settlement tax and non synchronous effects in the basis of u k stock index futures abstract the basis in stock index futures markets is analytically and empirically studied in this paper within a no arbitrage cost of carry framework explanatory power improved when the implications of the u k stock exchange settlement system were introduced into the modelling process and until recently with the maturity of the market evidence indicating the presence of non synchronicities between the cash and futures markets was found strong evidence for tax effects upon the basis was not found to be present in the data analysed statistically significant relationships between basis mispricing and volume and volatility were found

the phillips curve macroeconomic policy and the welfare of canadians a review of the two competing paradigms explaining inflation and unemployment fluctuations singles out the keynesian phillips curve as the clear empirical winner over its classic competitors reestimation of the canadian phillips curve for 1957 90 identifies a sharp structural shift toward a high degree of unemployment hysteresis after 1972 the recent attempt of macropolicy to flatten the aggregate demand curve and limit supply side shock accommodation which aims at lower and more stable inflation is then shown to make unemployment higher and more unstable on average to an extent that is an increasing function of the degree of hysteresis understanding and reducing hysteresis and developing a consensus based incomes policy that has a chance of alleviating the dismal trade off should therefore to top research and policy priorities

one security many markets determining the contributions to price discovery when homogeneous or closely linked securities trade in multiple markets it is often of interest to determine where price discovery the incorporation of new information occurs this article suggests an econometric approach based on an implicit unobservable efficient price common to all markets the information share associated with a particular market is defined as the proportional contribution of that market s innovations to the innovation in the common efficient price applied to quotes for the thirty dow stocks the technique suggests that the preponderance of the price discovery takes place at the new york stock exchange nyse a median 92 7 percent information share although most of the classic paradigms in market microstructure concern a security that trades in a single centralized market such situations are becoming increasingly rare in practice fragmentation the dispersal of trading in a security to multiple sites has emerged as a dominant institutional trend this process is of concern to financial economists and regulators because price information and price discovery the impounding of new information into the security price arguably the most important products of a security market have many attributes of public goods as the process of fragmentation accelerates it may be important to determine where the price information and price discovery are being produced 1 this paper suggests a practical econometric approach to this problem the technique is illustrated with an application to u s equity markets many stocks listed on the new york stock exchange nyse trade concurrently on the regional exchanges and the national association of securities dealers national market system nasd nms since a share of ibm stock is the same security whether purchased on the midwest or pacific exchange this is a particularly clear instance of multiple markets nevertheless the expres

information technology and time based competition in financial markets this paper studies time based competition in imperfect securities markets linking it investment decisions information processing delays and trading strategies at the it investment stage traders trade off the cost of it against their anticipated trading profits at the trading stage each trader devises a trading strategy based on his new information while taking into account the impact of both his own trades and those of other traders in the market our results illustrate how traders react to market imperfections due to trading costs and information processing delays and how superior traders convert a timeliness advantage into higher trading profits they also shed light on the relationship between the price adjustment process and traders information processing delays timeliness imposes an interesting structure on trader competition traders with longer information processing delays trade less frequently submit smaller orders and enjoy lower profits per trade our analysis of traders it investment decisions demonstrates how factors such as it costs number of traders and the frequency and nature of new information affect the level of it investments we further illustrate how improved it infrastructure translates into competitive advantage

expected inflation and interest rates in a multi asset model a note this paper analyzes the effect of expected inflation on nominal interest rates in a theoretical model with money and two different bond types the inclusion of three assets instead of the usual two causes the effect of expected inflation on the interest rates to deviate from unity depending on the sizes of the wealth and interest rate effects on the various asset demands the effect of expected inflation could even be negative several special cases are also considered and the implications for the interpretation of empirical results are discussed the profession has shown a continuing strong interest in the effect of expected inflation on interest rates both from a theoretical and an empirical perspective fisher s 6 original hypothesis was that there should be a one forone effect so that expected inflation has no effect on the ex ante real interest rate numerous researchers have failed to find that strong an empirical effect on nominal rates however and some have expressed puzzlement over this empirical result the empirical literature includes 1 2 3 5 6 10 13 14 and numerous others theoretical models generally consider a short run situation in which the real rate of return on financial assets is free to deviate from the marginal product of capital the simplest possible such macro model with is lm and vertical aggregate supply curve equations generates the fisher result that dr dir the effect of expected inflation r on the nominal interest rate r equals unity but there are several possible modifications to this model which can drive the value of dr dir either up or down first the mundell 12 effect states that the presence of a real balance effect

stock volatility and the levels of the basis and open interest in futures contracts this article tests a theoretical model of the basis and open interest of stock index futures the model is based on the differences between stock and futures in terms of investors ability to customize stock portfolios and liquidity empirical evidence confirms the model s prediction that increased volatility decreases the basis and increases open interest copyright 1995 by american finance association

reexamining intraday simultaneity in stock index futures markets abstract this note examines three empirical examples involving intraday dynamic relationships associated with stock index futures markets researchers often employ a vector autoregressive var model to analyze such high frequency transactions data while such a model can provide useful information regarding the nature of causal priority inherent in the data it is not the proper model to investigate the structural relationships of interest because it omits the contemporaneous interaction on the other hand a var model specification which is altered to incorporate simultaneity may enable the data to reveal the structural relationships of interest

