day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

money supply announcements and interest rates another view in this paper i use a new approach to analyze the impact of money supply announcements on the bond market before 1980 the only available work on this subject consisted of a few unpublished papers by conrad 1978 sivesind 1978 and urich 1979 1 more recently published papers by grossman 1981 and urich and wachtel 1981 have appeared roley 1982 extends the grossman study to incorporate data after the federal reserve policy statement of october 6 1979 both grossman and urich and wachtel are primarily concerned with the question of money market efficiency using survey data made available by money market services of san francisco and data on treasury bill yields each finds that the market responds quickly to unanticipated changes in the money supply but that anticipated changes have no effect on interest rates in addition grossman finds that when he adds other variables such as past changes in the money

discount rate changes stock market returns volatility and trading volume evidence from intraday data and implications for market efficiency we examine the eaect of discount rate changes on stock market returns volatility and trading volume using intraday data equity returns generally respond negatively and significantly to the unexpected announcements however the eaect of expected changes on equity returns is insignificant furthermore our results indicate that equity prices respond to announcements within the trading period hour after the information release an indication of a return reversal is too small to cover the full transaction costs unexpected discount rate changes also contribute to higher market volatility although the volatility is short lived similarly unexpected changes in discount rates induce larger trading volume while expected changes do not abnormal trading volume occurs only in period t our results also support the notion that unexpected changes in the discount rates impact market returns irrespective of the federal reserve operating procedures 1999 elsevier science b v all rights reserved

macroannouncements bond auctions and rating actions in the european government bond spreads this paper investigates the impact of macroannouncements government bond auctions and rating actions on the 10 year government bond spreads for belgium france italy the netherlands spain with respect to germany using a unique tick by tick dataset over 1 02 2009 05 31 2012 we identify the impact of the three drivers via jump and cojump detection procedures disentangling the pre from the post announcement effects real economy and forward looking news releases from us and euro area country specific spanish and german macroannouncements and auctions hold in distressed countries such italy and spain have a statistically and economically significant effect no role is played by rating actions

monetary conditions and international investing we examine the relationship between monetary conditions and global stock returns previous studies established that u s stock returns during expansive u s monetary periods are significantly higher than returns during restrictive periods we found that this pattern prevails in non u s markets furthermore the pattern exists relative to both local and u s monetary conditions by examining several investment strategies we show that investors could have improved portfolio performance in the period studied by using both u s and local monetary conditions to guide their portfolio allocations using monetary conditions to determine portfolio composition would have been consistently beneficial throughout the past 30 years

the effects of macroeconomic news on high frequency exchange rate behavior this paper studies the high frequency reaction of the dem usd exchange rate to publicly announced macroeconomic information emanating from germany and the u s by us ing data sampled at a five minute frequency we are able to identify significant impacts of most announcements on the exchange rate change in the 15 minutes post announcement although the significance of these effects decreases rapidly as the interval over which the post announcement change in exchange rates is increased the direction of the exchange rate response conforms in general with a reaction function interpretation whereby reac tions to macroeconomic news are driven by the likely operations of monetary authorities in domestic money markets further we detect influences of german monetary policy deci sions on the reaction of the exchange rate and also differences between u s and german announcements in the exchange rate reaction time pattern i introduction this paper studies the high frequency reaction of the dem usd exchange rate to macroeconomic information emanating from germany and the u s specif ically we utilize exchange rate data covering the period 1 1 92 to 31 12 94 sam pled at a five minute frequency to investigate how the major monthly macroe conomic releases from these two countries impact the dem usd the infor mation contained in announcements over this three year period is extracted via a set of market expectation series supplied by money market services interna tional mms 1 our analysis improves on previous work in this area in two main respects first our study is conducted using very high frequency data whereas most earlier work has used exchange rate data sampled at a frequency of a number of hours or more this allows us to construct a very precise characterization of

the response of short term interest rates to weekly money announcements each friday at 4 10 p m est the federal reserve announces its estimate of the narrowly defined money stock for the statement week ending nine days previously these money announcements have become one of the main events in financial markcts if for no other reason than the fact that significant movements in interest rates have been associated with large unanticipated changes in the money stock moreover since the late 1970s interest rate fluctuations in response to money stock announcements have dramatically increased over the 1l 2 hour intervals spanning the weekly announcements for example the variance of the change in the threemonth treasury bill yield in the three years since october 1979 is more than thirty times larger than that of the previous two year period l two factors may account for a large portion of the increased volatility of shortterm interest rates first on october 6 1979 the federal reserve adopted a reserve aggregate approach to monetary control replacing a procedure that emphasized stability of short term yields second despite the greater emphasis placed on monetary control the variance of weekly announced changes in the money stock has risen by about 70 percent since late 1979 in turn if greater volatility of announced changes makes future changes more difficult to predict the volatility of unanticipated weekly changes in money would have also increased 2 thus if financial markets are efficient and if weekly money announcements contain relevant information larger unanticipated changes in money may have caused larger fluctuations in interest rates

