rockets and feathers understanding asymmetric pricing prices rise like rockets but fall like feathers this stylized fact of most markets is con rmed by many empirical studies in this paper i develop a model with competitive rms and rational partially informed consumers where such asymmetric response to costs by rms emerges naturally in contrast to public opinion and past work collusion is not necessary to explain such result using a rich dataset of retail gasoline prices i nd the observed price dispersion pattern to be consistent with the model s prediction

exchange rates interest rates and current account news some evidence from australia abstract this paper investigates the effects of the australian current account news on exchange rates and interest rates for the period july 1985 to december 1992 the results indicate that the australian dollar depreciated and interest rates rose as a result of an announcement of a larger than expected current account deficit this is consistent with the view that market participants expected a foreign exchange market intervention sale of the australian dollar by the reserve bank of australia and they used the portfolio balance model of exchange rate determination when responding to the news in addition significant structural breaks were found and the analysis shows that after january 1990 the news affected neither exchange rates nor interest rates

gasoline price volatility and the elasticity of demand for gasoline abstract we examine how gasoline price volatility impacts consumers price elasticity of demand for gasoline results show that volatility in prices decreases consumer demand for gasoline in the intermediate run we also find that consumers appear to be less elastic in response to changes in gasoline price when gasoline price volatility is medium or high compared to when it is low moreover we find that when we control for variance in our econometric model gasoline price elasticity of demand is lower in magnitude in the long run

temporary wholesale gasoline price spikes have long lasting retail effects the aftermath of hurricane rita abstract i study u s gasoline prices following hurricane rita to show that short lived geographical differences in the severity of wholesale gasoline price spikes are associated with long lasting geographical differences in retail prices in most u s cities wholesale prices spiked significantly for roughly 2 weeks following the hurricane however in cities where this spike was particularly large retail margins remained higher than in other cities for nearly 2 months high retail margins dissipated more quickly after the hurricane in cities where competition between stations tends to generate cyclical retail price fluctuations independent of wholesale cost movements i discuss why prices may have fallen faster in cities exhibiting retail price cycles and present additional results identifying differences in market characteristics between cities with and without price cycles i find that cycling cities tend to have higher population density and have independent nonrefinery brand stations that are mor

every minute counts in financial markets abstract this paper represents an introductory study of ultra high frequency minuute by minute data for forex spot rates bid ask reuters quotes on three days autumn 1987 the frequency of price revision size of spread and statistical characteristics are measured the series exhibit time varying leptokurtosis unit roots and first order negative correlation the latter especially in disturbed jumpy markets the effect of time aggregation on these characteristics is examined and variance ratios are analyzed multivariate analysis revealed significant relationships between lagged exchange rates both the own rate and the key deutsche mark us dollar rate and the current spot rate

why interest rates react to money announcements an explanation from the foreign exchange market abstract when the fed announces a money supply greater than had been expected interest rates rise why one explanation is that the market raises its estimate of the future rates of money growth and inflation and bids up nominal interest rates we offer contrary evidence on such days the dollar appreciates not depreciates an alternative explanation is that the market perceives the change in the money stock as a transitory fluctuation that the fed will reverse in the future the anticipated future tightening raises today s real interest rate causes a capital inflow and appreciates the dollar the result in fact observed

enhancing market power by reducing switching costs a proportional decrease in switching costs increases competition and social welfare however a lump sum decrease in switching costs softens competition and does not invariably increase social welfare

the use of flow analysis in foreign exchange exploratory evidence abstract this paper provides questionnaire evidence on the role of flow analysis for professional traders and fund managers this evidence suggests that besides fundamental information and technical analysis the analysis of flows provides an independent third type of information for professionals the view that flows can be used to learn about fundamentals is not consistent with the data instead evidence indicates that flows more likely provide insight into semi fundamental private information

economic news exchange rates and interest rates the paper esamines the post october 1979 response of exchange rates and interest rates to the new information contained in the first announcement of fifteen us macroeconomic series illarkets respond primarily to monetary news but also to news about the trade deficit domestic inflation and variables that reflect the state of the business cycle for all fifteen macroeconomic variables an increase decrease in interest rates is accompanied by an appreciation depreciation of the dollar which is consistent with models that stress price rigidity and absence of purchasing power parity the effect of economic news on asset prices has received increasing attention in the economic literature because an outcome of the efficient markets rational expectations hypothesis is that flesible asset prices change the moment new information about future fundamentals arrives in the market in the exchange rate literature the role of news has gained importance because structural models have failed to predict most of the variation in exchange rates during the 1970s see imeese and rogoff 1983 researchers were naturally led to investigate the types of news that make exchange rates so volatile and to utilize news in order to test which model of exchange rate determination is consistent with the floating eschange rate experience notable studies are those of dornbusch 1980 frenkel 1981 edwards 1982a b 1983 copeland 1984 and rose 1984 in this paper i also examine the effects of macroeconomic news on eschange rates but i adopt a different more direct strategy one that complements previous work avoids some of its shortcomings and promises interesting conclusions i examine the instantaneous response of exchange rates the moment a piece of economic news hits the market if one can isolate the exact time during a business day when news arrives it is straightforward to examine the response of exchange rates because financial data are continuously available the advantages of the present methodology are many first it is possible to identify the exact types of economic news and how they affect exchange rates second the simultaneity bias which plagues the previous literature on exchange rates and news is not present here the independent variables that represent news can be interpreted as causal the paper was presented at the 1985 meeting ofthe american economic association the author wishes to thank sebastian edwards r w hafer nicholas karamouzis andrew rose and two anonymous referees for helpful comments kim rupert of the money market services for providing the survey data soo kounne for able research assistance and barnard college for research support

