the effect of slack diversification and time to recall on stock market reaction to toy recalls abstract past toy recalls have led to an increase in consumer concerns while toy manufacturers and retailers increasingly outsource and create longer supply chains making it more challenging for them to ensure toy safety this article examines firms making toy recall announcements to assess the impact operational characteristics have on the negative stock market reaction to the announcement 135 toy recall announcements in the u s from 1979 to 2016 were analyzed using event study and cross sectional regression while a toy recall announcement results in a negative stock market reaction our results show that greater levels of business diversification inventory slack and a longer time to recall are all associated with a less negative stock market reaction in contrast greater capacity slack is associated with a more negative stock market reaction we find no evidence that geographic diversification or financial slack influences the stock market reaction nor have reactions changed appreciably over time this article contributes to the product harm and product recall literature by focusing on these operational elements managers should be aware of the benefits of greater slack and business diversification while planning their business and the impact of a longer time to recall

stock price reactions as surrogates for the net cash flow effects of corporate policy decisions abstract this paper adopts a rational market structure to examine the link between the cash flow effects of management policy decisions and the resulting stock price reactions the focus is on testing cross sectional associations between cash flow effects and the underlying characteristics of affected firms we find that it is not possible to infer the sign of association between the stock price reaction and any characteristics of the firm that are observable before management announces its decision our methodological suggestions involve exploiting either a priori assumptions or sample information about the probability distribution of unobservable decision variables underlying the management decision process

credit risk measurement developments over the last 20 years abstract this paper traces developments in the credit risk measurement literature over the last 20 years the paper is essentially divided into two parts in the first part the evolution of the literature on the credit risk measurement of individual loans and portfolios of loans is traced by way of reference to articles appearing in relevant issues of the journal of banking and finance and other publications in the second part a new approach built around a mortality risk framework to measuring the risk and returns on loans and bonds is presented this model is shown to offer some promise in analyzing the risk return structures of portfolios of credit risk exposed debt instruments

contagion during the greek sovereign debt crisis abstract we examine the impact of news about greece and news about a greek bailout on bank stock prices in 2010 using data for 48 european banks we identify the twenty days with extreme returns on greek sovereign bonds and categorise the news events during those days into news about greece and news about the prospects of a greek bailout we find that except for greek banks news about greece does not lead to abnormal returns while news about a bailout does even for banks without any exposure to greece or other highly indebted euro countries this finding suggests that markets consider news about the bailout to be a signal of european governments willingness in general to use public funds to combat the financial crisis sovereign bond prices of portugal ireland and spain respond to both news about greece and news about a greek bailout

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

public information as a deterrent to environmental infractions past studies of the impact of publicly announced violations of environmental laws on the market value of the offending firms have yielded equivocal results a particularly troubling aspect of this research is whether the market imposes a reputation penalty for such violations this article uses the event study methodology to estimate the effect of announced environmental infractions on the market returns of the violators stockholders experienced significant negative abnormal returns in the event window cross sectional analysis showed these cumulative losses to be a function of firm size type of legal action and specific toxin the reputation component of abnormal returns was influenced by these factors as well

trading on inside information evidence from the share structure reform in china abstract we examine stock trading activities in days before chinese listed firms made public announcement to start share structure reform there is significant evidence that relative to a benchmark period institutional investors bought more event firms shares in the last two trading days prior to announcement randomization tests show significant differences in institutional trading activities between event firms and matched control firms which suggests that some institutions had inside information moreover large trades account for a significant proportion of daily stock price changes in the last 2 days the evidence is consistent with the prediction by holden and subrahmanyam 1992 that when multiple informed investors acquire the same piece of information they will trade aggressively we also find that over the reform period the median share value change of event firms is 6 higher than that of control firms our findings have important implications for enforcement of insider trading regulations in china

consistent estimation of cross sectional models in event studies event studies often include cross sectional regressions of announcement effects on exogenous variables if the event is voluntary and investors are rational then standard ols and gls estimators are inconsistent consistent ml estimators are constructed for a cross sectional model of horizontal mergers relating announcement effects to exgeneous characteristics of firms and industries the ols and ml estimates differ dramatically for bidders but not for targets the evidence suggests that managers of bidders but not targets have valuable private information about the potential synergies from proposed mergers article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

official intervention in the foreign exchange market or bet against the central bank evaluating official foreign exchange intervention during the 1970s using friedman s profit criterion shows that central banks have failed to stabilize the exchange markets and have lost billions of dollars the monetary authorities have resisted rate movements which results in a misallocation of resources when there is a shift in the equilibrium exchange rate counterspeculation by exchange traders reduces the destabilizing effect of central bank intervention and the consequent loss in economic welfare

