the dynamic effects of aggregate demand and supply disturbances another look abstract in a recent paper blanchard and quah american economic review 1989 79 655 673 propose a set of restrictions to identify the structural innovations from a reduced form bivariate model of income growth and unemployment given the assumptions made by blanchard and quah on the time series properties of the data this paper demonstrates that their bivariate model is just a special case of stock and watson s journal of the american statistical association 1988 83 1097 1107 common trends representation more importantly this alternative representation allows the econometrician to test the long run restrictions used by blanchard and quah to distinguish between demand and supply innovations

ungarbled earnings and dividends an analysis and extension of the beaver lambert and morse valuation model abstract this paper examines the beaver lambert and morse 1980 valuation model that capitalizes ungarbled earnings the analysis identifies the model s unspecified capitalization factor and it emphasizes that a complete model of ungarbled earnings must focus on the joint stochastic behavior of earnings and dividends it is shown that expected ungarbled earnings scaled for a constant equal expected dividends except for the scale factor no apparent economic reasons suggest that ungarbled earnings are any different from dividends

maintaining low inflation money interest rates and policy stance abstract this paper presents a systematic empirical relationship between money and subsequent prices and output using us euro area and swiss data since the 1960 1970s monetary developments unlike interest rate stance measures are shown to provide qualitative and quantitative information on subsequent inflation the usefulness of monetary analysis is contrasted to weaknesses in modeling monetary policy and inflation with respectively short term interest rates and real activity measures the analysis sheds light on the recent change in inflation volatility and persistence as well as on the phillips curve flattening and reveals drawbacks in pursuing a low inflation target without considering monetary aggregates

the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

the transactions velocity of money and its efficiency this paper models the unobservable rate of return on money balances r as depending directly on the transactions velocity of money v approximating this relationship linearly the efficient markets hyphothesis emh is shown to imply that first differences of the log of v should either be random or should show negative first order serial correlation at most the empirical evidence presented below is consistent with the emh these results are of interest in three directions first they add support at the macroeconomic level for the emh velocity in the macroeconomy seems to behave as expected based on the fair degree of support for the emh at the micro

is the price level tied to the m2 monetary aggregate in the long run a long run link between money and prices is evident for the united states since the korean war if the m2 measure of money is used and the velocity of m2 v2 is modeled as a mean reverting series this link between m2 and prices is the basis for a dynamic model of inflation that compares favorably in forecasting exercises with phillips curve and more typical monetarist approaches the behavior of v2 is examined from 1870 to the present providing a basis for reconsidering previous findings that v2 follows a random walk copyright 1991 by american economic association

the information content of security prices a second look abstract beaver lambert and morse 1980 employ a regression of percentage change in prices on percentage change in earnings in which data are grouped by the dependent variable reverse regression offers a more intuitive and direct way to assess the information content of security prices the objective of beaver et al while grouping is asymptotically equivalent reverse regression is a more efficient way of examining the incremental explanatory power of lagged values of percentage change in price with respect to accounting earnings

estimation of current quarter gross national product by pooling preliminary labor market data two methods of using labor market data as indicators of contemporaneous gross national product gnp are developed the establishment survey data are used by inverting a partial adjustment equation for hours a second gnp forecast can be extracted from the household survey by using okun s law using preliminary rather than final data adds about 2 to 4 percentage point to the expected value of the root mean squared errors and changes the weights that the pooling procedure assigns to the two forecasts the use of preliminary rather than final data results in a procedure that assigns more importance to the okun s law forecast

institutional change and the velocity of money a century of evidence we study common features in the income velocity of money income and interest rates for canada the u s the u k sweden and norway using annual data from 1870 the recently developed and refined techniques of testing for cointegration are employed the evidence suggests there is a unique long run relationship in velocity but not in income and interest rates moreover we find that only a model which includes institutional change proxies is properly specified we argue that the evidence is best interpreted in the context of common historical developments in the respective countries financial systems

is inflation always and everywhere a monetary phenomenon using a sample of about 160 countries over the last 30 years we test for the quantity theory relationship between money and inflation when analysing the full sample of countries we find a strong positive relation between long run inflation and the money growth rate the relation is not proportional however the strong link between inflation and money growth is almost wholly due to the presence of high or hyper inflation countries in the sample the relationship between inflation and money growth for low inflation countries on average less than 10 per annum over the last 30 years is weak

