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

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

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

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

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

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

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

the importance of engaging residential energy customers hearts and minds abstract in an attempt to reduce the contribution of residential greenhouse gas emissions the eu has implemented a variety of policy measures the focus has been to promote domestic energy efficiency and ultimately a reduction in residential energy demand in this study we estimate residential energy demand using underlying energy demand trend uedt and asymmetric price responses for 14 european oecd countries between 1978 and 2008 our results support the conclusion that policies to reduce residential energy consumption and the consequent emissions need to account for behavioural lifestyle and cultural factors in order to be effective

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

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

what do revolving door laws do abstracton the basis of evidence from state public utility commissions we find that revolving door laws laws that restrict the post government employment opportunities of public sector workers including public utility regulators do not do much at least with respect to electricity prices in this paper we take advantage of a quasi experiment afforded by the fact that revolving door laws were introduced in different states at different times to investigate their effects on electricity prices our findings suggest that while revolving door laws temporarily dampen industrial electricity prices they have no effect on commercial or residential prices there is also some evidence that these regulations affect the characteristics of state public utility commissioners commissioners from states with revolving door regulations serve shorter terms and are less likely to be subsequently employed in the private sector compared with their counterparts from states without revolving door laws

insider trading in supervised industries abstractwe investigate the impact of government agency oversight such as by the federal reserve on insider trading at the firm level regulatory supervision potentially limits trading based on material nonpublic information as it provides another layer of corporate governance to mitigate outflows of private information yet regulators themselves may serve as a source of information leakage thereby facilitating insider trading activity we find first that in comparison to nonsupervised firms supervised firms exhibit substantially greater trading based on inside information prior to earnings announcements second in the first few days after firms provide private information to regulators or when regulators possess private information inaccessible to corporate insiders these firms exhibit greater symptoms of insider trading finally within a given supervised industry insider trading symptoms appear more pronounced when regulators exhibit greater leniency or operate in states with more political c

redistribution by insurance market regulation analyzing a ban on gender based retirement annuities we illustrate how equilibrium screening models can be used to evaluate the economic consequences of insurance market regulation we calibrate and solve a model of the united kingdom s compulsory annuity market and examine the impact of gender based pricing restrictions we find that the endogenous adjustment of annuity contract menus in response to such restrictions can undo up to half of the redistribution from men to women that would occur with exogenous social security like annuity contracts our findings indicate the importance of endogenous contract responses and illustrate the feasibility of employing theoretical insurance market equilibrium models for quantitative policy analysis

estimating energy and oil demand functions a study of thirteen developing countries abstract in this paper we attempt to identify some of the factors that have determined the level and pattern of energy demand in developing countries during the 1970s and early 1980s aggregate oil and energy demanding functions are constructed for a selection of oil importing countries and oil exporting countries the results show a strong link between income and aggregate energy demand conversely the price elasticity of energy demand is low both in the short run and the long run oil demand behaviour is more complex oil products can be rationed or domestic energy production can affect oil demand nonetheless the income elasticity remains close to one in most countries and is well above one for some

an augmented p star model of indian inflation abstractan augmented p star model is estimated and tested to identify the drivers of inflation in india the model includes monetary and non monetary factors demand pull and cost push factors and

modelling residential electricity demand in the gcc countries abstract this paper aims at understanding the drivers of residential electricity demand in the gulf cooperation council countries by applying the structural time series model in addition to the economic variables of gdp and real electricity prices the model accounts for population weather and a stochastic underlying energy demand trend as a proxy for efficiency and human behaviour the resulting income and price elasticities are informative for policy makers given the paucity of previous estimates for a region with particular political structures and economies subject to large shocks in particular the estimates allow for a sound assessment of the impact of energy related policies suggesting that if policy makers in the region wish to curtail future residential electricity consumption they would need to improve the efficiency of appliances and increase energy using awareness of consumers possibly by education and marketing campaigns moreover even if prices were raised the impact on curbing residential electricity growth in the region is likely to be very small given the low estimated price elasticities unless that is prices were raised so high that expenditure on electricity becomes such a large proportion of income that the price elasticities increase in absolute terms