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

foreign exchange intervention how to signal policy objectives and stabilise the economy abstract within a simple model of monetary policy for an open economy we study how foreign exchange intervention may be used as a costly signal of the policy makers objectives our analysis indicates that i foreign exchange intervention typically stabilises the national economy reducing the fluctuations of employment and output ii this result is sensitive to the institutional structure of decision making in that a larger stability gain is obtained when foreign exchange intervention and monetary policy are kept under the jurisdiction of different governmental agencies

on multivariate tests of the capm abstract this paper evaluates the power of multivariate tests of the capital asset pricing model the results indicate that when employing an unspecified alternative hypothesis the ability of the tests to distinguish between the capm and other pricing models is poor an upper bound is derived for the distance the alternative distribution of the test statistic can be from the null distribution when the deviations from the capm are due to missing factors this upper bound explains the low power of the tests

a note on the use of industry relative ratios in bankruptcy prediction abstract the potential for industry relative financial ratios to improve the prediction of firms in financial distress motivated this comparison of model specifications based on either unadjusted or industry relative ratios both specifications yielded stable parameter estimates over the time periods examined however the industry relative specification appeared to add incremental information not contained in the model based on the unadjusted financial ratios the converse case did not hold in addition with the industry relative specification ex post forecast accuracy was slightly improved relative to the ex ante forecast while with the unadjusted model specification ex post forecast accuracy declined from that obtained ex ante

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

the impact of fraudulent false information on equity values there are two types of stock price manipulation examined in the theoretical literature 1 insider trading which involves private information that is true and 2 the public spreading of fraudulent false information while there is a large empirical literature on insider trading this is the first empirical article to examine the impact of false fraudulent public information on stock prices and trading volume we find that such false information even after being denied by a credible source such as the sec generates both abnormal returns and abnormal trading volume we also find that the effects of the false information on security returns and volume can be persistent for at least 2 weeks in addition we show that perpetrators of false news attacks can make potentially large profits from such market manipulations

does the fed beat the foreign exchange market abstract this paper s estimates and tests of fed intervention profits are the first that explicitly adjust for foreign exchange risk premia failure to adjust may grossly affect estimated profits profits appear economically and statistically significant whether risk premia are modeled as time constant or as appreciation s market beta depending on fed intervention the estimates are sensitive to the method of risk adjustment and to the periods used because a key variable cumulative intervention is i 1 test statistics may have non standard distributions a problem affecting past tests this paper s tests account for non standard distributions possible explanations of these profits have mixed empirical support in the literature

the profitability of us intervention in the foreign exchange markets abstract using a formula for intervention profits in which profitability measured as of date t depends on how well intervention operations predict ex post deviations from interest parity this paper shows that us intervention since the beginning of generalized floating in 1973 has earned profits for the us monetary authorities fundamental explanations for the profitability of us intervention are difficult to isolate but statistical tests suggest that it is unlikely the profits are merely the outcome of chance or a normal return to bearing time invariant risk

investigating security price performance in the presence of event date uncertainty abstract this paper introduces an event study method that incorporates the possibility of a random event date consistent with empirical evidence we assume an event may affect not only the conditional mean of a security s return but also its conditional variance we compare the statistical power and efficiency of our maximum likelihood method with the standard application of traditional event study methods to multiday security returns assuming a two day event period our empirical results provide evidence that the multiday approach is robust we use our maximum likelihood method to investigate the valuation effects of stock splits and stock dividends