the long and short of money short run dynamics within a structural model empirical examinations into aggregate money demand functions generally incorporate a monetary aggregate as the dependent variable while this custom may be inefficient it does not create any new difficulties for estimating the demand function s long run parameters as money supply would equal money demand the short run estimates however are not as fortunate as the monetary aggregate is a measure of supply and not demand one needs to tease out the short run responses associated with money demand changes with those which are associated with monetary supply shocks the present article therefore proposes a more complete representation of monetary sector behaviour and in doing so finds significant support for the so called buffer stock money demand models

money and prices evidence from the g7 countries this paper examines the exogeneity of money and prices within a money demand vector error correction model the exogeneity of the variables is central to several buffer stock models however the paper makes two modifications to the traditional approach the first is to explicitly acknowledge the importance of the supply of money function by including the function alongside its demand counterpart the second is to estimate the behaviour of the nominal sector and real sector simultaneously overall the results from the g7 countries suggest that the concerns raised by buffer stock models are relevant

financial technology shocks and the case of the missing m2 m2 growth was unusually weak in the early 1990s when its velocity soared although m2 growth subsequently recovered its velocity plateaued at a high level giving rise to a case of missing money these swings in m2 growth have accompanied opposite swings in bond mutual fund inflows m2 growth is better tracked and the missing m2 problem is resolved when money models are modified to account for shifts in bond mutual fund costs this approach avoids the capital gains and portfolio substitution problems posed by adding bond or equity funds to m2 while capturing the substitution effects relevant to money demand

alternative p models of inflation forecasts i introduction inflation forecasts play a key role in monetary and macroeconomics during the past three decades dramatic changes in the inflationary environment have stimulated a wealth of studies on the relative accuracy of alternative models of inflation forecasts in particular mehra 1988 stockton and glassman 1987 and reichenstein and elliott 1987 found varying performance in traditional models including the term structure phillips curve and typical monetarist models across postwar periods against this background hallman porter and small 1991 hps introduced a model called p star p sup as inflation forecasters holy grail the p sup framework is built on the general perception that inflation over the long run is a monetary phenomenon however as christiano 1989 argued p sup entails no practical implication for shorter run horizons that are of primary interest to inflation forecasters he further pointed out that for the period of 1970 89 one to three year ahead forecasts from p sup are not meaningfully more accurate than those from traditional models the usefulness of p sup as an anchor for the price level also suffers from another limitation the assumption that velocity which is the ratio of nominal gdp to a monetary aggregate is stable over the long run hps justified the validity of this hypothesis based on postwar 1955 88 data for the broad monetary aggregate m2 used in their model during the early 1990s however the growth rate of m2 apparently slowed down relative to that of gdp leading to a sharp rise in m2 velocity this consequently caused p sup to persistently underpredict actual inflation duca 1995a has provided a detailed discussion on plausible sources of this instability in velocity the literature has also offered plausible solutions to correct p sup models for the observed structural change ranging from redefining the relevant monetary aggregate to directly accounting for a trend break in velocity while evidence supports that these individual methods improve upon the original p sup formulation there is a lack of research comparing their performance especially in periods other than the early 1990s the first objective of the present study therefore is to fill this void the second objective of this paper is to reevaluate the robustness of earlier findings regarding the relative performance of hps s original p sup model to this end we divide the full out of sample forecast period of 1970 96 into three subsamples our results reveal a pattern of switching forecast performance between money based and output based models across recent periods the fragility of these models highlights the extent of temporal instability in the inflation generating process this paper proceeds as follows the next section describes alternative p sup model specifications and other inflation forecast models section iii discusses the forecast results section iv summarizes and concludes ii model specifications the p sup model the benchmark of the p sup model is the quantity theory of money which relies on the equation of exchange 1 p sub t equivalent to m sub t v sub t y sub t where p is the price level m is a measure of money supply v is the velocity of money y is the level of output real gdp and a time subscript denotes the current value of a variable it follows that if v sub t and y sub t reach their long run equilibrium levels at mathematical expression omitted and mathematical expression omitted respectively then the current equilibrium price level mathematical expression omitted can be determined as 2 mathematical expression omitted according to hps mathematical expression omitted is measured by the historical mean of v sub t and mathematical expression omitted by the level of potential gdp

time varying stock price response to earnings induced by uncertainty about the time series process of earnings in this paper i examine how changes in the level of uncertainty about the time series process of earnings affect the magnitude of the stock price response to earnings announcements the basic premise is that when there is more uncertainty about the time series parameters of earnings a given level of unexpected earnings can have a larger effect on stock price because it is weighted more heavily by investors in determining the value of the firm tests are based on a simple model in which price is a function of expected future earnings which follow a random walk with drift time