the effects of inflation on real interest rates one of the most obvious facts of recent monetary history is that high inflation is associated with high nominal interest rates this association has been interpreted by many as supporting a superneutrality hypothesis that an increase in inflation will not affect real interest rates in the long run however the bulk of the evidence contradicts superneutrality beginning with irving fisher 1896 1930 most empirical investigations have found that fully anticipated inflation has less than a unit effect on nominal interest rates and thus reduces real interest rates even in the longest of runs this has been shown under the assumption that expectations are formed rationally douglas pearce 1979 that they take the form of an arbitrary distributed lag on past inflation rates fisher 1930 william gibson 1970 or that they are accurately represented by the livingstone expectations data pearce kajal lahiri 1976 lawrence summers 1983 attempted to measure the long run effect without an explicit theory of expectations regressing long swings in various nominal interest rates against long swings in inflation over various subintervals from 1860 to 1979 he found coefficients consistently less than unity for the post world war ii era as a whole the coefficients were in the range of 0 5 to 0 75 with standard deviations of 0 08 to 0 33 a few studies have found coefficients close to unity william yohe and denis karnosky 1969 martin feldstein and otto eckstein 1970 gibson 1972 lucas but as several authors have observed thomas sargent 1976 robert shiller 1980 john wood 1981 summers these findings are limited to a particular period of u s history approximately 1953 71 furthermore even a unitcoefficient would contradict superneutrality of the after tax real interest rate which would require a coefficient substantially greater than unity even taking into account the other inflation distortions in the tax system summers calculated that the coefficient ought to lie in the range of 1 3 to 1 5 far higher than observed these empirical findings pose a challenge to traditional monetary theory much of which implies that superneutrality should hold at least approximately for example the model of miguel sidrauski 1967 implies that the real interest rate should equal the marginal product of capital which in the long run should equal the representative household s marginal rate of time preference if this rate of time preference is a constant then in particular it will be independent of the rate of inflation if it is positively related to the household s wealth or utility then inflation can reduce the marginal product of capital somewhat through what are commonly called mundell tobin effects that is higher inflation can reduce the demand for real balances which reduces real wealth which lowers the rate of time preference and leads to further capital accumulation 2 but this real balance effect on saving is commonly recognized to be too small to make department of economics social science centre university of western ontario london canada n6a 5c2 we are grateful to charles adams norman cameron john chilton jacob frenkel david laidler ben mccallum baldev raj brad reid jack weldon john whalley ron winrck and two anonymous referees for helpful discussions and comments on earlier drafts all errors are attributable to transaction costs robert lucas 1980 finds empirical support for the hypothesis which he calls one of the central implications of the quantity theory of money it has also been adopted by a wide range of more eclectic economists as evidenced by its endorsement in two of the most popular macroeconomics textbooks rudiger dornbusch and stanley fischer 1981 pp 454 58 robert j gordon 1978 pp 289 91 2these implications of variable time preference can be drawn almost immediately from the work of hirofumi uzawa 1968 a graphical analysis is presented by david laidler 1969b who focuses on the logically equivalent question of the effects of paying interest on money

retrospectives the cyclical behavior of labor productivity and the emergence of the labor hoarding concept the concept of labor hoarding at least in its modern form was first fully articulated in the early 1960s by arthur okun 1963 by the end of the 20th century the concept of labor hoarding had become an accepted part of economists explanations of the workings of labor markets and of the relationship between labor productivity and economic fluctuations the emergence of this concept involved the conjunction of three key elements the fact that measured labor productivity was found to be procyclical rising during expansions and falling during contractions a perceived contradiction with the theory of the neoclassical firm in a competitive economy and a possible explanation based on optimizing behavior on the part of firms each of these three elements fact contradiction and explanation has a history of its own dating back to at least the opening decades of the twentieth century telling the story of the emergence of the modern labor hoarding concept requires recounting these three histories histories that involve the work of economists motivated by diverse purposes and often not mainly if at all concerned with the questions that the labor hoarding concept was ultimately used to address as a final twist to the story the long standing positive relationship between labor productivity and output in the us economy began to disappear in the late 1980s and during the great recession labor productivity rose while the economy contracted

interaction between stock markets an analysis of the common trading hours at the london and new york stock exchange abstract this paper examines the spill overs in both returns and volatility between the london and new york stock markets during overlapping trading hours using high frequency data for the ftse and s p stock index futures we estimate the seasonal patterns in volatility using a flexible fourier form specification the estimated seasonals are used to adjust the returns before conducting the lead lag analysis the results indicate that both markets influence each other although the impact of the usa on the uk is clearly stronger

the linkages persistence asymmetry in the volatility the price discovery and efficiency and the effect of the us subprime mortgage financial crisis on the spot and the futures market s returns the case of india abstractthis article examines the effects of persistence asymmetry and the us subprime mortgage crisis on the volatility of the returns and also the price discovery efficiency and the linkages and causality between the spot and futures volatility by using various classes of the arch and garch models and through the granger s causality we have used two indices one for spot and the other for futures for the daily data from 12 june 2000 to 30 september 2013 from nifty stock indices we have then tested for arch effects and subsequently employed various models of the arch and garch conditional volatility the garch 1 1 model is found to be significant and it implies that the returns are not autocorrelated and have short memory it supports the hypothesis of the efficiency of the markets the negative news has more significant effect on volatility corroborating the leverage impact in finance on market volatility we have also tested the volatility spillover effects the two methods we employed