one minute in the life of the dm us public news in an electronic market abstract public news can be expected to change market prices but unlike public information there are differing expectations about the impact hence trading is necessary for the market to process these divergent views a surprise announcement of an increase in german interest rates coupled with concurrent transactions data enables us to study in detail dealers reactions the patterns observed are consistent with dealers practice to book targeted profits immediately if possible in the face of uncertainty evidence also shows that the speculative activity by traders in initial reaction to the news destabilized the market for the next 2 h

the influence of fundamentals on exchange rates findings from analyses of news effects as we survey the literature of macroeconomic news in the foreign exchange market we can by now look back on nearly 30 years of research the first studies which analysed news effects on exchange rates were established in the early 1990s see for example dornbusch almost at the same time meese and rogoff published their influential paper revealing the forecasting inferiority in exchange rates of structural models against the random walk this finding has shocked the pillars of exchange rate economics and thus cast general suspicion on research focusing on fundamentals in this field the eventual rising popularity of event studies can partly be attributed to the re establishment of the raison d etre of exchange rate economics this work focuses on systematically surveying this literature with particular respect to its primary goal i e shedding light on the analytical value of fundamental research thus its major findings are first fundamental news does matter whereas non fundamental news matters to a lesser degree second news influences exchange rates via two separated channels i e incorporating common information into prices directly or indirectly based upon order flow third with a few exceptions the impact of fundamental news on exchange rates is fairly stable over time

managing the dollar has the plaza agreement mattered this paper considers whether the plaza agreement of september 1985 marked the beginning of a fundamental shift in the exchange rate policy regime for the united states the former west germany and japan the paper uses a simple monetary model of the open economy to illustrate how the exchange rate responses to news about the trade balance when the government authorities gear policy toward resolving external imbalances the paper finds that u s dollars exchange rates against the japanese yen and the west german mark respond strongly to news about the u s trade deficit during the period following the plaza agreement but not during the period preceding the agreement this evidence evaluated in the context of the simple model suggests that the plaza agreement marked a significant shift toward more active government management of exchange rates copyright 1991 by ohio state university press

testing for news in foreign exchange markets abstract traditional tests of the role of interest rate news on foreign exchange rates are analysed and found to be of little empirical value

news shocks in the data olympic games and their macroeconomic effects we examine the macroeconomic effects of bidding for the olympic games using panel data for 188 countries during the period 1950 2009 our findings confirm that economies react to news shocks investment consumption and output significantly increase 9 to 7 years before the actual event in bidding countries hosting countries also experience significant increases in investment consumption and output 5 to 2 years before the hosting of the games mapping the olympics into a macroeconomic model we show that we can match our empirical findings if we assume that an olympic bid represents news about increases in government investment

elasticities of demand for gasoline in canada and the united states abstract fluctuations in the world price of oil the concern with greenhouse gas emissions and the efforts to revive the 1997 kyoto protocol have resulted in renewed interest in the estimation of elasticities of demand for gasoline in this paper a complete system of demand equations is estimated including an equation for the demand for gasoline canadian family expenditure famex and united states consumer expenditure cex survey data are used household level data permits estimation of elasticities for various household groups also differences in demand responsiveness to own price and income changes are estimated for different regions in canada and the united states demand is found to be own price and income inelastic on the whole as reported in earlier studies there is also variation in these elasticities across regions of canada and the united states however larger differences are observed with respect to household size and housing tenure than to region of residence

news effects in a high frequency model of the sterling dollar exchange rate this paper uses an extremely high frequency data set on the dollar sterllng exchange rate to investigate the impact of news events on the very short term movements in exchange rates the data set is a continuous record of the quoted price for the exchange rate on the reuters screen as such it records some 130 000 observations over an 8 week period the paper investigates the time series properties of the data using orthodox regression models and then by making allowance for a time varying conditional variance the conclusions vary significantly in moving to this more sophisticated model the exercises are repeated now incorporating news announcement effects letting these affect the level of the exchange rate and then the conditional variance process again it is found that the conclusions are radically altered in moving to the increasingly sophisticated model

us money announcements and covered interest parity the case of japan abstract this paper examines the effects of us money announcements on dollar and yen denominated securities in their respective onshore markets the effects are consdered over several periods corresponding to possible us and japanese policy regimes the consistency of the responses is further examined by testing whether the responses of dollar denominated securities yen denominated securities the spot yen dollar exchange rate and the forward yen dollar exchange rate violate covered interest parity given the results of previous studies the evidence suggests that restrictions on capital mobility in japan have not allowed complete international integration of japanese financial markets

can information heterogeneity explain the exchange rate determination puzzle empirical evidence shows that most exchange rate volatility at short to medium horizons is related to order flow and not to macroeconomic variables we introduce symmetric information dispersion about future macroeconomic fundamentals in a dynamic rational expectations model in order to explain these stylized facts consistent with the evidence the model implies that a observed fundamentals account for little of exchange rate volatility in the short to medium run b over long horizons the exchange rate is closely related to observed fundamentals c exchange rate changes are a weak predictor of future fundamentals and d the exchange rate is closely related to order flow