interpreting euro area inflation at high and low frequencies abstract several authors have recently interpreted the european central bank s ecb s two pillar framework as separate approaches to forecast and analyse inflation at different time horizons or frequency bands the ecb has publicly supported this understanding of the framework this paper presents further evidence on the behaviour of euro area inflation using band spectrum regressions which allow for a natural definition of the short and long run in terms of specific frequency bands and causality tests in the frequency domain the main finding is that variations in inflation are well explained by low frequency movements of money and real output growth and high frequency fluctuations of the output gap

market implication of predisc10sure information size and exchange effects differential market reactions to earnings announcements can inter alia be ascribed to the extent to which such announcements entail surprise i e unexpected information the greater the predisclosure information the less the surprise element in earnings announcements since there is no direct measure of predisclosure information the literature has utilized two different proxies i firm size the size effect atiase 1980 1985 and ii exchange listing the exchange effect grant 1980 atiase 1980 argues that private predisclosure information production and dissemination are an increasing function of firm size capitalization if so the amount of unexpected information conveyed to the market by actual earnings reports should be inversely related to firm size other things equal empirical evidence in atiase 1985 supports this hypothesis grant 1980 found that for otc firms the average price revaluation associated with annual earnings announcements is significantly higher in the report week relative to both nonannouncement

can we improve the perceived quality of economic forecasts a number of topics are discussed concerning how economic forecasts can be improved in quality or at least in presentation these include the following using 50 uncertainty intervals rather than 95 noting that even though forecasters use many different techniques they are all occasionally incorrect in the same direction that there is a tendency to underestimate changes that some expectations and recently available data are used insufficiently lagged forecasts errors can help compensate for structural breaks series that are more forecastable could be emphasized and that present methods of evaluating forecasts do not capture the useful properties of some methods compared to alternatives

dynamics of inflation in india a p star approach p star models have become increasingly popular in recent years in developed countries however data constraints have limited their applicability to the ldcs in this paper such a model is attempted for india using both annual and quarterly data for the period 1955 1995 it is found that velocity in india is trend stationary and using cointegration techniques it is then possible to develop a model to gauge inflationary pressures in the economy the model is well calibrated to data and in out of sample forecasts it significantly outperforms a seasonal arma benchmark model the velocity gap version of the model is particularly successful

predisclosure information firm capitalization and security price behavior around earnings announcements several studies on the relationship between earnings reports and security price behavior provide evidence suggesting that a significant portion of the information revealed through earnings reports is reflected in security prices prior to the report month e g ball and brown 1968 and brown and kennelly 1972 this has been attributed at least partly to the existence of other more timely sources of information which allow market agents to forecast earnings prior to their release the evidence above reflects an average finding across all firms one question of interest is whether there are significant systematic crosssectional differences in the security price reactions to earnings announcements of firms which are associated with specific firm characteristics that lead to differential amounts of predisclosure information this study focuses on firm size capitalization as one such characteristic a firm

the relevance of p star analysis to uk monetary policy recent articles have attempted to restore the use of a simple measure of the money supply as an indicator of future price levels p star and to reestablish a causal link from money to prices in this paper we argue that the p star approach is flawed it is certainly more complex than traditional monetarist approaches but the fundamental questions of causality are in no way either affected or resolved we argue that the p star relationship does not have a causal link with prices but rather the causality runs from prices to money we also find that there is some causality running from money to real income so that monetary conditions do seem to have some predictive power for future levels of activity copyright 1994 by royal economic society

the size distribution of innovating firms in the uk 1945 1983 a survey of 4 378 significant innovations shows that firms with fewer than 1 000 employees commercialized a much larger share than is indicated by their share of r and d expenditures innovations per employee have been consistently above average in firms with more than 10 000 employees and have become so in firms with fewer than 1 000 intersectoral variation in the size distribution of innovating firms can be explained as a function of r and d based technological opportunities and of technological ease of entry by user firms with principal activities outside the sector copyright 1987 by blackwell publishing ltd

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

savings and investment some international perspectives consistent with neoclassical growth models recent estimates of the close association between domestic saving and investment rates may allow policy makers the opportunity to alter investment through the introduction of polices that alter domestic savings however such an interpretation presumes an endogenous investment response equally likely at least theoretically is that the close association is maintained by movements in domestic savings the present paper explicitly examines the endogeneity of domestic saving and investment rates for a subset of countries including the united states the results suggest that saving adjustments make up only a small portion of investment behavior

purchasing power parity over the modern float an application in higher order cointegration abstract tests of the ppp hypothesis over the modern float have not fared well one possible source of misspecification is analyzed in this paper it is demonstrated that price levels are second difference stationary or integrated of order two p t i 2 the necessary condition for ppp to hold as a long run equilibrium i e that the exchange rate is cointegrated with the relative price level is augmented by a second condition that requires price levels across countries to cointegrate from i 2 to i 1 these conditions are examined using price indices from the united states and germany and the deutschemark dollar exchange rate