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

exchange rate speculation and chaos inducing intervention abstract we show that in a market characterized by high volatility transactions designed to have a stabilizing effect may inadvertently induce chaos in the foreign exchange market for example excessive interventions by a central bank may lead to an increase in erratic behavior rather than to the calming of exchange rate movements

an analysis of the impact of deposit rate ceilings on the market values of thrift institutions this paper examines the impact of changes in deposit interest rate regulations on the common stock values of savings and loan institutions the analysis indicates that stockholder owned savings and loans s l s have experienced statistically significant declines in equity market values at the announcement of the removal of ceilings on certain consumer small saver certificate accounts and the introduction of short term variable rate money market certificates we find the evidence to be consistent with the hypothesis that s l s have earned economic rents from restrictions on interest rates paid to small saver accounts and that relaxation of interest rate ceilings has reduced these rents a central issue in the economics of regulation is whether regulators behave in a way that primarily benefits the economic agents whose actions they are supposed to regulate the proposition that regulation is demanded and acquired by the regulated and that regulations are designed and administered primarily for their benefit was originally put forth by stigler 19 and has come to be known as the capture theory of regulation an alternative view is that regulators adopt policies which serve some other perhaps public or possibly the regulators own interest and that administration of these policies does not benefit the regulated entities this paper examines the regulation of savings and loan associations deposit interest rates and reports evidence pertaining to the impact of the administration of regulation regulation of interest rates paid to depositors in federally insured savings and loan associations began in 1966 since that time several changes in the maximum allowed interest rates deposit rate ceilings have been made these changes present an opportunity to observe the impact of one form of regulatory action on savings and loan institutions deposit rate regulation has been the subject of extensive previous research the empirical investigations have focused primarily on two issues 1 the allocational efficiency and wealth redistribution effects of rate ceilings and 2 the impact of deposit rate ceilings on the flow of funds into the residential

an econometric analysis of the choice of daily versus monthly returns in tests of information content studies investigating the association between information events and security returns are common in accounting and finance 1 earlier studies used monthly return data but the recent availability of daily return data confronts the researcher with a decision on which type of return data is more appropriate in this paper i examine some econometric issues on the choice between monthly and daily return data the analysis is easily extended to weekly return data which has been used in some information event studies the purpose of this paper is to examine factors affecting the power of statistical tests to investigate the effect of information on security returns based on return data over different units of time one set of factors affecting the power of the tests pertains to the characteristics of the information event such as 1 the existence of confounding information events during the same period as the information event of interest 2 uncertainty about the magnitude of the effect of the information event on security returns and 3 uncertainty about

derived factors in event studies abstract we examine the utility of the statistical factor model of the process generating stock returns in the context of event studies for a variety of estimation procedures and experimental designs we find limited value added relative to the use of a simple market model we would attribute this finding to misspecification of the statistical factor analysis model and suspect that there exist more robust procedures for estimating the factor structure of stock returns

how to make the central bank look good a reply in his original 1982 paper dean taylor proposes a simple test of the significance of central bank losses in the exchange market would random intervention be likely to result in as large a loss my comment spencer 1985 took his model at face value but showed that his test statistic was misspecified and that the question he posed was ambiguous yielding two alternative criteria in his comment this issue taylor has shown that if in fact central banks lean into the wind then one of these criteria is biased but this analysis raises a general question about the use of profitability indicators it shows that the conditional nature of these calculations makes them unstable and prone to manipulation when central banks lean into the wind

an estimation of the hazard rate of firms under chapter 11 protection the instantaneous probability hazard rate of a firm s exit from chapter 11 protection is examined using the weibull duration model the effect of various regressors and the effect of the time a firm spends under chapter 11 protection on this instantaneous probability is analyzed i show that the hazard increases significantly under chapter 11 among the variables chosen the interest burden of the firm and the capacity utilization of the firm s industry significantly increase the hazard other firm specific variables like the long term debt to assets ratio and the number of shares outstanding and economy wide variables like the prime interest rate and the gross national product growth rate have no significant effect on the hazard copyright 1994 by mit press

do markets care who chairs the central bank this paper assesses the effects of central bank governor appointments on financial market expectations of monetary policy to measure these effects we assemble a new dataset of appointment announcements from 15 countries and conduct an event study analysis on exchange rates bond yields and stock prices our main findings are threefold first exchange rates and bond yields display a statistically significant response to the announcement of a new governor especially when the appointee s identity was not anticipated in advance second the reactions are especially pronounced for central banks lacking either independence or a clear nominal anchor third new governors are not generally perceived to lack credibility there is no tendency for announcements to be associated with jumps in inflation expectations

