the bond old bond spread abstract i document the profits on a trade that is long the old 30 year treasury bond and short the new 30 year treasury bond and is rolled over every auction cycle from june 1995 to november 1999 despite the systematic convergence of the spread over the auction cycle the average profits are close to zero the difference in repo market financing rates between the two bonds is a significant cost of carry in this trade i show that variation in the bond old bond spread is driven by the treasury supply of 30 year bonds as well as aggregate factors affecting investors preference for liquid assets

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

exchange rate effects of financial regulations abstract in this paper we analyze the effects of financial constraints on the exchange rate through the portfolio balance channel we use a sharp policy discontinuity within the colombian financial system to empirically test for the portfolio balance channel using high frequency data during the period of 2004 2015 our findings suggest that the effects on the exchange rate are short lived and significant only when banking constraints are binding to understand the mechanism behind this result we construct a tractable two period general equilibrium model in which banking limits on foreign holdings inhibit capital flows when these limits bind departures from the uncovered interest rate parity enable sterilized foreign exchange interventions to influence the exchange rate

foreign exchange market intervention and expectations the yen dollar exchange rate abstract using press reports and official statistics on central bank intervention in conjunction with options market data we find that central bank intervention had no statistically significant systematic impact on the mean or higher moments of the exchange rate during 1993 2000 we also find that japanese authorities appeared to intervene mainly in response to deviations of the exchange rate from some implicit target levels and to a rise in market uncertainty u s monetary authorities intervened only in cooperation with the japanese authorities

monetary policy actions intervention and exchange rates a reexamination of the empirical relationships using federal funds rate target data the authors reexamine the relationships among federal reserve monetary policy actions u s interventions in currency markets and exchange rates using an alternative measure of monetary policy actions the federal reserve s federal funds rate target they find that exchange rates generally respond immediately to u s monetary policy actions and that these responses are usually consistent with the overshooting hypothesis the authors also find evidence of signaling and leaning against the wind u s intervention policies over the sample however controlling for such interventions do not alter their estimates of exchange rate responses to federal funds rate target changes copyright 1998 by university of chicago press

do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods dauth w hujer r and wolf k do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods regional studies the effect of active labour market policies on all job seekers in a region is assessed using the variation in the participation in these programmes across regions over time the starting point is an augmented regional matching function which is extended by allowing for a heterogeneous search effectiveness parameter for current participants and job seekers who finished a measure recently a spatial dynamic panel data model is estimated by using a quasi ml estimation procedure it is found that job schemes in the non profit sector wage subsidies and advancement of apprenticeships significantly increase the regional number of matches

regime switching in the relationship between equity returns and short term interest rates in the uk abstract this paper examines the relationship between uk equity returns and short term interest rates using a two regime markov switching egarch model the results suggest one high return low variance regime within which the conditional variance of equity returns responds persistently but symmetrically to equity return innovations in the other low mean high variance regime equity volatility responds asymmetrically and without persistence to shocks to equity returns there is evidence of a regime dependent relationship between shorter maturity interest rate differentials and equity return volatility furthermore there is evidence that events in the money markets influence the probability of transition across regimes

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

exchange rate return predictability and the adaptive markets hypothesis evidence from major foreign exchange rates this study examines return predictability of major foreign exchange rates by testing for martingale difference hypothesis mdh using daily and weekly nominal exchange rates from 1975 to 2009 we use alternative mdh tests for linear and nonlinear dependence which include wild bootstrap automatic variance ratio test generalized spectral test and consistent tests we evaluate time varying return predictability by applying these tests with fixed length moving sub sample windows of two years while exchange rate returns are found to be unpredictable most of times we do observe episodes of statistically significant return predictability they are associated with coordinated central bank interventions and the subprime mortgage crisis in 2007 this finding suggests that return predictability of foreign exchange rates occurs from time to time depending on changing market conditions which is consistent with the implications of the adaptive markets hypothesis

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

high frequency analysis of foreign exchange interventions what do we learn abstract the high frequency analysis of foreign exchange dynamics is helpful in order to better identify the impact of central bank interventions evidence robustly shows that interventions do indeed move the exchange rate level in the desired direction interventions increase volatility in the short run as they are regarded as information but they can reduce volatility overall ways of transmission may reach beyond the signalling channel and also include the portfolio balance and a damping channel finally interventions are more successful if they obey certain conditions such as being coordinated among central banks and going with the market and fundamentals