should bond funds be added to m2 abstract in the early 1990s m2 growth has been weaker than estimated while bond mutual funds have grown rapidly this study assesses whether adding bond funds to m2 would yield a monetary aggregate that is more explainable using a standard error correction model of money with and without modifications for bond interest rate and thrift resolution effects results indicate that it is important to net out institutional and ira keogh assets from bond funds as is done for m2 and that adding such a bond fund series to m2 results in an aggregate that is somewhat more explainable than m2

the association between accounting earnings and security returns for large and small firms abstract the differential information hypothesis advanced by atiase 1980 states that information production and dissemination by private parties for the purpose of identifying mispriced securities is an increasing function of firm size this study examines two corollaries of that hypothesis first security prices of large firms anticipate accounting earnings earlier than security prices of small firms second for a given level of unexpected earnings the cumulative abnormal returns of small firms exceed those of large firms the results are generally consistent with atiase s hypothesis

accounting information and corporate governance market and analyst reactions to earnings of firms engaged in proxy contests abstract this paper studies market and analyst reactions to earnings i during a proxy contest for board seats and ii after a proxy contest induced management change despite indications of earnings management during the proxy contest market and analyst reactions are more pronounced than in prior periods and earnings surprises explain more of the cross sectional variation in these reactions market and analyst reactions to earnings released after a successful proxy contest are less pronounced than in prior periods and earnings surprises explain less of the variation in these reactions perhaps due to new managements tendency to take an earnings bath

predictability in financial analyst forecast errors learning or irrationality in this paper we propose a rational learning based explanation for the predictability in financial analysts earnings forecast errors documented in prior literature in particular we argue that the serial correlation pattern in analysts quarterly earnings forecast errors is consistent with an environment in which analysts face parameter uncertainty and learn rationally about the parameters over time using simulations and real data we show that the predictability evidence is more consistent with rational learning than with irrationality fixation on a seasonal random walk model or some other dogmatic belief

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

monetary dynamics a market approach the behaviour of the short run responses implied by the identification of a long run money demand relationship is examined these responses have recently been interpreted as representing the policy stance of the monetary authority however as movements in the monetary aggregate reflect both demand and supply adjustments estimating the short run dynamics solely within the money demand relationship may produce biased results in order to address this issue the paper explicitly acknowledges the importance of the supply of money function by including the function alongside the demand for money function while the interaction of the two equations continues to produce the long run quantity theory result the additional detail provides more accurate estimates of the individual short run adjustments within the two equations

money and inflation in the euro area a case for monetary indicators abstract this paper examines inflation indicators for the euro area by studying the relationship between inflation output money and interest rates using data spanning 1980 2001 the central finding is that both the output gap and the real money gap the difference between the real money stock and the long run equilibrium real money stock contain considerable information regarding future inflation in contrast the eurosystem s money growth indicator the difference between nominal money growth and a reference value the prominent first pillar in its monetary strategy contains little information about future inflation and no information beyond that contained in the output and real money gaps the predictive performance of the output gap has improved compared to that in a previous version of this paper most likely because of better estimation methods

regression direction and weak exogeneity abstract the absence of testing for weak exogeneity in money demand has often led to stark conditioning claims regarding the validity of price equations this paper uses the johansen procedure to explore the conditioning properties of money demand systems for nonborrowed reserves m1 and m2 our results show that irrespective of the specification of the cointegrating relation a feedback mechanism enters the equation for money the opposite however is not true for the price equations the results also cast a warning for single equation models of money demand in that weak exogeneity is sensitive to how the system is defined

formation of inflation expectations from the simple to the rational expectations hypothesis using quarterly survey expectational data for seven ec countries this paper tests how producers form their inflation expectations the results indicate that the simple expectational hypotheses do not give an adequate account of the variation in the price expectational data because they fail to allow for the information contained in forecast models of inflation however the producers generally do not incorporate disequilibrium inflation into their inflation expectations