the cost of a central bank leaning against a random walk abstract using a stochastic model we show that a central bank is expected to suffer a loss when it temporarily affects the exchange rate by sterilized intervention against a random walk we also demonstrate that the methodology used in several studies of the profitability of official central bank intervention biases their results towards finding positive profits this bias created by only observing periods where cumulative intervention sums to zero accounts for the seemingly contradictory empirical results of several intervention profitability studies

market in efficiency in valuing electric utilities the case of norwegian generating companies after deregulation of the energy market in norway a number of mergers and acquisitions of hydropower generating companies have taken place however valuation of these companies has proved controversial from an ex post perspective there is support for the criticism that generation assets have been sold too cheaply this article presents a simple valuation model providing evidence of how value has evolved on the basis of these results we discuss the valuation from an ex ante perspective and in the light of the market efficiency hypothesis of fama 1970 1991

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

do central banks lose on foreign exchange intervention a review article abstract estimates of central bank intervention losses or profits vary widely some estimates find substantial losses others profits in most cases estimated profits are not risk adjusted and risk adjustment can have large effects furthermore profit estimates involve variables integrated of order one and because of this test statistics may have nonstandard distributions few studies take this into account estimates of risk adjusted profits for the us fed and the swedish riksbank with allowances for possible nonstandard distributions suggest that neither made losses and might have made significant profits

how to make the central bank look good in a comment on my article taylor 1982b that uses friedman s 1953 profit criterion to evaluate official foreign exchange intervention peter spencer 1985 proposes an alternative criterion for measuring the success of intervention that deducts the effect of the mean level of intervention his criterion is seriously flawed by a strong positive bias in favor of the central bank if it pursues a policy of leaning against the wind this reply uses a stochastic model that assumes that the exchange rate follows a random walk and that the central bank leans against the wind although this is a fair game with the expected profit equal to zero spencer s criterion is biased to show positive results for the central bank approximately 96 percent of the time in addition his empirical results are exaggerated by his misinterpretation of his test statistic as the slope coefficient for a regression with a constant the model s assumptions that exchange rate changes are independent and that the central bank leans against the wind are empirically good first approximations evidence on the independence of exchange rate changes is provided in studies such as levich 1978 mussa 1979 frenkel 1981 and dooley and shafer 1984 which show that the random component of exchange rate changes overwhelmingly dominates any systematic behavior in exchange rate movements evidence presented in taylor 1982a shows that central banks lean against the wind by selling dollars when the price of the i am indebted to howard stratton and charles corrado for helpful suggestions and help with the simulations i have also benefited from comments from peter spencer michael bordo michael connolly todd sandler sam peltzman and a referee of course they are not responsible for any remaining errors

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

stock market reaction to financial statement certification by bank holding company ceos in 2002 the sec mandated that the ceos of large publicly traded firms certify the accuracy of their company financial statements the sec s certi fication order provides a natural experiment that gives insight into the question of whether banks are opaque we find that the bhcs subject to the sec s order experienced positive and significant average abnormal returns from certification characteristics associated with greater opaqueness liquid asset holdings information intensive lending and split credit ratings are systematically associated with the size of abnormal returns

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

cointegration fractional cointegration and exchange rate dynamics multivariate tests due to johansen 1988 1991 as implemented by baillie and bollerslev 1989a and diebold gardeazabal and yilmaz 1994 reveal mixed evidence on whether a group of exchange rates are cointegrated further analysis of the deviations from the cointegrating relationship suggests that it possesses long memory and may possibly be well described as a fractionally integrated process hence the influence of shocks to the equilibrium exchange rates may only vanish at very long horizons in the article by baillie and bollerslev 1989a it is argued that seven different nominal spot and forward exchange rates all contain unit roots in their univariate time series representations at the same time however the spot exchange rates appear to be tied together in the long run through a cointegration type relationship the latter finding of baillie and bollerslev has attracted particular interest and several studies such as those by hakkio and rush 1991 and sephton and larsen 1991 have already addressed this issue using the same data as the baillie and bollerslev article sephton and larsen 1991 describe the evidence for the presence of cointegration as being fragile and note that mixed conclusions are reached by truncating the baillie and bollerslev sample at different points in time diebold gardeazabal and yilmaz 1994 henceforth diebold et al provide interesting evidence that application of the johansen 1988 1991 tests with and without an intercept will result in different inferences on the baillie and bollerslev data set furthermore diebold et al carry out an ex ante forecasting experiment and find that the addition of an error correction term to the martingale model as implied by the standard cointegration paradigm fails to reduce the prediction mean square error when compared to a simple martingale model this therefore leads diebold et al to conclude that there exists substantial uncertainty regarding the existence of cointegration relationships among nominal dollar exchange rates this article provides some additional evidence on the existence of such a long run relationship among the same seven nominal spot exchange rates after further analysis it appears that a form of cointegration does exist between the exchange rates so that they do not drift apart in the long run we argue that this form of cointegration is