rationality of negative stock price responses to strong economic activity monthly quarterly and annual data between 1956 and 1995 were used to examine the effects of real economic variables on stock returns future corporate cash flows and future inflation in general relative effects of various economic variables on stock returns are justified by their effects on future corporate cash flows and on inflation in particular employment growth shows the strongest negative effect on stock returns compared with other variables employment growth is related more negatively with future corporate cash flows and more positively with future inflation these effects are most pronounced in annual data which reflect long term relationships based on these results negative stock price responses to strong economic activity seem to be rational

stock prices and economic news this paper examines the daily response of stock prices to announcements about the money supply inflation real economic activity and the discountrate except for the discount rate survey data on market participants expectations of these announcements are used to identify the unexpected component of the announcements in order to test the efficient markets hypothesis that only the unexpected part of any announcement the surprise moves stock prices the empirical results support this hypothesis and indicate further that surprises related to monetary policy significantly affect stock prices there is only limited evidence of an impact from inflation surprises and no evidence of an impact from real activity surprises on the announcement days there is also only weak evidence of stock price responses to surprises beyond the announcement day this abstract was borrowed from another version of this item

the reaction of stock prices to unanticipated changes in money a note much of the past work on the money stock market relationship centered on the question of whether money is a leading indicator of stock prices studies by sprinkel 22 homa and jaffee 10 and hamburger and kochin 8 supported the view that past increases in money lead to increases in equity prices the implication of this work was that investors could earn above normal proflts by using a trading strategy based on the observed behavior of the money stock this contradicts the efficient markets hypothesis which asserts that current asset prices reflect all available information so that no such trading strategy can exist subsequent research by cooper 3 pesando 17 rozeff 21 and rogalski and vinso 19 has shown that past money changes do not contain predictive information on stock prices upholding the efficient markets view this paper investigates whether the response of common stock prices to weekly money announcements is consistent with the efflcient markets hypothesis unlike the above research therefore the focus is on the very short run response of stock prices to both anticipated and unanticipated announced changes in money recent work by berkman 1 grossman 7 urich and wachtel 25 and roley 20 indicates that short term interest rates respond only to the unexpected component of the announcement with short term rates rising when the announced change in money exceeds the expected change berkman also examined the reaction of stock prices finding that an unanticipated increase in the money supply depressed share prices lynge 13 found that positive money announcements lowered stock prices but since he did not distinguish expected from unexpected money growth his results do not bear directly on the efficient markets issue in investigating the response of stock prices to weekly money announcements survey data on market participants forecasts of the announced weekly change

events that shook the market tick data on the standard and poor s 500 stock index s p 500 futures contract and newswire searches are used to match events to large 1 to 5 minute stock price changes sixty nine events that led to large stock price changes are identified between 1982 and 1999 53 of which are directly or indirectly related to monetary policy many large stock price changes have no events associated with them

macroeconomic news announcements and stock market jump intensity dynamics abstract this paper examines the effect of macroeconomic releases on stock market volatility through a poisson gaussian garch process with time varying jump intensity which is allowed to respond to such information the day of the announcement per se is found to have little impact on jump intensities employment releases are an exception however when macroeconomic surprises are considered inflation shocks show persistent effects while monetary policy and employment shocks reveal only short lived effects also the jump intensity responds asymmetrically to macroeconomic shocks evidence on macroeconomic variables relevance in explaining jump dynamics and improving volatility forecasts on event days is provided

asset returns discount rate changes and market efficiency the primary purpose of this paper is to reconcile the previous findings of discount rate endogeneity with the presence of discount rate announcement effects in securities markets the crux of this reconciliation is the distinction between technical discount rate changes that are endogenous and nontechnical changes which contain some informative policy implications in essence we attempt to separate expected discount rate changes from unexpected changes or equivalently the expected component of discount rate changes from the unexpected component if markets are efficient the former should have no announcement effects while the latter may be associated with an announcement effect accordingly the focus of the empirical analysis is on the interaction between discount rate exogeneity the specific monetary policy regime and accouncement effects in addition we examine whether the behavior of these markets in the postannouncement period is consistent with the rapid price adjustment implied by market efficiency