efficient and competitive rationing abstract the contracts that interest us here are called priority service contracts the salient feature of such contracts is that they specify each customer s priority in obtaining service that is they specify the tank order in which a customer is served out of the available supply until all customers are served or supply is exhausted such contracts essentially establish queues for customers in section 1 the author provides some background about priority service section 2 formulates a basic model and offer several illustrations also describes two main examples that motivate the theoretical development section 3 derives some key results that show how the prices of priority service contracts are designed to induce customers to self select efficient service orders in section 4 the author discusses various ways that state enterprises can organize markets that implement priority service efficiently in section 5 we study the operation of competitive markets for priority service section 6 concludes with some summary remarks two themes are emphasized one is that a state enterprise can promote substantial efficiency gains by substituting priority service for absent spot markets the other is that oligopolistic firms may have insufficient incentives to offer efficient product diversity consequently allocative efficiency depends on entry of numerous firms even so dispersal of supplies among many firms can prevent productive efficiency when there are advantages from pooling supplies

are tax effects important in the long run fisher relationship evidence from the municipal bond market are nominal bonds appropriately discounted for taxes empirical estimnates of the response of nominal interest rates to changes in inflation the fisher effect have failed to produce a definitive answer four reasons have been put forward as possible explanations i tobin effects ii fiscal illusion iii peso problems and iv different estimators utilizing data on taxable and tax exempt bond interest rates and several different estimators we find that the fisher effect estimates are always larger for the taxable bond relative to the tax exempt bond suggesting that fiscal illusion and different estimators cannot account for the previous results how economic agents respond to the tax burdens of assets with different tax treatment is an important issue at both the level of the individual micro and the aggregate economy macro one clear source of evidence would appear to be the market for high quality debt trading in both taxable and tax exempt debt occurs on a daily basis the response of the rates of return on taxable and tax exempt debt to changes in expected inflation are described by the fisher relationship the fisher relationship is one of the oldest equilibrium relationships in financial economics fisher s original proposition was that if the real rate of interest is relatively constant over time a fully perceived change in the purchasing power of money as proxied by the inverse of the rate of inflation would be accompanied by a proportional increase in the nominal interest rate darby 1975 points out that when nominal interest income is taxed as are interest payments on u s treasury bills the fisher relationship implies a response from nominal interest rates that is greater than the change in expected inflation in order to maintain the constant ex ante real interest rate summers 1983 suggests that given average marginal tax rates in the united states the appropriate value of the fisher effect is 1 3 to 1 5 for tax exempt bonds the original fisher specification should be a good approximation implying a fisher effect close to unity in a seminal paper fama 1975 presents evidence to support the hypothesis that changes in nominal

the long run link between money growth and inflation is inflation always a monetary phenomenon many economists believe that the link between money growth and inflation in the u s has weakened over the last two decades due in part to the federal reserve s policy experiment in 1979 1982 and innovations in the financial sector of the economy i find that the long run relationship between money growth and inflation is strong in a statistical sense and important economically the key result is that the trend or growth component in cpi inflation is entirely due to the trend component of monetary base growth jel c32 e31 e51

a review of literature and hypotheses on new technology based firms abstract this paper examines the existing literature on new technology based firms in an attempt to understand how such companies contribute to the vitality of an economy and to see which variables are critical in enabling them to do so from recent research efforts we have drawn together a set of hypotheses and organized them around four central questions 1 what do new firms contribute to the economy 2 what factors contribute to the success of such enterprises 3 in what cultural contexts do new businesses succeed and 4 which government policies are effective in stimulating and supporting new companies we found that existing studies suggest 1 that new technology based firms contribute significantly to an economy in terms of exports employment taxes paid research and development and innovations 2 that the founders of these new businesses tend to have a strong entrepreneurial heritage a development rather research oriented background and a high need to achieve and are young and highly educated 3 that sector differences may be a more important influence on company location than are regional policies and 4 that no one government program has proven itself to be more than marginally successful in stimulating industrial innovation

contrasting models of the effect of inflation on growth the paper formulates a nesting model for studying the theoretical literature on inflation and endogenous growth it analyses different classes of endogenous growth models with different usage of physical and human capital with different exchange technologies first the paper shows that a broad array of models can all generate significant negative effects of inflation on growth second it shows that these models can be differentiated primarily by the fact whether there is a tobin type effect of inflation and also whether the inflation growth effect becomes weaker as the inflation rate rises a non linearity or stays essentially constant over the range of inflation rates the paper compares these features of the models to empirical evidence as a way to summarize the efficacy of the models

monetary analysis and monetary policy in the euro area 1999 2006 abstract this paper assesses the practical experience of monetary analysis at the ecb from the introduction of the euro in 1999 through 2006 the paper exploits a unique and rich real time data set containing both the vintages of data and the economic models that have been employed in the ecb s monetary analysis during the first eight years of monetary union it embodies both a description of how monetary analysis was conducted over this period and a quantitative evaluation of the indicators of risks to price stability that derived from this analysis a close investigation of this material is used to evaluate the role monetary analysis has played in the evolution of monetary policy in the euro area

