do macroforecasters herd we show that typical tests of whether forecasters herd will falsely indicate herding behaviour for a variety of types of behaviour and forecasting environments that give rise to disagreement amongst forecasters we establish that forecasters will appear to herd if di erences between them reject noise as opposed to private information or if they arise from informational rigidities noise can have a behavioural interpretation and if so will depend on the behavioural model under consideration an application of the herding tests to us quarterly survey forecasts of inflation and output growth data 1981 2013 does not support herding behaviour

an evaluation of the forecasts of the federal reserve a pooled approach the federal reserve greenbook forecasts of real gdp inflation and unemployment are analysed for the period 1974 to 1997 we consider whether these forecasts exhibit systematic bias and whether efficient use is made of information that is whether revisions to these forecasts over time are predictable rather than analyse the forecasts separately for each horizon of interest we discuss and implement methods that pool information over horizons we conclude that there is evidence of systematic bias and of forecast smoothing of the inflation forecasts

s p 500 cash stock price volatilities s p 500 stock return volatilities are compared to the volatilities of a matched set of stocks after controlling for cross sectional differences in firm attributes known to affect volatility no significant difference in volatility is observed between 1975 and 1983before the start of trade in index futures and index options since then s p 500 stocks have been relatively more volatile the difference is statistically but not economically significant the relative increase occurs primarily in daily returns and only to a lesser extent in longer interval returns other factors besides the start of derivative trade could be responsible for the small increase in volatility stock price volatility has received much attention in the popular press over the last few years especially since the october 19 1987 stock market crash the rise in volatility has alarmed investors regulators and the public in general some suggest that the start of trade in stock index futures and index options increased speculative activity that in turn destabilized cash markets causing higher volatility large trading activity in the derivative contracts makes the suggestion plausible volume in index futures and index options increased dramatically since their introductions in 1982 and 1983 by 1987 the average daily dollar volume in the s p 500 futures contracts alone exceeded the dollar volume of cash s p 500 trade by a factor of about two while the dollar value of the daily net change in total open interest is about 8 of s p 500 stock dollar volume speculative trade in futures and options frequently is accused of destabilizing underlying cash markets the charge has been made for more than a century in the agricultural precious metal and currency markets recent evidence by french and roll 1986 showing stock variance to be strongly related to trading session hours heightens these concerns unfortunately theoretical analyses of whether speculative trade destabilizes cash markets lead to conflicting conclusions depending on what assumptions are made 1 school of business administration university of southern california and office of economic analysis u s securities and exchange commission i wish to thank mary denny mcsweeny and steve hornstein for their valuable research assistance and the referee and editor for their many suggestions and insights the opinions expressed in this paper do not necessarily reflect those of the u s securities and exchange commission or those of the author s colleagues on its staff an increase in well informed speculative trade has two opposite effects on measured volatility it decreases volatility due to order flow imbalances caused by uninformed traders because informed traders provide liquidity in such events and it increases volatility due to new fundamental information since the information which is assumed to be generated at discrete time intervals is impounded into

a comparative analysis of the rationality of consensus forecasts of u s economic indicators the purpose of this article is to investigate the rationality of two survey forecasts of selective u s macroeconomic performance measures that were widely followed in the financial markets during the 1990 2000 period the research compares the rationality of survey forecast data from money market services inc and thomson financial this article extends prior research that has evaluated the rationality of money market services data for earlier time periods while also evaluating similar consensus forecast data from thomson financial that were widely reported in both barron s and the wall street journal during the 1990s

money supply announcements and foreign exchange futures prices for five countries since the federal reserve began targeting money supply growth in october 1979 the effects of fed money supply announcements on financial markets have been intensively examined studies have considered the impacts on financial assets including yields on short term and long term treasury securities forward interest rates exchange rates stock prices and commodity prices these studies suggest that money supply announcements have had significant effects on all these financial assets the effects however have not been consistent across time assets or countries this study adds to the money supply announcement literature focusing on foreign exchange spot and currency future prices mussa 23 provides a justification for this approach he demonstrates that exchange rates move in accord with the efficient markets theory of asset price determination in addition he finds most exchange rate changes are unexpected thus exchange rate changes generally should be related to news since unexpected changes must be due to new information how exchange rates respond to news depends on how that information alters expectations those expectations however depend on economic agents historical experience and on policymakers anticipated reactions thus the effects may vary across countries and across policymaking regimes we believe this study makes four contributions to the money announcement literature first we develop a model of money announcements where expected announcements may be important even when markets are efficient while we consider money announcements in particular the model suggests a general result even expected announcements may affect financial market variables simply by confirming prior expectations second we extend and update the prior literature by examining whether recent money supply announcements have an impact on exchange rates and whether recent impacts differ from those found through 1985 the results suggest the impact of money announcements may have diminished marginally third we extend the analysis to exchange rate currency futures comparing the reactions of spot and futures rates yields further evidence on the policy anticipation versus the expected inflation effects and fourth most prior studies of unanticipated money growth do not distinguish between positive and negative surprises if positive and negative surprises influence market prices asymmetrically however