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

a model of competition between unemployed and employed job searchers an application to the unemployment outflow rate in britain this paper proposes a model to explain the allocation of new jobs to workers the central innovation is the analysis of the competition for jobs between employed and unemployed job searchers it is argued that the endogeneity of the fraction of the employed engaging in search is a crucial determinant of the unemployment outflow rate the model is applied to the unemployment outflow rate in britain the model fits the data well and encompasses its main rival copyright 1993 by royal economic society

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

do macro economic news announcements affect the volatility of foreign exchange rates some evidence from australia this paper investigates the role of australian macro economic announcement news on five major australian dollar aud exchange rates specifically the daily changes of the exchange rates are modelled to ascertain the existence and the nature of the news effects in the conditional mean and variance of the changes it is found that a higher than expected current account deficit and unemployment rate announcements depreciated the aud and an unexpectedly higher gdp growth announcement appreciated it current account deficit cpi and unemployment news announcements significantly raised the conditional volatility of the changes of the aud on the days of their announcements except for the bp aud for the cpi news and there is some evidence of retail sales news reducing it in general the evidence is consistent with a view that a release of new information creates uncertainty in the markets due to a lack of consensus on the effects of the particular news announcement and the necessary course of action in add

do employers use unemployment as a sorting criterion when hiring evidence from a field experiment the stigma associated with long term unemployment spells could create large inefficiencies in labor markets while the existing literature points toward large stigma effects it has proven difficult to estimate causal relationships using data from a field experiment we find that long term unemployment spells in the past do not matter for employers hiring decisions suggesting that subsequent work experience eliminates this negative signal nor do employers treat contemporary short term unemployment spells differently suggesting that they understand that worker firm matching takes time however employers attach a negative value to contemporary unemployment spells lasting at least nine months providing evidence of stigma effects

unemployment duration unemployment benefits and labor market programs in sweden abstract standard search theory as well as some empirical evidence suggest that an unemployed individual s probability of entering employment increases as he approaches the time when unemployment benefits are due to expire this pattern may not carry over to a country like sweden where labor market programs are targeted at the long term unemployed at risk of benefit exhaustion the paper examines transitions out of unemployment using data on unemployed individuals in sweden a semi parametric competing risks model for transitions to employment labor market programs and non participation is estimated there is some evidence that the exit rate from unemployment to employment increases as benefit exhaustion is approached

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

intervention strategies and exchange rate volatility a noise trading perspective abstract this paper estimates and explains the impacts of sterilized us intervention on exchange rate volatility i find that intervention reduced both yen dollar and dm dollar exchange rate volatilities during 1985 1986 but increased them during 1987 1989 these results are explained in a noise trading framework where the effectiveness of sterilized intervention may depend critically on the design and implementation of intervention strategies jel f31 1997 elsevier science ltd

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

liquidity maturity and the yields on u s treasury securities the efrect8 of aaaet liquidity on expected retuma for ts with infinite maturities toc ka are eumined for bonda treuury notes and bills with matched maturities of lellll than 6 months the yield to maturity ill higher on notes which have lower liquidity the yield di1ferential between notes and billa is a decreuing and convex function of the time to maturity the results provide a robult confirmation of the liquidity effect in auet pricing this paper studies empirically the effects of the liquidity of capital assets on their prices amihud and mendelson 1986 1989 proposed that liquidity affects asset prices because investors require a compensation for bearing transaction costs transaction costs paid whenever the asset is traded form a sequence of cash outflows the discounted value of this cost stream proxies for the value 1088 due to illiquidity which lowers the asset s value for any given cash flow that the asset generates 1 as a result the return on assets should be an increasing function of their illiquidity other things equal for stocks the illiquidity effect is expected to be strong because their transaction cost sequence is infinite amihud and mendelson 1986 1989 demonstrated that common stocks with lower liquidity yielded significantly higher average returns after controlling for risk and for other factors these results on the importance of liquidity in the pricing of stocks raise additional questions i does the liquidity effect depend on the specific controls used by amihud and mendelson 1986 1989 1 ii does illiquidity have a similarly strong effect on the pricing of bonds whose maturities are finite and iii if liquidity affects bond yields how is this effect related to the bond s time to maturity