money and growth revisited abstract conventional wisdom is that if public policy can affect the growth rate of the economy the welfare implications of alternative policies will be large in this paper a stochastic dynamic general equilibrium model with endogenous growth and money is examined in this setting inflation lowers growth through its effect on the return to work however the welfare costs of higher inflation are modest the endogenous labor supply is important in producing this result

eurosystem monetary targeting lessons from u s data abstract using a small empirical model of inflation output and money estimated on u s data we compare the relative performance of monetary targeting and inflation targeting the results show monetary targeting to be quite inefficient yielding both higher inflation and output variability this is true even with a nonstochastic money demand formulation our results are also robust to using a p model of inflation therefore in these popular frameworks there is no support for the prominent role given to money growth in the eurosystem s monetary policy strategy

on the evolution of competitive balance the impact of an increasing global search the coase theorem maintains that where free market precepts exist the allocation of property rights does not impact the distribution of resources an application to major league baseball suggests that institutions such as free agency and the reverse order amateur draft would not impact player distributions and therefore would not impact competitive balance the present study finds that the distribution of wins is generally consistent with the precepts of the coase theorem and therefore suggests a course for those who wish to alter the level of competitive balance major league baseball should increase its focus on expanding the size of its labor pool jel o15 l83 c22

money and velocity during financial crises from the great depression to the great recession abstract this study models the demand for a broad monetary aggregate m2 from the great depression through the great recession key to the model is the interaction between a measure of time variation in economic agents perceived financial risk and an index of the cost of portfolio adjustment the finding of a useful money demand relationship suggests that skepticism regarding the indicator role of a broad liquid money aggregate as a policy guide may be exaggerated further our model provides some guidance for policymakers who face the challenge of unwinding large balance sheets as risk premia return to normal and velocity adjusts

the information content of money in forecasting euro area inflation this article contributes to the debate on the role of money in monetary policy by analysing the information content of money in forecasting euro area inflation we compare the predictive performance within and among various classes of structural and empirical models in a consistent framework using bayesian and other estimation techniques we find that money contains relevant information for inflation in some model classes money based new keynesian dynamic stochastic general equilibrium dsge models and vector autoregressions vars incorporating money perform better than their cashless counterparts but there are also indications that the contribution of money has its limits the marginal contribution of money to forecasting accuracy is often small money adds little to dynamic factor models and it worsens forecasting accuracy of partial equilibrium models finally nonmonetary models dominate monetary models in an all out horserace

forecasting in a large macroeconomic system this paper examines the efficiency gains yielded from estimating multiple equation cointegrated systems as compared to their single equation counterparts in particular this paper is concerned with the ability of utilizing the cointegrating information to improve forecasting performance recently an inability to improve forecasts of real income once money demand error correction terms were introduced has been used to argue that the m2 relationship had broken down during the early 1990s however the results suggest that once the underlying responses of variables are more closely investigated the behaviour of m2 has remained stable

cephalon inc taking risk management theory seriously cephalon inc a biotech firm bought call options on its own stock to meet its conditional cash flow needs we analyze this decision by using the cash flow hedging concepts of froot et al 1993 journal of finance 5 1629 1658 we identify the managerial analyses necessary to apply this theory and discuss managerial considerations absent from the theory we find that managers consider deadweight costs of risk management which theory tends to ignore theory provides little guidance in how to measure these and other deadweight costs finally uncertainty about the availability of external financing and accounting considerations are critical considerations by managers

adding bond funds to m2 in the p star model of inflation abstract during the early 1990s m2 growth has been unusually weak and the p star model has underpredicted inflation at the same time bond funds have grown rapidly we find that the p star model performs well recently when m2 is adjusted for bond funds

do expected shifts in inflation affect estimates of the long run fisher relation recent empirical studies suggest that nominal interest rates and expected inflation do not move together one for one in the long run a finding at odds with many theoretical models this article shows that these results can be deceptive when the process followed by inflation shifts infrequently we characterize the shifts in inflation by a markov switching model based upon this model s forecasts we reexamine the long run relationship between nominal interest rates and inflation interestingly we are unable to reject the hypothesis that in the long run nominal interest rates reflect expected inflation one for one