asymmetric loss and herding behaviour of exchange rate forecasters evidence from south africa this study examines the asymmetry of the loss function for private forecasters in exchange rate forecasts of the south african rand it tests rationality under the possibility of an asymmetric loss function the results indicate less evidence of asymmetry for a horizon of 1 month but considerable evidence of asymmetry for a horizon of 3 months however the shapes of the distributions formed by estimated asymmetry parameters of sub samples for each forecaster are symmetric regardless of the forecast horizons which implies that these forecasters do not herd or antiherd in fact the results of our empirical herding test show that forecasters neither herd nor antiherd which is in sharp contrast to recent findings on antiherding for foreign exchange rates in emerging market economies our findings provide consistent evidence for a recent suggestion that antiherding might result in the rejection of rationality even under asymmetric loss functions our findings also suggest that central bank transparency m

explanations of the inconsistencies in survey respondents forecasts a comparison of the point forecasts and the probability distributions of inflation and output growth made by individual respondents to the us survey of professional forecasters indicates that the two sets of forecasts are sometimes inconsistent we evaluate a number of possible explanations and find that not all forecasters update their histogram forecasts as new information arrives this is supported by the finding that the point forecasts are more accurate than the histograms in terms of first moment prediction c 2009 elsevier b v all rights reserved

time series model forecasts and structural breaks evidence from spanish pre emu interest rates analysis of the future behaviour of economic variables can be biased if structural breaks are not considered when these structural breaks are present the in sample fit of a model gives us a poor guide to ex ante forecast performance this problem is true for both univariate and multivariate analysis and can be extremely important when co integration relationships are analysed the main goal of this article is to analyse the impact of structural breaks on forecast accuracy evaluation we focus on forecasting several interest rates from the spanish interbank money market in order to carry out the analysis we perform two forecasting exercises a without structural breaks and b when structural breaks are explicitly considered we use new sequential methods in order to estimate change points in an endogenous way this method allows us to detect structural breaks in all four rates in may 1993 however the effects of these breaks are not very strong since we found scarce gains in forecasting accuracy w

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

biased predictors rationality and the evaluation of forecasts abstract optimal rational forecasts are often biased and thus the empirical finding that actual forecasts are biased is not necessarily evidence of irrational behavior using an asymmetric loss function and a regression forecasting problem these points are explicitly demonstrated

analyzing the impact of futures trading on spot price volatility evidence from the spot electricity market in france and germany abstract this paper examines the impact of the introduction of electricity futures on the spot price volatility of the french powernext and german eex electricity markets as well as the degree of their price correlation over the period 2002 2011 our working hypotheses were tested based on a bivariate vecm garch model the results indicate that the introduction of futures contracts in the french electricity market as well as the launch of the joint futures market in these countries in 2009 has decreased spot price volatility however this effect was not as explicit for the german market due to data specificities other interesting results are the german market dominates and leads the long run price relationship the impact of cooling needs on demand is greater than the impact of heating needs there is a substantial systematic pattern of electricity prices and their respective volatilities during weekdays and holidays overall results are supportive of policy making at the european commission regarding electricity market integration

rationality testing under asymmetric loss abstract this paper shows that if agents have an asymmetric loss function standard empirical tests for the rationality of their expectations are in general invalid we further show that under a popular class of asymmetric loss functions the linex family a valid test can be carried out by estimating an appropriate arch in mean model the contrast between the standard test and our arch m test is illustrated using the goldsmith nagan forecasts of us treasury bill yields

intertemporal price speculation and the optimal current account deficit abstract the paper studies the effects of terms of trade fluctuations in an infinite horizon optimizing model of a small open economy while the current account response to a transitory terms of trade shock is in part explicable by intertemporal smoothing an important additional factor is the effect of anticipated future terms of trade shifts on the ral value of the external debt in terms of the home consumption basket when foreign borrowing is indexed to the import good a temporary worsening of the terms of trade creates the expectation of a decline in the real value of external debt this fall in the relevant real interest rate leads households to increase consumption while export prices are low and to decrease consumption sharply once the terms of trade recover if an adverse price shock is of sufficiently brief duration instantaneous utility will rise initially

the term structure of euro rates some evidence in support of the expectations hypothesis abstract this paper studies 1 3 6 and 12 month euro rates for 17 countries using between 10 and 30 years of data term spreads contain information about future short term rates in all 51 regressions that we estimate moreover in 35 cases we are unable to reject the expectations hypothesis using cross sectional regressions we estimate the variance of the term premium and the correlation of the term premium and the expected change in short rates we conclude that despite evidence of a time varying term premium for many countries the expectations hypothesis is broadly compatible with the data

bias in federal reserve inflation forecasts is the federal reserve irrational or just cautious abstract inflation forecasts of the federal reserve seem to have systematically under predicted inflation from the fourth quarter of 1968 until volcker s appointment as chairman and to systematically over predict it afterwards until the second quarter of 1998 furthermore under quadratic loss commercial forecasts seem to have information not contained in those forecasts to investigate the cause of this apparent irrationality this paper recovers the loss function implied by federal reserve s inflation forecasts the results suggest that the cost of having inflation above an implicit time varying target was larger than the cost of having inflation below it for the period since volcker and that the opposite was true for the pre volcker era once these asymmetries are taken into account the federal reserve s inflation forecasts are found to be rational

