervention self selection counterfactuals and average treatment effects abstract estimating the effect of official foreign exchange market intervention is complicated by the fact that intervention at any point entails a self selection choice made by the authorities and that no counterfactual is observed to address these issues we estimate the counterfactual exchange rate movement in the absence of intervention by introducing the method of propensity score matching to estimate the average treatment effect ate of intervention to derive the propensity scores we estimate central bank intervention reaction functions we estimate the ate for daily official intervention in japan over the january 1999 march 2004 period this sample encompasses a remarkable variation in intervention frequencies as well as unprecedented frequent intervention towards the latter part of the period we find that only sporadic and relatively infrequent intervention is effective

on the theory of international currency portfolios abstract the paper develops a general equilibrium theory of the optimal currency composition of international bond portfolios like the partial equilibrium portfolio balance literature of the 1980s the theory emphasizes the critical roles of government debt and government balance sheet operations in the determination of portfolios prices and allocations consistent with empirical findings optimal foreign currency positions are found to be small with their size decreasing with exchange rate volatility while optimal domestic currency positions are large and increasing with domestic interest rates a large open market purchase of domestic currency bonds from private households lowers domestic interest rates

exchange rate effects of central bank interventions an analysis of transaction prices the impact of sterilised interventions by the swiss national bank on the swiss franc u s dollar exchange rate is examined for the 1986 94 period the paper extends results from earlier studies by using the actual prices of interventions based on the fact that all swiss national bank interventions are announced our test exploits the informational differences between interventions and customer transactions a key finding is that only initial interventions matter customer transactions and subsequent interventions have no influence when the bretton woods system of fixed exchange rates broke up in the early 1970s central banks continued to intervene on the foreign exchange market in the meantime a substantial literature has emerged that focuses on the effectiveness of official interventions this literature has been summarised by edison 1993 and almekinders 1995 chapter 3 its central policy issue is whether sterilised interventions defined as interventions that leave the monetary base unchanged can have a significant influence on exchange rate behaviour macroeconomic theory proposes various channels for interventions to operate through but the empirical evidence accumulated over the years is less encouraging it suggests that there is no permanent effect of sterilised interventions on the exchange rate more surprisingly perhaps even shortterm effects are hard to pin down the evidence is weak and sample dependent at best in most cases coefficients are either insignificant or have the wrong sign see almekinders 1995 chapter 6 baillie and humpage 1992 dominguez 1998 dominguez and frankel 1993 klein and rosengren 1991 lindberg 1994 and osterberg and wetmore humes 1995 during the last decade the bulk of the empirical research has concentrated on the analysis of daily or weekly data this line of research which adopts the view that exchange rate markets are highly efficient was stimulated by the decision of the federal reserve board and the deutsche bundesbank to make their daily intervention data available to outside researchers to rationalise the gap between the fragile empirical evidence and the manifest interest paid by the media and other observers to interventions various explanations have been offered in this paper we stress two measurement problems first there is the problem of properly defining the exchange rate change in the regression analysis since intervention exchange rates are not available the

the ecological fallacy revisited aggregate versus individual level findings on economics and elections and sociotropic voting several aggregate level studies have found a relationship between macroeconomic conditions and election outcomes operating in intuitively plausible directions more recent survey based studies however have been unable to detect any comparable relationship operating at the individual voter level this persistent discrepancy is puzzling one recently proposed explanation for it is that voters actually behave in an altruistic or sociotropic fashion responding to economic events only as they affect the general welfare rather than in terms of self interested pocketbook considerations it is argued here that the discrepancies between the macro and micro level studies are a statistical artifact arising from the fact that observable changes in individual welfare actually consist of two unobservable components a government induced and politically relevant component and an exogenous component caused by life cycle and other politically irrelevant factors it is shown that because of this individual level cross sectional estimates of the effects of welfare changes on voting are badly biased and are essentially unrelated to the true values of the behavioral parameters of interest they will generally be considerable underestimates and may even be of the wrong sign an aggregate level time series analysis on the other hand will often yield reasonably good if somewhat attenuated estimates of the underlying individual level effects of interest thus in this case individual behavior is best investigated with aggregate rather than individual level data it is also shown that the evidence for sociotropic voting is artifactual in the sense that the various findings and evidence which ostensibly show sociotropic behavior are all perfectly compatible with the null hypothesis of self interested pocketbook voting

are forign exchange intervention and monetary policy related and does it really matter the relationship between foreign exchange intervention and monetary policy underlies the question of whether sterilized interventions can affect the exchange rate in this article the author examines this relationship using data on u s foreign exchange interventions from 1985 to 1990 recently made publicly available she examines whether interventions could be viewed as signaling changes in future monetary policy variables the author also considers whether changes in monetary policy may induce interventions in an effort by central bankers to lean against the wind of exchange rate movements interestingly she finds evidence both that interventions help predict monetary policy variables and that monetary variables help predict interventions copyright 1995 by university of chicago press

clarity of responsibility beyond the pocketbook how political institutions condition eu issue voting one of the most influential findings of the voting behavior literature of the past two decades was the realization that the clarity of the domestic institutional context influences the relationship between economic perceptions and incumbent vote this article extends this clarity of responsibility argument beyond economics to another policy field european integration to what extent do national political institutions mediate the extent to which voters reward or punish government for their policies relating to the european union eu or european integration that is eu issue voting using data from the 2004 european election study the authors provide evidence that clarity of responsibility affects the strength of eu issue voting specifically eu issue voting is accentuated when the domestic institutional environment provides clear lines of responsibility this finding suggests that the europeanization of national electoral politics depends in part on the domestic institutional context within each me