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

econometric modelling of international carbon tax regimes an econometric model of fossil fuel demand has been estimated for eight oecd countries relating coal oil and gas demands to gdp and prices in addition a model of endogenous technical progress has been estimated aiming to include both price induced innovation in energy and structural change in the economy as long term determinants of energy consumption a number of possible international carbon energy tax agreements are simulated showing the impacts on carbon dioxide emissions and comparing the two models in the long run the magnitude of taxes required to stabilize or reduce emissions would be large and there are important differences between countries in price responses which must be taken into account in international modelling and policy formulation

energy consumption and economic activity in industrialized economies a note abstract in industrialized countries the income elasticity of primary energy demand is not far off unity furthermore it can be argued that there is little use in distinguishing between short and long term income elasticities a long term income elasticity does not have a direct impact on energy demand and hence it is of doubtful use in energy demand projections via an aggregate oecd model it was estimated that the short term impact of prices on primary energy demand is about 0 15 while the long term impact is 0 43 but increasing over time

understanding the spectrum of residential energy saving behaviours french evidence using disaggregated data analysing household energy saving behaviours is crucial to improve energy consumption predictions and energy policy making how should we quantitatively measure them what are their determinants this study explores the main factors influencing residential energy saving behaviours based on a bottom up multivariate statistical approach using data from the recent french phebus survey firstly we assess energy saving behaviours on a one dimension scale using irt secondly we use linear regression with an innovative variable selection method via adaptive lasso to tease out the effects of both macro and micro factors on the behavioural score the results highlight the impact of five main attributes incentivizing energy saving behaviours based on cross variable analyses energy price household income education level age of head of household and dwelling energy performance in addition our results suggest that the analysis of the inverted u shape impact of age enables the expansion of the energy consumption life cycle theory to energy saving behaviours abstract analysing household energy saving behaviours is crucial to improve energy consumption predictions and energy policy making how should we quantitatively measure them what are their determi nants this study explores the main factors influencing residential energy saving behaviours based on a bottom up multivariate statistical approach using data from the recent french phebus survey firstly we assess energy saving behaviours on a one dimension scale using irt secondly we use linear regression with an innovative variable selection method via adaptive lasso to tease out the effects of both macro and micro factors on the behavioural score the results highlight the impact of five main attributes incentivizing energy saving behaviours based on cross variable analyses energy price household income education level age of head of household and dwelling energy performance in addition our results suggest that the analysis of the inverted u shape impact of age enables the expansion of the energy consumption life cycle theory to energy saving behaviours

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

inflation and money in colombia another p star model this document presents the estimation of a recent version of the p star model by gerlach and svensson 2003 and its predictions for colombia january 1980 to april 2005 the model is designed to explain the inflation gap observed rate minus the target based on the monetary gap and the output gap according to the results the output gap lacks significant effects while the monetary gap has significant positive effects on inflation

underlying energy demand trends in south korean and indonesian aggregate whole economy and residential sectors abstract this paper used annual time series data over the period 1973 2008 to estimate energy demand functions for south korea and indonesian aggregated whole economy and residential sectors furthermore the underlying energy demand trend uedt which may be non linear and reflects not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction is also examined in the paper in estimating the price and income elasticities the study applies harvey s structural time series approach where a stochastic trend is used as a proxy for uedt empirical evidence from this study reveals that the estimated long run income and price elasticities range from 0 58 to 1 15 and from 0 09 to 066 respectively furthermore the stochastic form for the uedt is preferred for both countries and sectors suggesting a wide variation in the exogenous effects of energy saving technical progress in addition to other pertinent exogenous factors such as economic structure consumer preferences and socio economic influences

regulation asymmetric information and auditing this article analyzes a model of a regulated firm that is better informed about its cost function than is the regulator by auditing at a cost however the regulator is assumed to be able to observe the realized cost of the firm if the regulator finds that the firm had misrepresented its costs at the time at which prices were set he can order a refund to consumers in the optimal policy the regulator audits when the firm reports for pricing purposes that its costs will be high and orders a refund when the auditfinds that realized costs are lower than anticipated given the original report a separation result that obtains for an important case indicates that the initial pricing decision is independent of the auditing decision the auditing decision however depends on the price that was initially set the optimal auditing strategy is characterized and the nature of the welfare gains are identified the methodology used in the analysis involves the characterization of an equilibrium of a revelation game with an ex post observable