international market response to announcements of us macroeconomic data abstract this paper presents empirical evidence relating the announcement effects of us money supply and inflation cpi and ppi to eurocurrency interest rates and the foreign currency markets both spot and forward for seven industrial countries over the period 1977 1982 the results indicate that unanticipated components of announced changes in money supply have a significant positive effect on eurocurrency interest rates and a negative effect implying dollar appreciation on the spot exchange rates unanticipated changes in ppi have a positive significant effect on interest rates a small surprisingly negative impact on spot exchange rates and a positive effect on gold prices the cpi has no effect on either market

consumer search and dynamic price dispersion an application to gasoline markets this article studies the role of imperfect information in explaining price dispersion we use a new panel data set on the u s retail gasoline industry and propose a new test of temporal price dispersion to establish the importance of consumer search we show that price rankings vary significantly over time however they are more stable among stations at the same street intersection weestablishtheequilibriumrelationshipsbetweenpricedispersionandkeyvariables from consumer search models price dispersion increases with the number of firms in the market decreases with the production cost and increases with search costs

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

representativeness of news and exchange rate dynamics abstract guided by psychological evidence we develop a behavioral exchange rate model in which investors perception of fundamental shocks switches between two states according to the representativeness heuristic agents underestimate the informational content of news in calm periods whereas they overreact to news if they encounter a series of distinct exchange rate changes simulations indicate that the model mimics the behavior of actual exchange rates quite well for instance we observe fat tails for the distribution of the returns and volatility clustering

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

what defines news in foreign exchange markets abstract this paper examines whether the traditional sets of macro surprises that most of the literature considers are the only sorts of news that can explain exchange rate movements we examine the intra daily influence of a broad set of news reports including variables which are not typically considered fundamentals in the context of standard models of exchange rate determination and ask whether they too help predict exchange rate behavior we also examine whether news not only impacts exchange rates directly but also influences exchange rates via order flow signed trade volume our results indicate that along with the standard fundamentals both non fundamental news and order flow matter suggesting that future models of exchange rate determination ought to include all three types of explanatory variables

the environmental and economic impact of the carbon tax in australia to fulfil its emission reduction target pledged in the copenhagen accord the australian government has determined to introduce a carbon tax from july 1st 2012 this paper simulates the effects on the environment and on the economy of a carbon tax of a 23 per tonne of carbon dioxide proposed by the government with and without a compensation policy we employ a computable general equilibrium model with an environmentally extended social accounting matrix according to the simulation results the carbon tax can cut emissions effectively but will cause a mild economic contraction because the price signal is intact the proposed compensation plan has little impact on emission cuts while significantly mitigating the negative effect of a carbon tax on the economy

the foreign exchange market a random walk with a dragging anchor this paper explores some anomalies in the foreign exchange market it is hard to find evidence of either short term overshooting or of longer term reversion to an equilibrium the forward exchange rate contains virtually no information on future spot rates discussions with practitioners indicate that longer term speculation based on fundamentals is strictly limited and survey data and other evidence suggest that expectations and speculation are based on a variety of models the interplay between speculation based on fundamentals and on a random walk or chartist approach influences the outcome this endorses the prior model of j a frankel and k a froot copyright 1988 by the london school of economics and political science

the price and welfare effects of biofuel mandates and subsidies the coordination of agricultural environmental and energy policies requires a thorough understanding of the interactions between crop food and energy markets this paper develops a general equilibrium model to analyze the interactions and to evaluate the price and welfare effect of biofuel mandates and subsidies results suggest that biofuel mandates are a primary cause of some of the major concerns associated with crop based biofuel production including higher food prices and lower consumer welfare the price and welfare effects of biofuel subsidies depend on the level of the biofuel mandate when the mandate is weak or not binding a biofuel subsidy becomes a transfer from consumers to biofuel producers which tends to reduce food and fuel prices because of the negative income effect however with a strong mandate a biofuel subsidy will increase the prices of crops food and fuel when crops account for a large share of production cost and when the supply of crops is inelastic using parameter values consistent with empirical evidence found in the u s we calculated the price and welfare effects of the biofuel mandates and subsidies specified in the energy independence and security act of 2007 results suggest that the biofuel mandates and subsidies increased the price of corn by 25 40 increased the price of food by 1 5 2 5 and lowered the price of gasoline by 5 10 overall the biofuel policies had only a small effect on consumer utility

exchange rates and news a multi currency approach abstract in this paper a multi currency model is used to investigate the relationship between spot exchange rates forward rates market efficiency and new information it is shown that in a world with more than two countries the error term in the standard market efficiency tests will be correlated across rates it is also shown that the exchange rate can be expressed as a function of factors known in advance which are captured by the forward rate determined in the previous period and news the empirical results presented in the paper tend to support the model s implications

fx trading and exchange rate dynamics i examine the sources of exchange rate dynamics by focusing on the information structure of fx trading this structure permits the existence of an equilibrium distribution of transaction prices at a point in time i develop and estimate a model of the price distribution using data from the deutsche mark dollar market that prroduces two striking results 1 much of the short term volatility in exchange rates comes from sampling the heterogeneous trading decisions of dealers in a distribution that under normal market conditions changes comparatively slowly 2 public news is rarely the predominant source of exchange rate movements over any horizon copyright the american finance association 2002

more evidence on the dollar risk premium in the foreign exchange market in this article we develop and estimate an econometric panel data model to capture the common dynamics in dollar risk premia in various forward foreign exchange rates the common component in the dollar risk premium is highly significant and embodies a common pattern of positive serial correlation persistence for the pound the yen and the mark interestingly our results indicate that the dynamics of the forward prediction error can be attributed almost exclusively to this dollar related common component our evidence also suggests that the three different foreign currencies dollar risk premia respond to the common factor to different degrees