asset market linkages evidence from financial commodity and real estate assets abstract we use a general markov switching model to examine the relationships between returns over three different asset classes financial assets us stocks and treasury bonds commodities oil and gold and real estate assets us case shiller index we confirm the existence of two distinct regimes a tranquil regime with periods of economic expansion and a crisis regime with periods of economic decline the tranquil regime is characterized by lower volatility and significantly positive stock returns during these periods there is also evidence of a flight from quality from gold to stocks by contrast the crisis regime is characterized by higher volatility and sharply negative stock returns along with evidence of contagion between stocks oil and real estate furthermore during these periods there is strong evidence of a flight to quality from stocks to treasury bonds

job search stigma effect and escape rate from unemployment this article formulates job search models incorporating certain types of the stigma effect of unemployment it is assumed that the probability of getting a job offer given the unemployment individual contacts the firm is influenced by the duration of unemployment and is justified in a signaling context the optimal search is analyzed for one sector as well as across several independent labor market segments it is shown that there are reasonably general conditions on the search environments for which both the individual reservation wage and escape rate are negative duration dependent a fact observed in empirical studies

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

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

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

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

foreign exchange intervention when interest rates are zero does the portfolio balance channel matter after all abstract this paper provides an empirical investigation of transmission channels of central bank foreign exchange intervention when interest rates are zero and traditional monetary policy options are constrained the paper develops empirically testable hypotheses regarding the functioning of the intervention transmission channels under study these hypotheses evolve around whether or not the market is aware or unaware of intervention official daily data on interventions in the jpy usd market during the 1999 to 2004 japanese zero interest rate period facilitate the analysis the results of the analysis are consistent with the suggestion that intervention when interest rates are zero works through the portfolio balance channel

effects of exchange rate variability on inflation variability abstract previous studies have postulated that there exists a positive relationship between the rate of inflation and its variability they have shown that a high inflation rate contributes to inflation variability in this paper we argue that with the current floating exchange rate system exchange rate variability is another factor contributing to inflation variability after incorporating a measure of exchange rate variability into a simple model used by previous authors we estimate our model using cross country data from 20 developed and 76 less developed countries the cross sectional regression results support our conjecture

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

raiding opportunities and unemployment this article studies the impact of raiding opportunities in a labor market in which worker abilities differ recruiting firms can either raid an elsewhere employed worker of known ability by bidding up his wage or go through costly search to find a good worker among the unemployed in equilibrium all types of workers experience unemployment high ability workers involuntarily the raiding opportunities give rise to involuntary unemployment without changing the basic properties of the competitive model and thus suggest new implications of various institutional parameters on unemployment in particular unemployment compensation minimum wages wage taxation and search requirements

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

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

the effectiveness of foreign exchange interventions under a floating exchange rate regime for the turkish economy a post crisis period analysis the reported study has two purposes first it attempts to improve the literature on foreign exchange interventions of the central banks for the emerging market economies an area not previously studied in detail the turkish economy in the post crisis period constitutes a good example in this context second it proposes a new methodology a time varying parameter model to analyse the effectiveness of the foreign exchange interventions when the results from such an exercise are compared with those obtained from an event study analysis it is found that purchase based interventions seem to be successful especially after stabilization of the financial markets in that sense an asymmetry is detected regarding the effectiveness of interventions concerning the relationship between interest rates and exchange rates it is found that the uncovered interest rate parity condition operates in an unconventional way supporting the views put forward by recent emerging markets literature

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

job competition and the wage curve longhi s job competition and the wage curve regional studies the wage curve literature consistently finds a negative relationship between regional unemployment rates and regional wages the most widely accepted theoretical explanations interpret the unemployment rate as a measure of job competition this paper proposes new ways of measuring job competition alternative to the unemployment rate and finds that the negative relationship still holds when job competition is measured following the job search literature while for men the wage impact of the theoretically based measures of job competition is rather similar to the wage impact of the unemployment rate for women the difference is substantial longhi s la competition pour l emploi et la courbe des salaires regional studies la documentation sur la courbe des salaires affirme systematiquement que le taux de chomage regional est en correlation faible avec les salaires regionaux les explications theoriques les plus recues considerent le taux de