understanding real business cycles he 1 960s were a time of great optimism for macroeconomists many economists viewed the business cycle as dead the keynesian model was the reigning paradigm and it provided all the necessary instructions for manipulating the levers of monetary and fiscal policy to control aggregate demand inflation occurred if aggregate demand was stimulated excessively and unemployment arose if demand was insufficient the only dilemma faced by policymakers was determining the most desirable location along this inflation unemployment tradeoff or phillips curve the remaining intellectual challenge was to establish coherent microeconomic foundations for the aggregate behavioral relations posited by the keynesian framework but this was broadly regarded as a detail that should not deter policymakers in their efforts to stabilize the economy the return of the business cycle in the 1970s after almost a decade of economic expansion and the accompanying high rates of inflation came as a rude awakening for many economists it became increasingly apparent that the basic keynesian framework was not the appropriate vehicle for understanding what happens during a business cycle nor did it seem capable of providing the empirically correct answers to questions involving changes in the economic environment or changes in monetary or fiscal policy the view that keynesian economics was an empirical success even if it lacked sound theoretical foundations could no longer be taken seriously the essential flaw in the keynesian interpretation of macroeconomic phenomenon was the absence of a consistent foundation based on the choice theoretic framework of microeconomics two important papers one by milton friedman 1968 and the other by robert lucas 1976 forcefully demonstrated examples of

family labor supply and aggregate fluctuations abstract this paper considers an economy which is populated by a continuum of identical families consisting of two members the two members have different productivities and the family faces a fixed utility cost if both members supply labor simultaneously although both family members have the same preferences they display very different elasticities of labor supply a real business cycle model is calibrated and it is seen that this cross sectional heterogeneity results in interesting forms of aggregation bias

real business cycle models of the great depression a critical survey recent years have witnessed a revival of interest in the great depression of the 1930s among the differing new interpretations the real business cycle rbc approach is particularly significant it represents an outstanding methodological innovation in trying to cast the great depression within an equilibrium framework this paper critically reviews the rbc interpretation of the great depression clarifying its theoretical and methodological foundations and paving the way for future assessments of its validity

price discovery and volatility spillovers in index futures markets some evidence from mexico abstract this paper investigates the hypotheses that the recently established mexican stock index futures market effectively serves the price discovery function and that the introduction of futures trading has provoked volatility in the underlying spot market we test both hypotheses simultaneously with daily data from mexico in the context of a modified egarch model that also incorporates possible cointegration between the futures and spot markets the evidence supports both hypotheses suggesting that the futures market in mexico is a useful price discovery vehicle although futures trading has also been a source of instability for the spot market several managerial implications are derived and discussed

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

international price discovery in finnish stock index futures and cash markets abstract this paper investigates empirically how the information of the world s stock markets is reflected in the thin finnish stock index futures and cash markets the world wide returns seem to have a significant leading ability for predicting finnish stock index futures returns however this kind of causal relation is not observed between the world wide and stock market returns the finnish stock index futures returns then show significant granger causality with finnish stock market returns the stock market being the lagging one the relationship is improved by allowing the association between markets to be different for positive and negative returns the findings of this study suggest short selling restrictions and other market frictions to be a significant factor leading to a delay in the pricing process in the stock market

the dynamics of stock index and stock index futures returns in rational efficiently functioning markets the returns on stock index and stock index futures contracts should be perfectly contemporaneously correlated this study investigates the time series properties of 5 minute intraday returns of stock index and stock index futures contracts and finds that sp however the effect is not completely unidirectional with lagged stock index returns having a mild positive predictive impact on futures returns

price flexibility and output stability an old keynesian view in this symposium i shall play the role in which i was cast the unreconstructed old keynesian considering the alternatives i do not mind being billed as a keynesian an old keynesian at that but old keynesians come in several varieties and i speak for no one but myself nor do i defend the literal text of the general theory several generations of economists have criticized amended and elaborated that seminal work i shall argue for the validity of the major propositions that distinguish keynesian macroeconomics from old or new classical macroeconomics

information transmission and market interactions across the atlantic an empirical study on the natural gas market abstract this paper studies the international information transmission and market interactions in the u s and u k natural gas markets three well documented approaches are used to measure the relative importance on the process of price discovery under a quadvariate system after adjusting the effects of nonsynchronous trading prices robust results indicate our system that includes spot and futures prices within the two countries are driven by one common factor information disseminates efficiently among the four markets concerned the u s futures market dominates as the center for price discovery the u k futures market comes as the second the spot markets in the u s and u k are less efficient than their corresponding futures market where the u k spot market contributes the least and almost zero to the price discovery process asymmetric volatility spillovers are found in three of the four markets volatility in the u s futures market increases with positive returns which illustrates the inverse leverage effect in most of the commodity market volatilities in the spot markets are negatively related to returns which is analogous to the traditional leverage effect prevailing in most of the equity stock markets

the fischer black hypothesis some time series evidence we estimate an arch m model to analyze the relationship between the conditional standard deviation of real gross national product gnp and its growth rate for the period 1871 1993 we find that variability significantly increases output growth rates in addition impulse response functions show that the effect of variability on growth rates is dynamic these results provide evidence in favor of black s 1987 business cycle hypothesis

searching for the productivity slowdown some surprising findings from west german manufacturing we test the hypothesis of a negative long term trend and or a structural break in total factor productivity tfp after the first oil price shock for west german manufacturing industries within an econometric model based on a flexible cost function with capital as a quasi fixed factor after adjusting tfp growth for scale economies and varying capacity utilization this hypothesis is not supported by our empirical findings for the great majority of industries studied whereas the hypothesis that the log level of tfp follows a random walk with drift is not rejected by various statistical tests authors