news from the u s and japan which moves the yen dollar exchange rate abstract intra daily movements in the yen dollar exchange rate are examined in four non overlapping segments within each business day from january 1980 to september 1985 the results indicate that the dollar tended to appreciate in the new york segment and depreciate in the european segment in three of the four subsamples considered the tokyo segment made virtually no contribution to annual yen dollar rate movements the volatility of the exchange rate also differed across markets finally in examining the relative effects of news from the u s and japan explicitly u s money announcement surprises had the most consistent effects

the short run dynamics of the price adjustment to new information we examine how prices in interest rate and foreign exchange futures markets adjust to the new information contained in scheduled macroeconomic news releases in the very short run using 10 second returns and tick by tick data we find that prices adjust in a series of numerous small but rapid price changes that begin within 10 seconds of the news release and are basically completed within 40 seconds of the release there is some evidence that prices overreact in the first 40 seconds but that this is corrected in the second or third minute after the release while volatility tends to be higher than normal just before the news release there is no evidence of information leakage in our analysis we correct for the biases created by bid ask spreads and tick by tick data

deutsche mark dollar volatility intraday activity patterns macroeconomic announcements and longer run dependencies this paper provides a detailed characterization of the volatility in the deutsche mark dollar foreign exchange market using an annual sample of five minute returns the approach captures the intraday activity patterns the macroeconomic announcements and the volatility persistence arch known from daily returns the different features are separately quantified and shown to account for a substantial fraction of return variability both at the intraday and daily level the implications of the results for the interpretation of the fundamental driving forces behind the volatility process is also discussed the efficient market hypothesis contends that financial asset prices provide rational assessments of fundamental values and future payoffs by implication price changes should reflect the arrival and processing of all relevant new information however the proportion of return variability that can be ascribed to public news announcements is low for example cutler poterba and summers 1989 find that even the largest daily price changes in the stock market generally cannot be associated with any significant economic news 1 moreover proxies for the flow of public information e g the number of news items released by reuter s news service berry and hiowe 1994 or dow jones company mitchell and mulherin 1994 explain little of the overall variation thus if private information is ruled out proponents of rational price formation have to assert the existence of important news items

domestic and international financial market responses to federal deficit announcements abstract this study examines the response of domestic and international financial variables to announced changes in federal deficit projections over the 1981 1994 period as observed in earlier studies rates on us treasury securities responded positively to announced increases in federal deficit projections new evidence shows that deficit effects are transmitted internationally with foreign long term interest rates also increasing in response to announced increases in us deficit projections the exchange value of the dollar tends to be positively related to announced changes in deficit projections but that result appears to be related to the degree of insulation of foreign financial markets from us financial markets finally the price of gold responded positively to announced changes in deficit projections taken together the results suggest that higher projected deficits raise real interest rates in part because of an increase in an inflation risk premium

exchange rate variability and monetary policy under rational expectations some euro american experience 1973 1979 abstract we analyze the sources of changes in nominal and real rates of exchange between six european currencies and the u s dollar we conclude that over the period 1973 1979 unexpected changes in the price of oil together with unanticipated monetary shocks at home or in the u s were the most important causes of changes in exchange rates a multi state kalman filter technique is used to compute empirical proxies for unanticipated changes in the exogenous variables since both oil price shocks and changes in u s monetary trends effect the european currencies in different degrees it follows that differential domestic rates of inflation are not the only reason why arrangements to restrict exchange rate fluctuations such as the european monetary system may run into trouble

exchange rates and fundamentals new evidence from real time data abstract this paper analyses the link between economic fundamentals and exchange rates by investigating the importance of real time data we find that economic news in the united states germany and the euro area have been a driving force behind daily us dollar euro dem exchange rate developments in the period 1993 2003 the larger importance of us macroeconomic news is at least partly explained by their earlier release time compared to corresponding german and euro area news the exchange rate is also shown to respond more strongly to news in periods of large market uncertainty and when negative or large shocks occur overall the model based on real time data explains about 75 of the monthly directional changes of the us dollar euro exchange rate although it does not explain well the magnitude of the exchange rate changes

the impact of news and alternative theories of exchange rate determination over the last decade two of the more important developments in the area of exchange rate determination are the construction of the asset market model and the recognition that news is a key factor affecting exchange rates the asset market model has evolved as an alternative to the traditional flow model of exchange rate determination in contrast to the flow model where the exchange rate is determined by the flow demand for and flow supply of foreign exchange exchange rates adjust to allocate the total stock of foreign exchange in question in the asset market model this model may be presented in one of two forms the monetary approach or the portfolio balance approach the former is summarized in the work of bilson 1978a dornbusch 1976 frenkel 1976 johnson 1976 and mussa 1976 1979 while the latter stems from the efforts of branson 1981 branson halttunen and masson 1977 dooley and isard 1982 kouri 1976 kouri and de macedo 1978 and rodriguez 1980 while the logical consistency of these models has enhanced their popularity empirical support has been limited the importance of unanticipated shocks or news in explaining exchange rate behavior has been suggested by dornbusch 1980 frenkel 1981 isard 1983 and mussa 1979 the basis for this suggestion is the efelcient markets approach that suggests securities prices in a capital market should reflect all available information therefore the predominant cause of exchange rate movements is news that could