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

risk aversion foreign exchange speculation and gambler s ruin the apparent persistence of unexploited opportunities for expected profits in foreign exchange markets suggests highly risk averse market participants financial institutions put tight limits on the foreign exchange positions they may have at risk at any time despite beliefs that the odds are favourable that the positions will be profitable this safety first practice is consistent with keeping the probability of ruin low enough to be of no practical concern the setting of a very low probability of ruin for prudential reasons provides a rationale for traders behaving as if they have a degree of risk aversion that might otherwise seem implausibly high

foreign exchange intervention in emerging markets a survey of empirical studies nowadays foreign exchange interventions occur in emerging market economies whereas empirical studies on interventions mainly refer to advanced economies however interventions in emerging markets are different from those in advanced economies they occur regularly and central banks have considerable leverage derived from relatively high reserves some non sterilisation the central bank s information advantage and capital controls consequently these interventions often successfully impact the level and volatility of exchange rates nevertheless more research on interventions in emerging markets is needed analysing the influence of heterogeneous institutional circumstances examining the role of central bank communication and using high frequency data

job search by employed and unemployed youth analysis of data from the new youth cohort of the national longitudinal survey yields evidence that young unemployed job seekers chose higher levels of search effort as measured by number of methods used and time spent per method and lower reservation wages relative to offered wages than did comparable employed job seekers in 1981 these differences in search choices at least partly explain differences in search outcomes between the two groups unemployed searchers apparently were more likely than employed searchers to gain new employment and the wages they obtained were slightly lower the author argues that the greater search effort by unemployed job seekers is due to the higher costs of search they bear because of foregone earnings

how well can the new open economy macroeconomics explain the exchange rate and current account abstract this paper advances the new open economy macroeconomic literature in an empirical direction estimating and testing a two country model fit to u s and g7 data the model performs moderately well for the exchange rate and current account results offer guidance for future theoretical work parameter estimates lend support to the assumption of local currency pricing estimates are found for key parameters commonly calibrated in the theoretical literature such as the elasticity of substitution between home and foreign composite goods and the response of a country s risk premium to the net foreign asset position results also indicate that deviations from interest rate parity are not closely related to monetary policy shocks as recently hypothesized but that these deviations are strongly related to shifts in the current account

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

field experiments of discrimination in the market place controlled experiments using matched pairs of bogus transactors to test for discrimination in the marketplace have been conducted for over 30 years and have extended across 10 countries significant persistent and pervasive levels of discrimination have been found against non whites and women in labour housing and product markets rates of employment discrimination against non whites in excess of 25 have been measured in australia europe and north america a small number of experiments have also investigated employment discrimination against the disabled in britain and the netherlands and against older applicants in the united states

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

competition between employed and unemployed job applicants swedish evidence we use the swedish applicant database to investigate empirically whether being unemployed per se reduces the probability of getting contacted by a firm all searchers looking for a new job are invited to submit their personal details to this database over the internet since we have access to exactly the same information as the firms we can minimize the problems associated with unobserved heterogeneity our results show that an unemployed applicant faces a lower contact probability than an otherwise identical employed applicant thus supporting the notion that firms view employment status as a signal of productivity

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

special repo rates an empirical analysis duffie 1996 examines the theoretical impact of repo specials on the prices of treasury securities and concludes that all else the same an issue on special will carry a higher price than an otherwise identical issue we examine this hypothesis and find strong evidence in support of it we also examine whether the liquidity premium associated with on the run issues is due to repo specialness and find evidence of a distinct effect finally we investigate whether auction tightness and percentage awarded to dealers are related to subsequent specialness and find that both variables are generally significant underlying the cash market for u s treasury securities is the financing or repo market at any given time the repo rate for most treasury issues the general collateral rate is the same but a few issues are typically on special an issue on special has associated with it a repo rate that is less than the prevailing general collateral rate as a result the owner of a security that is on special is able to obtain below market financing rates via a repurchase agreement duffie 1996 examines the theoretical causes of repo specials and their impact on the prices of treasury securities in the context of a general equilibrium model his primary conclusion is that specialness will be priced in the cash market meaning that all else the same an issue on special or likely to go on special will carry a higher price than an otherwise identical issue we investigate this hypothesis using data on repo specials and find clear evidence in support of it we conclude that specialness is priced and that the magnitude of the cash market premium reflects both the future duration and magnitude of repo specialness we also examine whether the liquidity premium associated with on therun issues is due to repo specialness and find evidence of a distinct effect finally as a test of duffie s model we investigate whether auction tightness and percentage awarded to nonbank primary dealers are related to subsequent specialness the evidence is consistent with predictions with both variables generally significant