exogeneity within the m2 demand function evidence from a large macroeconomic system a large body of literature investigates whether a stable and predictable long run association between money and its arguments exists one point of variation between models is whether to include an interest rate measure directly within the long run relationship several recent studies indicate that empirical findings are sensitive to the choice therefore the present article reexamines the empirical significance of the interest rate within a four equation macroeconomic system the results suggest that the interest rate 1 may be excluded from the m2 demand function 2 is strongly exogenous to most of the system s remaining variables and 3 may represent a common trend jel e41 e52 c32 i introduction much of recent macroeconomic literature has been dedicated to investigating whether long run relationships exist between macroeconomic variables 1 such preoccupation is understandable given the myriad models in which these relationships play a dominant role a significant portion of this literature has focused on whether a long run relationship exists between money demand and its arguments 2 of course the close association between the variables is an integral part of theories that suggest that the monetary authority may qualitatively influence the direction of the aggregate economy the estimation of long run money demand models have differed in their methodological approach and in countless other ways one specific way in which they may differ in whether the investigator s incorporates an interest rate measure directly within the long run relationship for example although fischer and nicholetti 1993 and baba et al 1992 incorporate various interest rate measures to identify the long run money demand function hendry and mizon 1998 and hendry and ericsson 1991 estimate the long run money demand function without an interest rate measure although the theoretical importance of the interest rate within the money demand function predates pigou s 1917 classic treatment and has been discussed at length elsewhere the importance empirically has recently been high lighted by sims 1980 in examining whether money granger causes output sims s results suggest that the tests are sensitive to whether a short term interest rate measure is included campbell and perron 1991 further argue that sims s findings are an outgrowth of whether the trivariate model of money prices and output are cointegrated that is i 0 or whether reduction to stationarity requires the introduction of a fourth variable the interest rate reduction to stationarity is important because estimating granger causality with nonstationary residuals may yield biased estimates due to nonstandard residual distributions the present article reexamines the significance of the interest rate within the long run money demand function specifically i examine two aspects of interest rate money behavior the initial examination is to test whether the interest rate measure three month treasury bill rate can be directly excluded from the long run m2 demand function following the methodology advanced by hendry and mizon 1993 johansen and juselius 1992 1994 and ericsson et al 1990 the test involves estimating the long run relationship with the interest rate measure and then impose the overidentifying zero restriction the associated log likelihood ratio statistics are distributed chi square n where n represents the number of overidentifying restrictions this approach however only examines whether the interest rate may be removed from the long run money demand vector a second area of interest is concerned with the short run responses of the interest rate more specifically the short run responses provide a test for granger causality within the cointegrated variables following ericsson et al 1998 granger causality is estimated where one or more cointegrated variables reject strong exogeneity

m3 money demand and excess liquidity in the euro area recent empirical studies have found evidence of unstable long run money demand functions if recent data are used if the link between money balances and the macroeconomy is fragile the rationale of monetary aggregates in the ecb strategy has to be doubted in contrast we present a stable long run money demand relationship for m3 for the period 1983 2006 to obtain the result the short run homogeneity restriction between money and prices is relaxed and a break in the income elasticity of money demand after 2001 is taken into account measures of excess liquidity do not show significant inflation pressures

more evidence on the money output relationship i introduction the empirical relationship between money and real output continues to produce conflicting evidence stock and watson 1989 using monthly u s data for the period 1960 85 report that while actual money growth m1 does not granger cause the growth of industrial production its detrended component does krol and ohanian 1990 internationalize stock and watson s study and find that both actual and detrended ml growth granger cause output growth in the u k but that neither series affects output growth in japan canada and germany friedman and kuttner 1992a 1992b 1993 question the role of money in explaining output behavior they report 1993 that even though the stock watson specification is used simply updating the sample through 1990 yields the result that detrended m1 growth no longer explains output growth friedman and kuttner also argue that the commercial paper rate or the spread between the three month treasury bill and the commercial paper rate provides a better gauge for output s reaction to monetary policy changes replacing the treasury bill rate used by stock and watson with the commercial paper rate or the spread friedman and kuttner find that m1 growth has no marginal explanatory power over output a feature of recent investigations of the money output link is the general use of a var specification based on the presumption that the series are difference stationary e g feldstein and stock 1994 several recent studies however have questioned this presumption due to the low power of unit root tests dejong et al 1992 dejong 1992 dejong and whiteman 1991a 1991b and rudebusch 1993 these studies suggest that it is difficult to distinguish between difference stationary as the null and trend stationary as the alternative hypothesis given the uncertainty about the existence of a unit root in economic time series we re examine the money output relation by specifically considering the affect of assuming that the series are trend stationary or difference stationary such an investigation is important to determine if permanent temporary changes in money and other series create permanent temporary shifts in real output for example if real output and money contain a unit root i e they are best represented by the difference stationary model permanent money shocks may produce permanent shifts in output put another way permanent money shocks may have a long run impact because they affect the stochastic trend component of output and thus change the output level for all future horizons on the other hand if output and other series are represented by a trend stationary model fluctuations around a trend level of these series are stationary mean reverting under this model a transitory money shock may only have a short run impact on output as it quickly returns to its trend level to analyze the sensitivity of results to different stationarity assumptions used we estimate two var systems one system uses the log levels of the variables along with a deterministic time trend the other uses the log difference of the series and excludes the trend term the first system represents the trend stationary specification and the second one represents the difference stationary specification there is some evidence that the money output link may be sensitive to the presence of a deterministic trend term e g eichenbaum and singleton 1986 stock and watson 1989 even so our study provides a direct comparison based on identical data sets of the effects that the two different stationarity specifications have on the money output results while testing the robustness of the money output connection is our main focus we also provide some different perspectives on the debate one is to use both long and short term data sets most studies limit the analysis to quarterly data from the post 1960 era we study the link between money interest rates and output using annual data over the extended period 1915 1993