how markets process information news releases and volatility we examine the impact of scheduled macroeconomic news announcements on interest rate and foreign exchange futures markets we find these announcements are responsible for most of the observed time of day and day of the week volatility patterns in these markets while the bulk of the price adjustment to a major announcement occurs within the first minute volatility remains substantially higher than normal for roughly fifteen minutes and slightly elevated for several hours nonetheless these subsequent price adjustments are basically independent of the first minute s return we identify those announcements with the greatest impact on these markets we examine the impact on interest rate and foreign exchange markets of scheduled macroeconomic news releases such as the employment report the consumer price index cpi and the producer price index ppi many market participants believe that such announcements have a major impact on financial markets indeed a small industry devoted to predicting the figures to be released in upcoming releases has evolved in recent years with the exception of the weekly money supply figures however the impact of such announcements on financial markets has received scant attention 1 this is doubly surprising given the considerable research interest in market volatility since these news releases are a potential source of much of this volatility consider for instance figure 1 as shown there prices in interest rate and foreign exchange futures markets are much more volatile between 8 30 and 8 35 a m eastern time et than during any other five minute trading period including

shock effects on stocks bonds and exchange rates abstract tick data and newswire searches are used to find events that led to large and rapid price changes in a stock future a bond future and three exchange rate futures knowledge of these events may be useful in future work they have the advantages that they are truly surprises and that the sign of their effect on each financial instrument is known the events are used in this study to analyze the effects of three types of events monetary price and real on the five instruments

do exchange rates respond to day to day changes in monetary policy expectations when no monetary policy changes occur this paper addresses whether exchange rates respond to changes in expectations of future u s monetary policy when no actual monetary policy changes occur we employ data on federal funds futures contracts for extracting a measure of policy expectations control for the surprise element of macroeconomic news and policy developments and analyze more than 12 years of daily exchange rate data our findings show that continuous day to day changes in expectations of future monetary policy are associated in a highly significant and systematic way with day to day changes in exchange rates even when no actual monetary policy changes occur this suggests that monetary policy matters for daily exchange rate determination in more ways than merely through infrequent actual policy changes

on the biasedness of forward foreign exchange rates irrationality or risk premia in this article the authors reconsider the k a froot and j a frankel 1989 results on the sources of forward discount bias they question the economic validity of some estimation restrictions that they impose and thus are led to question some of their results the authors employ a new exchange rate survey database that includes european monetary system currencies and use univariate and pooling estimation techniques that impose fewer restrictions than those of froot and frankel to test their hypotheses they find that the bias in the forward discount is attributable to both the failure of rational expectations and the existence of time varying risk premia copyright 1994 by university of chicago press

news and the 1920 s experience with floating exchange rates in this paper the news approach to modelling the exchange rate is implemented for the inter war experience with floating exchange rates the results are shown to be broadly supportive of similar tests conducted for the 1970 s experience with floating

money supply announcements interest rates and foreign exchange abstract this paper presents a test of the joint hypothesis that money supply announcements affect the real interest rate and that changes in the real interest rate affect the exchange rate in the short run the test results are consistent with the joint hypothesis for example it is found that announcement of an unexpected jump in the money supply is accompanied by an increase in interest rates and an appreciation of the dollar if the rise in interest rates was entirely due to higher inflationary expectations the dollar should not appreciate

marginal reductions in vehicle emissions under a dual blend ethanol mandate evidence from a natural experiment among the many reasons policy makers across the world have sought to supplement fuel supplies with ethanol blended fuels are the cited environmental benefits that come with replacing a fossil fuel with a cleaner burning alternative dual blend ethanol mandates in which multiple ethanol blends are simultaneously available are one way policy markers can move forward with more aggressive mandates more quickly the recent ethanol mandate in the state of new south wales australia offers a unique natural experiment to quantify the potential environmental benefits and costs of a dual blend ethanol policy this paper estimates the impact on carbon dioxide co2 emissions from road activity that are attributable to the implementation of the new south wales ethanol requirements we find that there was a decrease in emissions due to the policy but that the decrease is relatively minor given the size of the market and that it comes at a high cost the cost was over 1200 per ton of carbon to reduce gasoline emissions by just 1 2

exchange rate market efficiency and new information abstract this paper uses a multi currency approach to analyze the relationship between forward exchange rates future spot rates and new information the empirical results tend to support the hypothesis that the exchange rate can be expressed as a function of factors known in advance and news

once in a generation yen volatility in 1998 fundamentals intervention and order flow abstract the dramatic yen dollar volatility of 1998 has been popularly ascribed to order flow driven by changing tastes for risk and hedge fund herding on unwinding yen carry trade positions rather than fundamentals high frequency evidence of shifting fundamentals is provided by a comprehensive list of macroeconomic announcements news is found to have significant effects on volatility but order flow may play a more important role since portfolio shifts are revealed to the market through trading the results are consistent with order flow playing a significant role in the revelation of private information and associated exchange rate shifts

macroeconomic news order flows and exchange rates under rational expectations and efficient markets the news contained in public information announcements is directly impounded into prices with there being no role for trades in this process of information assimilation this paper directly tests this assertion using transaction level exchange rate data and a sample of scheduled macroeconomic announcements the main result of the paper is that even information that is publicly and simultaneously released to all market participants is largely impounded into prices via the key micro level price determinant order flow we quantify the role that order flow plays and find that between a half and two thirds of price relevant information is incorporated into prices via the trading process