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

the persistence in volatility of the us term premium 1970 1986 abstract this paper examines the persistence of the volatility of the risk premia for excess holding period returns of the term structure using a garch m model of the conditional variance the finding of a high degree of persistence cannot be sustained once allowance is made for a structural break in the unconditional variance caused by a change in the operation of us monetary policy during 1979 1982

disagreement and biases in inflation expectations empirical work documents substantial disagreement in inflation expectations obtained from survey data furthermore the extent of such disagreement varies systematically over time in a way that reflects the level and variance of current inflation this paper oers a simple explanation for these facts based on asymmetries in the forecasters costs of over and under predicting inflation our model implies biased forecasts with positive serial correlation in forecast errors and a cross sectional dispersion that rises with the level and the variance of the inflation rate it also implies that forecast errors at dierent horizons can be predicted through the spread between the short and long term variance of inflation we find empirically that these patterns are present in inflation forecasts from the survey of professional forecasters a constant bias component not explained by asymmetric loss and rational expectations is required to explain the shift in the sign of the bias observed for a substantial portion of forecasters around 1982

perspectives on international trends and dynamics in population and consumption there are increasing concerns that global environmental limits may soon be met as a result of increasing numbers of people coupled with increasing consumption of resources however the current level and rates of growth in both consumption and population vary systematically among countries grouped according to income levels many high income countries have population growth rates at close to replacement levels but their per capita consumption is consistently several times higher than low income countries low income countries need to grow out of poverty and have high population growth rates using current population structures for india and the usa in an age structured demographic model and simple projections of annual reductions in fertility or consumption per capita over the next 50 years we show that while reductions in both consumption and fertility are necessary to stabilize impacts there are short term gains from consumption reductions in high income countries such as the usa and long term gains from early fertility reductions in growing economies such as india

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

derivative securities and cash market stability this study investigates the effect of introducing interest rate futures and options on the price variances in related financial cash markets standard research approaches to this issue relate cash price stability before the introduction of futures and options trading to cash price stability after trading in the derivative security begins however controlling for the additional factors that may also effect cash markets is difficult the approach employed here to deal with this obstacle is motivated by recent theoretical research relating cash and futures markets but hitherto not operationalized to empirically test for a relationship between the markets varying parameter models of 1 the demand for short term treasury securities 2 the demand for large time deposits and 3 the supply of large time deposits are specified such that changes in the parameters imply changes in the volatility of the cash price these parameters are modelled as functions of the trading volume of interest rate futures and o

the forecaster s dilemma influential forecasts occur when the forecast itself determines whether the forecast is tested new product sales forecasts are often influential because a low forecast may cause a firm not to launch a new product so that actual sales are never observed this paper considers a dilemma we face as influential forecasters our client requests an unbiased forecast but pressures sometimes exist to provide a bias forecast from theoretical and empirical perspectives we discuss the impact of these pressures on the quality of forecasts we find that noninfluential forecasts generally create no pressure for statistically biased forecasts as influence increases the pressures increase when our forecasts eliminate alternatives e g product designs advertising campaigns not all forecasts are tested not validating all forecasts causes two effects survivor s curse and prophet s fear survivor s curse makes statistically unbiased forecasts appear optimistic i e overestimate actual sales because often only optimistic forecasts are tested forecasts appearing statistically unbiased or pessimistic might cause concern perhaps some failures are justified prophet s fear encourages pessimistic forecasts because these forecasts cause hidden opportunity losses while optimistic forecasts cause observable actual losses tested forecasts may appear completely unbiased despite a pessimistic pre launch bias although no perfect solution exists clients may lessen bias with experimentation and by seeking more accurate forecasts forecasters may lessen bias with forecasts conditioned on launching and by seeking more accurate forecasts

disequilibrium dynamics with inventories and anticipatory price setting this paper studies the sequence of short run quantity constrained equilibria of a model with a single storable output labor and money the durability of output gives rise to inventory fluctuations which influence the course of the equilibria attained one special feature of interest is the assumption that prices are not at the level which would equilibrate all markets if there were no stochastic shocks to the economy with prices frozen at this level the nature of the realized shocks determines the type of disequilibrium realized and the unintended component of inventory change the analysis concentrates on two questions what is the statistical nature of the process governing the real wage output employment and inventories and is it possible to test this model against the alternative hypothesis that prices are continually flexible even after the shocks have disturbed the system we find that although these theories are similar in their qualitative structure tests can be developed we also show how the frequencies of different types of quantity constrained equilibria vary with the stochastic specification this may shed some insight on why it is commonly believed that some types of disequilibrium phenomena have not been observed this abstract was borrowed from another version of this item

changing beliefs and systematic rational forecast errors with evidence from foreign exchange this paper addresses a new interpretation to the appearance in the early 1980s of systematic errors in forecasting the dollar exchange rate following a change in the process of a fundamental variable market participants revise their beliefs about the process using bayes rule since the market does not immediately recognize the change forecast errors are on average wrong during a period when the market is rationally learning for conservative parameter values the learning behavior of the dollar exchange rate in the early 1980s appears consistent with about half of the dollar s underprediction implied by the forward market copyright 1989 by american economic association