price as a stimulus to think the case for willful overpricing consumers aware of a new benefit will often experience uncertainty about its personal relevance or usage value this paper shows that the decision to deliberate further to resolve this uncertainty and reach a polarized judgment of personal relevance critically depends on the posted price in particular a price above the consumer s initial willingness to pay might be thought provoking and enhance the perception of relevance with a certain probability this behavioral mechanism is introduced formally and by way of an experiment with reference to the purchase of organic lettuce and fair trade coffee accounting for the effect of price as a stimulus to think a monopolistic firm should either over price transgressive pricing or under price regressive pricing in comparison to the consumer s willingness to pay under certain circumstances the firm should also empower consumers with means that reduce the effort of deliberation

stock prices and the effective exchange rate of the dollar the literature on the relation between stock prices and exchange rates is very poor and includes few studies that have argued that exchange rate changes do effect stock prices by relying on the portfolio approach to exchange rate determination it is argued that a change in stock prices could also have an impact on exchange rates i e there could be a two way relationship between exchange rates and stock prices granger concept of causality as well as cointegration technique are employed to support this conjecture the empirical results show that there is bidirectional causality between stock prices measured by s p 500 index and the effective exchange rate of the dollar at least in the short run the cointegration analysis reveals that there is no long run relationship between two variables

market response to the weekly money supply announcements in the 1970s the hypothesis that the weekly announcement of the money supply affects interest rates is examined the announcement effect is interpreted as a policy anticipation effect that is an unanticipated increase in the money supply leads to an increase in interest rates in anticipation of future tightening by the federal reserve estimates of this effect with proxies for the unanticipated change constructed from a survey of money supply forecasts and an arima model indicate that a financial markets respond very quickly to the announcement and b the response was largest when policymakers emphasized the importance of the monetary aggregates financial market participants are careful observers of the weekly money supply announcement and generally agree that the announcement often leads to changes in interest rates this occurs because the announcement leads market participants to revise their expectations both of future federal reserve policy actions and of future economic conditions in this paper we examine the response of yields on treasury bills to the announcement of the money supply and the extent to which that response has varied in the last ten years money supply announcements may affect market interest rates in three ways first actual expansion of the money supply leads to lower interest rates through a liquidity effect however rapid monetary growth which is not anticipated leads market participants to expect the federal reserve to counteract such growth in the future as a consequence there may be a policy anticipation effect which causes higher interest rates in anticipation of future tightening furthermore prolonged rapid monetary growth also creates inflation and inflationary expectations which lead to higher interest rates thus there may exist a third effect the inflationary expectations effect which also leads to higher interest rates our interest in this paper is in the immediate market response to the weekly announcement of the money supply which as we argue below is most likely to be a policy anticipation effect the policy anticipation effect is best described by example suppose that the announced change in the money supply exceeds that which was expected by

risk inflation and the stock market most explanations for the decline in share values over the past two decades have focused on the concurrent increase in inflation this paper considers an alternative explanation a substantial increase in the riskiness of capital investments we show that the variance of firms real gross marginal return on capital has increased significantly increasing the relative riskiness of investors returns on equity and that this can explain a large part of the market decline we also assess the effects of increase in the mean and variance of the inflation rate and a decline in firms expected return on capital this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

the adjustment of stock prices to information about inflation this paper analyzes the reaction of stock prices to the new information about inflation based on daily returns to the standard and poor s composite portfolio from 1953 78 it seems that the stock market reacts negatively to the announcement of unexpected inflation in the consumer price index c p i although the magnitude of the reaction is small it is interesting to note that the stock market seems to react at the time of announcement of the c p i approximately one month after the price data are collected by the bureau of labor statistics

economic news and equity market linkages between the u s and u k abstract the source of equity market linkages between the u s and u k is investigated by focusing on intraday price movements of stock index futures contracts we document heightened u k return volatility at 11 30 a m and 1 30 p m gmt which corresponds to regular macroeconomic releases in the u k and u s respectively the response of u k equities in the half hour surrounding the u s announcements is significant and similar to price movements for u s equities to the same announcements these results support the hypothesis that the documented international equity market linkages are attributable to reactions of foreign traders to public information originating from the u s