exchange rate returns news and risk premia abstract using a new survey data set of matched exchange rate and interest rate expectations for eight currencies relative to the german mark we examine empirically the relationship between exchange rate returns news and risk premia news on interest differentials enters significantly in equations for the difference between the spot rate and the lagged forward rate for the british pound japanese yen spanish peseta and the us dollar an unexpected rise in the interest rate differential tends to strengthen the domestic exchange rate for each of these currencies we also find significant effects of our ex ante measure of the risk premium in addition we investigate the effect of lagged interest rate differentials as a proxy for the risk premium and find that they do not capture time varying risk premia as is widely suggested in the literature but probably reflect a peso problem learning about a policy change a market inefficiency or a combination of these factors

the speed of gasoline price response in markets with and without edgeworth cycles retail gasoline prices are known to respond fairly slowly to wholesale price changes this does not appear to be true for markets with edgeworth price cycles recently many retail gasoline markets in the midwestern u s and in other countries have been shown to exhibit price cycles in which competition generates rapid cyclical retail price movements we show that cost changes in cycling markets are passed on 2 to 3 times faster than in markets without cycles we argue that the constant price movement inherent within the edgeworth cycle eliminates price frictions and allows firms to pass on cost fluctuations more easily

the policy anticipation hypothesis and the expected inflation hypothesis some new evidence using index linked bonds abstract using price index linked and conventional bonds issued by the uk government estimates of expected inflation and the expected real interest rate are derived these estimates are employed to investigate the relationship between components of the nominal interest rate and surprise monetary change the empirical results support the expected inflation hypothesis rather than the policy anticipation hypothesis

market perceptions of federal reserve policy and the weekly monetary announcements abstract in october 1979 the federal reserve altered its operating procedures emphasizing control of the growth rate of the money stock was the fed able to gain credibility in the market the paper investigates this question by examining the reactions of spot and expected future exchange rates foreign interest rates and long run domestic forward interest rates to the weekly federal reserve announcements of m l both before and after october 1979 the empirical evidence points out that the fed did gain credibility but was unable to establish full credibility the market reactions are consistent with the hypothesis that market participants attached a positive probability to the event that the fed may at some point in the future abandon its money stock targets

the ricardian equivalence proposition evidence from foreign exchange markets abstract the major argument against running large government budget deficits is that they raise interest rates and crowd out real investment conclusive evidence of a relationship between large budget deficits and high interest rates has not been found two competing explanations are tested by examining the impact of government udget announcements on foreign exchange rates the ricardian equivalence proposition that deficits have no crowding out effects is compared to the conventional open economy hhypothesis that capital mobility transfers these effects to foreign exchange rates the results supports the open economy hypothesis over the ricardian equivalence proposition jel f41

private investment in higher education comparing alternative funding schemes this paper uses an overlapping generations framework to analyse the implications of different financing regimes in the education sector for human capital formation and economic welfare agents privately invest in education after they have received a noisy information signal about their abilities the incentives of individuals to invest in education are determined by the financing regime under which the economy operates we analyse and compare three financing regimes under each regime the payback obligation of an educational loan is contingent to some extent on an individual s future income

substitution between biofuels and fossil fuels is there a green paradox we show that i subsidies for renewable energy policies with the intention of encouraging substitution away from fossil fuels may accentuate climate change damages by hastening fossil fuel extraction and that ii the opposite result holds under some specified conditions we focus on the case of subsidies for renewable resources produced under increasing marginal costs and assume that both the renewable resources and the fossil fuels are currently in use such subsidies have a direct effect and an indirect effect working in opposite directions the direct effect is the reduction in demand for fossil fuels at any given price the indirect effect is the reduction in the current equilibrium price for fossil fuels which tends to increase the amount of fossil fuels demanded whether the sum of the two effects will actually result in an earlier or later date of exhaustion of the stock of fossil fuels depends on the curvature of the demand curve for energy and of the supply curve for the renewable substitute

a meta analysis of the price elasticity of gasoline demand a sur approach abstract automobile gasoline demand can be expressed as a multiplicative function of fuel efficiency mileage per car and car ownership this implies a linear relationship between the price elasticity of total fuel demand and the price elasticities of fuel efficiency mileage per car and car ownership in this meta analytical study we aim to investigate and explain the variation in empirical estimates of the price elasticity of gasoline demand a methodological novelty is that we use the linear relationship between the elasticities to develop a meta analytical estimation approach based on a seemingly unrelated regression sur model with cross equation restrictions this approach enables us to combine observations of different elasticities and thus increase our sample size furthermore it allows for a more detailed interpretation of our meta regression results the empirical results of the study demonstrate that the sur approach leads to more precise results i e lower standard errors than a standard meta analytical approach we find that with mean short run and long run price elasticities of 0 34 and 0 84 respectively the demand for gasoline is not very price sensitive both in the short and the long run the impact of a change in the gasoline price on demand is mainly driven by responses in fuel efficiency and mileage per car and to a slightly lesser degree by changes in car ownership furthermore we find that study characteristics relating to the geographic area studied the year of the study the type of data used the time horizon and the functional specification of the demand equation have a significant impact on the estimated value of the price elasticity of gasoline demand