general equilibrium stock index futures prices theory and empirical evidence we develop a closed form general equilibrium model of stock index futures prices in a continuous time economy with stochastic interest rates and market volatility we show that futures prices implied by the model have very different properties from those of the cost of carry model using nyse stock index futures data we examine the restrictions imposed on futures prices by both the equilibrium and cost of carry models consistent with the equilibrium model we find that stock index futures prices are related to market volatility and that their interest rate sensitivity is a nonlinear function of contract maturity

the temporal price relationship between s p 500 futures and the s p 500 index this paper empirically examines the intraday price relationship between s p 500 futures and the s p 500 index using minute to minute data three stage least squares regression is used to estimate lead and lag relationships with estimates for expiration days of the s p 500 futures compared with estimates for days prior to expiration the results suggest that futures price movements consistently lead index movements by twenty to forty five minutes while movements in the index rarely affect futures beyond one minute

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

a further analysis of the lead lag relationship between the cash market and stock index futures market the intraday lead lag relation between returns of the major market cash index and returns of the major market index futures and s p 500 futures is investigated empirical results show strong evidence that the futures leads the cash index and weak evidence that the cash index leads the futures the asymmetric lead lag relation holds between the futures and all component stocks including those that trade in almost every five minute interval evidence indicates that when more stocks move together market wide information the futures leads the cash index to a greater degree this suggests that the futures market is the main source of market wide information article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

index arbitrage and dynamics between reit index futures and spot prices abstractthis article contributes to the real estate literature by investigating the pricing relationship between reit index futures and spot based on the cost of carry model we first show that there exist three arbitrage regimes in australia s reit spot futures price dynamics further analysis indicates that the two thresholds which separate the regimes are largely consistent with the level dictated by transaction costs we then estimate a threshold vector error correction model tvecm the results show that mean reversion of the mispricing error only takes place in the two outer regimes furthermore we find evidence that reit spot market is more informationally efficient than the futures market given its short history it will take time for reit index futures market to mature finally we find that we can enhance hedging performance by accommodating the feature of threshold cointegration displayed by the data as the futures spot relationship differs across regimes we can develop a hedging strate

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

on the informational flow between financial markets abstract this paper investigates the informational flow from the world s stock markets to the small finnish stock and stock index futures markets our results indicate that the returns of the world s stock markets are reflected more strongly in the finnish stock index futures market than in the finnish stock market this is apparently due to trading mechanisms short selling restrictions and thin trading in the helsinki stock exchange thus our evidence suggests that results concerning the informational flow between the world s financial markets may be significantly underestimated if purely stock market returns are used in the tests

futures trading information and spot price volatility evidence for the ftse 100 stock index futures contract using garch abstract this paper examines the impact of trading in the ftse 100 stock index futures on the volatility of the underlying spot market to examine the relationship between information and volatility as subject neglected in previous studies the garch family of techniques is used the results suggest that futures trading has led to increased volatility but that the nature of volatility has not changed post futures the finding of price changes being integrated pre futures but being stationary post futures implies that the introduction of futures has improved the speed and quality of information flowing to the spot market

measuring cash futures temporal effects in the uk using partial adjustment factors abstract the nature and extent of intertemporal adjustments across stock index futures and cash markets in the uk are investigated in terms of partial adjustment factors this approach affords the means of establishing both differential price movements in these markets and additionally providing a readily interpretable measure of the degree of such relative price movements analytic expressions are developed for jointly measuring the partial adjustment factors in cash and futures markets using a partial adjustment with noise model the measures are adjusted for non synchronous trading and asymptotic sampling variances derived adjustment factors are estimated using daily data over the period 1984 1992 with differencing intervals ranging from one to thirty days price adjustments were found to be fuller in futures markets particularly over shorter differencing intervals corrections for non synchronous effects in the cash market increased the magnitude of price adjustment as did the exclusion of data from the 1987 crash period

firm specific information and the correlation between individual stocks and bonds abstract this paper examines the correlation between the returns on individual stocks and the yield changes of individual bonds issued by the same firm and finds that they are negatively and contemporaneously correlated this suggests that individual stocks and bonds are driven by firm specific information that is predominantly related to the mean rather than the variance of the firm s underlying assets furthermore i find that lagged stock returns have explanatory power for current bond yield changes while current stock returns are unrelated to lagged bond yield changes this shows that stocks lead bonds in reflecting firm specific information

index arbitrage with heterogeneous investors a smooth transition error correction analysis abstract the traditional index arbitrage model assumes a constant threshold mispricing between the futures and cash prices for all investors allowing for heterogeneity in investors transaction costs objectives and capital constraints we model the intraday mispricing of djia futures as a smooth transition autoregressive star process with the speed of adjustment toward equilibrium varying directly with the mispricing we show that the observed mean reversion in mispricing changes is induced by heterogeneous arbitrageurs instead of a statistical illusion infrequent trading of index portfolio stocks we further use a star error correction model to describe the nonlinear dynamics between the djia futures and index this model describes not only which market is more informationally efficient than the other but also the legging process the nonsimultaneous establishing of cash and futures positions