locational and organizational determinants of r d employment in high technology firms felsenstein d and shachar a 1988 locational and organizational determinants of r d employment in high technology firms reg studies 22 477 486 a causal model is presented that predicts the relationship between the organizational structure and location of the high technology firm on the one hand and its r d employment intensity on the other the organizational structure of the firm is treated in two ways the intra organizational internal structure of the firm is analysed and found to be significantly and negatively related to the level of r d employment in the firm this is contrary to the hypothesisied direction of relationship variables representing the inter organizational environment of the firm however are found to be associated with r d employment intensity in the manner expected the results further show that r d employment intensity is positively associated with metropolitan location unmediated by the effects of firm size this suggests that small high technology firms due to their liab

lessons on monetary policy from the 1980s t he half decade running from mid 1982 to mid 1987 was a pretty good era for u s monetary policy as these things go a sharp easing of policy beginning some time around midyear 1982 helped set in motion a recovery from the most severe business downturn the united states had experienced since the 1930s a downturn that tight monetary policy earlier on had deliberately brought about in order to slow the alarming acceleration of prices the recovery that ensued developed into a sustained expansion that continued without interruption through the end of 1987 thereby setting a new record for the longest recorded business expansion in u s peacetime experience a fiscal policy based on unprecedentedly large and continually growing structural budget deficits was a major factor underlying this record length expansion but at least monetary policy did not stand in the way just as importantly the severe 1981 82 recession served its intended purpose of substantially restoring price stability and even after five years of expansion inflation remained modest by recent historical standards at least as judged by these outcomes for the standard objectives of macroeconomic policy u s monetary policy was a distinct success during these years economists hoping to say something useful about monetary policy have had a tougher time the quantitative relationships connecting income and price movements to the growth of familiar monetary aggregates including especially the m1 measure of the money stock that had been the chief focus of monetary policy during 1979 82 utterly fell apart during this period moreover the collapse of these long standing

liquidity and real activity in a simple open economy model abstract this paper analyzes the ability of an open economy version of lucas s 1990 liquidity model to account for properties of international data the focus is on the model s ability to account for exchange rate dynamics and measured effects of monetary policy shocks on exchange rates interest rates and real activities across countries the model generates a prediction that a positive domestic monetary innovation is associated with nominal and real currency depreciations however the model s predictions with respect to nominal and real exchange rate volatilities are low

savings and investment in australia it has become popular to advocate tax reduction on the basis of promoting savings investment and ultimately economic growth the linkage between the variables is argued by various neoclassical growth models and is further suggested by recent studies which highlight the close association between domestic saving and investment rates the close association may allow for polices which alter domestic saving levels in order to alter domestic investment levels this interpretation however presumes an endogenous investment response equally likely theoretically is that the close association is maintained by movements in national savings the present paper explicitly examines the endogeneity of the australian saving and investment rates the results highlight the exogeneity of investment the results further suggest an endogenous response on the part of australia s saving rate the results may limit the potential benefits of these tax changes

inflation and monetary dynamics in the us a quantity theory approach in this article we investigate the long run link between inflation and money growth in the united states since 1960 a measure of the long run inflation trend is constructed which bears the interpreation of monetary inflation rate and is directly related to the excess nominal money growth process money growth less output growth as postulated by the quantity theory consistent with the memory characteristics of the series their fractional integration and cointegration properties are taken into account in empirical modelling the proposed measure is then compared with several existing measures of core inflation aimed at capturing long run inflation dynamics but unrelated to money growth the monetary long run inflation rate performs well in out of sample forecasting exercises especially over a 2 3 year horizon yielding valuable information to monetary policymakers