measurement error and the profitability of interventions a closer look at snb transactions data abstract several studies argue that central bank profits from foreign exchange interventions should be calculated using daily data the rationale is that intra month exchange rate volatility is larger than the intra day volatility this note tests this hypothesis with transactions data

random effects logistic regression model for default prediction of technology credit guarantee fund korean government has been funding the small and medium enterprises sme with superior technology based on scorecard however high default rate of funded smes has been reported in order to effectively manage such governmental fund it is important to develop accurate scoring model for smes in this paper we provide a random effects logistic regression model to predict the default of funded smes based on both financial and non financial factors advantage of such a random effects model lies in the ability of accommodating not only the individual characteristics of each sme but also the uncertainty that cannot be explained by such individual factors it is expected that our study can contribute to effective management of government funds by proposing the prediction models for defaults of funded smes

standard errors in event studies even if true abnormal returns are uncorrelated estimated abnormal returns are not this paper presents a simple formula for the variance of estimated cumulative abnormal re turns both returns and dummy variable procedures for estimating the standard error correctly taking account of both intertemporal and contemporaneous correlation of esti mated residuals are discussed they are then applied to an event study of post merger performance it is shown that ignoring either the intertemporal or contemporaneous correlation of residuals can result in significant underestimates of standard errors

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

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

market response to policy initiatives during the global financial crisis abstract this paper examines the impact of macroeconomic and financial sector policy announcements in the united states the united kingdom the euro area and japan on interbank credit and liquidity risk premia during the recent crisis overall policy interventions were associated with a reduction in interbank risk premia most significantly for recapitalization programs by contrast decisions to bail out individual banks in an ad hoc manner or let them fail were accompanied by a significant rise in interbank risk premia most policy announcements had international spillovers these results are broadly robust to using alternative measures of financial distress and varying the size of the event window

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach

the foreign exchange costs of central bank intervention evidence from sweden abstract this study presents evidence on risk adjusted profits for the swedish central bank estimated profits can be quite sensitive as to whether rates of return are risk adjusted or not and how the risk adjustment is done various ways of adjusting for abnormal returns and extracting buy sell signals are tried results on daily data support the view that riksbank intervention did not make risk adjusted losses over the period 1986 1990 the results might be challenged as arising from inappropriate risk adjustment

common stochastic trends in a system of exchange rates univariate tests reveal strong evidence for the presence of a unit root in the univariate time series representation for seven daily spot and forward exchange rate series furthermore all seven spot and forward rates appear to be cointegrated that is the forward premiums are stationary and one common unit root or stochastic trend is detectable in the multivariate time series models for the seven spot and forward rates respectively this is consistent with the hypothesis that the seven exchange rates possess one longrun relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates a general consensus has emerged in recent years that many macroeconomic time series such as gnp consumption expenditures disposable income etc can be characterized by a stochastic trend model in particular nelson and plosser 22 described this property as one of being difference stationary so that the first difference of a time series is stationary an alternative trend stationary model where a stationary component is added to a deterministic trend term has generally been found to be less appropriate 1 similarly it has long been recognized that many financial time series such as foreign exchange rates are nonstationary e g in meese and singleton 21 the issue of nonstationary is not merely a statistical curiosity but has several important implications for the modeling of exchange rates for instance many models of exchange rate determination under rational expectations require stationarity assumptions when solving out the expected future values of the fundamentals further there has been some controversy over the appropriate transformations to use when conducting tests of whether the forward rate is an unbiased and efficient predictor of the future spot exchange rate 2 some authors e g frenkel 11 12 have conducted tests in levels while geweke and feige 14