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

index arbitrage and nonlinear dynamics between the s p 500 futures and cash we use a cost of carry model with nonzero transaction costs to motivate estimation of a nonlinear dynamic relationship between the s p 500 futures and cash indexes discontinuous arbitrage suggests that a threshold error correction mechanism may characterize many aspects of the relationship between the futures and cash indexes we use minute by minute data on the s p 500 futures and cash indexes the results indicate that nonlinear dynamics are important and related to arbitrage and suggest that arbitrage is associated with more rapid convergence of the basis to the cost of carry than would be indicated by a linear model article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

fisher phillips friedman and the measured impact of inflation on interest a reply the purpose of this paper is to demonstrate that empirical findings which persistently appear to contradict the fisher hypothesis that the nominal rate of interest should rise by the full amount of an increase in anticipated inflation are due basically to a failure to control for changes in the real rate of interest that are associated with changes in anticipated inflation we are guided in our search for proper specification of a fisher equation by a simple general equilibrium model which is employed to derive the impact of a change in anticipated inflation upon nominal interest given the requirement that commodity money and labor markets remain in equilibrium in effect we depart from the empirical tradition which has grown up around testing of the fisher hypothesis that takes the real interest rate to be independent of anticipated inflation and argues that for anticipated inflation properly measured the data ought to support the fisher hypothesis 1

can opec cause inflation and recession abstract this paper addresses an issue that has been the subject of debate in the media and in academic circles the issue concerns the effect of higher oil prices initiated by opec on economic activity in oecd countries results of cointegration tests indicate that there is no long run relationship between oil prices and macroeconomic variables in oecd countries however causality testing indicates the existence of unidirectional causality from oil prices to domestic prices and output

hedging performance and basis risk in stock index futures in early 1982 trading began at three different exchanges in futures contracts based on stock indexes stock index futures were an immediate success and quickly led to a proliferation of new futures and options markets tied to various indexes one reason for this success was that index futures greatly extended the range of investment and risk management strategies available to investors by offering them for the first time the possibility of unbundling the market and nonmarket components of risk and return in their portfolios many portfolio management and other hedging applications in investment banking and security trading have been described elsewhere1 ranging from use by a passive fund manager to reduce risk over a long time horizon to use by an underwriter to hedge the market risk exposure in a stock offering for one or two days in considering the potential applications of index futures it is clear that in nearly every case a cross hedge is involved that is the stock position that is being hedged is different from the underlying portfolio for the index contract 2 this means that return and risk for an index futures hedge will depend upon the behavior of the basis i e the difference between the futures price and the cash price hedging a position in stock will necessarily expose it to some measure of basis risk risk that the change in the futures price over time will not track exactly the value of the cash position basis risk can arise from a number of different sources and is a more significant problem for stock index contracts than for other financial futures like treasury bills and bonds 3 the most apparent cause of basis risk is the nonmarket component of return on the cash stock position since the index contract is tied to the behavior of an underlying stock market index nonmarket risk cannot be hedged this is the essential problem of a cross hedge however basis risk can be present even when the hedge involves a position in the index portfolio itself and there is no nonmarket risk for one thing returns to the index portfolio include dividends while the index and the index future only track the capital value of the portfolio any risk associated with dividends on the portfolio will become basis risk in a hedged position still dividends are fairly low and also quite stable so this may not be a terribly important shortcoming

every cloud has a silver lining fast trading microwave connectivity and trading costs modern markets are characterized by speed differentials with some traders being fractions of a second faster than others theoretical models suggest that such differentials may have both positive and negative effects on liquidity and gains from trade we examine these effects by studying a series of exogenous weather episodes that temporarily remove the speed advantages of the fastest traders by disrupting their microwave networks the disruptions are associated with lower adverse selection and lower trading costs in additional analysis we show that the long term removal of speed differentials results in similar effects and also increases gains from trade

intra day tests of the efficiency of the treasury bill futures market in this paper we use intra day prices to examine the efficiency of the treasury bill futures market the use of intra day data allows us to carefully match in time trades in the futures and cash markets by matching trades and allowing delays between observing apparent inefficiencies and the trade we are examining realistic trading strategies we find profitable arbitrage swaps and a preferred strategy for initial purchase these profits do not depend on an assumption of an equilibrium model hence these tests are direct tests of efficiency rather than a joint test of efficiency and equilibrium t his paper examines the efficiency of the treasury bill futures market this subject has been examined before by capozza and cornell 1979 cornell 1981 lang and rasche 1978 rendleman and carabini 1979 vignola and dale 1979 poole 1978 and puglisi 1978 there are a number of reasons why this paper makes an important contribution to the literature the first reason is that by using trade by trade futures prices we can make more realistic assumptions about the pnces at which trades could have taken place this paper uses intra day prices to examine efficiency prior studies at best used closing prices to examine apparent inefficiencies and assumed that transactions took place at these closing prices there are two problems with this procedure first simultaneous transactions cannot actually occur at closing prices there is almost an hour difference between the closing of the chicago futures and new york spot markets thus when the closing spot market price is observed the futures market has been closed for about an hour closing prices could be used to judge apparent discrepancies however it would be necessary to execute trades at the open making decisions based on closing prices and then assuming trades can take place at these prices is an approximation which could significantly affect results in addition using only closing prices ignores any intra day trades which could lead to profits in this study we match in time intra day prices in the spot and futures market these matched prices are used to identify apparently profitable trading rules we then assume trades take place at prices which are observed later in the day this is a test of a trading rule which an investor could actually follow as we discuss later in the paper our results differ from prior studies these differences are primarily due to using intra day prices and carefully matching times so that information used to initiate trades would actually be available to the investor at the time of the trade the second reason is that we examine more complex trading strategies than those which have been employed in other studies the random walk literature provides a useful analogy the original random walk studies simply correlated past and future prices or returns later studies examined filter rules and other more complicated trading rules in this study we employ alternative trading rules of increased complexity to test for the existence of trading profits finally we explicitly examine the consequence of t bills futures contracts being futures rather than forward contracts futures contracts unlike forward contracts involve flows every settlement day the intermediate cash flows on futures contracts can affect the profitability of any strategy the only prior study that even considered this effect is the one by rendleman and carabini 1979 they used the theoretical model of cox ingersoll and ross 1981 to try to estimate whether the difference between forward and futures prices was likely to be large enough to affect the payoff from alternative trading strategies this is a useful first attempt however ultimately the effect of daily settlement or marking to the market has to be examined directly as part of trading strategies to see if it affects the outcome of these strategies there are other problems with prior studies these involve gross estimates of prices and averaging data in a way that can mask inefficiencies since these problems are discussed in some detail in rendleman and carabini there is no reason to review them further here probably no area in finance has received more attention than the efficiency literature the reader may well wonder why even given the approximareceived for publication august 23 1982 revision accepted for publication may 20 1983 new york university new york university and baruch college respectively the authors would like to thank the center for the study of futures markets at columbia business school for financial support