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

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

modeling the intensity of foreign exchange intervention activity abstract we suggest a count data model to study the intensity with which central banks conduct foreign exchange market intervention the application to the swiss interventions of the 1990s suggests that it yields important insight into the determinants of intervention policy

on the job search some empirical evidence from britain abstract this paper considers evidence from the labour force survey concerning job search by employed workers the unconditional probability of observing on the job search is decomposed into the product of two constituent probabilities upon which maximum likelihood estimation is performed the analysis facilitates the identification of who searches and whether search takes place in work or from unemployment temporary or part time employment encourages continued search by men but not women skilled workers search more than the unskilled and demonstrate a preference for employed search inter industry wage relativities encourage search on the job job tenure is a significant determinant of the quality of a job match and the subsequent likelihood that on the job search is undertaken employed job seekers adopt search strategies that are more readily integrated into a working environment

ranking unemployment duration and wages it explores the implication of one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time this assumption ranking is contrasted with the assumption of random hiring no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching the joint behaviour of unemployment the distribution of unemployment durations and wages are characterized the implication that the re employment prospects of employed workers were they to become unemployed are better than those of the currently unemployed appears to have been an important feature of european unemployment experience in the 1980 s this paper examines the effects of the composition of unemployment on wage determination it explores one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time we refer to this assumption as ranking and contrast it throughout to the assumption of random hiring or no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching we characterize the joint behaviour of unemployment the distribution of unemployment durations and wages ranking has a number of important implications first in addition to the obvious result that the exit rate from unemployment is a decreasing function of duration we show that the effect of duration is stronger the higher the rate of unemployment second with the wage depending on the distributions of prospective unemployment durations the presence of long term unemployed per se has little effect on wages third looking at the relation between the wage and the aggregate level of unemployment and comparing ranking to the case of no ranking the wage moves less with the level of unemployment but more with the change in unemployment put simply ranking and no ranking models show exactly the same aggregate unemployment slightly different long run responses of wages to unemployment and sharply different wage dynamics the paper is organized as follows section i characterizes the matching process and derives a matching function based on an urn ball process with vacancies as urns and applications by unemployed workers as balls thus the distribution of applications per vacancy depends on aggregate unemployment and vacancies vacancies with at least one acceptable application are filled when a vacancy receives more than one acceptable application firms use a rule to choose among applicants thus the rule determines who is hired but does not affect the number of hires section ii uses this matching function in a model of the labour market with continual job creation and destruction and characterizes the equilibrium values of unemployment vacancies and hires

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

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

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

the impact of unconventional monetary policy on the market for collateral the case of the french bond market we consider the channel consisting in transferring the credit risk associated with refinancing operations between financial institutions to market participants in particular we analyze liquidity and volatility premia on the french government debt securities market since these assets are used as collateral both in the open market operations of the ecb and on the interbank market in our time varying transition probability markov switching tvtp ms model we highlight the existence of two regimes in one of them which we refer to as the conventional regime monetary policy neutrality is verified in the other which we dub the unconventional regime monetary policy operations lead to volatility and liquidity premia on the collateral market the existence of these conventional and unconventional regimes highlights some asymmetries in the conduct of monetary policy

spanish treasury bond market liquidity and volatility pre and post european monetary union abstract spain enacted a number of important debt management initiatives in 1997 to prepare its treasury bond market for european monetary union we interpret the impacts of these changes through shifts in a bond liquidity life cycle function furthermore we highlight the importance of expected average future liquidity in explaining spanish bond liquidity premiums we also uncover pricing biases that support the spanish treasury s tactical decision to target high coupon premium bonds in its pre emu debt exchanges finally we show that emu has been associated with both a decrease in bond yield volatility and an increase in pricing efficiency

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

unemployment dynamics and duration dependence a major issue in the analysis of unemployment durations concerns distinguishing genuine duration dependence of the exit rate out of unemployment from unobserved heterogeneity we present a method for the nonparametric estimation of both phenomena designed to be applicable to time series data on aggregate outflows from different duration classes the model explicitly takes into account that individual exit rates are affected by the business cycle and by seasonal effects the method is applied to u s data we find diverging duration effects among black and white individuals however except for white males duration dependence is dominated by unobserved heterogeneity

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

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

improving incentives in unemployment insurance a review of recent research abstract this paper provides a review of the recent literature on how incentives in unemployment insurance can be improved we are particularly concerned with three instruments i e the duration of benefit payments or more generally the time sequencing of benefits monitoring in conjunction with sanctions and workfare our reading of the theoretical literature is that the case for imposing a penalty on less active job search is fairly solid a growing number of empirical studies including randomized experiments are in line with this conclusion