the impact of supply shocks on exchange rates and interest rates does the marshall lerner condition matter we examine the dynamic response of the exchange rate the terms of trade and interest rates to supply shocks in a rational expectation stochastic environment we establish the proposition that the marshall lerner elasticity condition is sufficient to guarantee that an exogenous increase in real economic growth will appreciate the exchange rate regardless of assumptions concerning market clearing and price flexibility in specialized cases the traditional marshall lerner condition is sufficient to establish propositions concerning exchange rate overshooting the direction and magnitude of financial asset price movements and relative volatilities under flexible versus anticipatory pricing regimes

on forecasting interest rates an efficient markets perspective abstract efficient markets do not preclude economic agents from successfully forecasting movements in short term interest rates for brief forecast intervals however ex ante changes in long term rates are sufficiently close to zero that economic agents are not likely to improve upon the no change prediction of the martingale model economic agents in effect are not likely to succeed in forecasting short term movements in long term interest rates this paper illustrates the closeness of the martingale approximation for two sets of canadian interest rates data emphasizing the importance of the forecast interval the paper then examines three sets of recorded forecasts of canadian interest rates and finds results consistent with the theoretical discussion

federal reserve system implementation of monetary policy analytical foundations of the new approach on october 6 1979 the federal reserve announced a change in its open market operating procedures that moved the focus of short run guides for open market operations away from the federal funds rate and toward reserve aggregates under the old procedures the trading desk maintained close week to week control over the federal funds rate within a range specified by the federal open market committee fomc alteration of the funds rate between fomc meetings was subject to guidelines conditional on behavior of the money supply relative to specified tolerance ranges under the new procedures the trading desk targets on a family of reserve aggregates principally nonborrowed and total reserves the reserve operating guides under the new procedures are derived from targets for growth of the monetary aggregates and are expressed as averages of weekly levels over the short run operating period normally the intermeeting period as a corollary less attention is paid to the federal funds rate and it is permitted to vary over a much wider range during the short run operating period as compared with the old procedures it should be understood that the october shift to a reserve operating guide for openmarket operations did not also encompass a change in either the proximate or ultimate objectives of monetary policy they continued to be respectively the money supply and goals for economic growth employment and prices rather the shift involved a change in the technique of achieving the proximate money supply objectives two reasons can be advanced for the shift first the old technique of operating on the federal funds rate seemed to be a less reliable means in practice of attaining the proximate policy objectives second in view of the worsening inflationary psychology at the time a shift to a different technique of operations would help to dramatize the federal reserve s continuing commitment to slowing money growth to curb inflation and thereby would work to reduce inflationary psychology this paper first summarizes the analytical framework underlying the choice between a reserve aggregate and a federal funds rate operating target as well as some previous research bearing on the issue next the technical aspects of implementing the new procedures are explained and contrasted to the theoretical paradigm underlying previous empirical results finally experience with the new procedures since last october is reviewed and some conclusions are drawn

the expectations hypothesis new hope or illusory support abstract recent studies of the expectations hypothesis of the term structure ehts find evidence in favor of the ehts using post 1980s us data this has been attributed to the relative macro stability of this period and greater market efficiency using a panel of forecasts for 3 month interest rates for ten countries we test separately for ehts and rational expectations assuming rational expectations holds we find support for the ehts is illusory due to an off setting time varying term premia and non rational expectations previous forecast based studies suggest biased expectations tend to reinforce the effect of a time varying term premium this change can be understood in the context of fama s 2006 argument that markets tend to underestimate future spot rates during periods of long run increases and overestimate during declines

rational expectations and macroeconomic forecasts the article presents extensive results from testing for bias and serially correlated errors in a collection of time series of quarterly multiperiod forecasts for six variables including real gnp growth inflation and unemployment the analysis covers responses by 79 frequent participants in economic outlook surveys conducted regularly since 1968 it shows much greater incidence of apparently systematic errors for inflation than for the other variables also the tests are more favorable to composite group forecasts than to most of the individual forecast sets

does urbanization lead to less energy use and lower co2 emissions a cross country analysis despite the relationship between urbanization energy use and co2 emissions has been extensively studied in recent years little attention has been paid to differences in development stages or income levels most previous studies have implicitly assumed that the impact of urbanization is homogenous for all countries this assumption can be questionable as there are many characteristic differences among countries of different levels of affluence this paper investigates empirically the effects of urbanization on energy use and co2 emissions with consideration of the different development stages using the stochastic impacts by regression on population affluence and technology stirpat model and a balanced panel dataset of 99 countries over the period 1975 2005 the findings suggest that the impact of urbanization on energy use and emissions varies across the stages of development surprisingly urbanization decreases energy use in the low income group while it increases energy use in the middle and high income groups the impact of urbanization on emissions is positive for all the income groups but it is more pronounced in the middle income group than in the other income groups these novel findings not only help advance the existing literature but also can be of special interest to policy makers and urban planners