relative informational efficiency of cash futures and options markets the case of an emerging market we study the lead lag relationships among the spot futures and options markets on hong kong s hang seng index hsi the young options market experiences thin trading and the option returns lag the cash index returns the more mature futures market experiences active trading yet its lead over the cash index appears to be less than the counterparts in other countries a possible reason is the dominance of a few major stocks in the index and these stocks have symmetric lead lag relations with the futures furthermore the informativeness of the non lasting futures and options quotations seems to depend on the market maturity 2001 elsevier science b v all rights reserved

investigating the causal relationship between quits and wages an exercise in comparative dynamics this paper examines the causal relationship between wages and quits in u s manufacturing industries logit and regression models then relate causality test results to industrial characteristics once these relationships are identified they can be used to predict the causality classification for each industry based on the characteristics of that industry this technique can help the researcher choose the appropriate theoretical model for analysis one finding is that quits respond to wages in most industries but not in industries with highly skilled workforces

intraday relationships among index arbitrage spot and futures price volatility and spot market volume a transactions data test abstract this paper examines intraday temporal relationships among arbitrage spreads cash and futures price volatility and cash trading volume using transactions data for the major market index futures contracts and the component stocks of the index results indicate that changes in the spread have a significant impact on cash and futures price volatility as well as on cash trading volume the impact of the spread however is attenuated by the short sale restriction in the cash market contrary to popular beliefs a more volatile market leads to subsequent decreases in the spread probably because of increases in the supply of arbitrage services or faster price adjustments

intraday volatility in the stock index and stock index futures markets we examine the intraday relationship between returns and returns volatility in the stock index and stock index futures markets our results indicate a strong intermarket dependence in the volatility of the cash and futures returns price innovations that originate in either the stock or futures markets can predict the future volatility in the other market we show that this relationship persists even during periods in which the dependence in the returns themselves appears to weaken the findings are robust to controlling for potential market frictions such as asynchronous trading in the stock index our results have implications for understanding the pattern of information flows between the two markets article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

real business cycles a new keynesian perspective the debate over the source and propagation of economic fluctuations rages as fiercely today as it did 50 years ago in the aftermath of keynes s the general theory and in the midst of the great depression today as then there are two schools of thought the classical school emphasizes the optimization of private economic actors the adjustment of relative prices to equate supply and demand and the efficiency of unfettered markets the keynesian school believes that understanding economic fluctuations requires not just studying the intricacies of general equilibrium but also appreciating the possibility of market failure on a grand scale

fisher s paradox and the theory of interest irving fisher s theory of interest has proved to be a most durable and influential contribution to economic theory a central element of fisher s contribution is the fisher hypothesis that over the longer term the real rate of interest is approximately constant being determined largely by time preference with movements in the nominal interest rate reflecting movements in the rate of inflation one for one the paradox of the fisher hypothesis is that despite its wide acceptance as the cornerstone of interest rate theory most empirical evidence appears to be inconsistent with the hypothesis at least in its strictest form this empirical anomaly was noted by fisher himself who attributed it to money illusion in the fifty years following the publication of the theory of interest a considerable literature has evolved around this paradox the unifying theme of this literature is a common acceptance of the essence of fisher s hypothesis most of the energy in this literature has been devoted to explaining systematic movements in the real rate of interest and to providing reasons why the relationship between the nominal interest rate and inflation may only be approximate in

the new keynesian synthesis the new keynesians made more rapid progress in understanding the microeconomics of unemployment than in understanding the microeconomics of nominal price rigidity but the past five years have seen important breakthroughs in this second area this paper will describe these breakthroughs discuss our current understanding of nominal rigidity and assess the work that remains to be done

real business cycle models and the forecastable movements in output hours and consumption the authors study the movements in output consumption and hours that are forecastable from a vector autoregression and analyze how they differ from those predicted by standard real business cycle models they show that actual forecastable movements in output have a variance about one hundred times larger than those predicted by the model the authors also find that forecastable changes in the three series are strongly positively correlated with each other on the other hand for parameters whose implications are plausible in other respects the model implies that output consumption and hours should not all be expected to move in the same direction copyright 1996 by american economic association