party identification retrospective voting and moderating elections in a federal system west germany 1961 1989 the hypotheses of retrospective voting and moderating elections rationalize some empirical regularities in u s presidential and congressional elections that posed a challenge for the party identification hypothesis here these hypotheses are applied to the german federal system that is characterized by staggered national and land provincial elections they are tested using data on real gnp growth at the national and land levels party vote shares in national and land elections party seat shares in national and land parliaments and the party composition of national and land governments over the time period 1961 1989 perhaps surprisingly all three hypotheses party identification retrospective voting and moderating elections find empirical support when applied to the german federal system although these hypotheses were formulated with reference to u s political institutions they travel well bar some modifications that take into account special features of the german political system

don t stand so close to me spatial contagion effects and party competition in this article we bring together elements from the literatures on economic voting and spatial voting to gain theoretical leverage on the combined role of clarity of responsibility party policy positions and economic performance in elections building on evidence of voter knowledge we develop a theory of spatial contagion effects to explain how factors drawn from both of these literatures combine to shape changes in support for political parties we test this theory with a spatial autoregressive model of party competition in 23 nations from 1951 to 2005 as expected we find evidence of strong spatial contagion effects in elections with low clarity of responsibility

bubble thy neighbor portfolio effects and externalities from capital controls we use changes in brazil s tax on capital inflows from 2006 to 2013 to test for direct portfolio effects and externalities from capital controls on investor portfolios we find that an increase in brazil s tax on foreign investment in bonds causes fund managers to significantly decrease their portfolio allocations to brazil in both bonds and equities fund managers simultaneously increase allocations to other countries that have substantial exposure to china and decrease allocations to countries viewed as more likely to adjust their capital controls much of the effect of capital controls on portfolio allocation appears to occur through signalling i e changes in investor expectations about future policies rather than the direct cost of the controls this evidence of significant externalities from capital controls suggests that any assessment of controls should consider their effects on portfolio flows to other countries

economic outcomes and voting behaviour in a multi party system an application to the netherlands this paper is an empirical study to the effects of economic outcomes on party choice for the netherlands in the first part of the paper we employ a multinomial logit model to examine the links between voters characteristics and party choice the results suggest that there are long run movements in party choice which are unlikely be the result of changing economic outcomes in the second part we use time series analysis to determine the effects of economic conditions on short run and medium run movements in votes shares the estimations results provide support for the responsibility hypothesis and for the predictions of the partisan voter model that left wing right wing parties benefit suffer from favourable economic growth prospects

exchange rate management in emerging markets intervention via an electronic limit order book this paper describes and analyzes the implementation of a crawling exchange rate band on an electronic trading platform the placement of limit orders at the central bank s target rate serves as a credible policy statement that may coordinate beliefs of market participants we find for our sample that intervention increases exchange rate volatility and spread for the next minutes but that intervention days show a lower degree of volatility and spread than non intervention days we also show for intraday data that the price impact of interbank order flow is smaller on intervention days than on non intervention days these stabilizing effects however rely on the conditions of large currency reserves and the existence of capital controls an electronic market seems to support this goal

foreign currency government debt asset markets and balance of payments abstract foreign currency government borrowing has implications for modelling asset markets and the balance of payments geographical balance of payments flows can be misleading indicators of exchange rate pressures in a world characterized by foreign currency govenment debt because the latter alter the currency composition of global asset supplies in a manner similar to foreign exchange market intervention a theoretical currency reinterpretation of the balance of payments is proposed and some estimates of the magnitude oecd foreign currency government borrowing are offered however more comprehensive measures of asset supplies may not by themselves improve the performance of simple portfolio balance models

insuring against losses from transgenic contamination the case of pharmaceutical maize concerns about the risk of food supply contamination have limited the development and commercialization of certain pharmaceutical plants this article develops an insurance pricing model that helps translate these concerns into a cost benefit analysis the model first estimates the physical dispersal of maize pollen subject to a number of weather parameters this distribution is then validated with the limited amount of currently available field trial data the physical distribution is then used to calculate the premium for a fair valued insurance policy that would fund the destruction of possibly contaminated fields the flexible framework can be readily adapted to other crops management practices and regions

the hedging role of options and futures under joint price basis and production risk this paper analyzes the optimal production and hedging decisions for firms facing futures price basis and production risk assuming futures and options can be used using constant absolute risk aversion utility and normal distributions the authors derive an exact solution and show that joint production and price risk lead to a hedging role for options risk averse firms that can use each hedging instrument will generally have higher expected output using iowa data for soybeans the parameters of the joint distribution of future prices cash prices and yields are estimated and the results are used to approximate optimal hedging decisions for soybean producers copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

is it signalling exchange intervention and the dollar deutschemark rate abstract the portfolio balance channel for sterilised intervention is tested by examining the effects of changes in relative asset supplies on the dollar deutschemark rate during the 1980s in contrast to previous studies we control for any signalling effects of central bank intervention and find a weak but statistically significant portfolio balance influence on the exchange rate