federal reserve policy interest rate volatility and the u s capital raising mechanism the object of this paper is to examine in detail on the basis of the experience of the u s financial markets under the federal reserve system s new monetary policy procedures announced on october 6 1979 one potentially important effect on the nonfinancial economy due to the resulting increase in interest rate volatility in particular the possibility that increased volatility has impaired the market mechanism for raising long term business capital interest rate volatility has been a controversial issue in central bank policymaking for a long time the ultimate objectives that central banks pursue almost always refer to nonfinancial aspects of economic activity and well being like price stability and economic growth in carrying out policies designed to further these objectives however central banks typically operate exclusively in the financial markets their actions therefore affect interest rates directly and visibly whether to use this influence on interest rates to smooth out short run fluctuations or alternatively to implement actions focused solely on other objectives and hence leave interest rates to vary freely with the pulse of market pressures is the central question in the united states the evolution of the federal reserve system s monetary policy procedures during the last decade including in particular the changes an

biases in macroeconomic forecasts irrationality or asymmetric loss empirical studies using survey data on expectations have frequently observed that forecasts are biased and have concluded that agents are not rational we establish that existing rationality tests are not robust to even small deviations from symmetric loss and hence have little ability to tell whether the forecaster is irrational or the loss function is asymmetric we quantify the exact trade off between forecast inefficiency and asymmetric loss leading to identical outcomes of standard rationality tests and explore new and more general methods for testing forecast rationality jointly with flexible families of loss functions that embed quadratic loss as a special case an empirical application to survey data on forecasts of nominal output growth demonstrates the empirical significance of our results and finds that rejections of rationality may largely have been driven by the assumption of symmetric loss

futures trading and volatility in the gnma market futures markets for agricultural commodities have existed for well over 100 years recently there has been a major expansion of futures trading into nontraditional areas particularly interest bearing securities and foreign currenciesthe so called financial futures the introduction of exchange traded futures contracts for treasury bills gnma pass through certificates and other securities has created new hedging arbitrage and speculative opportunities for the investors issuers and dealers who are active in the cash markets for these securities futures trading has also opened these markets to participation by new classes of traders particularly private and smaller institutional investors through the process of arbitrage a financial futures market will be closely linked to the cash market for the underlying securities an important concern of the regulatory authorities is what effect opening a futures market is likely to have on an existing cash market the purpose of this paper is to analyze the impact of futures trading in government national mortgage association gnma passthrough certificates on price volatility in the cash market for these securities there are several major ways in which opening futures trading can increase efficiency and smooth price variations in a cash market most importantly futures provide a mechanism for those who buy and sell the actual security or commodity to hedge themselves against unfavorable price changes through the futures market risk can be spread across a large number of investors and transferred away from those hedging spot positions to professional speculators who are more willing and able to bear it this risk transfer may substantially improve the functioning of the spot market because it reduces the need to incorporate risk premia in cash market transactions to compensate for the risk of price fluctuations second futures market may increase the informational efficiency of a cash market since futures prices are determined in a unified highly visible market by traders who specialize in gathering and evaluating information the futures market is expected to be an efficient market in the sense that prices will reflect the best estimate of true future values given the information currently available if anything an informationally efficient futures market should lead to more efficient pricing in the cash market the importance of both of these effects will depend upon the structure of the existing cash market the more developed and integrated is the cash market the

testing the expectations hypothesis in eurodeposits abstract analyzing data on euro rates for 1978 1998 we find some consistent evidence in favor of the expectations hypothesis eh of the term structure a interest rates offered on deposits in a given currency form a cointegrated system b the restrictions of the eh on the cointegrating relationships are not rejected c forward rates contain significant explanatory power on future interest rates unbiasedness being an acceptable hypothesis as a cointegrating relationship between forward rates and the appropriate future value of the corresponding short term interest rate however we also provide evidence that past rates contain information additional to that in forward rates to predict future short term rates against the rational expectations version of the eh and market efficiency

a macro finance model of the term structure monetary policy and the economy this paper develops and estimates a macro finance model that combines a canonical affine no arbitrage finance specification of the term structure with standard macroeconomic aggregate relationships for output and inflation from this new empirical formulation we obtain several interesting results 1 the latent term structure factors from finance no arbitrage models appear to have important macroeconomic and monetary policy underpinnings 2 there is no evidence of monetary policy inertia or a slow partial adjustment of the policy interest rate by the federal reserve and 3 both forward looking and backward looking elements play important roles in macroeconomic dynamics

how well do economists forecast stock market prices a study of the livingston surveys the desire to forecast stock prices appears to be eternal alfred cowles 1933 was one of the first researchers to evaluate statistically how well professional forecasters predict stock prices in this tradition our paper will explore the statistical properties of the livingston stock market forecasts a number of recent studies including those by josef lakonishok 1980 bryan brown and shlomo maital 1981 and douglas pearce 1984 finds that the livingston stock market forecasts are statistically biased and or do not utilize all available information i e are informationally inefficient in contrast to earlier studies we find using 61 semiannual livingston surveys from june 1955 through june 1985 that stock market forecasts are statistically unbiased and minimum error variance estimators in section i we show that earlier studies are likely to mask the true relationships between stock market forecasts and realized rates of return because of inappropriate computational algorithms in section ii we present our statistical results based upon the corrected data algorithm we provide a brief summary of the paper in the last section 1 computing livingston stock market rate of return forecasts