the relationship between daily u s and japanese equity prices evidence from spot versus futures markets abstract the daily and overnight transmission of equity prices between the u s and japan is examined in this paper this study documents that the use of the opening value of an equity index to represent equity prices at the open is unlikely to be reliable and the calculated opening values of the nikkei 225 and especially the s p500 indexes mostly reflect prior days closing prices unlike prior studies this paper accounts for this problem of non synchronous trading at the open and finds that u s equity prices do not lead japanese equity prices as both u s and japanese opening equity prices reflect overnight price changes in the other market

index futures arbitrage and the behavior of stock index futures prices this article examines intraday transaction datafor s p 500 stock indexfutures prices and the intraday quotes for the underlying index the data indicate that thefutures price changes are uncorrelated and that the variability of these price changes exceeds the variability ofprice changes in the s p 500 index this excess variability of the futures over the index remains even after controlling for the nonsynchronous prices in the index quotes which induces autocorrelation in the index changes we advance and examine empirically two hypotheses regarding the difference between the futures price and its theoretical value that this mispricing increases on average with maturity and that it is path dependent evidence supporting these hypotheses is presented

a note on the predictability of finnish stock market returns evidence from stock index futures markets abstract this paper provides further evidence on the predictability of the finnish stock market returns the results show the significant role of index futures returns as an important vehicle in stock market return and volatility prediction

autonomy switching regimes and super exogeneity abstract in recent years the concept of switching regimes and super exogeneity has played a dominant part in the econometric debate the relevance of this discussion for the theories of economic policy is developed by lucas sargent and others in this article the very close parallel to the debate about autonomy in the 1940s is shown

the information content of end of the day index futures returns international evidence from the osaka nikkei 225 futures contract abstract employing a generalized autoregressive conditional heteroskedastic garch time series model this study investigates the relationship between end of the day eod osaka nikkei index futures returns and overnight spot returns for the period september 1988 through june 1991 a statistically significant positive relationship is found between the unexpected component of eod futures returns and overnight spot returns in addition the unexpected component of eod futures returns is positively related to trading period spot returns over the next two trading days these results suggest that eod futures returns reflect the information of informed traders which is partially revealed through trading the recent elimination of eod osaka nikkei futures trading has removed an important source of information dissemination

futures cross hedging with a stationary basis when managing risk frequently only imperfect hedging instruments are at hand we show how to optimally cross hedge risk when the spread between the hedging instrument and the risk is stationary for linear risk positions we derive explicit formulas for the hedge error and for nonlinear positions we show how to obtain numerically efficient estimates finally we demonstrate that even in cases with no clear cut decision concerning the stationarity of the spread it is better to allow for mean reversion of the spread rather than to neglect it

an empirical investigation among real monetary and financial variables abstract this paper attempts to make an empirical contribution to the literature on the relationships among real monetary and financial variables of the economy using the methodology of granger s causality tests our results indicate that i money supply and sp ii money supply seems to lead the s p 500 index and iii the s p 500 index seems to lead the industrial production index our findings tend to confirm the important role played by money supply in the economy and the popular hypothesis that stock return fluctuations are a leading indicator of future real economic activity however our results also show that the causal relationships among these three economic variables are not as statistically significant as the economic and financial literature suggests

interest rates uncertainty and the livingston data the observed relationship between the standard deviation of forecasts and past forecast errors as found in the livingston survey suggests the interpretation of the standard deviation as a measure of inflation uncertainty the mean and the standard deviation for the inflation rate forecast found in the livingston survey furthermore are used as regressors in a reduced form interest rate equation the results indicate a large negative effect of such uncertainty on interest rates the inclusion of the uncertainty measure and commonly omitted lagged values of all variables in our analysis of data leads to more theoretically plausible estimated effects of money growth and expected inflation on interest rates than do standard estimates

international policy design and the sustainability of policy bargains events of the past decade and the persistence of the worldwide recession have underlined the interdependence of the major economics competitive devaluations first illustrated the dangers of unilateral decisions and politicians have regularly called for concerted policies since the bonn economic summit in 1978 economic theory has shown that coordinated policies can bring gains but the question of whether those gains will be significant and how they will be distributed remains unanswered remarkably few empirical results on how interdependence should affect policy design or even on the signs of spillovers between economies have been produced this paper estimates the costs of uncoordinated policies to the us and eec economies and also the potential gains and risks in cooperation it focuses particularly on the process of determining rational policy bargains and whether in an international context such bargains are likely to be sustainable

taxes and the pricing of stock index futures stock index futures prices are generally below the level predicted by simple arbitrage models this paper suggests that the discrepancy between the actual and predicted prices is caused by taxes capital gains and losses are not taxed until they are realized as constantinides demonstrates in a recent paper this gives stockholders a valuable timing option if the stock price drops the investor can pass part of the loss on to the government by selling the stock on the other hand if the stock price rises the investor can postpone the tax by not realizing the gain since this option is not available to stock index futures traders the futures prices will be lower than standard no tax models predict on 24 february 1982 the kansas city board of trade began trading futures contracts on the value line average stock index during the next two months both the chicago mercantile exchange and the new york futures exchange also initiated trading in stock index futures although these contracts are actively traded their prices have puzzled both practitioners and academics the observed

demand shocks supply shocks and the cyclicality of real wages the behaviour of real wages over the business cycle has received increasiing attention in recent years the cyclicality of real wages constitues an important aspect of recent models of the business cycle however empirical studies undertaken to determine whether real wages are procyclical or countercyclical have reported conflicting findings in thiis paper we use vector autoregressions to analyse the cyclicality of real wages we find that the source of the disturbance plays a decisive role in the cyclical behaviour of real wages in particular we demonstrate that a supply shock generates procyclical real wages whereas a demand shock yields countercyclicality