regulated and unregulated substitutes aversion effects of an ethanol mandate i introduction regulation is a tool policymakers can use to steer markets away from private outcomes deemed to be socially suboptimal or inefficient regulations work either by altering market incentives or changing consumers choice sets as they attempt to reshape or restrict private market equilibria they can sometimes lead to unexpected consumer reactions and unanticipated consequences such as higher consumer costs or reduced effectiveness in meeting goals the extent to which a regulation can have adverse and unanticipated consequences depends on the nature and design of the regulation in this article we highlight a case where the design of an unpopular and hurried regulation led to especially adverse consequences the case is that of the recent ethanol mandate in the state of new south wales nsw australia ethanol mandates have become popular with legislators over the past decade and currently 62 countries have some form of one grfa 2014 a typical mandate requires producers to blend a certain percentage or certain volume of ethanol into the overall supply of gasoline the u s mandate for example requires 18 2 billion gallons of renewable fuels primarily ethanol be blended into the gasoline supply in 2014 up from 16 6 billion in 2013 epa 2013 the european union mandate requires 5 75 renewable fuels in gasoline by 2010 and 10 by 2020 eu 2003 2009 ethanol mandates have been controversial however griffin 2013 grafton kompas and van long 2012 rodriguez et al 2009 serra and zilberman 2013 westbrook et al 2014 and others proponents argue they help slow greenhouse gas accumulation promote renewable energy and reduce dependence on foreign oil they also point out benefits to the domestic farming and ethanol production industries which is sometimes a goal in itself critics on the other hand question their environmental value the need for fossil fuel replacement the lower energy yield and potential for food price inflation when crops grown for food are converted to ethanol use carter rausser and smith 2013 1 they also point out that ethanol blends tend to be more expensive for consumers on an energy adjusted basis than unblended gasoline mandates tend to be on net unpopular with consumers 2 an important consideration when transitioning to a new ethanol mandate or a higher ethanol blend under an existing mandate is ensuring compatibility with the vehicle fleet ethanol is an alcohol and in higher concentrations can be corrosive to engine valves seals and gaskets in older vehicles not designed with ethanol s properties in mind an option many jurisdictions have used in implementing ethanol mandates is to limit the ethanol blend to a level tested and widely believed to be compatible with the vast majority of vehicles on the road in the united states and canada for example a 10 blend has been implemented almost universally while a 5 blend has been used universally in many european countries if regulators instead deem that higher blends are desirable another option is to mandate that newly built vehicles be compatible with the new higher blend and then implement the fuel mandate once the vehicle fleet has largely turned over however vehicle turnover can take decades and this approach has not been as popular with regulators a third option that has found some favor is to introduce a higher ethanol blend that a majority of vehicles can use while still making the previous possibly ethanol free blend available as long as there are those who still need it in principle this dual blend approach promises to accommodate more aggressive ethanol mandates and lead to more ethanol in the fuel supply more quickly however we show that this kind of dual blend or selective mandate in its efforts to hurry ethanol blending beyond the capabilities of the vehicle fleet as a whole or beyond the confidence of consumers in its safety can have severe negative consequences

further evidence on exchange rate expectations abstract this paper considers a previously unexploited survey data set of exchange rate expectations which allows us to focus on differences between ems and dollar exchange rates we corroborate the earlier finding in the literature that exchange rate forecasts are not rational and that agents do not use all available information efficiently although extrapolative and adaptive expectations formation mechanisms describe non ems exchange rate expectations to a certain extent ems exchange rates forecasts seem to follow long run fundamentals more closely and would suggest that agents believe that ems exchange rate expectations undershoot their long run equilibrium values jel f31

the effect of relative monetary surprises on spot exchange rates this paper examines the hypothetical relationship between us and canadian monetary surprises and the behaviour of us canadian spot exchange rates past studies have found that positive us monetary surprises were correlated with an appreciating us dollar in foreign exchange markets in this paper it is argued that monetary surprises in the us must be measured relative to foreign monetary innovation rather than in the conventional absolute sense when examining their impact on exchange markets rational investors consider expected returns and risk differentials in the us and local markets jointly in determining whether to be net buyers or sellers of us dollars the monetary actions of both the fed and the central bank operating in the local foreign economy will be considered in the foreign exchange market because of the close synchronization between the weekly money supply announcements in canada and the us it is possible to examine whether the relative or absolute us monetary surprise is more signifi

biofuel economics in a setting of multiple objectives unintended consequences this paper examines biofuels from an economic perspective and evaluates the merits of promoting biofuel production in the context of the policies multiple objectives life cycle implications pecuniary externalities and other unintended consequences the policy goals most often cited are to reduce fossil fuel use and to lower greenhouse gas emissions but the presence of multiple objectives and various indirect effects complicates normative evaluation to address some of these complicating factors we look at a several combinations of policy alternatives that achieve the same set of incremental gains along the two primary targeted policy dimensions making it possible to compare the costs and cost effectiveness of each combination of policies for example when this approach is applied to u s produced biofuels they are found to be 14 31 times as costly as alternatives like raising the gas tax or promoting energy efficiency improvements the analysis also finds the scale of the potential contributions of biofuels to be extremely small in both the u s and eu mandated u s corn ethanol production for 2025 reduces u s petroleum input use by 1 75 and would have negligible net effects on co2 emissions and although eu imports of brazilian ethanol may look better given the high costs of other alternatives this option is equivalent at most to a 1 20 reduction in eu gasoline consumption

do retail gasoline prices respond asymmetrically to cost shocks the influence of edgeworth cycles asymmetric price cycles similar to edgeworth cycles are appearing in increasingly many retail gasoline markets in the united states and worldwide the asymmetry in the cycles can give rise to a finding of asymmetric price responses to cost shocks asymmetric passthrough this article estimates asymmetric passthrough for the market of toronto which exhibits cycles and decomposes it into two components that part explainable by the cycles and that part driven by other unknown sources significant asymmetric passthrough is found with increases passed through more quickly than decreases a significant cause of the finding is the presence of the cycles themselves