the strategy of professional forecasting we develop and compare two theories of professional forecasters strategic behavior the first theory reputational cheap talk posits that forecasters endeavor to convince the market that they are well informed the market evaluates their forecasting talent on the basis of the forecasts and the realized state if the market expects forecasters to report their posterior expectations honestly then forecasts are shaded toward the prior mean with correct market expectations equilibrium forecasts are imprecise but not shaded the second theory posits that forecasters compete in a forecasting contest with pre specified rules in a winner take all contest equilibrium forecasts are excessively differentiated

cyclical patterns in the variance of economic activity this article models the conditional mean and variance of real gross national product gnp and its components using asymmetric exponential generalized autoregressive conditional hetero scedasticity a model previously applied only to financial variables the results imply that the variance of real gnp is higher following negative innovations than positive innovations and that this asymmetry arises in the cyclically sensitive sectors further evidence links this asymmetry to the phase of the business cycle the conditional variance appears to be largest around business cycle troughs in addition shocks to the conditional variance of gnp and its components typically persist for long periods the evidence of asymmetry in conditional variance is robust to a variety of alternative specifications

economic forecasts rationality and the processing of new information over time this study analyzes real gnp and inflation forecasts published in the blue chip economic indicators the survey revises annual growth rate estimates every month thus making it possible to analyze the value of new information and its contribution to the estimates predictive power of the actual values if information is used efficiently updated forecasts should provide more accurate predictions the empirical results suggest that the revised forecasts of real gnp growth and inflation incorporate new information in a rational manner in addition the most recent inflation forecasts are found to be unbiased estimates on the actual rate of inflation copyright 1990 by ohio state university press

heterogeneous expectations and tests of efficiency in the yen dollar forward exchange rate market this paper examines the efficiency of the forward yen dollar market using micro survey data conventional tests of unbiasedness do not correspond directly to the zero profit condition instead we use the survey data to calculate potential profits of individual forecasters based on a natural trading rule we find that although the survey data are not the best predictor of future spot rates in terms of typical mean square forecast error criteria the survey data can be used to obtain on average positive profits however these profits are small and highly variable similar results are found when we examine profits generated by a trading rule using regression forecasts the profits are found to be correlated with risk type variables but not other available information

the informational efficiency of weekly money announcements an econometric critique studies of the weekly money announcement have found markets to be informationally efficient we demonstrate that this result apparently is related to one or more sources of bias and measurement error that have been introduced to the estimating equations of previous studies after correcting for these sources of bias and estimating the modified model over the samples employed in earlier studies we still find evidence to reject the hypothesis of informational efficiency an alternative explanation is that auxiliary assumptions imposed for empirical convenience introduce measurement error that affects standard tests of the efficient markets hypothesis

new hope for the expectations hypothesis of the term structure of interest rates survey data on interest rate expectations permit separate testing of the two alternative hypotheses in traditional term structure tests that the expectations hypothesis fails and that expected future interest rates are ex post inefficient forecasts we find that the source of the spread s poor predictions of future interest rates varies with maturity at short maturities the expectations hypothesis fails at long maturities however changes in the yield curve reflect changes in expected future rates one for one an implication of the expectations hypothesis this result confirms earlier findings that long rates underreact to short rates but now it cannot be attributed to term premia if the attractiveness of an economic hypothesis is measured by the number of papers which statistically reject it the expectations theory of the term structure is a knockout most tests beginning with macaulay 1938 find no evidence supporting the expectations hypothesis 1 many cannot even reject statistically the alternative hypothesis that the spread between long and short rates contains no information about future interest rate changes 2 to make matters worse in u s postwar data future long rates tend to rise when short rates are above long rates since the expectations hypothesis would predict that long rates tend to fall the theory often does worse than even the naive model that future interest

forecasting canadian short term interest rates the author investigates the forecasting performance of a number of simple prediction techniques for short term interest rates in particular quarterly forecasts of canadian three month t bill rates from one to forty quarters in the future are generated during 1963 92 using several time series methods and market based yield curve strategies comparison is made with the martingale and for a shorter recent sample with the predictions made by several economic forecasters for the most part utilization of the yield curve proved best though it must be granted that no methodology was able to outperform the martingale for horizons up to a year

market and survey forecasts of the three month treasury bill rate in this article four readily available one quarter ahead forecasts of the three month u s treasury bill rate are compared the forecasts considered are 1 a prediction from the futures market 2 a forecast derived from an implicit forward rate calculation 3 a survey gathered forecast and 4 a no change forecast each forecast is examined for general forecast accuracy and for the extent of bias contained in each forecast over the twelve year period 1977 88 results indicate that the futures rate statistically dominates the other three forecasts while the survey and forward rate projections generally are found to be the least accurate and most biased copyright 1992 by university of chicago press

time variation in term premia international survey based evidence using a large previously unexplored data set of survey based interest rate forecasts that covers a broad range of countries this paper re examines the expectations hypothesis of the term structure of interest rates we find that survey based interest rate forecasts outperform not only a random walk forecast but also outperform forecasts from forward rates when using these superior survey based forecasts in a modified expectations hypothesis test the expectations hypothesis is rejected for fewer countries at lower significance levels and has greater explanatory power than when using a traditional forward rates based test we furthermore document strong time variation in the term premia which is an important reason why the traditional expectations hypothesis test is rejected so frequently this time variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure finally we find that generalizing findings from earlier u s studies to other countries may lead to bias in the true economic relationships in these countries