the changing influence of money and monetary policy on exchange rates foreign exchange dealers said the american currency got an additional boost after the federal reserve reported that the nation s money supply rose 700 million in the latest week a development that is likely to put upward pressure on interest rates most economists had been expecting a decline in the money supply figures the wall street journal 25 january 1982 14 i introduction the importance of the linkage between money and asset prices such as interest rates and exchange rates is now well understood friedman 1990 12 writes given the familiar dependence of imports and exports on real exchange rates together with the dollar s evident relationship to interest rates the combination of a larger foreign sector in the u s economy and flexible exchange rates has clearly opened new avenues for monetary policy to affect economic activity however the precise nature of the relationship between money and exchange rates has long been a topic for research in international economics with the adoption of a system of floating exchange rates by most of the industrialized countries in march 1973 and the development of the rational expectations efficient markets hypotheses attempts to model observed fluctuations in exchange rates have focused on incorporating the important role of expectations of particular interest to the research in this paper is the dornbusch 1976 overshooting model which provided the structural foundation for the work of engel and frankel 1984 in the money announcements literature in the money announcements literature researchers employed unanticipated money announcements defined as the difference between announced and expected m1 to examine the linkage between money and asset prices as hakkio and pearce 1985 point out the research on foreign exchange rates in this laboratory was motivated by mussa s 1979 empirical findings in support of the efficient markets theory i e changes in exchange rates are unpredictable and are largely the result of the impact of new information on expectations in this literature researchers commonly regressed changes in the exchange rate on unanticipated money over sample periods which coincided with different policy regimes at the federal reserve to determine if the coefficient on unanticipated money say b sub 1 varied from one policy regime to another overall their findings uncover a significant link between unanticipated money and exchange rates and the size sign and significance of b sub 1 varies from one sample period to another 1 while suggestive the apparent link between changes in b sub 1 and changes in fed policy regimes is difficult to evaluate absent a model which formally incorporates such a link 2 thus my objective in this paper is to develop a basic theoretical empirical link between fluctuations in b sub 1 and changes in fed policy regimes i begin by extending the important work of engel and frankel 1984 in section ii to incorporate a policy feedback parameter g sub 1 in the money supply process which will represent the rational expectation of the type of monetary control regime in place at the federal reserve at the time of a money announcement it is shown that the magnitude of the response of exchange rates to an unanticipated announcement is mainly driven by agents expectations of the federal reserve s response to the deviation of the actual money supply from a pre specified target in section iii the time varying response of the dollar german mark exchange rate to weekly unanticipated money announcements b sub 1t and the time varying policy feedback parameter g sub 1t which reflects the adjustment of the federal funds rate to money away from target are estimated on a weekly basis using these estimates the variation of the coefficient b sub 1t vis a vis the changes in g sub 1t is examined over the january 1978 to december 1982 sample period the results provide considerable support for the hypothesized link between parameters b

what do chinese macro announcements tell us about the world economy we examine the effect of scheduled macroeconomic announcements made by china on world financial and commodity futures markets all announcements related to chinese manufacturing and industrial output move stock markets energy and industrial commodities as well as commodity currencies news about chinese domestic consumption leaves most markets unaffected suggesting that market participants view the announcements primarily as a signal of the state of the global economy rather than merely of china s domestic demand the market response to unexpectedly strong output announcements is not consistent with investors being concerned about tightening of chinese macroeconomic policy instead the world markets view strong chinese output as a rising tide that lifts all boats jel classification e44 g14 g15

is there news in the prime rate using intraday data we find that bank announcements of changes in the prime rate have significant effects on dow jones stock price indexes and yields in the treasury bill futures market we find comparable effects using daily data for indexes of share prices of banks and financial firms as well as interest rates on various maturities of government securities our evidence is consistent with the view that banks have a comparative advantage in processing private information gained through bank borrower relations and the regulatory supervision process

transmission of shocks and contagion from u s to mena equity markets the role of oil and gas markets abstract using a multifactor model augmented with oil and gas returns this paper examines contagion from the us to mena equity markets and studies the role of energy price fluctuations in amplifying the dependence between the us and mena equity markets we provide empirical evidence of a strong contagion effect originating from the us to mena equity markets the regional oil and gas factors account for the bulk of the variance of the mena equity returns and our findings suggest that the oil and gas markets play an important role in strengthening the dependence between the mena and us markets during episodes of market turmoil we discuss the policymaking importance of our results and propose a strategy to curb the adverse effects of us return shocks on mena equity markets during episodes of stress

the impact of macroeconomic surprises on spot and forward foreign exchange markets abstract this paper evaluates the effects of surprises in 23 types of macroeconomic announcements on foreign exchange rates and on the forward premium several findings emerge first as in the balance of payment framework announcements that convey a decline in consumer demand increase foreign exchange rates second the ppp hypothesis is rejected in favor of portfolio balance effects in determining exchange rates third the behavior of forward premiums is consistent with covered interest rate parity fourth exchange rates respond to announcements related to consumer demand inflation and interest rates but not to the announcements directly related to the general strength of the economy finally among the news releases considered surprises in the treasury budget trade balance and capacity utilization have the strongest influence in the currency market