trade deficit announcements intervention and the dollar abstract the effect of u s trade deficit announcements on the dollar exchange rate from 1980 1988 is examined the announcement is found to affect the dollar only after mid 1984 central bank intervention does not appear to have had a consistent impact on the dollar on the day of the announcement

floating exchange rates expectations and new information abstract this paper analyzes the relationship between forward exchange rates future spot rates and new information a stochastic model of exchange rate determination is used to formally show how unanticipated changes in the exchange rate determinants or news affect the spot rate the empirical analysis indicates that new information plays an important role in explaining the market forecasting error or difference between the spot rate and the forward rate determined in the previous period

effects of us interest rates and news on the daily interest rates of a highly indebted emerging economy evidence from turkey it has been widely demonstrated that asset prices react sensitively to macroeconomic news releases both in the industrialized countries and emerging markets however there are contradicting results on the effects of changes in interest rates of industrialized countries on asset prices of emerging markets in heavily indebted economies in addition to these factors political news and announcements from international institutions that may increase or decrease concerns about debt sustainability can affect asset prices as well this potential notwithstanding there has been relatively limited empirical work on the effects of such variables the objective of this study is to quantify the impact of all of these factors on interest rates of a highly indebted emerging economy using daily post crisis data of the turkish economy we show that both good and bad political news international monetary fund announcements and european union related news significantly affected secondary market government securities yi

the pound sterling us dollar exchange rate and the new abstract the theory that the exchange rate responds to the news content of the fundamental variables is tested the innovations in the monetary approach variables are proxied by arima residuals and the reduced form equation for the exchange rate is fitted by 2sls

a quick and easy method for estimating switching costs abstract i develop and test a method for a quick and easy calculation of consumer switching costs among brands in a given industry the theory developed and tested here maps observed brands prices and market shares onto the switching costs which deter a consumer of a specific brand from switching to any other competing brand then i demonstrate how users switching costs can be directly calculated in two different industries a the israeli cellular phone market and b the finnish market for bank deposits this calculation method can be used to calculate switching costs in a wide variety of other industries such as airlines health services computers software telecommunications and more

bilateral exchange rates and risk premia abstract the paper develops a theoretical model of the risk premium in a bilateral exchange rate representative agents in both countries are assumed to hold open positions in foreign exchange together with risky assets denominated in their own currencies also past surpluses in the current account of the balance of payments lead to net foreign asset positions which may partially be covered in the forward markets our two period mean variance model for optimizing investors is combined with standard assumption about the behavior of real exchange rates to give a reduced form equation for the discrepancies between spot rates and lagged forward rates the model is tested for the dollar dm dollar sterling and dollar yen exchange rates using monthly data for the period 1976 86 the null hypothesis of no risk premium is rejected for each of the currencies reported

technological incompatibility endogenous switching costs and lock in systems are goods comprising of durables that are sequentially updated with complements with sequential purchases if suppliers produce incompatible brands consumers who upgrade systems with complements of a different brand must replace the durables they own thus the price of these durables is an endogenous switching cost the paper deals with the concern that firms may use incompatibility to create consumer s switching costs to reduce competition in aftermarkets however it shows that with homogenous durables and small costs of reaching compatibility endogenous switching costs increase intertemporal price competition to the extent that producers prefer to have compatible technologies

order flows news and exchange rate volatility abstract this paper examines the roles of order flow reflecting private information and news reflecting public information in explaining exchange rate volatility analyzing four months of a bank s high frequency dollar euro trading three different kinds of order flow are used in addition to seasonal patterns in explaining volatility we find that only larger sized order flows from financial customers and banks indicating informed trading contribute to explaining volatility whereas flows from commercial customers do not the result is robust when we control for news and other measures of market activity this strengthens the view that exchange rate volatility reflects information processing

using financial prices to test exchange rate models a note the purpose of this note is to illustrate how tests of exchange rate models can be conducted using financial prices rather than macroeconomic data all empirical tests of exchange rate models have met with limited success so far a major problem encountered is the poor quality of the macroeconomic data used most of the data suffer from large measurement error or cannot even be measured directly for example these models often require measures of changes in expected real activity or in monetary policy such variables can only be poorly estimated from time series models on industrial production or money supply the innovation in this paper is to use financial prices such as stock prices instead of the traditional macroeconomic data there exists convincing empirical evidence that stock returns forecast changes in economic activity as measured by industrial production real growth in gnp employment rate or corporate profits fama 5 and geske and roll 8 in the domestic context stock prices have been used to test the relation between economic activity and inflation e g fama 5 geske and roll 8 and solnik 12 in the same spirit stock returns are used in this paper as proxies for changes in economic activity to test the relation between exchange rates and economic activity interest rates are determined by monetary policies and changes in interest rates are used in this article as indicators of monetary shocks the approach used is introduced in section i while the empirical results are presented in section ii the data cover the eight major western countries over the recent period of flexible exchange rates july 1973 to december 1983

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 reaction of exchange rates to economic news this paper examines the short run responses of spot exchange rates to several types of economic news survey data are used to divide economic announcements into expected and unexpected components with the latter measuring news the results indicate that exchange rates are systematically related to unexpected money announcements after the october 1979 switch in federal reserve operating procedures but not before this response does not appear to have changed however after the october 1982 federal reserve regime change short run exchange rate movements are not systematically related to news on inflation or real activity

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers