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

on the restricted cointegration test as a test of the rational expectations hypothesis one of the main consequences of the cointegration revolution on the domain of the direct tests of the rational expectations hypothesis reh was the substitution of the restricted cointegration test rct for the unbiasedness test however the results of a monte carlo study show that a simple t test can be much more powerful than the rct it is argued that the rct is adequate to investigate the asymptotic rationality but that it is not sufficient to assess the muthian rationality of expectations the discussion is empirically illustrated with the test of the reh for the portuguese retail trade inflation expectations

the decline in idiosyncratic values of us treasury securities abstract unique features and market frictions can lead to idiosyncratic pricing for some us treasury securities this study uses a linear programming lp model to measure aggregate idiosyncratic pricing of t notes and t bonds from 1980 to 2016 we document an average idiosyncratic pricing of 0 11 per 100 par as compared to an average bid ask spread of 0 08 further idiosyncratic pricing declined dramatically from the early 1980s to the 2010s empirical evidence suggests that the 1986 tax reform act increasing issue sizes and improving market liquidity contribute to the decline at the individual security level we identify factors contributing to and mitigating idiosyncratic pricing

expectation puzzles time varying risk premia and dynamic models of the term structure abstract linear projections of returns on the slope of the yield curve have contradicted the implications of the traditional expectations theory this paper shows that these findings are not puzzling relative to a large class of richer dynamic term structure models specifically we match all the key empirical findings reported by fama and bliss 1987 american economic review 77 4 680 692 and campbell and shiller 1991 review of economic studies 58 495 514 among others within large subclasses of affine and quadratic gaussian term structure models additionally we show that certain risk premium adjusted projections of changes in yields on the slope of the yield curve recover the coefficients of unity predicted by the models key to this matching are parameterizations of the market prices of risk that let the risk factors affect the market prices of risk directly and not only through factor volatilities the risk premiums have a simple form consistent with fama s findings on the predictability of forward rates and are also shown to be consistent with interest rate feedback rules used by a monetary authority in setting monetary policy

more flexible use of survey data on expectations in macroeconomic models a flexible procedure is proposed whereby both the random and systematic errors in measurement of survey data on inflation expectations can be appropriately handled when these surveys are used in the estimation of macroeconomic models during the period 1952 1980 livingston s two expectations series and the src series systematically underestimated inflation expectations by nearly 25 the asa nber survey however does not exhibit such underestimation thus the use of the livingston or src data as an unbiased measure of the true expectations of inflation would result in overestimation of the fisher effect and the ex ante real interest rate

assessing the prudence of economic forecasts in the eu we estimate the eu commission loss preferences for major economic forecasts of 12 member states based on a recently proposed method by elliott komunjer and timmermann 2005 the paper provides evidence of asymmetries in the underlying forecast loss preference of the commission that tend to vary across member states in some cases our results show that eu forecasts tend to display a rather optimistic picture for main economic variables e g government balance thus allowing a certain degree of leeway in the fiscal adjustment path towards the medium term objective of close to balance or in surplus of the recently revised stability and growth pact over the period of our sample 1970 2004 this apparent asymmetry in the underlying loss preferences tends to deter prudent advice over economic policy lastly we provide an analysis on the trade off between loss and distribution asymmetries for which simulation results show that the testing method is robust in the presence of skewness copyright 2009 john wiley sons ltd

the expectations hypothesis of the term structure tests on us german french and uk euro rates abstract this paper tests the expectations hypothesis of the term structure on us german french and uk euro rates three tests are examined the first is based on forward rates and the other two are based on the interest rates spread first we show that the sign puzzle highlighted by campbell and shiller campbell j y shiller r j 1991 yield spreads and interest rate movements a bird s eye view review of economic studies 58 495 514 for us data does not arise in the cases of french and uk short term rates second we propose tests for the expectations hypothesis based on error correction models with these tests the sign puzzle disappears but the country puzzle remains

on the expectations view of the term structure term premia and survey based expectations in this paper uk disaggregate survey data of expected future interest rates are used to test the expectations model of the term structure of interest rates at the short end of the maturity spectrum in the aggregate the expectations model is rejected and both time varying term premia and expected interest rate changes are demonstrated to be important in explaining the slope of the yield curve within the aggregate data however we demonstrate that there are some differences with respect to the views of the term structure held for example for some individuals the pure expectations model cannot be rejected