is the political business cycle for real abstract this paper constructs and examines a macroeconomic model which combines features from both real and political business cycle models we augment a standard real business cycle tax model by allowing for varying levels of government partisanship and competence in order to replicate two important empirical regularities first that on average the economy expands early under democratic presidents and contracts early under republican presidents second that presidents whose parties successfully retain the presidency have stronger than average growth in the second half of their terms the model generates both of these features that conform to u s post world war ii data

the october 1987 s p 500 stock futures basis five minute changes in the s p 500 index and futures contract are examined over a ten day period surrounding the october 1987 stock market crash since nonsynchronous trading problems are severe in these data new index estimators are derived and used the estimators use the complete transaction history of all 500 stocks nonsynchronous trading explains part of the large absolute futures cash basis observed during the crash the remainder may be due to disintegration of the two markets even after adjustment for nonsynchronous trading the index displays more autocorrelation than does the futures and the futures leads the index

monetary deregulation and inverting the inverted fisher effect abstract we find evidence that deregulation allowing interest payments on checkable deposits decreased increased the sensitivity of the real nominal rate of interest to expected inflation our results provide further confirmation of the inverted fisher effect

liquidity and the law of one price the case of the futures cash basis deviations from no arbitrage relations should be related to market liquidity because liquidity facilitates arbitrage at the same time a wide futures cash basis may trigger arbitrage trades and in turn affect liquidity we test these ideas by studying the dynamic relation between stock market liquidity and the index futures basis there is evidence of two way granger causality between the short term absolute basis and liquidity and liquidity granger causes longer term absolute bases shocks to the absolute basis predict future stock market liquidity the evidence suggests that liquidity enhances the efficiency of the futures cash pricing system copyright 2007 by the american finance association

intraday relationships between volatility in s p 500 futures prices and volatility in the s p 500 index abstract this paper examines the intraday relationships between the volatility of s p 500 futures prices and the volatility of the s p 500 index we calculate variance measures for minute to minute price changes on a daily basis and across 30 minute intervals the empirical results indicate that i futures volatility is greater than index volatility ii volatility increased for both futures prices and the index in absolute terms from 1984 through 1986 iii both futures and index volatility increased directly with futures trading volume and iv index volatility was systematically greater during the first 30 minutes of trading each day than at other times granger tests however reveal no systematic pattern of futures volatility leading index volatility or index volatility leading futures volatility

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

the international price transmission in stock index futures markets i introduction numerous studies have investigated market linkages and price transmission mechanisms in major international equity markets employing the analytical framework of the vector autoregression var or its variant the error correction model ecm 1 studies such as von furstenberg and jeon 1989 eun and shim 1989 and koch and koch 1991 focus on the short run dynamic pattern of price transmission others like taylor and tonks 1989 and francis and leachman 1998 are primarily interested in the long run pattern of price transmission more recently an increasing number of studies explore both long and short run patterns of price transmission included in this last set are the works of malliaris and urrutia 1992 arshanapalli and doukas 1993 masih and masih 2001 and bessler and yang 2003 among others this study extends the examination of international price transmission to stock index futures markets the article contributes to the existing literature in three aspects first a relatively new empirical framework is applied to allow for inferences of price transmission at three different time horizons instantaneous the short run and the long run building on recent advances in statistical analysis of causal modeling using directed acyclic graphs dags as in spirtes et al 2000 pearl 1995 2000 and swanson and granger 1997 this study is able to explore the contemporaneous causal pattern underlying the correlations among market innovations the existence of strong contemporaneous correlations among market innovations has been well documented in the united states and international stock markets by agmon 1972 eun and shim 1989 koch and koch 1991 housbrouk 1995 and bessler and yang 2003 it is also well recognized by agmon 1972 849 and eun and shim 1989 246 that contemporaneous correlations among market innovations reflect the phenomenon that new information in one market is transmitted and shared by other markets in contemporaneous time due to immediate response to price changes between markets however more in depth analysis on exactly how instantaneous price transmission among market innovations is conducted in international equity markets has not yet been well addressed in the existing literature although bessler and yang 2003 touch on the issue the necessity of imposing constraints in the spirit of the block recursive structure noted by koch and koch 1991 in the dag analysis of var innovations is proposed and discussed thoroughly in this study second innovation accounting analysis is more thoroughly explored in the study innovation accounting tools i e impulse response analysis and forecast error variance decomposition have been commonly used to summarize the dynamic pattern of price transmission among international financial markets the importance of the factorization of innovations i e var residuals in yielding sound inference has been well acknowledged theoretically by bernanke 1986 sims 1986 and swanson and granger 1997 the application of the dag technique as discussed in swanson and granger 1997 and explained in the next section is further key to innovation accounting analysis in this study the instantaneous price transmission pattern between market innovations as identified by the dag analysis provides a data determined solution to the basic problem of orthogonalization of residuals from the ecm and thus is critical to impulse response analysis or forecast error variance decompositions swanson and granger 1997 argue that compared to the choleski decomposition the dag based structural decomposition is sensible but not subjective because it allows for the properties exhibited by the data although several recent studies such as those by bessler and yang 2003 bessler et al 2003 haigh and bessler forthcoming and yang 2003 have used the dag based structural decomposition in a similar setting the study is the first attempt responding to the suggestion by swanson and granger 1997 364 of investigating the empirical implications of the dag based contemporaneous causal modeling