microfoundations and the demand for money the reader should note that i write this piece in a style that aims to be accessible to that much neglected representative agent the woman on the eurostar train hence unlike the man on the clapham omnibus i assume my intrepid traveller has reasonable knowledge of monetary economics and econometrics but not of the details of the demand for money space constraints force me to indulge in a certain amount of poetic licence but i hope this results in poetic justice there have been many wars fought on this particular battlefield some with almost religious zeal on the theoretical side of the debate we sometimes have the equivalent of religious fundamentalists be they muslims jews christians etc who would dismiss almost any evidence unless it were associated with a strong microtheoretic basis as laid down in the koran talmud or bible the empirical side encompasses agnostics atheists as well as born again econometricians pure theorists inhabit the sunlit uplands while applied economists and policymakers flounder in the muddy plain below occasionally gaining solace from their copy of zen and the art of motorcycle maintenance in general in economics we do not have the luxury of controlled experiments as is the case in the natural sciences what distinguishes good microfoundations from bad and how to weight priors and statistical evidence is subject to much dispute leamer i983 hendry et al i990 as in religion sometimes there is the occasional miracle proclaimed after a suitable interval a new saint may be declared and disciples flock to the new shrine later doubts may arise as to whether a miracle really did occur human behaviour is difficult to explain let alone predict so the search for the equivalent of the holy grail ark of the covenant etc is bound to be arduous in scholarly journals we generally read of the success of the demand for money like diplomats who are sent abroad to lie for the good of their country publication may require applied economists to be somewhat economical with the actualite lovell i983 leamer i983 in this article i want to be as honest as possible about our success and failures in this area the prior information an armchair economist would consider when thinking about the demand for money over the past 40 years in western industrialised countries which have experienced moderate inflation might

accounting for technical progress in aggregate energy demand abstract researchers have not reached a consensus on how to account for technical progress when modeling aggregate energy demand some include a time trend in a dynamic model while others omit the trend in a model that disallows for long run income effects we show that the latter approach can be directly tested as a nested case of the former so that model selection need not be made a priori solely on theoretical grounds using annual data over 1960 1990 we find that long run income effects are not significant however including a time trend improves the model s fit while rendering much more credible long run price elasticities

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

inconsistent regulators evidence from banking we find that regulators can implement identical rules inconsistently due to differences in their institutional design and incentives and this behavior may adversely impact the effectiveness with which regulation is implemented we study supervisory decisions of u s banking regulators and exploit a legally determined rotation policy that assigns federal and state supervisors to the same bank at exogenously set time intervals comparing federal and state regulator supervisory ratings within the same bank we find that federal regulators are systematically tougher downgrading supervisory ratings almost twice as frequently as do state supervisors state regulators counteract these downgrades to some degree by upgrading more frequently under federal regulators banks report worse asset quality higher regulatory capital ratios and lower return on assets leniency of state regulators relative to their federal counterparts is related to costly outcomes such as higher failure rates and lower repayment rates of government assistance funds the discrepancy in regulator behavior is related to different weights given by regulators to local economic conditions and to some extent differences in regulatory resources we find no support for regulator self interest which includes revolving doors

the information content of bank exam ratings and subordinated debt prices do supervisory examinations of large commercial banking firms produce useful information not already reflected in market prices to investigate this question we apply a new research methodology to data on bank exam ratings and the subordinated debt risk spreads of their parent holding companies we find that government exams do produce new value relevant information that debenture prices do not immediately reflect this information and that the market prices the likely regulatory actions implied by this information these results have implications for market versus regulatory discipline at large banking firms and for proposals to make subordinated debt mandatory for these firms

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

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

metaanalisis de las elasticidades ingreso y precio de la demanda de energia algunas implicaciones de politica publica para america latina the aim of this paper is to analyze the variation in empirical estimates of the income and price elasticities of energy demand the evidence presented through a meta analysis allows identification of the weighted average of the income and price elasticities shows that the estimates are very heterogeneous that there is publication bias and that factors such as region energy sector among others affect its volatility the evidence also indicates that income elasticity in latin america is greater than in the oecd countries and that the price elasticity of energy demand is lower in latin america than in the oecd countries therefore continued economic growth in latin america will be accompanied by a growth in energy demand moreover the establishment of a tax in latin america under the current elasticities is less effective and will be insufficient to control the increase in energy consumption

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

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

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

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

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