macroeconomic sources of time varying risk premia in the term structure of interest rates according to intertemporal capital asset pricing models icapm in finance merton 1983 risk premia are the prices of risk built in assets priced according to their hedging capabilities against the uncertainties related to the relevant state variables in the economy as the uncertainties of the state variables change over time the prices of the risk related to the state variables and consequently the risk premia on assets in general vary over time too following the growing evidence of the failure of the expectations hypothesis and the existence of time varying risk premia in the term structure see shiller 1990 for a survey on the literature these equilibrium asset pricing models have received economists attention as an attractive theoretical framework for modeling risk premia in the term structure of interest rates for example breeden 1986 campbell 1986 1987 several empirical studies attempted to test the validity of these equilibrium asset pricing models of the term structure however due to the failure of the theoretical icapm in finance to identify the important state variables most of the studies employed empirical models that do not require a complete explicit representation of the state variables consequently those studies do not reveal any information about the importance of different macroeconomic forcing variables in the determination of time varying risk premia this paper investigates explicitly the linkage between time varying risk premia in the term structure and macroeconomic state variables in that respect the study is

de stabilizing speculation on futures markets an alternative view point abstract this paper offers a new interpretation for possible destabilizing effects of opening futures markets in our model adapted from stein 1987 speculation on futures markets reduces the likelihood of occurrence of a rational expectations equilibrium although the equilibrium price is less volatile after the futures market is opened which is usually viewed as a stabilizing effect traders may find it more difficult or even impossible to coordinate their expectations in order to implement this equilibrium

the expectations hypothesis term premia and the canadian term structure of interest rates in this paper monthly data are used over the period 1960 7 to 1995 12 to examine the determinants of term premia implicit in the canadian t bill term structure of interest rates in sharp contrast to u s evidence the conditional variances of canadian macroeconomic variables are found to be insignificant predictors of term premia in the canadian t bill term structure the conditional variances of u s macroeconomic variables however are found to be important determinants of canadian term premia jel classification e43 g1 l hypothese des anticipations les primes de temps et la structure temporelle des taux d interet canadiens ce memoire utilise des donnees mensuelles de juillet 1960 a decembre 1995 pour examiner les determinants des primes de temps implicites dans la structure des taux d interet pour les bons du tresor canadiens contrairement a ce que l on trouve aux etats unis il semble que les variances conditionnelles des variables macroeconomiques canadiennes ne sont pas des predicteurs utiles de ces primes cependant il appert que les variances conditonnelles des variables macroeconomiques des etats unis sont des determinants importants de ces primes

the impact of financial futures on the cash market for treasury bills this paper is concerned with the effect of futures trading in treasury bills on the volatility of yields in the cash market it is found that futures trading led to a decrease in volatility initially but the effect disappeared when futures volume became large and possibly resulted in increased volatility in the secondary cash market the results also indicated that the deliverable bill appears to sell at a small premium relative to the adjacent maturities prior to the delivery date

the rationality of usda forecasts under multivariate asymmetric loss a large number of previous studies suggest that many usda forecasts are biased and or inefficient these findings however may be the result of the assumed loss function of usda forecasters we test the rationality of the usda net cash income forecasts and the wasde production and price forecasts between 1988 and 2018 using a flexible multivariate loss function that allows for asymmetric loss and non separable forecast errors our results provide robust evidence that usda forecasters are rational expected loss minimizers yet demonstrate a tendency to place a greater weight on under or overprediction as a result this study provides an alternate interpretation of previous findings of forecast irrationality

an evaluation of survey exchange rate forecasts abstract a non parametric test of direction is employed to evaluate the survey forecasts provided by the money market services empirical results suggest that the forecasts are useful for predicting the direction of exchange rate changes the results are consistent with a weaker form of rationality than unbiasedness

oil price forecasting under asymmetric loss based on the approach developed by elliott et al 2005 we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil accounting for the asymmetry of the loss function does not necessarily make forecasts look rational

multiperiod forecasts of interest rates the accuracy of forecasts of interest rates over different forecast horizons and time periods is examined the results indicate a deterioration in absolute forecast accuracy measured by the mean absolute error and the root mean squared error but no decrease in relative accuracy measured by the theil coefficient with an increase in the forecast span the results also indicate a decline in accuracy in periods of volatile interest rates support is found for the hypothesis that the ratio of the variability of predicted changes to that of actual changes falls with an increase in the forecast horizon

the treasury yield curve as a cointegrated system this paper examines the temporal relationship between interest rates on treasury securities ranging in maturity from three months to 30 years we find strong empirical support that the seven treasury rates selected are cointegrated a conclusion that is insensitive to the normalization chosen in particular the hypothesis of noncointegration is rejeeted decisively regardless of the rate selected as the dependent variable in the cointegrating equation to determine whether this information can be used to improve forecasts of treasury rates the seven rates are forecasted with a corresponding erroreorrection model that is shown to outperform an augmented var model that ignores the cointegration of the rates the results are consistent with the belief that arbitrage limits the extent to which rates on different maturities of a given security diverge in addition the results confirm the appropriateness of imposing a common stochastic process for interest rates in equilibrium models of the term structure

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting
